"I will take this medication regularly to prevent a migraine headache from occurring." b. "I will take this medication when I feel a migraine headache starting." c. "This medication does not reduce the number of migraines I will have." d. "I will keep a journal to record the headaches I have and how the injections are working."

ANS: A Although they may be taken during aura symptoms by patients who have auras with their headaches, these drugs are not indicated for preventive migraine therapy. The medication is intended to relieve the migraine and not to prevent it or to reduce the number of attacks. The triptans do not reduce the number of migraines a person will have. Journal recordings of headaches and the patient's responses to the medication are helpful.

2. When an adrenergic drug stimulates beta1-adrenergic receptors, the result is an increased force of contraction, which is known as what type of effect? a. Positive inotropic b. Anti-adrenergic c. Negative dromotropic d. Positive chronotropic

ANS: A An increased force of contraction is known as a positive inotropic effect.

7. When applying transdermal nitroglycerin patches, which instruction by the nurse is correct? a. "Rotate application sites with each dose." b. "Use only the chest area for application sites." c. "Temporarily remove the patch if you go swimming." d. "Apply the patch to the same site each time."

ANS: A Application sites for transdermal nitroglycerin patches need to be rotated. Apply the transdermal patch to any nonhairy area of the body; the old patch should first be removed. The patch may be worn while swimming, but if it does come off, it should be replaced after the old site is cleansed.

Pharm Ch 12 CNS Depressants & Muscle Relaxants 1. A patient who has received some traumatic news is panicking and asks for some medication to help settle down. The nurse anticipates giving which drug that is most appropriate for this situation? a. Diazepam (Valium) b. Zolpidem (Ambien) c. Phenobarbital d. Cyclobenzaprine (Flexeril)

ANS: A Benzodiazepines such as diazepam are used as anxiolytics, or sedatives. Zolpidem is used as a hypnotic for sleep. Phenobarbital is not used as an anxiolytic but is used for seizure control. Cyclobenzaprine is a muscle relaxant and is not used to reduce anxiety.

Pharm Ch 16 Psychotherapeutic Drugs 1. The nurse reads in the patient's medication history that the patient is taking buspirone (BuSpar). The nurse interprets that the patient may have which disorder? a. Anxiety disorder b. Depression c. Schizophrenia d. Bipolar disorder

ANS: A Buspirone is indicated for the treatment of anxiety disorders, not depression, schizophrenia, or bipolar disorder.

9. A patient taking entacapone (Comtan) for the first time calls the clinic to report a dark discoloration of his urine. After listening to the patient, the nurse realizes that what is happening in this situation? a. This is a harmless effect of the drug. b. The patient has taken this drug along with red wine or cheese. c. The patient is having an allergic reaction to the drug. d. The ordered dose is too high for this patient.

ANS: A COMT inhibitors, including entacapone, may darken a patient's urine and sweat.

The nurse shares that caffeine should be used with caution if which of these conditions is present? a. A history of peptic ulcers b. Migraine headaches c. Asthma d. A history of kidney stones

ANS: A Caffeine should be used with caution by patients who have histories of peptic ulcers or cardiac dysrhythmias or who have recently had myocardial infarctions. The other conditions are not contraindications to the use of caffeine.

8. During a teaching session about self-monitoring while taking a beta blocker at home, the nurse has taught the patient to take his apical pulse daily for 1 minute. If the pulse rate decreases to less than 60 beats/min, the nurse will instruct the patient to: a. notify his prescriber. b. reduce the dose of his beta blocker by half. c. continue the medication because this is an expected effect. d. skip the medication dose that day, and check his pulse again the next day.

ANS: A Cardiac depression can occur with beta blockers; instruct the patient to contact his prescriber if his pulse rate decreases to less than 60 per minute. The medication dose may need to be changed, but it is not appropriate for the nurse to change the dosage. The other options are incorrect.

Pharm Ch 21 Cholinergic-Blocking Drugs 1. The nurse is about to administer a stat dose of intravenous atropine sulfate to a patient who is experiencing a symptomatic cardiac dysrhythmia. During administration of this drug, the nurse will monitor the patient closely for which adverse effect? a. Tachycardia b. Bradycardia c. Ectopic beats d. Cardiac standstill

ANS: A Cardiovascular effects of cholinergic blockers include increased heart rate and dysrhythmias. One indication for use is the treatment of sinus bradycardia accompanied by hemodynamic compromise. The other options are incorrect.

4. A 74-year-old professional golfer has chest pain that occurs toward the end of his golfing games. He says the pain usually goes away after one or two sublingual nitroglycerin tablets and rest. What type of angina is he experiencing? a. Classic b. Variant c. Unstable d. Prinzmetal's

ANS: A Classic, or chronic stable, angina is triggered by either exertion or stress and usually subsides within 15 minutes with either rest or drug therapy.

9. During assessment of a patient with osteoarthritis pain, the nurse knows that which condition is a contraindication to the use of nonsteroidal anti-inflammatory drugs (NSAIDs)? a. Renal disease b. Diabetes mellitus c. Headaches d. Rheumatoid arthritis

ANS: A Contraindications to NSAIDs include known drug allergy and conditions that place a patient at risk for bleeding, such as vitamin K deficiency, and peptic ulcer disease. Patients with documented aspirin allergy must not receive NSAIDs. Other common contraindications are those that apply to most drugs, including severe renal or hepatic disease. The other options are not contraindications.

9. The nurse notes in the patient's medication history that the patient is taking cyclobenzaprine (Flexeril). Based on this finding, the nurse interprets that the patient has which disorder? a. A musculoskeletal injury b. Insomnia c. Epilepsy d. Agitation

ANS: A Cyclobenzaprine (Flexeril) is the muscle relaxant most commonly used to reduce spasms following musculoskeletal injuries. It is not appropriate for insomnia, epilepsy, or agitation.

6. A 22-year-old patient has been taking lithium for 1 year, and the most recent lithium level is 0.9 mEq/L. Which statement about the laboratory result is correct? a. The lithium level is therapeutic. b. The lithium level is too low. c. The lithium level is too high. d. Lithium is not usually monitored with blood levels.

ANS: A Desirable long-term maintenance lithium levels range between 0.6 and 1.2 mEq/L. The other responses are incorrect.

8. A patient is experiencing status epilepticus. The nurse prepares to give which drug of choice for the treatment of this condition? a. Diazepam (Valium) b. Midazolam (Versed) c. Valproic acid (Depakote) d. Carbamazepine (Tegretol)

ANS: A Diazepam (Valium) is considered by many to be the drug of choice for status epilepticus. Other drugs that are used are listed in Table 14-3 and do not include the drugs listed in the other options.

12. A patient is taking gabapentin (Neurontin), and the nurse notes that there is no history of seizures on his medical record. What is the best possible rationale for this medication order? a. The medication is used for the treatment of neuropathic pain. b. The medication is helpful for the treatment of multiple sclerosis. c. The medication is used to reduce the symptoms of Parkinson's disease. d. The medical record is missing the correct information about the patient's history of seizures.

ANS: A Gabapentin (Neurontin) is commonly used to treat neuropathic pain. The other options are incorrect.

9. Phenytoin (Dilantin) has a narrow therapeutic index. The nurse recognizes that this characteristic indicates which of these? a. The safe and the toxic plasma levels of the drug are very close to each other. b. The phenytoin has a low chance of being effective. c. There is no difference between safe and toxic plasma levels. d. A very small dosage can result in the desired therapeutic effect.

ANS: A Having a "narrow therapeutic index" means that there is a small difference between safe and toxic drug levels. These drugs require monitoring of therapeutic plasma levels. The other options are incorrect.

8. In assessing a patient before administration of a cardiac glycoside, the nurse knows that which lab result can increase the toxicity of the drug? a. Potassium level 2.8 mEq/L b. Potassium level 4.9 mEq/L c. Sodium level 140 mEq/L d. Calcium level 10 mg/dL

ANS: A Hypokalemia increases the chance of digitalis toxicity. The other levels listed are incorrect.

5. A patient arrives in the emergency department with severe chest pain. The patient reports that the pain has been occurring off and on for a week now. Which assessment finding would indicate the need for cautious use of nitrates and nitrites? a. Blood pressure of 88/62 mm Hg b. Apical pulse rate of 110 beats/min c. History of renal disease d. History of a myocardial infarction 2 years ago

ANS: A Hypotension is a possible contraindication to the use of nitrates because the medications may cause the blood pressure to decrease. The other options are incorrect.

7. The U.S. Food and Drug Administration has issued a warning for users of antiepileptic drugs. Based on this report, the nurse will monitor for which potential problems with this class of drugs? a. Increased risk of suicidal thoughts and behaviors b. Signs of bone marrow depression c. Indications of drug addiction and dependency d. Increased risk of cardiovascular events, such as strokes

ANS: A In December 2008, the U.S. Food and Drug Administration (FDA) required black box warnings on all antiepileptic drugs regarding the risk of suicidal thoughts and behaviors. Patients being treated with antiepileptic drugs for any indication need to be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, or any unusual changes in mood or behavior. The other options are incorrect.

3. When a patient is taking an adrenergic drug, the nurse expects to observe which effect? a. Increased heart rate b. Bronchial constriction c. Constricted pupils d. Increased intestinal peristalsis

ANS: A Increased heart rate is one of the effects of adrenergic drugs. Sympathetic nervous system stimulation also results in bronchodilation, dilated pupils, and decreased gastrointestinal mobility, depending upon which receptors are stimulated.

5. A patient is recovering from a minor automobile accident that occurred 1 week ago. He is taking cyclobenzaprine (Flexeril) for muscular pain and goes to physical therapy three times a week. Which nursing diagnosis would be appropriate for him? a. Risk for injury related to decreased sensorium b. Risk for addiction related to psychologic dependency c. Decreased fluid volume related to potential adverse effects d. Disturbed sleep pattern related to the drug's interference with REM sleep

ANS: A Musculoskeletal relaxants have a depressant effect on the CNS; thus, the patient needs to be taught the importance of taking measures to minimize self-injury and falls related to decreased sensorium. "Risk for addiction" is not a NANDA nursing diagnosis. The other nursing diagnoses are not appropriate for this situation.

6. A patient is taking flurazepam (Dalmane) three to four nights a week for sleeplessness. She is concerned that she cannot get to sleep without taking the medication. What nonpharmacologic measures should the nurse suggest to promote sleep for this patient? a. Providing a quiet environment b. Exercising before bedtime to become tired c. Consuming heavy meals in the evening to promote sleepiness d. Drinking hot tea or coffee just before bedtime

ANS: A Nonpharmacologic approaches to induce sleep include providing a quiet environment, avoiding heavy exercise before bedtime, avoiding heavy meals late in the evening, and drinking warm decaffeinated drinks, such as warm milk, before bedtime.

11. When administering digoxin immune Fab (Digibind) to a patient with severe digoxin toxicity, the nurse knows that each vial can bind with how much digoxin? a. 0.5 mg b. 5 mg c. 5.5 mg d. 15 mg

ANS: A One vial of digoxin immune Fab binds 0.5 mg of digoxin. The other options are incorrect.

11. A patient is taking an alpha blocker as treatment for benign prostatic hyperplasia. The nurse will monitor for which potential drug effect? a. Orthostatic hypotension b. Increased blood pressure c. Decreased urine flow d. Discolored urine

ANS: A Orthostatic hypotension can occur with any dose of an alpha blocker, and patients must be warned to get up slowly from a supine position. The other responses are not drug effects of alpha blockers.

2. A patient is going home with a new prescription for the beta-blocker atenolol (Tenormin). The nurse will include which content when teaching the patient about this drug? a. Never stop taking this medication abruptly. b. The medication will be stopped once symptoms subside. c. If adverse effects occur, stop taking the drug for 24 hours, and then resume. d. Be watchful for first-dose hypotension.

ANS: A Patients need to be weaned off these medications slowly because rebound hypertension and chest pain are possible with abrupt withdrawal. The drugs should never be stopped abruptly nor doses skipped. First-dose hypotension occurs with alpha blockers.

8. The nurse is conducting a smoking-cessation program. Which statement regarding drugs used in cigarette-smoking-cessation programs is true? a. Rapid chewing of the nicotine gum releases an immediate dose of nicotine. b. Quick relief from withdrawal symptoms is most easily achieved by using a transdermal patch. c. Compliance with treatment is higher with use of the gum rather than the transdermal patch. d. The nicotine gum can be used only up to six times per day.

