The patient is receiving two different drugs. At current dosages and dosage forms, both drugs are absorbed into the circulation in identical amounts. Which term is used to identify this principle? a. Bioequivalent b. Synergistic c. Prodrugs d. Steady state

ANS: A Two drugs absorbed into the circulation in the same amount (in specific dosage forms) have the same bioavailability; thus, they are bioequivalent. A drug's steady state is the physiologic state in which the amount of drug removed via elimination is equal to the amount of drug absorbed from each dose. The term synergistic refers to two drugs, given together, with a resulting effect that is greater than the sum of the effects of each drug given alone. A prodrug is an inactive drug dosage form that is converted to an active metabolite by various biochemical reactions once it is inside the body.

Fluticasone is an inhaled corticosteroid; montelukast is a leukotriene receptor antagonist (LTRA). These types of medications are used for asthma prophylaxis.

The nurse can prevent medication errors by following which principles? (Select all that apply.) a. Assess for allergies after giving medications. b. Use two patient identifiers before giving medications. c. Do not give a medication that another nurse has drawn up in a syringe. d. Minimize the use of verbal and telephone orders. e. Use trade names instead of generic names to avoid confusion.

ANS: B, C, D Measures that prevent medication errors include using two patient identifiers, giving only medications that you have drawn up or prepared, and minimizing the use of verbal and telephone orders. Assessment for allergies should be done before medications are given. Generic names should be used to avoid the many sound-alike trade names of medications.

The nurse is reviewing the uses of oral laxatives. Which conditions are general contraindications to or cautions about the use of oral laxatives? (Select all that apply.) a. Irritable bowel syndrome b. Undiagnosed abdominal pain c. Nausea and vomiting d. Fecal impaction e. Ingestion of toxic substances f. Acute surgical abdomen

ANS: B, C, D, F Cautious use of laxatives is recommended in the presence of these: acute surgical abdomen; appendicitis symptoms, such as abdominal pain, nausea, and vomiting; intestinal obstruction; and undiagnosed abdominal pain. Oral laxatives must not be used with fecal impaction; mineral oil enemas are indicated for fecal impaction. The other options are indications for laxative use.

The nurse is providing patient teaching about antacids. Which statements about antacids are accurate? (Select all that apply.) a. Antacids reduce the production of acid in the stomach. b. Antacids neutralize acid in the stomach. c. Rebound hyperacidity may occur with calcium-based antacids. d. Aluminum-based antacids cause diarrhea. e. Magnesium-based antacids cause diarrhea.

ANS: B, C, E Antacids neutralize acid in the stomach. Magnesium-based antacids cause diarrhea, and aluminum-based antacids cause constipation. Calcium-based antacids often cause rebound hyperacidity.

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.

A patient has a prescription for topically applied 5% fluorouracil (Efudex) cream as part of treatment for basal cell carcinoma on her cheek. Which instructions will the nurse provide to the patient? (Select all that apply.) a. "You must use gloves to apply this medication." b. "You can use clean fingertips to apply the cream, but be sure to wash your hands afterward." c. "You will need to stay out of the sun during therapy with this medication." d. "Apply this medication to the affected site once a day in the evening." e. "Apply this medication to the affected site twice daily." f. "You may have swelling, scaling, burning, and tenderness in the affected area."

ANS: B, C, E, F Fluorouracil may be applied with gloves or clean fingertips, but if fingertips are used, the medication must be washed off thoroughly after application. The medication may cause photosensitivity, as well as local swelling, scaling, burning, and tenderness. The medication is applied twice daily.

The nurse is providing instructions to a patient who has a new prescription for a corticosteroid metered-dose inhaler. Which statement by the patient indicates that further instruction is needed? (Select all that apply.) a. "I will rinse my mouth with water after using the inhaler and then spit out the water." b. "I will gargle after using the inhaler and then swallow." c. "I will clean the plastic inhaler casing weekly by removing the canister and then washing the casing in warm soapy water. I will then let it dry before reassembling." d. "I will use this inhaler for asthma attacks." e. "I will continue to use this inhaler, even if I am feeling better." f. "I will use a peak flow meter to measure my response to therapy."