ANS: A Quick or acute relief from withdrawal symptoms is most easily achieved with the use of the gum because rapid chewing of the gum produces an immediate dose of nicotine. However, treatment compliance is higher with the use of the transdermal patch system. Nicotine gum can be used whenever the patient has a strong urge to smoke.

2. The nurse has given medication instructions to a patient receiving phenytoin (Dilantin). Which statement by the patient indicates that the patient has an adequate understanding of the instructions? a. "I will need to take extra care of my teeth and gums while on this medication." b. "I can go out for a beer while on this medication." c. "I can skip doses if the side effects bother me." d. "I will be able to stop taking this drug once the seizures stop."

ANS: A Scrupulous dental care is necessary to prevent gingival hypertrophy during therapy with phenytoin. Alcohol and other central nervous system depressants may cause severe sedation. Consistent dosing is important to maintain therapeutic drug levels. Therapy with AEDs usually must continue for life and must not be stopped once seizures stop.

2. A patient is taking digoxin (Lanoxin) and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, "I am seeing a funny yellow color around the lights." What is the nurse's next action? a. Assess the patient for symptoms of digoxin toxicity. b. Withhold the next dose of the diuretic. c. Administer the digoxin and diuretic together as ordered. d. Document this finding, and reassess in 1 hour.

ANS: A Seeing colors around lights is one potential indication of developing digoxin toxicity. If a patient complains of this, the nurse needs to assess for other signs and symptoms of digoxin toxicity including bradycardia, headache, dizziness, confusion, nausea, and blurred vision, and then notify the prescriber. Administering the drug or withholding the diuretic are incorrect options.

Pharm Ch 20 Cholinergic Drugs 1. When monitoring a patient who is taking a low-dose cholinergic drug, the nurse will watch for which cardiovascular effect? a. Bradycardia b. Tachycardia c. Vasoconstriction d. Palpitations

ANS: A The cardiovascular effects of low doses of cholinergic drugs are decreased heart rate (not tachycardia) and vasodilation. Palpitations are not effects of cholinergic drugs.

11. A patient calls the clinic to ask about taking a glucosamine-chondroitin supplement for arthritis. The nurse reviews the medication history and notes that there will be a concern for drug interactions if the patient is also taking medications for which disorder? a. Type 2 diabetes mellitus b. Hypothyroidism c. Hypertension d. Angina

ANS: A The glucosamine in glucosamine-chondroitin supplements may cause an increase in insulin resistance, necessitating the need for higher doses of oral hypoglycemics or insulin.

3. A patient with gout has been treated with allopurinol (Zyloprim) for 2 months. The nurse will monitor laboratory results for which therapeutic effect? a. Decreased uric acid levels b. Decreased prothrombin time c. Decreased white blood cell count d. Increased hemoglobin and hematocrit levels

ANS: A Treatment of gout with allopurinol should result in decreased uric acid levels. The other options are incorrect.

2. Which drug classes are considered first-line treatment for heart failure? (Select all that apply.) a. Angiotensin-converting enzyme (ACE) inhibitors b. Angiotensin II receptor blockers (ARBs) c. Digoxin (cardiac glycoside) d. Beta blockers e. Nesiritide (Natrecor), the B-type natriuretic peptide

ANS: A, B, D ACE inhibitors, ARBs, and beta blockers are now considered the first-line treatments for heart failure. Digoxin is used when the first-line treatments are not successful; nesiritide is considered a last-resort treatment.

2. The barbiturate phenobarbital is prescribed for a patient with epilepsy. While assessing the patient's current medications, the nurse recognizes that interactions may occur with which drugs? (Select all that apply.) a. Antihistamines b. Opioids c. Diuretics d. Anticoagulants e. Oral contraceptives f. Insulin

ANS: A, B, D, E The co-administration of barbiturates and alcohol, antihistamines, benzodiazepines, opioids, and tranquilizers may result in additive CNS depression. Co-administration of anticoagulants and barbiturates can result in decreased anticoagulation response and possible clot formation. Co-administration of barbiturates and oral contraceptives can result in accelerated metabolism of the contraceptive drug and possible unintended pregnancy. There are no interactions with diuretics and insulin.

1. A beta blocker is prescribed for a patient with angina. The nurse reviews the orders for other drugs that may interact with the beta blocker. Which drugs or drug classes are known to have an interaction with a beta blocker? (Select all that apply.) a. Diuretics b. Anticholinergics c. Penicillins d. Oral hypoglycemics e. Alcohol f. Anticoagulants

ANS: A, B, D, E When taken with beta blockers, diuretics and alcohol may cause additive hypotensive effects; oral hypoglycemic medications may cause the blood glucose to decrease; and anticholinergics may cause decreased beta-blocker effects. Penicillins and anticoagulants are not known to interact with beta blockers.

1. When assessing the medication history of a patient with a new diagnosis of Parkinson's disease, which conditions are contraindications for the patient who will be taking carbidopa-levodopa? (Select all that apply.) a. Angle-closure glaucoma b. History of malignant melanoma c. Hypertension d. Benign prostatic hyperplasia e. Concurrent use of monoamine oxidase inhibitors (MAOIs)

ANS: A, B, E Angle-closure glaucoma, a history of melanoma or other undiagnosed skin conditions, and concurrent use of MAOIs are contraindications to the use of carbidopa-levodopa. The other options are incorrect.

1. The nurse is reviewing the history of a patient who has a new order for a nonsteroidal anti-inflammatory drug (NSAID) to treat tendonitis. Which conditions are contraindications to the use of NSAIDs? (Select all that apply.) a. Vitamin K deficiency b. Arthralgia c. Peptic ulcer disease d. Neuropathy e. Pericarditis

ANS: A, C Contraindications to NSAIDs include known drug allergy as well as conditions that place the patient at risk for bleeding, such as Vitamin K deficiency and peptic ulcer disease. NSAIDs may be used to treat arthralgia and pericarditis. Neuropathy is not a contraindication.

3. The nurse is monitoring a patient who is experiencing severe ethanol withdrawal. Which are signs and symptoms of severe ethanol withdrawal? (Select all that apply.) a. Agitation b. Drowsiness c. Tremors d. Systolic blood pressure higher than 200 mm Hg e. Temperature over 100° F (37.7° C) f. Pulse rate 110 beats/min

ANS: A, C, D Signs and symptoms of severe ethanol withdrawal (delirium tremens) include systolic blood pressure higher than 200 mm Hg, diastolic blood pressure higher than 140 mm Hg, pulse rate higher than 140 beats/min, temperature above 101° F (38.3° C), tremors, insomnia, and agitation. See Box 17-6 for all signs and symptoms of ethanol withdrawal.

1. A patient who has been taking a selective serotonin reuptake inhibitor (SSRI) is complaining of "feeling so badly" when he started taking an over-the-counter St. John's wort herbal product at home. The nurse suspects that he is experiencing serotonin syndrome. Which of these are symptoms of serotonin syndrome? (Select all that apply.) a. Agitation b. Drowsiness c. Tremors d. Bradycardia e. Sweating f. Constipation

ANS: A, C, E Common symptoms of serotonin syndrome include delirium, agitation, tachycardia, sweating, hyperreflexia, shivering, coarse tremors, and others. See Box 16-1 for a full list of symptoms.

1. The nurse is providing education about the use of sublingual nitroglycerin tablets. She asks the patient, "What would you do if you experienced chest pain while mowing your yard? You have your bottle of sublingual nitroglycerin with you." Which actions by the patient are appropriate in this situation? (Select all that apply.) a. Stop the activity, and lie down or sit down. b. Call 911 immediately. c. Call 911 if the pain is not relieved after taking one sublingual tablet. d. Call 911 if the pain is not relieved after taking three sublingual tablets in 15 minutes. e. Place a tablet under the tongue. f. Place a tablet in the space between the gum and cheek. g. Take another sublingual tablet if chest pain is not relieved after 5 minutes, up to three total.

ANS: A, C, E, G With sublingual forms, the medication is taken at the first sign of chest pain, not delayed until the pain is severe. The patient needs to sit down or lie down and take one sublingual tablet. According to current guidelines, if the chest pain or discomfort is not relieved in 5 minutes, after 1 dose, the patient (or family member) must call 911 immediately. The patient can take one more tablet while awaiting emergency care and may take a third tablet 5 minutes later, but no more than a total of three tablets. These guidelines reflect the fact that angina pain that does not respond to nitroglycerin may indicate a myocardial infarction. The sublingual dose is placed under the tongue, and the patient needs to avoid swallowing until the tablet has dissolved. Placing a tablet between the gum and cheek is the buccal route.

1. The nurse is reviewing the use of central nervous system stimulants. Which of these are indications for this class of drugs? (Select all that apply.) a. Narcolepsy b. Depression c. Panic attacks d. Neonatal apnea e. Attention deficit hyperactivity disorder (ADHD) f. Appetite suppression

ANS: A, D, E, F Central nervous system stimulants can be used for narcolepsy, neonatal apnea, ADHD, and appetite suppression in the treatment of obesity. They are not used for depression and panic attacks.

1. The nurse is presenting information to a class of students about adrenergic drugs. Which are the effects of drugs that stimulate the sympathetic nervous system? (Select all that apply.) a. Dilation of bronchioles b. Constriction of bronchioles c. Decreased heart rate d. Increased heart rate e. Dilated pupils f. Constricted pupils g. Glycogenolysis

ANS: A, D, E, G Stimulation of the sympathetic nervous system causes bronchodilation, increased heart rate, pupil dilation, and glycogenolysis as well as many other effects (see Table 18-1). The other responses are effects that occur as a result of the stimulation of the parasympathetic nervous system.

1. The nurse is reviewing the indications for atropine sulfate. Atropine is appropriate for which of these patients? (Select all that apply.) a. A patient who has suddenly developed symptomatic bradycardia with a heart rate of 32 beats/min b. A patient who has suddenly developed symptomatic tachycardia with a heart rate of 180 beats/min c. A patient with severe narrow-angle glaucoma d. A patient who is about to have surgery e. A patient newly diagnosed with myasthenia gravis f. A patient with anticholinesterase inhibitor poisoning

ANS: A, D, F Anticholinergic drugs are used for symptomatic bradycardia and certain other cardiac conditions. It is given preoperatively to control secretions during surgery and is used as an antidote for anticholinesterase inhibitor poisoning. The other options are contraindications to the use of atropine.

6. A patient has a digoxin level of 1.1 ng/mL. Which interpretation by the nurse is correct? a. It is below the therapeutic level. b. It is within the therapeutic range. c. It is above the therapeutic level. d. It is at a toxic level.

ANS: B The normal therapeutic drug level of digoxin is between 0.5 and 2 ng/mL. The other options are incorrect.

3. While assessing a patient who is receiving intravenous digitalis, the nurse recognizes that the drug has a negative chronotropic effect. How would this drug effect be evident in the patient? a. Decreased blood pressure b. Decreased heart rate c. Decreased conduction d. Decreased ectopic beats

ANS: B A negative chronotropic effect results in a decreased heart rate; this is one effect of cardiac glycosides. The other options are incorrect.

10. A patient has been taking an AED for several years as part of his treatment for partial seizures. His wife has called because he ran out of medication this morning and wonders if he can go without it for a week until she has a chance to go to the drugstore. What is the nurse's best response? a. "He is taking another antiepileptic drug, so he can go without the medication for a week." b. "Stopping this medication abruptly may cause withdrawal seizures. A refill is needed right away." c. "He can temporarily increase the dosage of his other antiseizure medications until you get the refill." d. "He can stop all medications because he has been treated for several years now."

ANS: B Abrupt discontinuation of antiepileptic drugs can lead to withdrawal seizures. The other options are incorrect. The nurse cannot change the dose or stop the medication without a prescriber's order.

3. A 50-year-old man who has been taking phenobarbital for 1 week is found very lethargic and unable to walk after eating out for dinner. His wife states that he has no other prescriptions and that he did not take an overdose—the correct number of pills is in the bottle. The nurse suspects that which of these may have happened? a. He took a multivitamin. b. He drank a glass of wine. c. He took a dose of aspirin. d. He developed an allergy to the drug.

ANS: B Alcohol has an additive effect when combined with barbiturates and causes central nervous system (CNS) depression. Multivitamins and aspirin do not interact with barbiturates, and this situation does not illustrate an allergic reaction.

10. The nurse notes in a patient's medication history that the patient is taking allopurinol (Zyloprim). Based on this finding, the nurse interprets that the patient has which disorder? a. Rheumatoid arthritis b. Gout c. Osteoarthritis d. Systemic lupus erythematosus

ANS: B Allopurinol is indicated for the treatment of gout but is not indicated for the other disorders listed.

11. A patient is receiving gabapentin (Neurontin), an anticonvulsant, but has no history of seizures. The nurse expects that the patient is receiving this drug for which condition? a. Inflammation pain b. Pain associated with peripheral neuropathy c. Depression associated with chronic pain d. Prevention of seizures

ANS: B Anticonvulsants are often used as adjuvants for treatment of neuropathic pain to enhance analgesic efficacy. The other indications listed are not correct.

5. A 10-year-old patient will be started on methylphenidate hydrochloride (Ritalin) therapy. The nurse will perform which essential baseline assessment before this drug is started? a. Eye examination b. Height and weight c. Liver function studies d. Hearing test

ANS: B Assessment of baseline height and weight is important before beginning Ritalin therapy because it may cause a temporary slowing of growth in prepubertal children. The other studies are not as essential at this time.

Pharm Ch 15 Antiparkinson Drugs 1. A patient has been taking selegiline (Eldepryl), 20 mg/day for 1 month. Today, during his office visit, he tells the nurse that he forgot and had a beer with dinner last evening, and "felt awful." What did the patient most likely experience? a. Hypotension b. Hypertension c. Urinary discomfort d. Gastrointestinal upset

ANS: B At doses that exceed 10 mg/day, selegiline becomes a nonselective monoamine oxidase inhibitor (MAOI), contributing to the development of the cheese effect, so-called because it interacts with tyramine-containing foods (cheese, red wine, beer, and yogurt) and can cause severe hypertension.

9. A patient who has been diagnosed with Sjögren's syndrome will be given cevimeline for the treatment of xerostomia. The nurse will monitor for what therapeutic effect? a. Reduction of salivation b. Stimulation of salivation c. Reduction of gastrointestinal peristalsis d. Improvement of fine-motor control

ANS: B Cevimeline is a direct-acting cholinergic drug that is used to stimulate salivation in patients who have xerostomia (dry mouth), one of the manifestations of Sjögren's syndrome. The other options are incorrect.

10. In preparation for eye surgery, the nurse monitors for which desired drug effect in a patient who is receiving a cholinergic-blocking eyedrop medication? a. Miosis b. Mydriasis c. Increased intraocular fluid production d. Enhanced tear production

ANS: B Cholinergic-blocking eyedrops cause dilation of the pupil (mydriasis) and paralysis of the ocular lens (cycloplegia), both of which are important for eye surgery. The other options are incorrect.

Pharm Ch 10: Analgesic Drugs 1. A patient was diagnosed with pancreatic cancer last month, and has complained of a dull ache in the abdomen for the past 4 months. This pain has been gradually increasing, and the pain relievers taken at home are no longer effective. What type of pain is the patient experiencing? a. Acute pain b. Chronic pain c. Somatic pain d. Neuropathic pain

ANS: B Chronic pain is associated with cancer and is characterized by slow onset, long duration, and dull, persistent aching. The patient's symptoms are not characteristics of acute pain, somatic pain, or neuropathic pain.

Pharm Ch 17 Substance Use Disorder 1. A 38-year-old male patient stopped smoking 6 months ago. He tells the nurse that he still feels strong cigarette cravings and wonders if he is ever going to feel "normal" again. Which statement by the nurse is correct? a. "It's possible that these cravings will never stop." b. "These cravings may persist for several months." c. "The cravings tell us that you are still using nicotine." d. "The cravings show that you are about to experience nicotine withdrawal."

ANS: B Cigarette cravings may persist for months after nicotine withdrawal. The other statements are false.

10. A patient has a new prescription for tamsulosin (Flomax) as treatment for benign prostatic hyperplasia. The nurse is checking his current medication list and will contact the prescriber regarding a potential interaction if the patient is also taking which drug? a. Levothyroxine (Synthroid) for hypothyroidism b. Sildenafil (Viagra), an erectile dysfunction medication c. Omeprazole (Prilosec), a proton pump inhibitor d. Low-dose aspirin for stroke prevention

ANS: B Drugs that interact with alpha blockers such as tamsulosin include erectile dysfunction drugs; additive hypotensive effects may occur. The other drugs do not interact with tamsulosin.

10. While a patient is receiving drug therapy for Parkinson's disease, the nurse monitors for dyskinesia, which is manifested by which finding? a. Rigid, tense muscles b. Difficulty in performing voluntary movements c. Limp extremities with weak muscle tone d. Confusion and altered mental status

ANS: B Dyskinesia is the difficulty in performing voluntary movements that is experienced by some patients with Parkinson's disease. The other options are incorrect.

14. A patient wants to take a ginseng dietary supplement. The nurse instructs the patient to look for which potential adverse effect? a. Drowsiness b. Palpitations and anxiety c. Dry mouth d. Constipation

ANS: B Elevated blood pressure, chest pain or palpitations, anxiety, insomnia, headache, nausea, vomiting, and diarrhea are potential adverse effects of ginseng. Drowsiness, difficulty with urination, and constipation are not potential adverse effects of ginseng.

8. A hospitalized patient is experiencing a severe anaphylactic reaction to a dose of intravenous penicillin. Which drug will the nurse expect to use to treat this condition? a. Ephedra b. Epinephrine c. Phenylephrine d. Pseudoephedrine

ANS: B Epinephrine is the drug of choice for the treatment of anaphylaxis. The other drugs listed are incorrect choices.

Pharm Ch 19 Adrenergic-Blocking Drugs 1. During therapy with a beta blocker, the patient notices that she has swollen feet, has gained 3 pounds within 2 days, feels short of breath even when walking around the house, and has been dizzy. The nurse suspects that which of these is occurring? a. The patient is experiencing an allergic reaction. b. The patient may be developing heart failure. c. More time is needed for the patient to see a therapeutic response to the drug. d. The patient is experiencing expected adverse effects of the drug.

ANS: B Even though some beta blockers may be used for the treatment of some types of heart failure, the patient needs to be assessed often for the development of heart failure, a potential adverse effect of the drugs. These symptoms do not indicate expected adverse effects, an allergic reaction, or a therapeutic response.

9. The nurse is reviewing herbal therapies. Which is a common use of the herb feverfew? a. Muscle aches b. Migraine headaches c. Leg cramps d. Incision pain after surgery

ANS: B Feverfew is commonly used for migraine headaches, menstrual problems, arthritis, and fever. Possible adverse effects include muscle stiffness and muscle and joint pain.

4. The nurse is presenting a substance-abuse lecture for teenage girls and is asked about "roofies." The nurse recognizes that this is the slang term for which substance? a. Cocaine b. Flunitrazepam c. Secobarbital d. Methamphetamine

ANS: B Flunitrazepam is a benzodiazepine that has recently gained popularity as a recreational drug and is commonly called roofies (the "date-rape" drug). The other drugs are not known as roofies.

4. An adrenergic agonist is ordered for a patient in shock. The nurse will note that this drug has had its primary intended effect if which expected outcome occurs? a. Volume restoration b. Increased cardiac output c. Decreased urine output d. Reduced anxiety

ANS: B For a patient in shock, a primary benefit of an adrenergic agonist drug is to increase cardiac output. A drug in this category should not be used in place of volume restoration, nor does it provide volume restoration (IV fluids do this). Adrenergic agonists may enhance urine output if cardiac output and perfusion to the kidneys increase. These drugs do not reduce anxiety.

8. A 57-year-old woman being treated for end-stage breast cancer has been using a transdermal opioid analgesic as part of the management of pain. Lately, she has been experiencing breakthrough pain. The nurse expects this type of pain to be managed by which of these interventions? a. Administering NSAIDs b. Administering an immediate-release opioid c. Changing the opioid route to the rectal route d. Making no changes to the current therapy

ANS: B If a patient is taking long-acting opioid analgesics, breakthrough pain must be treated with an immediate-release dosage form that is given between scheduled doses of the long-acting opioid. The other options are not appropriate actions.

9. While monitoring a depressed patient who has just started SSRI antidepressant therapy, the nurse will observe for which problem during the early time frame of this therapy? a. Hypertensive crisis b. Self-injury or suicidal tendencies c. Extrapyramidal symptoms d. Loss of appetite

ANS: B In 2005, the U.S. Food and Drug Administration (FDA) issued special black-box warnings regarding the use of all classes of antidepressants in both adult and pediatric patient populations. Data from the FDA indicated a higher risk for suicide in patients receiving these medications. As a result, current recommendations for all patients receiving antidepressants include regular monitoring for signs of worsening depressive symptoms, especially when the medication is started or the dosage is changed. The other options are incorrect.

6. The nurse is giving an intravenous dose of phenytoin (Dilantin). Which action is correct when administering this drug? a. Give the dose as a fast intravenous (IV) bolus. b. Mix the drug with normal saline, and give it as a slow IV push. c. Mix the drug with dextrose (D5W), and give it as a slow IV push. d. Mix the drug with any available solution as long as the administration rate is correct.

ANS: B Intravenous phenytoin is given only with normal saline solution to prevent precipitation formation caused by incompatibilities. The IV push dose must be given slowly (not exceeding 50 mg/min in adults), and the patient must be monitored for bradycardia and decreased blood pressure.

10. The nurse is reviewing the mechanism of action of cholinergic drugs. The undesired effects of cholinergic drugs come from the stimulation of which receptors? a. Muscarinic b. Nicotinic c. Cholinergic d. Ganglionic

ANS: B Many of the undesirable adverse effects are due to nicotinic receptor stimulation. The desired effects come from muscarinic receptor stimulation. The other options are incorrect.

10. The nurse notes in a patient's medical record that nesiritide (Natrecor) has been ordered. Based on this order, the nurse interprets that the patient has which disorder? a. Atrial fibrillation b. Acutely decompensated heart failure with dyspnea at rest c. Systolic heart failure d. Chronic, stable heart failure

ANS: B Nesiritide is indicated for the treatment of acutely decompensated heart failure with dyspnea at rest. Digoxin is used for the treatment of atrial fibrillation and systolic heart failure. Nesiritide is not indicated for chronic, stable heart failure.

7. A patient is experiencing diastolic heart failure. The nurse expects which beta blocker to be ordered for this patient? a. Atenolol (Tenormin) b. Carvedilol (Coreg) c. Acebutolol (Sectral) d. Esmolol (Brevibloc)

ANS: B Not all beta blockers are used for the treatment of heart failure. Carvedilol and metoprolol are currently used in the treatment of heart failure. The other options are not indicated for the treatment of heart failure.

3. A patient is recovering from abdominal surgery, which he had this morning. He is groggy but complaining of severe pain around his incision. What is the most important assessment data to consider before the nurse administers a dose of morphine sulfate to the patient? a. His pulse rate b. His respiratory rate c. The appearance of the incision d. The date of his last bowel movement

ANS: B One of the most serious adverse effects of opioids is respiratory depression. The nurse must assess the patient's respiratory rate before administering an opioid. The other options are incorrect.

6. A patient has been treated for lung cancer for 3 years. Over the past few months, the patient has noticed that the opioid analgesic is not helping as much as it had previously and more medication is needed for the same pain relief. The nurse is aware that this patient is experiencing which of these? a. Opioid addiction b. Opioid tolerance c. Opioid toxicity d. Opioid abstinence syndrome

ANS: B Opioid tolerance is a common physiologic result of long-term opioid use. Patients with opioid tolerance require larger doses of the opioid agent to maintain the same level of analgesia. This situation does not describe toxicity (overdose), addiction, or abstinence syndrome (withdrawal).

2. A patient in a rehabilitation center is beginning to experience opioid withdrawal symptoms. The nurse expects to administer which drug as part of the treatment? a. Diazepam (Valium) b. Methadone c. Disulfiram (Antabuse) d. Bupropion (Zyban)

ANS: B Opioid withdrawal can be managed with either methadone or clonidine (Catapres). Diazepam and disulfiram are used for treatment of alcoholism, and bupropion is used to assist with smoking cessation.