ANS: B, D The inhaled corticosteroid is a maintenance drug used to prevent asthma attacks; it is not indicated for acute asthma attacks. Rinsing the mouth with water is appropriate and necessary to prevent oral fungal infections; the water is not to be swallowed after rinsing. The patient needs to be given instructions about keeping the inhaler clean, including removing the canister from the plastic casing weekly and washing the casing in warm soapy water. Once the casing is dry, the canister and mouthpiece may be put back together and the cap applied. The glucocorticoid may predispose the patient to oral fungal overgrowth, thus the need for implicit instructions about cleaning inhaling devices. Use of a peak flow meter assists in monitoring the patient's response to therapy. The medication needs to be taken as ordered every day, regardless of whether the patient is feeling better.

A patient is on a chemotherapy regimen in an outpatient clinic and is receiving a chemotherapy drug that is known to be highly emetogenic. The nurse will implement which interventions regarding the pharmacologic management of nausea and vomiting? (Select all that apply.) a. Giving antinausea drugs at the beginning of the chemotherapy infusion b. Administering antinausea drugs 30 to 60 minutes before chemotherapy is started c. For best therapeutic effects, medicating for nausea once the symptoms begin d. Observing carefully for the adverse effects of restlessness and anxiety e. Instructing the patient that the antinausea drugs may cause extreme drowsiness f. Instructing the patient to rise slowly from a sitting or lying position because of possible orthostatic hypotension

ANS: B, E, F Antiemetics should be given before any chemotherapy drug is administered, often 30 to 60 minutes before treatment, but not immediately before chemotherapy is administered. Do not wait until the nausea begins. Most antiemetics cause drowsiness, not restlessness and anxiety. Orthostatic hypotension is a possible adverse effect that may lead to injury.

The nurse is reviewing pharmacology terms for a group of newly graduated nurses. Which sentence defines a drug's half-life? a. The time it takes for the drug to cause half of its therapeutic response b. The time it takes for one half of the original amount of a drug to reach the target cells c. The time it takes for one half of the original amount of a drug to be removed from the body d. The time it takes for one half of the original amount of a drug to be absorbed into the circulation

ANS: C A drug's half-life is the time it takes for one half of the original amount of a drug to be removed from the body. It is a measure of the rate at which drugs are removed from the body. The other options are incorrect definitions of half-life.

A laxative has been ordered for a patient. The nurse checks the patient's medical history and would be concerned if which condition is present? a. High ammonia levels due to liver failure b. Diverticulosis c. Abdominal pain of unknown origin d. Chronic constipation

ANS: C All categories of laxatives share the same general contraindications and precautions, including avoidance in cases of drug allergy and the need for cautious use in the presence of these: acute surgical abdomen; appendicitis symptoms such as abdominal pain, nausea, and vomiting; fecal impaction (mineral oil enemas excepted); intestinal obstruction; and undiagnosed

A patient has been treated with alosetron (Lotronex) for severe irritable bowel syndrome (IBS) for 2 weeks. She calls the clinic and tells the nurse that she has been experiencing constipation for 3 days. The nurse will take which action? a. Advise the patient to increase intake of fluids and fiber. b. Advise the patient to hold the drug for 2 days. c. Instruct the patient to stop taking the drug and to come to the clinic right away to be evaluated. d. Instruct the patient to continue the alosetron and to take milk of magnesia for the constipation.

ANS: C Alosetron must be discontinued immediately if constipation or signs of ischemic colitis occur. The other options are incorrect.

A nurse is giving instructions to a patient who will be receiving oral iron supplements. Which instructions will be included in the teaching plan? a. Take the iron tablets with milk or antacids. b. Crush the pills as needed to help with swallowing. c. Take the iron tablets with meals if gastrointestinal distress occurs. d. If black tarry stools occur, report it to the doctor immediately.