11. The wife of a patient who has been diagnosed with depression calls the office and says, "It's been an entire week since he started that new medicine for his depression, and there's no change! What's wrong with him?" What is the nurse's best response? a. "The medication may not be effective for him. He may need to try another type." b. "It may take up to 6 weeks to notice any therapeutic effects. Let's wait a little longer to see how he does." c. "It sounds like the dose is not high enough. I'll check about increasing the dosage." d. "Some patients never recover from depression. He may not respond to this therapy."

ANS: B Patients and family members need to be told that antidepressant drugs commonly require several weeks before full therapeutic effects are noted. The other answers are incorrect.

7. The nurse is developing a care plan for a patient who is taking an anticholinergic drug. Which nursing diagnosis would be appropriate for this patient? a. Diarrhea b. Urinary retention c. Risk for infection d. Disturbed sleep pattern

ANS: B Patients receiving anticholinergic drugs are at risk for urinary retention and constipation, not diarrhea. The other nursing diagnoses are not applicable to anticholinergic drugs.

Pharm Ch 14 Antiepileptic Drugs 1. The nurse is reviewing the dosage schedule for several different antiepileptic drugs (AEDs). Which antiepileptic drug allows for once-a-day dosing? a. Levetiracetam (Keppra) b. Phenobarbital c. Valproic acid (Depakote) d. Gabapentin (Neurontin)

ANS: B Phenobarbital has the longest half-life of all standard AEDs, including those listed in the other options, so it allows for once-a-day dosing.

2. The nurse notes in a patient's medication history that the patient is taking pilocarpine (Pilocar). Based on this finding, the nurse interprets that the patient has which disorder? a. Anticholinergic poisoning b. Glaucoma c. Bladder atony d. Myasthenia gravis

ANS: B Pilocarpine is a direct-acting drug that is used topically to reduce intraocular pressure in patients with glaucoma. The other disorders are not indications for pilocarpine.

12. Chlorpromazine (Thorazine) is prescribed for a patient, and the nurse provides instructions to the patient about the medication. The nurse includes which information? a. The patient needs to avoid caffeine while on this drug. b. The patient needs to wear sunscreen while outside because of photosensitivity. c. Long-term therapy may result in nervousness and excitability. d. The medication may be taken with an antacid to reduce gastrointestinal upset.

ANS: B Sun exposure and tanning booths need to be avoided with conventional antipsychotics because of the adverse effect of photosensitivity. Instruct the patient to apply sunscreen liberally and to wear sun-protective clothing and hats.

3. When a patient is receiving a second-generation antipsychotic drug, such as risperidone (Risperdal), the nurse will monitor for which therapeutic effect? a. Fewer panic attacks b. Decreased paranoia and delusions c. Decreased feeling of hopelessness d. Improved tardive dyskinesia

ANS: B The therapeutic effects of the antipsychotic drugs include improvement in mood and affect, and alleviation or decrease in psychotic symptoms (decrease in hallucinations, paranoia, delusions, garbled speech). Tardive dyskinesia is a potential adverse effect of these drugs. The other options are incorrect.

7. A patient is being treated for ethanol alcohol abuse in a rehabilitation center. The nurse will include which information when teaching him about disulfiram (Antabuse) therapy? a. He should not smoke cigarettes while on this drug. b. He needs to know about the common over-the-counter substances that contain alcohol. c. This drug will cause the same effects as the alcohol did, without the euphoric effects. d. Mouthwashes and cough medicines that contain alcohol are safe because they are used in small amounts.

ANS: B The use of disulfiram (Antabuse) with alcohol-containing over-the-counter products will elicit severe adverse reactions. As little as 7 mL of alcohol may cause symptoms in a sensitive person. Cigarette smoking does not cause problems when taking disulfiram. Disulfiram does not have the same effects as alcohol.

2. Before beginning a patient's therapy with selective serotonin reuptake inhibitor (SSRI) antidepressants, the nurse will assess for concurrent use of which medications or medication class? a. Aspirin b. Anticoagulants c. Diuretics d. Nonsteroidal anti-inflammatory drugs

ANS: B Use of selective serotonin reuptake inhibitor (SSRI) antidepressants with warfarin results in an increased anticoagulant effect. SSRI antidepressants do not interact with the other drugs or drug classes listed. See Table 16-6 for important drug interactions with SSRIs.

2. A patient has been given a prescription for levodopa-carbidopa (Sinemet) for her newly diagnosed Parkinson's disease. She asks the nurse, "Why are there two drugs in this pill?" The nurse's best response reflects which fact? a. Carbidopa allows for larger doses of levodopa to be given. b. Carbidopa prevents the breakdown of levodopa in the periphery. c. There are concerns about drug-food interactions with levodopa therapy that do not exist with the combination therapy. d. Carbidopa is the biologic precursor of dopamine and can penetrate into the central nervous system.

ANS: B When given in combination with levodopa, carbidopa inhibits the breakdown of levodopa in the periphery and thus allows smaller doses of levodopa to be used. Lesser amounts of levodopa result in fewer unwanted adverse effects. Levodopa, not carbidopa, is the biologic precursor of dopamine and can penetrate into the CNS.

5. The nurse is monitoring a patient who has been taking carbamazepine (Tegretol) for 2 months. Which effects would indicate that autoinduction has started to occur? a. The drug levels for carbamazepine are higher than expected. b. The drug levels for carbamazepine are lower than expected. c. The patient is experiencing fewer seizures. d. The patient is experiencing toxic effects from the drug.

ANS: B With carbamazepine, autoinduction occurs and leads to lower than expected drug concentrations. Therefore, the dosage may have to be adjusted with time. The other options are incorrect.

2. A patient has a new prescription for phentermine (Ionamin) as part of the treatment for weight loss. Which information will the nurse include when teaching this patient about a stimulant such as phentermine? (Select all that apply.) a. Take this medication after meals. b. Take this medication in the morning. c. This drug is taken along with supervised exercise and suitable diet. d. Use mouth rinses, sugarless gum, or hard candies to minimize dry mouth. e. Avoid foods that contain caffeine, such as coffee, tea, and colas.

ANS: B, C, D, E This drug should be taken in the morning to avoid interference with sleep, and the patient should also be on a supervised exercise and dietary regime. Caffeine-containing products should be avoided because of possible additional stimulation. Dry mouth can be minimized by the use of mouth rinses, sugarless gum, or hard candy. The other option is incorrect.

1. The nurse is reviewing antiepileptic drug (AED) therapy. Which statements about AED therapy are accurate? (Select all that apply.) a. AED therapy can be stopped when seizures are stopped. b. AED therapy is usually lifelong. c. Consistent dosing is the key to controlling seizures. d. A dose may be skipped if the patient is experiencing adverse effects. e. Do not abruptly discontinue AEDs because doing so may cause rebound seizure activity.

ANS: B, C, E Patients need to know that AED therapy is usually lifelong, and compliance (with consistent dosing) is important for effective seizure control. Abruptly stopping AED therapy may cause withdrawal (or rebound) seizure activity.

1. Vicodin (acetaminophen/hydrocodone) is prescribed for a patient who has had surgery. The nurse informs the patient that which common adverse effects can occur with this medication? (Select all that apply.) a. Diarrhea b. Constipation c. Lightheadedness d. Nervousness e. Urinary retention f. Itching

ANS: B, C, E, F Constipation (not diarrhea), lightheadedness (not nervousness), urinary retention, and itching are some of the common adverse effects that the patient may experience while taking Vicodin.

1. A cholinergic drug is prescribed for a patient. The nurse checks the patient's medical history, knowing that this drug is contraindicated in which disorders? (Select all that apply.) a. Bladder atony b. Gastrointestinal obstruction c. Bradycardia d. Alzheimer's disease e. Hypotension f. Chronic obstructive pulmonary disease

ANS: B, C, E, F Contraindications to the use of cholinergic drugs include gastrointestinal or genitourinary obstruction, bradycardia, hypotension, and chronic obstructive pulmonary disease. The other options are possible indications for cholinergic drugs.

1. A nurse is providing teaching for a patient who will be taking varenicline (Chantix) as part of a smoking-cessation program. Which teaching points are appropriate for a patient taking this medication? (Select all that apply.) a. This drug is available as a chewing gum that can be taken to reduce cravings. b. Use caution when driving because drowsiness may be a problem. c. There have been very few adverse effects reported for this drug. d. Notify the prescriber immediately if feelings of sadness or thoughts of suicide occur. e. Avoid caffeine while on this drug.

ANS: B, D Patients taking varenicline have reported drowsiness, which has prompted the U.S. Food and Drug Administration (FDA) to recommend caution when driving and engaging in other potentially hazardous activities until the patient can determine how the drug affects his or her mental status. In addition, the FDA has warned about psychiatric symptoms including agitation, depression, and suicidality. Varenicline is an oral tablet, and common adverse effects include nausea, vomiting, headache, and insomnia. There are no cautions about taking caffeine while on this drug.

1. When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use of digoxin immune Fab (Digifab)? (Select all that apply.) a. The patient reports seeing colorful halos around lights. b. The patient's serum potassium level is above 5 mEq/L. c. The patient is experiencing nausea and anorexia. d. The patient is experiencing severe sinus bradycardia that does not respond to cardiac pacing. e. The patient has received an overdose of greater than 10 mg of digoxin. f. The patient reports fatigue and headaches.

ANS: B, D, E Clinical situations that would require the use of digoxin immune Fab in a patient with digoxin toxicity include serum potassium level above 5 mEq/L, severe sinus bradycardia that does not respond to cardiac pacing, or an overdose of more than 10 mg of digoxin. Seeing colorful halos around lights and experiencing nausea, anorexia, fatigue, and headaches are potential adverse effects of digoxin therapy but are not necessarily reasons for digoxin immune Fab treatment.

1. The nurse is preparing to administer a barbiturate. Which conditions or disorders would be a contraindication to the use of these drugs? (Select all that apply.) a. Gout b. Pregnancy c. Epilepsy d. Severe chronic obstructive pulmonary disease e. Severe liver disease f. Diabetes mellitus

ANS: B, D, E Contraindications to barbiturates include pregnancy, significant respiratory difficulties, and severe liver disease. The other disorders are not contraindications.

2. A patient has been taking disulfiram (Antabuse) as part of his rehabilitation therapy. However, this evening, he attended a party and drank half a beer. As a result, he became ill and his friends took him to the emergency department. The nurse will look for which adverse effects associated with acetaldehyde syndrome? (Select all that apply.) a. Euphoria b. Severe vomiting c. Diarrhea d. Pulsating headache e. Difficulty breathing f. Sweating

ANS: B, D, E, F Acetaldehyde syndrome results when alcohol is taken while on disulfiram (Antabuse) therapy. Adverse effects include CNS effects (pulsating headache, sweating, marked uneasiness, weakness, vertigo, others); GI effects (nausea, copious vomiting, thirst); and difficulty breathing. Cardiovascular effects also occur; see Table 17-2. Euphoria and diarrhea are not adverse effects associated with acetaldehyde syndrome.

2. A patient with a history of angina will be started on ranolazine (Ranexa). The nurse is reviewing the patient's history and will note potential contraindications to this drug therapy if which condition is present? (Select all that apply.) a. Type 2 diabetes mellitus b. Prolonged QT interval on the electrocardiogram c. Heart failure d. Closed-angle glaucoma e. Decreased liver function

ANS: B, E Ranolazine is contraindicated in patients with pre-existing QT prolongation or hepatic impairment. The other options are not contraindications.

6. When admitting a patient with a suspected diagnosis of chronic alcohol use, the nurse will keep in mind that chronic use of alcohol might result in which condition? a. Renal failure b. Cerebrovascular accident c. Korsakoff's psychosis d. Alzheimer's disease

ANS: C A variety of serious neurologic and mental disorders, such as Korsakoff's psychosis and Wernicke's encephalopathy, as well as cirrhosis of the liver, may occur with chronic use of alcohol. Renal failure, cerebrovascular accident, and Alzheimer's disease are not associated directly with chronic use of alcohol.

3. A patient has been diagnosed with angina and will be given a prescription for sublingual nitroglycerin tablets. When teaching the patient how to use sublingual nitroglycerin, the nurse will include which instruction? a. Take up to 5 doses at 15-minute intervals for an angina attack. b. If the tablet does not dissolve quickly, chew the tablet for maximal effect. c. If the chest pain is not relieved after one tablet, call 911 immediately. d. Wait 1 minute between doses of sublingual tablets, up to 3 doses.