ANS: C Although taking iron tablets with food may decrease absorption, doing so helps to reduce gastrointestinal distress. Antacids and milk may cause decreased iron absorption; iron tablets must be taken whole and not crushed. Black, tarry stools are expected adverse effects of oral iron supplements.

The nurse is monitoring drug levels for a patient who is receiving theophylline. The most recent theophylline level was 22 mcg/mL, and the nurse evaluates this level to be: a. below the therapeutic level. b. at a therapeutic level. c. above the therapeutic level. d. at a toxic level.

ANS: C Although the optimal level may vary from patient to patient, most standard references have suggested that the therapeutic range for theophylline blood level is 10 to 20 mcg/mL. However, most clinicians now advise levels between 5 and 15 mcg/mL.

When given an intravenous medication, the patient says to the nurse, "I usually take pills. Why does this medication have to be given in the arm?" What is the nurse's best answer? a. "The medication will cause fewer adverse effects when given intravenously." b. "The intravenous medication will have delayed absorption into the body's tissues." c. "The action of the medication will begin sooner when given intravenously." d. "There is a lower chance of allergic reactions when drugs are given intravenously."

ANS: C An intravenous (IV) injection provides the fastest route of absorption. The IV route does not affect the number of adverse effects, nor does it cause delayed tissue absorption (it results in faster absorption). The IV route does not affect the number of allergic reactions.

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).

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.

A father calls because his son has head lice. He reports that he used Kwell shampoo three times, but nothing happened." He wants to know what to do now. What will the nurse advise first? a. "It sounds like you need a prescription for a second product, malathion." b. "Try one of the lotion products instead." c. "Be sure to use a nit comb to remove nits from the hair shafts." d. "Try combing through the hair with mineral oil to loosen the lice from the hair shafts."

ANS: C Before trying another product, ensure that he is performing the regimen correctly. Because he only mentioned shampooing, ensure that after each shampoo he is using a nit comb to remove nits, or eggs, from the hair shafts.

The nurse will teach a patient who is receiving oral iron supplements to watch for which expected adverse effects? a. Palpitations b. Drowsiness and dizziness c. Black, tarry stools d. Orange-red discoloration of the urine

ANS: C Black, tarry stools and other gastrointestinal disturbances may occur with the administration of iron preparations. The other options are incorrect.

When administering a bulk-forming laxative, the nurse instructs the patient to drink the medication mixed in a full 8-ounce glass of water. Which statement best explains the rationale for this instruction? a. The water acts to stimulate bowel movements. b. The water will help to reduce the bulk of the intestinal contents. c. These laxatives may cause esophageal obstruction if taken with insufficient water. d. The water acts as a lubricant to produce bowel movements.

ANS: C Bulk-forming drugs increase water absorption, which results in greater total volume (bulk) of the intestinal contents. Bulk-forming laxatives tend to produce normal, formed stools. Their action is limited to the gastrointestinal tract, so there are few, if any, systemic effects. However, they need to be taken with liberal amounts of water to prevent esophageal obstruction and fecal impaction.

A patient is receiving a third session of chemotherapy with daunorubicin (Cerubidine). The nurse will assess the patient for which signs of a potential severe toxic effect of this drug? a. Tinnitus and hearing loss b. Numbness and tingling in the fingers c. A weight gain of 2 pounds or more in 24 hours d. Decreased blood urea nitrogen and creatinine levels

ANS: C Cardiac toxicity may occur, so frequent checking of heart and breath sounds is necessary and daily weights need to be recorded (with reporting of an increase of 2 pounds or more in 24 hours or 5 pounds or more in 1 week).

A patient is taking linaclotide (Linzess) to treat irritable bowel syndrome (IBS). The nurse will monitor this patient for which adverse effect? a. Chest pain b. Chronic constipation c. Abdominal pain d. Elevated blood glucose levels

ANS: C Common adverse effects of linaclotide (Linzess) are diarrhea, abdominal pain, and flatulence. Elevated blood glucose levels, chest pain, and chronic constipation are not adverse effects of linaclotide.

When giving dextromethorphan, the nurse understands that this drug suppresses the cough reflex by which mechanism of action? a. Causing depression of the central nervous system b. Anesthetizing the stretch receptors c. Having direct action on the cough center d. Decreasing the viscosity of the bronchial secretions

ANS: C Dextromethorphan suppresses the cough reflex through a direct action on the cough center. The other options are incorrect.

The nurse is reviewing a list of verbal medication orders. Which is the proper notation of the dose of the drug ordered? a. Digoxin .125 mg b. Digoxin .1250 mg c. Digoxin 0.125 mg d. Digoxin 0.1250 mg

ANS: C Digoxin 0.125 mg illustrates the correct notation with a leading zero before the decimal point. Omitting the leading zero may cause the order to be misread, resulting in a large drug overdose. Digoxin .125 mg and digoxin .1250 mg do not have the leading zero before the decimal point. Digoxin 0.1250 mg has a trailing zero, which also is incorrect.

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.

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

A gardener needs a decongestant because of seasonal allergy problems and asks the nurse whether he should take an oral form or a nasal spray. Which of these is a benefit of orally administered decongestants? a. Immediate onset b. A more potent effect c. Lack of rebound congestion d. Shorter duration

ANS: C Drugs administered by the oral route produce prolonged decongestant effects, but the onset of action is more delayed and the effect less potent than those of decongestants applied topically. However, the clinical problem of rebound congestion associated with topically administered drugs is almost nonexistent with oral dosage forms.

The nurse will be giving ophthalmic drugs to a patient with glaucoma. Which drug is given intravenously to reduce intraocular pressure when other medications are not successful? a. Tobramycin (Tobrex) b. Bacitracin (AK-Tracin) c. Mannitol (Osmitrol) d. Ketorolac (Acular)

ANS: C Drugs used to reduce intraocular pressure include osmotic diuretics such as mannitol, which is given intravenously. Tobramycin and bacitracin are antibiotics; ketorolac has anti-inflammatory actions.

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.

A patient with end-stage renal failure has been admitted to the hospital for severe anemia. She is refusing blood transfusions. The nurse anticipates drug therapy with which drug to stimulate the production of red blood cells? a. Folic acid b. Cyanocobalamin (vitamin B12) c. Epoetin alfa (Epogen) d. Filgrastim (Neupogen)

ANS: C Epoetin alfa is a colony-stimulating factor that is responsible for erythropoiesis, or formation of red blood cells. The other options are incorrect.

A 75-year-old woman comes into the clinic with complaints of muscle twitching, nausea, and headache. She tells the nurse that she has been taking sodium bicarbonate five or six times a day for the past 3 weeks. The nurse will assess for which potential problem that may occur with overuse of sodium bicarbonate? a. Constipation b. Metabolic acidosis c. Metabolic alkalosis d. Excessive gastric mucus

ANS: C Excessive use of sodium bicarbonate may lead to systemic alkalosis. The other options are incorrect.

When taking a telephone order for a medication, which action by the nurse is most appropriate? a. Verify the order with the charge nurse. b. Call back the prescriber to review the order. c. Repeat the order to the prescriber before hanging up the telephone. d. Ask the pharmacist to double-check the order.

ANS: C For telephone or verbal orders, repeat the order back to the prescriber before hanging up the telephone. The other options are incorrect.

During therapy with the hematopoietic drug epoetin alfa (Epogen), the nurse instructs the patient about adverse effects that may occur, such as: a. anxiety. b. drowsiness. c. hypertension. d. constipation.

ANS: C Hypertension is an adverse effect of hematopoietic drugs, along with headache, fever, pruritus, rash, nausea, vomiting, arthralgia, cough, and injection site reaction. The other options are incorrect

What is the nurse's priority action if extravasation of an antineoplastic drug occurs during intravenous (IV) administration? a. Reduce the infusion rate. b. Discontinue the IV, and apply warm compresses. c. Stop the infusion immediately, but leave the IV catheter in place. d. Change the infusion to normal saline, and inject the area with hydrocortisone.