ANS: C According to current guidelines, if the chest pain or discomfort is not relieved in 5 minutes, after 1 dose, the patient (or family member) must call 911 immediately. The patient may take one more tablet while awaiting emergency care and may take a third tablet 5 minutes later, but no more than a total of three tablets. The sublingual dose is placed under the tongue, and the patient needs to avoid swallowing until the tablet has dissolved.

10. A patient is to receive acetylcysteine (Mucomyst) as part of the treatment for an acetaminophen (Tylenol) overdose. Which action by the nurse is appropriate when giving this medication? a. Giving the medication undiluted for full effect b. Avoiding the use of a straw when giving this medication c. Disguising the flavor with soda or flavored water d. Preparing to give this medication via a nebulizer

ANS: C Acetylcysteine has the flavor of rotten eggs and so is better tolerated if it is diluted and disguised by mixing with a drink such as cola or flavored water to help increase its palatability. The use of a straw helps to minimize contact with the mucous membranes of the mouth and is recommended. The nebulizer form of this medication is used for certain types of pneumonia, not for acetaminophen overdose.

Pharm Ch 18 Adrenergic Drugs 1. The nurse is aware that adrenergic drugs produce effects similar to which of these nervous systems? a. Central nervous system b. Somatic nervous system c. Sympathetic nervous system d. Parasympathetic nervous system

ANS: C Adrenergic drugs mimic the effects of the sympathetic nervous system.

10. While assessing a patient who is taking a beta blocker for angina, the nurse knows to monitor for which adverse effect? a. Nervousness b. Hypertension c. Bradycardia d. Dry cough

ANS: C Adverse effects of beta blockers include bradycardia, hypotension, dizziness, lethargy, impotence, and several other effects, but not dry cough or nervousness.

13. The nurse is reviewing the food choices of a patient who is taking a monoamine oxidase inhibitor ( MAOI). Which food choice would indicate the need for additional teaching? a. Orange juice b. Fried eggs over-easy c. Salami and Swiss cheese sandwich d. Biscuits and honey

ANS: C Aged cheeses, such a Swiss or cheddar cheese, and Salami contain tyramine. Patients who are taking MAOIs need to avoid tyramine-containing foods because of a severe hypertensive reaction that may occur. Orange juice, eggs, biscuits, and honey do not contain tyramine.

6. The nurse will monitor for which adverse effect when administering an anticholinergic drug? a. Excessive urination b. Diaphoresis c. Dry mouth d. Pupillary constriction

ANS: C Anticholinergic drugs commonly cause the adverse effects of dry mouth, blurred vision, constipation, and urinary retention. They also cause mydriasis (pupillary dilation).

6. A 6-year-old child who has chickenpox also has a fever of 102.9° F (39.4° C). The child's mother asks the nurse if she should use aspirin to reduce the fever. What is the best response by the nurse? a. "It's best to wait to see if the fever gets worse." b. "You can use the aspirin, but watch for worsening symptoms." c. "Acetaminophen (Tylenol) should be used to reduce his fever, not aspirin." d. "You can use aspirin, but be sure to follow the instructions on the bottle."

ANS: C Aspirin is contraindicated in children with flu-like symptoms because the use of this drug has been strongly associated with Reye's syndrome. This is an acute and potentially life-threatening condition involving progressive neurologic deficits that can lead to coma and may also involve liver damage. Acetaminophen is appropriate for this patient. The other responses are incorrect.

6. A patient is on a low-dose dobutamine drip for heart failure. She had been feeling better but now has a sense of tightness in her chest, palpitations, and a bit of anxiety. Her heart rate is up to 110 per minute, and her blood pressure is 150/98 mm Hg (increased from previous readings of 86 per minute and 120/80 mm Hg). What is the nurse's immediate concern for this patient? a. She is experiencing normal adverse effects of dobutamine therapy. b. She may be experiencing an allergic reaction to the dobutamine. c. The medication may be causing a worsening of a pre-existing cardiac disorder. d. The dosage of the dobutamine needs to be increased to control the symptoms better.

ANS: C Because dobutamine is a vasoactive adrenergic, it works by increasing the cardiac output in heart failure patients by increasing myocardial contractility and stroke volume. However, adrenergic drugs may worsen a pre-existing cardiac disorder, such as causing a myocardial infarction in a patient with coronary artery disease. The other options are incorrect.

16. A patient is suffering from tendonitis of the knee. The nurse is reviewing the patient's medication administration record and recognizes that which adjuvant medication is most appropriate for this type of pain? a. Antidepressant b. Anticonvulsant c. Corticosteroid d. Local anesthesia

ANS: C Corticosteroids have an anti-inflammatory effect, which may help to reduce pain. The other medications do not have anti-inflammatory properties.

15. The nurse is reviewing medications used for depression. Which of these statements is a reason that selective serotonin reuptake inhibitors (SSRIs) are more widely prescribed today than tricyclic antidepressants? a. SSRIs have fewer sexual side effects. b. Unlike tricyclic antidepressants, SSRIs do not have drug-food interactions. c. Tricyclic antidepressants cause serious cardiac dysrhythmias if an overdose occurs. d. SSRIs cause a therapeutic response faster than tricyclic antidepressants.

ANS: C Death from overdose of tricyclic antidepressants usually results from either seizures or dysrhythmias. SSRIs are associated with significantly fewer and less severe systemic adverse effects, especially anticholinergic and cardiovascular adverse effects. The other options are incorrect.

8. A patient has been taking donepezil (Aricept) for 2 weeks as part of the treatment for early stages of Alzheimer's disease. Her daughter calls the prescriber's office and is upset because "Mother has not improved one bit!" Which response by the nurse is appropriate? a. "Increase the dosage to twice daily." b. "It takes time for the cure to take effect." c. "It may take up to 6 weeks to see an improvement." d. "Take the medication on an empty stomach for improved absorption."

ANS: C Donepezil therapy is not a cure for Alzheimer's disease, but it may help to improve symptoms in the early stages. It may take up to 6 weeks to see improvement. The family should be taught that the medication must be taken exactly as ordered and with meals, and the medication should not be abruptly stopped or the dosage increased without the physician's approval because of the possibility of serious complications.

11. A patient calls the clinic to speak to the nurse about taking an herbal product that contains ginkgo (Ginkgo biloba) to "help my memory." He states that he has read much information about the herbal product. Which statement by the patient indicates a need for further education? a. "I know the FDA has not approved this herbal product, but I'd like to try it to see if it helps my memory." b. "I need to watch for possible side effects, such as headaches, or stomach or intestinal upset." c. "I will take aspirin or ibuprofen (Motrin) if I have a headache." d. "Ginkgo may cause increased bleeding, so I'll have to be careful when doing yard work."

ANS: C Drug interactions may occur between the taking of aspirin and nonsteroidal anti-inflammatory drugs and the taking of ginkgo. The other options are incorrect.

12. A patient is receiving a dose of edrophonium (Tensilon). The nurse recognizes that this drug is given to determine the diagnosis of which disease? a. Parkinson's disease b. Multiple sclerosis c. Myasthenia gravis d. Alzheimer's disease

ANS: C Edrophonium, another indirect-acting cholinergic drug, is commonly used to diagnose myasthenia gravis. Edrophonium is not used in diagnosing Parkinson's disease, multiple sclerosis, or Alzheimer's disease.

4. A patient has been taking haloperidol (Haldol) for 3 months for a psychotic disorder, and the nurse is concerned about the development of extrapyramidal symptoms. The nurse will monitor the patient closely for which effects? a. Increased paranoia b. Drowsiness and dizziness c. Tremors and muscle twitching d. Dry mouth and constipation

ANS: C Extrapyramidal symptoms are manifested by tremors and muscle twitching, and the incidence of such symptoms is high during haloperidol therapy. The other options are incorrect.

12. A patient is in the intensive care unit and receiving an infusion of milrinone (Primacor) for severe heart failure. The prescriber has written an order for an intravenous dose of furosemide (Lasix). How will the nurse give this drug? a. Infuse the drug into the same intravenous line as the milrinone. b. Stop the milrinone, flush the line, and then administer the furosemide. c. Administer the furosemide in a separate intravenous line. d. Notify the prescriber that the furosemide cannot be given at this time.

ANS: C Furosemide must not be injected into an intravenous line with milrinone because it will precipitate immediately. The infusion must not be stopped because of the patient's condition. A separate line will be needed. The other options are incorrect.

5. A patient will be discharged with a 1-week supply of an opioid analgesic for pain management after abdominal surgery. The nurse will include which information in the teaching plan? a. How to prevent dehydration due to diarrhea b. The importance of taking the drug only when the pain becomes severe c. How to prevent constipation d. The importance of taking the drug on an empty stomach

ANS: C Gastrointestinal (GI) adverse effects, such as nausea, vomiting, and constipation, are the most common adverse effects associated with opioid analgesics. Physical dependence usually occurs in patients undergoing long-term treatment. Diarrhea is not an effect of opioid analgesics. Taking the dose with food may help minimize GI upset.

2. A patient is taking the nonsteroidal anti-inflammatory drug indomethacin (Indocin) as treatment for pericarditis. The nurse will teach the patient to watch for which adverse effect? a. Tachycardia b. Nervousness c. Nausea and vomiting d. Dizziness

ANS: C Gastrointestinal effects include dyspepsia, heartburn, epigastric distress, nausea, vomiting, anorexia, abdominal pain, and others. See Table 44-2 for the other adverse effects of nonsteroidal anti-inflammatory drugs (NSAIDs). The other options are not adverse effects of NSAIDs.

7. A 38-year-old man has come into the urgent care center with severe hip pain after falling from a ladder at work. He says he has taken several pain pills over the past few hours but cannot remember how many he has taken. He hands the nurse an empty bottle of acetaminophen (Tylenol). The nurse is aware that the most serious toxic effect of acute acetaminophen overdose is which condition? a. Tachycardia b. Central nervous system depression c. Hepatic necrosis d. Nephropathy

ANS: C Hepatic necrosis is the most serious acute toxic effect of an acute overdose of acetaminophen. The other options are incorrect.

4. A patient has a 9-year history of a seizure disorder that has been managed well with oral phenytoin (Dilantin) therapy. He is to be NPO (consume nothing by mouth) for surgery in the morning. What will the nurse do about his morning dose of phenytoin? a. Give the same dose intravenously. b. Give the morning dose with a small sip of water. c. Contact the prescriber for another dosage form of the medication. d. Notify the operating room that the medication has been withheld.

ANS: C If there are any questions about the medication order or the medication prescribed, contact the prescriber immediately for clarification and for an order of the appropriate dose form of the medication. Do not change the route without the prescriber's order. There is an increased risk of seizure activity if one or more doses of the AED are missed.

4. A patient who has had abdominal surgery has been discharged on a cholinergic drug to assist in increasing gastrointestinal peristalsis. The nurse will teach this patient to look for which therapeutic effect? a. Decreased pulse rate b. Abdominal cramping c. Passage of flatus d. Decreased urge to void

ANS: C In patients suffering a decrease in GI peristalsis postoperatively, taking a cholinergic drug should result in an increase in bowel sounds, the passage of flatus, and the occurrence of bowel movements that indicate increased GI peristalsis.

6. A factory worker has been admitted to the emergency department after an industrial accident involving organophosphate insecticides. The nurse will prepare to administer which drug? a. Pilocarpine (Salagen) b. Bethanechol (Urecholine) c. Physostigmine (Antilirium) d. Tacrine (Cognex)

ANS: C Indirect-acting drugs such as physostigmine inhibit acetylcholinesterase, thus reversing the neuromuscular blockade produced by anticholinergic poisoning as well as poisoning by irreversible cholinesterase inhibitors such as the organophosphates and carbamates, common classes of insecticides. The other drugs listed are not appropriate antidotes.

14. The nurse is assessing a patient for contraindications to drug therapy with acetaminophen (Tylenol). Which patient should not receive acetaminophen? a. A patient with a fever of 101° F (38.3° C) b. A patient who is complaining of a mild headache c. A patient with a history of liver disease d. A patient with a history of peptic ulcer disease

ANS: C Liver disease is a contraindication to the use of acetaminophen. Fever and mild headache are both possible indications for the medication. Having a history of peptic ulcer disease is not a contraindication.

Pharm Ch 44 Antiinflammatory and Antigout Drugs 1. The nurse is reviewing the therapeutic effects of nonsteroidal anti-inflammatory drugs (NSAIDs), which include which effect? a. Anxiolytic b. Sedative c. Antipyretic d. Antimicrobial

ANS: C NSAIDs have antipyretic effects but not the other effects listed.

4. A 78-year-old patient is in the recovery room after having a lengthy surgery on his hip. As he is gradually awakening, he requests pain medication. Within 10 minutes after receiving a dose of morphine sulfate, he is very lethargic and his respirations are shallow, with a rate of 7 per minute. The nurse prepares for which priority action at this time? a. Assessment of the patient's pain level b. Immediate intubation and artificial ventilation c. Administration of naloxone (Narcan) d. Close observation of signs of opioid tolerance

ANS: C Naloxone, an opioid-reversal agent, is used to reverse the effects of acute opioid overdose and is the drug of choice for reversal of opioid-induced respiratory depression. This situation is describing an opioid overdose, not opioid tolerance. Intubation and artificial ventilation are not appropriate because the patient is still breathing at 7 breaths/min. It would be inappropriate to assess the patient's level of pain.

6. When evaluating a patient who is taking orlistat (Xenical), which is an intended therapeutic effect? a. Increased wakefulness b. Increased appetite c. Decreased weight d. Decreased hyperactivity

ANS: C Orlistat (Xenical) is a nonstimulant drug that is used as part of a weight loss program. The other options are incorrect.

9. The nurse administering the phosphodiesterase inhibitor milrinone (Primacor) recognizes that this drug will have a positive inotropic effect. Which result reflects this effect? a. Increased heart rate b. Increased blood vessel dilation c. Increased force of cardiac contractions d. Increased conduction of electrical impulses across the heart

ANS: C Positive inotropic drugs increase myocardial contractility, thus increasing the force of cardiac conduction. Positive chronotropic drugs increase the heart rate. Positive dromotropic drugs increase the conduction of electrical impulses across the heart. Blood vessel dilation is not affected.

8. Ramelteon (Rozerem) is prescribed for a patient with insomnia. The nurse checks the patient's medical history, knowing that this medication is contraindicated in which disorder? a. Coronary artery disease b. Renal insufficiency c. Liver disease d. Anemia

ANS: C Ramelteon is contraindicated in cases of severe liver dysfunction. The other conditions are not contraindications.

9. The nurse recognizes that adrenergic drugs cause relaxation of the bronchi and bronchodilation by stimulating which type of receptors? a. Dopaminergic b. Beta1 adrenergic c. Beta2 adrenergic d. Alpha1 adrenergic

ANS: C Stimulation of beta2-adrenergic receptors results in bronchodilation. The other choices are incorrect.

5. A cholinergic drug is prescribed for a patient with a new diagnosis of myasthenia gravis, and the nurse provides instructions to the patient about the medication. What is important to include in the teaching? a. Take the medication with meals to avoid gastrointestinal distress. b. Give daytime doses close together for maximal therapeutic effect. c. Take the medication 30 minutes before eating to improve swallowing and chewing. d. Take the medication only if difficulty swallowing occurs during a meal.

ANS: C Taking the medication 30 minutes before meals allows time for the onset of action and therapeutic effects during the meal. The doses should be spaced evenly apart to optimize the effects of the medication. The other options are incorrect.

5. A 29-year-old male patient is admitted to the intensive care unit with the following symptoms: restlessness, hyperactive reflexes, talkativeness, confusion and periods of panic and euphoria, tachycardia, and fever. The nurse suspects that he may be experiencing the effects of taking which substance? a. Opioids b. Alcohol c. Stimulants d. Depressants

ANS: C The adverse effects listed may occur with use of stimulants and are commonly an extension of their therapeutic effects. Opioids, alcohol, and depressants do not have these effects.

4. A 22-year-old nursing student has been taking NoDoz (caffeine) tablets for the past few weeks to "make it through" the end of the semester and exam week. She is in the university clinic today because she is "exhausted." What nursing diagnosis may be appropriate for her? a. Noncompliance b. Impaired physical mobility c. Disturbed sleep pattern d. Imbalanced nutrition: less than body requirements

ANS: C The main ingredient in NoDoz, caffeine, is a central nervous system stimulant that can be used to increase mental alertness. Restlessness, anxiety, and insomnia are common adverse effects. Thus, disturbed sleep pattern is the most appropriate nursing diagnosis of those listed.

12. The nurse is assessing a patient who has been admitted to the emergency department for a possible opioid overdose. Which assessment finding is characteristic of an opioid drug overdose? a. Dilated pupils b. Restlessness c. Respiration rate of 6 breaths/min d. Heart rate of 55 beats/min

ANS: C The most serious adverse effect of opioid use is CNS depression, which may lead to respiratory depression. Pinpoint pupils, not dilated pupils, are seen. Restlessness and a heart rate of 55 beats/min are not indications of an opioid overdose.

Pharm Ch 23 Antianginal Drugs 1. When the nurse is administering topical nitroglycerin ointment, which technique is correct? a. Apply the ointment on the skin on the forearm. b. Apply the ointment only in the case of a mild angina episode. c. Remove the old ointment before new ointment is applied. d. Massage the ointment gently into the skin, and then cover the area with plastic wrap.

ANS: C The old ointment should be removed before a new dose is applied. The ointment should be applied to clean, dry, hairless skin of the upper arms or body, not below the elbows or below the knees. The ointment is not massaged or spread on the skin, and it is not indicated for the treatment of acute angina.

11. When treating patients with medications for Parkinson's disease, the nurse knows that the wearing-off phenomenon occurs for which reason? a. There are rapid swings in the patient's response to levodopa. b. The patient cannot tolerate the medications at times. c. The medications begin to lose effectiveness against Parkinson's disease. d. The patient's liver is no longer able to metabolize the drug.

ANS: C The wearing-off phenomenon occurs when antiparkinson medications begin to lose their effectiveness, despite maximal dosing, as the disease progresses. The other options are incorrect.

7. A patient is brought to the emergency department for treatment of a suspected overdose. The patient was found with an empty prescription bottle of a barbiturate by his bedside. He is lethargic and barely breathing. The nurse would expect which immediate intervention? a. Starting an intravenous infusion of diluted bicarbonate solution b. Administering medications to increase blood pressure c. Implementing measures to maintain the airway and support respirations d. Administrating naloxone (Narcan) as an antagonist

ANS: C There are no antagonists/antidotes for barbiturates. Treatment supports respirations and maintains the airway. The other interventions are not appropriate.

5. The teaching for a patient who is taking tamsulosin (Flomax) to reduce urinary obstruction due to benign prostatic hyperplasia will include which of these? a. Fluids need to be restricted while on this medication. b. Take the medication with breakfast to promote the maximum effects of the drug. c. Get up slowly from a sitting or lying position. d. Blood pressure must be monitored because the medication may cause hypertension.

ANS: C This medication is used to relieve impaired urinary flow in men with benign prostatic hyperplasia, but it also can cause orthostatic hypotension when changing positions from sitting or lying positions. Because of these effects, the blood pressure may become dramatically lowered, and lightheadedness may occur, increasing the risk of falling.

6. The nurse is assessing the medication history of a patient with a new diagnosis of Parkinson's disease. Which condition is a contraindication for the patient, who will be taking tolcapone (Tasmar)? a. Glaucoma b. Seizure disorder c. Liver failure d. Benign prostatic hyperplasia

ANS: C Tolcapone is contraindicated in patients who have shown a hypersensitivity reaction to it, and it should be used with caution in patients with pre-existing liver disease. The other conditions listed are not contraindications.

7. The nurse is reviewing a patient's medication history and notes that the patient is taking the cholinergic blocker tolterodine (Detrol). Which is an indication for this medication? a. Irritable bowel disease b. Induction of mydriasis c. Urge incontinence d. Reduction of secretions preoperatively

ANS: C Tolterodine (Detrol) is used for urinary frequency, urgency, and urge incontinence caused by bladder (detrusor) overactivity. The conditions in the other options are not indications.

11. When teaching a patient who has a new prescription for transdermal nitroglycerin patches, the nurse tells the patient that these patches are most appropriately used for which situation? a. To prevent low blood pressure b. To relieve shortness of breath c. To prevent the occurrence of angina d. To keep the heart rate from rising too high during exercise

ANS: C Transdermal dosage formulations of nitroglycerin are used for the long-term prophylactic management (prevention) of angina pectoris. Transdermal nitroglycerin patches are not appropriate for the relief of shortness of breath, to prevent palpitations, or to control the heart rate during exercise.

5. The nurse is administering a stat dose of epinephrine. Epinephrine is appropriate for which situation? a. Severe hypertension b. Angina c. Cardiac arrest d. Tachycardia

ANS: C Treatment of cardiac arrest is an indication for the use of epinephrine. The other options are not indications for epinephrine.

10. A patient has been admitted to the emergency department with a suspected overdose of a tricyclic antidepressant. The nurse will prepare for what immediate concern? a. Hypertension b. Renal failure c. Cardiac dysrhythmias d. Gastrointestinal bleeding

ANS: C Tricyclic antidepressant overdoses are notoriously lethal. The primary organ systems affected are the central nervous system and the cardiovascular system, and death usually results from either seizures or dysrhythmias.

4. A patient has been taking temazepam (Restoril) for intermittent insomnia. She calls the nurse to say that when she takes it, she sleeps well, but the next day she feels "so tired." Which explanation by the nurse is correct? a. "Long-term use of this drug results in a sedative effect." b. "If you take the drug every night, this hangover effect will be reduced." c. "These drugs affect the sleep cycle, resulting in daytime sleepiness." d. "These drugs increase the activity of the central nervous system, making you tired the next day."

ANS: C Benzodiazepines suppress REM sleep to a degree (although not as much as barbiturates) and, thus, result in daytime sleepiness (a hangover effect). The other statements are incorrect.

2. Which statements are true regarding the selective serotonin reuptake inhibitors (SSRIs)? (Select all that apply.) a. Avoid foods and beverages that contain tyramine. b. Monitor the patient for extrapyramidal symptoms. c. Therapeutic effects may not be seen for about 4 to 6 weeks after the medication is started. d. If the patient has been on an MAOI, a 2- to 5-week or longer time span is required before beginning an SSRI medication. e. These drugs have anticholinergic effects, including constipation, urinary retention, dry mouth, and blurred vision. f. Cogentin is often also prescribed to reduce the adverse effects that may occur.

ANS: C, D During SSRI medication, therapeutic effects may not be seen for 4 to 6 weeks. To prevent the potentially fatal pharmacodynamic interactions that can occur between the SSRIs and the MAOIs, a 2- to 5-week washout period is recommended between uses of these two classes of medications. The other options apply to other classes of psychotherapeutic drugs, not SSRIs.

2. A 75-year-old woman has been given a nonsteroidal anti-inflammatory drug (an NSAID for the treatment of rheumatoid arthritis. The nurse is reviewing the patient's medication history and notes that which types of medications could have an interaction with the NSAID? (Select all that apply.) a. Antibiotics b. Decongestants c. Anticoagulants d. Beta blockers e. Diuretics f. Corticosteroids

ANS: C, E, F Anticoagulants taken with NSAIDs may cause increased bleeding tendencies because of platelet inhibition and hypoprothrombinemia. NSAIDs taken with diuretics may cause reduced hypotensive and diuretic effects. NSAIDs taken with corticosteroids may cause increased ulcerogenic effects. See Table 44-5. The other options are incorrect.

9. What action is often recommended to help reduce tolerance to transdermal nitroglycerin therapy? a. Omit a dose once a week. b. Leave the patch on for 2 days at a time. c. Cut the patch in half for 1 week until the tolerance subsides. d. Remove the patch at bedtime, and then apply a new one in the morning.

ANS: D To prevent tolerance, remove the transdermal patch at night for 8 hours, and apply a new patch in the morning. Transdermal patches must never be cut or left on for 2 days, and doses must not be omitted.

15. A patient arrives at the urgent care center complaining of leg pain after a fall when rock climbing. The x-rays show no broken bones, but he has a large bruise on his thigh. The patient says he drives a truck and does not want to take anything strong because he needs to stay awake. Which statement by the nurse is most appropriate? a. "It would be best for you not to take anything if you are planning to drive your truck." b. "We will discuss with your doctor about taking an opioid because that would work best for your pain." c. "You can take acetaminophen, also known as Tylenol, for pain, but no more than 1000 mg per day." d. "You can take acetaminophen, also known as Tylenol, for pain, but no more than 3000 mg per day."

ANS: D Acetaminophen is indicated for mild-to-moderate pain and does not cause drowsiness, as an opioid would. Currently, the maximum daily amount of acetaminophen is 3000 mg/day. The 1000-mg amount per day is too low. Telling the patient not to take any pain medications is incorrect.

9. The nurse working in a preoperative admitting unit administers an anticholinergic medication to a patient before surgery. What is the purpose of this drug in the preoperative setting? a. Control the heart rate b. Relax the patient c. Reduce urinary frequency d. Reduce oral and gastrointestinal secretions

ANS: D Anticholinergic drugs are given preoperatively to control oral and gastrointestinal secretions during surgery. The other options are incorrect.

3. The nurse is reviewing the use of anticholinergic drugs. Anticholinergic drugs block the effects of which nervous system? a. Central nervous system b. Somatic nervous system c. Sympathetic nervous system d. Parasympathetic nervous system

ANS: D Anticholinergic drugs block or inhibit the actions of acetylcholine in the parasympathetic nervous system. The other options are incorrect.

8. A patient who has a history of coronary artery disease has been instructed to take one 81-mg aspirin tablet a day. The patient asks about the purpose of this aspirin. Which response by the nurse is correct? a. "Aspirin is given reduce anxiety." b. "It helps to reduce inflammation." c. "Aspirin is given to relieve pain." d. "It will help to prevent clot formation."

ANS: D Aspirin can reduce platelet aggregation; low doses of aspirin (81 to 325 mg once daily) are used for thromboprevention. Higher doses are required for pain relief, reduction of inflammation, and reduction of fever. The other options are incorrect.

2. A patient has been taking phenobarbital for 2 weeks as part of his therapy for epilepsy. He tells the nurse that he feels tense and that "the least little thing" bothers him now. Which is the correct explanation for this problem? a. These are adverse effects that usually subside after a few weeks. b. The drug must be stopped immediately because of possible adverse effects. c. This drug causes the rapid eye movement (REM) sleep period to increase, resulting in nightmares and restlessness. d. This drug causes deprivation of REM sleep and may cause the inability to deal with normal stress.

ANS: D Barbiturates such as phenobarbital deprive people of REM sleep, which can result in agitation and the inability to deal with normal stress. A rebound phenomenon occurs when the drug is stopped (not during therapy), and the proportion of REM sleep increases, sometimes resulting in nightmares. The other options are incorrect.

4. A 58-year-old man has had a myocardial infarction (MI), has begun rehabilitation, and is ready for discharge. He is given a prescription for metoprolol (Lopressor) and becomes upset after reading the patient education pamphlet. "I don't have high blood pressure—why did my doctor give me this medicine?" Which explanation by the nurse is correct? a. "This medication will prevent blood clots that may lead to another heart attack." b. "Beta blockers will improve blood flow to the kidneys." c. "This drug is prescribed to prevent the high blood pressure that often occurs after a heart attack." d. "Studies have shown that this medication has greatly increased survival rates in patients who have had a heart attack."

ANS: D Beta blockers are frequently given to patients after they have suffered an MI because of their cardioprotective properties. The other responses are incorrect.

8. A patient has been taking a beta blocker for 4 weeks as part of his antianginal therapy. He also has type II diabetes and hyperthyroidism. When discussing possible adverse effects, the nurse will include which information? a. "Watch for unusual weight loss." b. "Monitor your pulse for increased heart rate." c. "Use the hot tub and sauna at the gym as long as time is limited to 15 minutes." d. "Monitor your blood glucose levels for possible hypoglycemia or hyperglycemia."

ANS: D Beta blockers can cause both hypoglycemia and hyperglycemia. They may also cause weight gain if heart failure is developing, and decreased pulse rate. The use of hot tubs and saunas is not recommended because of the possibility of hypotensive episodes.

7. The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin? a. Leafy green vegetables b. Dairy products c. Grapefruit juice d. Bran muffins

ANS: D Bran, in large amounts, may decrease the absorption of oral digitalis drugs. The other foods do not affect digoxin levels.

8. A patient has a new order for a catechol ortho-methyltransferase (COMT) inhibitor as part of treatment for Parkinson's disease. The nurse recognizes that which of these is an advantage of this drug class? a. It has a shorter duration of action. b. It causes less gastrointestinal distress. c. It has a slower onset than traditional Parkinson's disease drugs. d. It is associated with fewer wearing-off effects.

ANS: D COMT inhibitors are associated with fewer wearing-off effects and have prolonged therapeutic benefits. They have a quicker onset, and they prolong the duration of action of levodopa.

3. A 6-year-old boy has been started on an extended-release form of methylphenidate hydrochloride (Ritalin) for the treatment of attention deficit hyperactivity disorder (ADHD). During a follow-up visit, his mother tells the nurse that she has been giving the medication at bedtime so that it will be "in his system" when he goes to school the next morning. What is the nurse's appropriate evaluation of the mother's actions? a. She is giving him the medication dosage appropriately. b. The medication should not be taken until he is at school. c. The medication should be taken with meals for optimal absorption. d. The medication should be given 4 to 6 hours before bedtime to diminish insomnia.

ANS: D Central nervous system stimulants should be taken 4 to 6 hours before bedtime to decrease insomnia. Generally speaking, once-a-day dosing is used with extended-release or long-acting preparations. These formulations eliminate the need to take this medication at school.

4. The nurse is teaching a patient who is taking colchicine for the treatment of gout. Which instruction will the nurse include during the teaching session? a. "Fluids should be restricted while on colchicine therapy." b. "Take colchicine with meals." c. "The drug will be discontinued when symptoms are reduced." d. "Call your doctor if you have increased pain or blood in the urine."

ANS: D Colchicine may cause renal effects; therefore, these symptoms must be reported immediately. The drug is taken on an empty stomach for better absorption, and fluids should be increased unless contraindicated. Successful treatment depends upon continuing the medication as ordered.

5. Carbidopa-levodopa (Sinemet) is prescribed for a patient with Parkinson's disease. The nurse informs the patient that which common adverse effects can occur with this medication? a. Drowsiness, headache, weight loss b. Dizziness, insomnia, nausea c. Peripheral edema, fatigue, syncope d. Heart palpitations, hypotension, urinary retention

ANS: D Common adverse reactions associated with carbidopa-levodopa include palpitations, hypotension, urinary retention, dyskinesia, and depression. The other effects may occur with other antiparkinson drugs.

3. When teaching a patient about taking a newly prescribed antiepileptic drug (AED) at home, the nurse will include which instruction? a. "Driving is allowed after 2 weeks of therapy." b. "If seizures recur, take a double dose of the medication." c. "Antacids can be taken with the AED to reduce gastrointestinal adverse effects." d. "Regular, consistent dosing is important for successful treatment."

ANS: D Consistent dosing, taken regularly at the same time of day, at the recommended dose, and with meals to reduce the common gastrointestinal adverse effects, is the key to successful management of seizures when taking AEDs. Noncompliance is the factor most likely to lead to treatment failure.

6. A calcium channel blocker (CCB) is prescribed for a patient, and the nurse provides instructions to the patient about the medication. Which instruction is correct? a. Chew the tablet for faster release of the medication. b. To increase the effect of the drug, take it with grapefruit juice. c. If the adverse effects of chest pain, fainting, or dyspnea occur, discontinue the medication immediately. d. A high-fiber diet with plenty of fluids will help prevent the constipation that may occur.

ANS: D Constipation is a common effect of CCBs, and a high-fiber diet and plenty of fluids will help to prevent it. Grapefruit juice decreases the metabolism of CCBs. Extended-release tablets must never be chewed or crushed. These medications should never be discontinued abruptly because of the risk for rebound hypertension.

2. A patient has a prescription for oxybutynin (Ditropan), an anticholinergic drug. When reviewing the patient's medical history, which condition, if present, would be considered a contraindication to therapy with this drug? a. Diarrhea b. Hypertension c. Neurogenic bladder d. Uncontrolled angle-closure glaucoma

ANS: D Contraindications include drug allergy, urinary or gastric retention, and uncontrolled angle-closure glaucoma. Neurogenic bladder is an indication for oxybutynin. The other options are incorrect.

7. A patient has used enteric aspirin for several years as treatment for osteoarthritis. However, the symptoms are now worse and she is given a prescription for a nonsteroidal anti-inflammatory drug and misoprostol (Cytotec). The patient asks the nurse, "Why am I now taking two pills for arthritis?" What is the nurse's best response? a. "Cytotec will also reduce the symptoms of your arthritis." b. "Cytotec helps the action of the NSAID so that it will work better." c. "Cytotec reduces the mucous secretions in the stomach, which reduces gastric irritation." d. "Cytotec may help to prevent gastric ulcers that may occur in patients taking NSAIDs."

ANS: D Cytotec inhibits gastric acid secretions and stimulates mucous secretions; it has proved successful in preventing the gastric ulcers that may occur in patients taking NSAIDs.

Pharm Ch 24 Heart Failure Drugs 1. A patient about to receive a morning dose of digoxin has an apical pulse of 53 beats/min. What will the nurse do next? a. Administer the dose. b. Administer the dose, and notify the prescriber. c. Check the radial pulse for 1 full minute. d. Withhold the dose, and notify the prescriber.

ANS: D Digoxin doses are held and the prescriber notified if the apical pulse is 60 beats/min or lower or is higher than 100 beats/min. The other options are incorrect.

4. A patient has been taking digoxin at home but took an accidental overdose and has developed toxicity. The patient has been admitted to the telemetry unit, where the physician has ordered digoxin immune Fab (Digifab). The patient asks the nurse why the medication is ordered. What is the nurse's best response? a. "It will increase your heart rate." b. "This drug helps to lower your potassium levels." c. "It helps to convert the irregular heart rhythm to a more normal rhythm." d. "This drug is an antidote to digoxin and will help to lower the blood levels."

ANS: D Digoxin immune Fab (Digifab) is the antidote for a severe digoxin overdose. It is given intravenously. The other options are incorrect.

7. The nurse is providing teaching regarding drug therapy to the husband of a woman with Alzheimer's disease. She was diagnosed 3 months ago, has mild memory loss, and will be receiving donepezil (Aricept). What is the drug's expected action? a. Prevents memory loss in later stages b. Reverses the course of Alzheimer's disease c. Provides sedation to prevent agitation and restlessness d. May help to improve the mood and decrease confusion

ANS: D Donepezil is used to treat mild-to-moderate dementia occurring in Alzheimer's disease and may improve the symptoms of the disease.

10. The nurse is preparing to administer dopamine. Which is the correct technique for administering dopamine? a. Orally b. Intravenous (IV) push injection c. Intermittent IV infusions (IV piggyback) d. Continuous IV infusion with an infusion pump

ANS: D Dopamine is available only as an IV injectable drug and is given by continuous infusion, using an infusion pump. The other options are incorrect.

3. When a patient is taking an anticholinergic such as benztropine (Cogentin) as part of the treatment for Parkinson's disease, the nurse should include which information in the teaching plan? a. Minimize the amount of fluid taken while on this drug. b. Discontinue the medication if adverse effects occur. c. Take the medication on an empty stomach to enhance absorption. d. Use artificial saliva, sugarless gum, or hard candy to counteract dry mouth.

ANS: D Dry mouth can be managed with artificial saliva through drops or gum, frequent mouth care, forced fluids, and sucking on sugar-free hard candy. Anticholinergics should be taken with or after meals to minimize GI upset and must not be discontinued suddenly. The patient must drink at least 3000 mL/day unless contraindicated. Drinking water is important, even if the patient is not thirsty or in need of hydration, to prevent and manage the adverse effect of constipation.

5. A 72-year-old man has a new prescription for an anticholinergic drug. He is an active man and enjoys outdoor activities, such as golfing and doing his own yard work. What will the nurse emphasize to him during the teaching session about his drug therapy? a. Drowsiness may interfere with his outdoor activities. b. Increased salivation may occur during exercise and outside activities. c. Fluid volume deficits may occur as a result of an increased incidence of diarrhea. d. He will need to take measures to reduce the occurrence of heat stroke during his activities.

ANS: D Elderly patients who take an anticholinergic drug need to be reminded that they are at a greater risk for suffering heat stroke because of decreased sweating and loss of normal heat-regulating mechanisms.

10. A patient has experienced insomnia for months, and the physician has prescribed a medication to help with this problem. The nurse expects which drug to be used for long-term treatment of insomnia? a. Secobarbital (Seconal), a barbiturate b. Diazepam (Valium), a benzodiazepine c. Midazolam (Versed), a benzodiazepine d. Eszopiclone (Lunesta), a nonbenzodiazepine sleep aid

ANS: D Eszopiclone (Lunesta) is one of the newest prescription hypnotics to be approved for long-term use in treatment of insomnia. Barbiturates and benzodiazepines are not appropriate for long-term treatment of insomnia; midazolam is used for procedural (moderate) sedation.

5. A patient has been taking the monoamine oxidase inhibitor (MAOI) phenelzine (Nardil) for 6 months. The patient wants to go to a party and asks the nurse, "Will just one beer be a problem?" Which advice from the nurse is correct? a. "You can drink beer as long as you have a designated driver." b. "Now that you've had the last dose of that medication, there will be no further dietary restrictions." c. "If you begin to experience a throbbing headache, rapid pulse, or nausea, you'll need to stop drinking." d. "You need to avoid all foods that contain tyramine, including beer, while taking this medication."

ANS: D Foods containing tyramine, such as beer and aged cheeses, should be avoided while a patient is taking an MAOI. Drinking beer while taking an MAOI may precipitate a dangerous hypertensive crisis. The other options are incorrect.

9. A 49-year-old patient is in the clinic for a follow-up visit 6 months after starting a beta blocker for treatment of hypertension. During this visit, his blood pressure is 169/98 mm Hg, and he eventually confesses that he stopped taking this medicine 2 months ago because of an "embarrassing problem." What problem did the patient most likely experience with this medication that caused him to stop taking it? a. Urge incontinence b. Dizziness when standing up c. Excessive flatus d. Impotence

ANS: D Impotence is a potential adverse effect of beta blockers and may cause patients to stop taking the medication. The other options are not adverse effects of beta blockers.

3. A patient has been taking naltrexone (ReVia) as part of the treatment for addiction to heroin. The nurse expects that the naltrexone will have which therapeutic effect for this patient? a. Naltrexone prevents the cravings for opioid drugs. b. Naltrexone works as a safer substitute for the heroin until the patient completes withdrawal. c. The patient will experience flushing, sweating, and severe nausea if he takes heroin while on naltrexone. d. If opioid drugs are used while taking naltrexone, euphoria is not produced; thus, the opioid's desired effects are lost.

ANS: D Naltrexone works to eliminate the euphoria that occurs with opioid drug use; therefore, the reinforcing effect of the drug is lost.

13. The drug nalbuphine (Nubain) is an agonist-antagonist (partial agonist). The nurse understands that which is a characteristic of partial agonists? a. They have anti-inflammatory effects. b. They are given to reverse the effects of opiates. c. They have a higher potency than agonists. d. They have a lower dependency potential than agonists.

ANS: D Partial agonists such as nalbuphine are similar to the opioid agonists in terms of their therapeutic indications; however, they have a lower risk of misuse and addiction. They do not have anti-inflammatory effects, nor are they given to reverse the effects of opiates. They do not have a higher potency than agonists.

11. A patient tells the nurse that he likes to drink kava herbal tea to help him relax. Which statement by the patient indicates that additional teaching about this herbal product is needed? a. "I will not drink wine with the kava tea." b. "If I notice my skin turning yellow, I will stop taking the tea." c. "I will not take sleeping pills if I have this tea in the evening." d. "I will be able to drive my car after drinking this tea."

ANS: D Patients should not drive after drinking this tea because it may cause sedation. Kava tea may cause skin discoloration (with long-term use). In addition, it must not be taken with alcohol, barbiturates, and psychoactive drugs.

7. A patient with the diagnosis of schizophrenia is hospitalized and is taking a phenothiazine drug. Which statement by this patient indicates that he is experiencing a common adverse effect of phenothiazines? a. "I can't sleep at night." b. "I feel hungry all the time." c. "Look at how red my hands are." d. "My mouth has been so dry lately."

ANS: D Phenothiazines produce anticholinergic-like adverse effects of dry mouth, urinary hesitancy, and constipation.

3. During initial rounds, the nurse notes that a dobutamine infusion has extravasated into the forearm of a patient. After stopping the infusion, the nurse follows standing orders and immediately injects phentolamine (Regitine) subcutaneously in a circular fashion around the extravasation site. What is the mechanism of action of the phentolamine in this situation? a. It neutralizes the extravasated dobutamine immediately. b. It causes arterial vasoconstriction and reduced pain and swelling at the site. c. It increases peripheral vascular resistance and reduces arterial pressure at the site. d. It increases blood flow to the ischemic site by vasodilation to prevent tissue damage.

ANS: D Phentolamine is an alpha blocker that reduces peripheral vascular resistance when given systemically, but local subcutaneous injection around the site of extravasated vasoconstrictive drugs, such as dobutamine, causes an alpha-adrenergic receptor blockade and vasodilation. This allows for increased blood flow to the ischemic tissue and may prevent permanent tissue damage.

4. A patient has received an accidental overdose of intravenous atropine. Which drug will the nurse prepare to administer? a. Atenolol (Tenormin) b. Bethanechol (Urecholine) c. Dicyclomine (Bentyl) d. Physostigmine (Antilirium)

ANS: D Physostigmine salicylate is the antidote to an atropine overdose in patients who show extreme delirium or agitation and could inflict injury to themselves. Its routine use as an antidote for cholinergic-blocker overdose is controversial, however. The other options are incorrect choices.

3. A patient has had an overdose of an intravenous cholinergic drug. The nurse expects to administer which drug as an antidote? a. Atenolol (Tenormin) b. Bethanechol (Urecholine) c. Dobutamine d. Atropine sulfate

ANS: D Prompt administration of atropine sulfate can reverse a toxic dose of cholinergic drugs. The other drugs listed are not antidotes to cholinergic toxicity.

2. A patient who started taking orlistat (Xenical) 1 month ago calls the clinic to report some "embarrassing" adverse effects. She tells the nurse that she has had episodes of "not being able to control my bowel movements." Which statement is true about this situation? a. These are expected adverse effects that will eventually diminish. b. The patient will need to stop this drug immediately if these adverse effects are occurring. c. The patient will need to increase her fat intake to prevent these adverse effects. d. The patient will need to restrict fat intake to less than 30% to help reduce these adverse effects.

ANS: D Restricting dietary intake of fat to less than 30% of total calories can help reduce some of the GI adverse effects, which include oily spotting, flatulence, and fecal incontinence. The other options are incorrect.

7. A 14-year-old patient has been treated for asthma for almost 4 months. Two weeks ago, she was given salmeterol as part of her medication regimen. However, her mother has called the clinic to report that it does not seem to work when her daughter is having an asthma attack. Which response by the nurse is appropriate? a. "It takes time for a therapeutic response to develop." b. "She is too young for this particular medication; it will be changed." c. "She needs to take up to two puffs every 4 hours to ensure adequate blood levels." d. "This medication is indicated for prevention of bronchospasms, not for relief of acute symptoms."

ANS: D Salmeterol is indicated for the prevention of bronchospasms, not treatment of acute symptoms. The dosage is usually two puffs twice daily, 12 hours apart, for maintenance effects in patients older than 12 years of age. The other options are incorrect.

2. An 18-year-old basketball player fell and twisted his ankle during a game. The nurse will expect to administer which type of analgesic? a. Synthetic opioid, such as meperidine (Demerol) b. Opium alkaloid, such as morphine sulfate c. Opioid antagonist, such as naloxone HCL (Narcan) d. Nonopioid analgesic, such as indomethacin (Indocin)

ANS: D Somatic pain, which originates from skeletal muscles, ligaments, and joints, usually responds to nonopioid analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs). The other options are not the best choices for somatic pain.

8. A patient has been taking the selective serotonin reuptake inhibitor (SSRI) sertraline (Zoloft) for about 6 months. At a recent visit, she tells the nurse that she has been interested in herbal therapies and wants to start taking St. John's wort. Which response by the nurse is appropriate? a. "That should be no problem." b. "Good idea! Hopefully you'll be able to stop taking the Zoloft." c. "Be sure to stop taking the herb if you notice a change in side effects." d. "Taking St. John's wort with Zoloft may cause severe interactions and is not recommended."

ANS: D The herbal product St. John's wort must not be used with SSRIs. Potential interactions include confusion, agitation, muscle spasms, twitching, and tremors. The other responses by the nurse are inappropriate.

8. A patient has been taking tolterodine (Detrol), but today her prescriber changed her to a newer drug, darifenacin (Enablex). What advantage does darifenacin have over the tolterodine? a. The newer cholinergic-blocker drugs are more effective. b. It helps reduce urinary retention. c. It can be used in patients with narrow-angle glaucoma. d. The incidence of dry mouth is much lower with darifenacin.

ANS: D The incidence of dry mouth is much lower with use of the newer cholinergic-blocker drugs, such as darifenacin, because the actions of these drugs are more specific for the bladder as opposed to the salivary glands. These drugs are contraindicated if narrow-angle glaucoma or urinary retention is present. The newer cholinergic-blocker drugs are not necessarily more effective.

5. A mother brings her toddler into the emergency department and tells the nurse that she thinks the toddler has eaten an entire bottle of chewable aspirin tablets. The nurse will assess for which most common signs of salicylate intoxication in children? a. Photosensitivity and nervousness b. Tinnitus and hearing loss c. Acute gastrointestinal bleeding d. Hyperventilation and drowsiness

ANS: D The most common manifestations of chronic salicylate intoxication in adults are tinnitus and hearing loss. Those in children are hyperventilation and CNS effects, such as dizziness, drowsiness, and behavioral changes.

2. The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication? a. The solution will be slightly colored green or blue. b. The intravenous form is given by bolus injection. c. It can be given in infusions with other medications. d. Non-polyvinylchloride (non-PVC) plastic intravenous bags and tubing must be used.

ANS: D The non-PVC infusion kits are used to avoid absorption and/or uptake of the nitrate by the intravenous tubing and bag and/or decomposition of the nitrate. The medication is given by infusion via an infusion pump and not with other medications. It is not given by bolus injection. If the parenteral solution is discolored blue or green, it should be discarded.

5. A patient has been placed on a milrinone (Primacor) infusion as part of the therapy for end-stage heart failure. What adverse effect of this drug will the nurse watch for when assessing this patient during the infusion? a. Hypertension b. Hyperkalemia c. Nausea and vomiting d. Cardiac dysrhythmias

ANS: D The primary adverse effects seen with milrinone are cardiac dysrhythmias, mainly ventricular. It may also cause hypotension, hypokalemia, and other effects, but not nausea and vomiting.

11. During a routine appointment, a patient with a history of seizures is found to have a phenytoin (Dilantin) level of 23 mcg/mL. What concern will the nurse have, if any? a. The patient is at risk for seizures because the drug level is not at a therapeutic level. b. The patient's seizures should be under control because this is a therapeutic drug level. c. The patient's seizures should be under control if she is also taking a second antiepileptic drug. d. The drug level is at a toxic level, and the dosage needs to be reduced.

ANS: D Therapeutic drug levels for phenytoin are usually 10 to 20 mcg/mL (see Table 14-6). The other options are incorrect.

4. A patient has been treated with antiparkinson medications for 3 months. What therapeutic responses should the nurse look for when assessing this patient? a. Decreased appetite b. Gradual development of cogwheel rigidity c. Newly developed dyskinesias d. Improved ability to perform activities of daily living

ANS: D Therapeutic responses to antiparkinson agents include an improved sense of well-being, improved mental status, increased appetite, increased ability to perform activities of daily living and to concentrate and think clearly, and less intense parkinsonian manifestations

11. A patient has a new prescription for the transdermal form of scopolamine. The nurse knows that this form of scopolamine is used for which condition? a. Angina b. Chronic pain c. Hypertension d. Motion sickness

ANS: D Transdermal scopolamine (Transderm-Scop) is a patch that can be applied just behind the ear 4 to 5 hours before travel for the prevention of motion sickness. The other options are incorrect.

6. The nurse is screening a patient who will be taking a nonspecific/nonselective beta blocker. Which condition, if present, may cause serious problems if the patient takes this medication? a. Angina b. Hypertension c. Glaucoma d. Asthma

ANS: D Nonspecific/nonselective beta-blocking drugs may precipitate bradycardia, hypotension, heart block, heart failure, bronchoconstriction, and/or increased airway resistance. Therefore, any pre-existing respiratory conditions such as asthma might be worsened by the concurrent use of any of these medications.