ANS: C If extravasation is suspected, administration of the drug must be stopped immediately but the IV catheter left in place and the appropriate antidote instilled through the existing IV tube, after which the needle may be removed. The other options are incorrect.

A patient is receiving irinotecan (Camptosar), along with other antineoplastic drugs, as treatment for ovarian cancer. The nurse will monitor for which potentially life-threatening adverse effect that is associated with this drug? a. Severe stomatitis b. Bone marrow suppression c. Delayed-onset cholinergic diarrhea d. Immediate and severe nausea and vomiting

ANS: C In addition to producing hematologic adverse effects, irinotecan has been associated with severe diarrhea, known as cholinergic diarrhea, which may occur during infusions. Delayed diarrhea may occur 2 to 10 days after infusion of irinotecan. It is recommended that this condition be treated with atropine unless use of that drug is strongly contraindicated. This diarrhea can be severe and even life threatening.

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.

The nurse is reviewing the use of ophthalmic preparations. Indications for the direct- and indirect-acting miotics include which condition? a. Cataracts b. Removal of foreign bodies c. Open-angle glaucoma d. Ocular infections

ANS: C Indications for the direct- and indirect-acting miotics include open-angle glaucoma, angle-closure glaucoma, ocular surgery, and convergent strabismus.

The nurse is giving oral mineral oil as an ordered laxative dose. The nurse will take measures to prevent which potential problem that may occur with mineral oil? a. Fecal impaction b. Electrolyte imbalances c. Lipid pneumonia d. Esophageal blockage

ANS: C Lipid pneumonia may occur if the oral mineral oil is accidentally aspirated into the respiratory tract. The other options are incorrect.

While recovering from surgery, a 74-year-old woman started taking a stimulant laxative, senna (Senokot), to relieve constipation caused by the pain medications. Two weeks later, at her follow-up appointment, she tells the nurse that she likes how "regular" her bowel movements are now that she is taking the laxative. Which teaching principle is appropriate for this patient? a. She needs to be sure to take this medication with plenty of fluids. b. It is important to have a daily bowel movement to promote bowel health. c. Long-term use of laxatives often results in decreased bowel tone and may lead to dependency. d. She needs to switch to glycerin suppositories to continue having daily bowel movements.

ANS: C Long-term use of laxatives may lead to dependency. Patients need to be taught that daily bowel movements are not necessary for bowel health.

At 0900, the nurse is about to give morning medications, and the patient has asked for a dose of antacid for severe heartburn. Which schedule for the antacid and medications is correct? a. Give both the antacid and medications at 0900. b. Give the antacid at 0900, and then the medications at 0930. c. Give the medications at 0900, and then the antacid at 1000. d. Give the medications at 0900, and then the antacid at 0915.

ANS: C Medications are not to be taken, unless prescribed, within 1 to 2 hours of taking an antacid because of the impact on the absorption of many medications in the stomach.

A patient who has been on methotrexate therapy is experiencing mild pain. The patient is asking for aspirin for the pain. The nurse recognizes that which of these is true in this situation? a. The aspirin will aggravate diarrhea. b. The aspirin will masks signs of infection. c. Aspirin can lead to methotrexate toxicity. d. The aspirin will cause no problems for the patient on methotrexate.

ANS: C Methotrexate interacts with weak organic acids, such as aspirin, and can lead to toxicity by displacing the methotrexate from protein-binding sites

During chemotherapy, a patient develops severe diarrhea caused by a vasoactive intestinal peptide-secreting tumor (VIPoma). The nurse expects to administer which drug for this problem? a. Dexrazoxane (Zinecard) b. Allopurinol (Zyloprim) c. Octreotide (Sandostatin) d. Bismuth subsalicylate (Pepto-Bismol)

ANS: C Octreotide (Sandostatin) is used for the management of a cancer-related condition called carcinoid crisis and treatment of the severe diarrhea caused by vasoactive intestinal peptide-secreting tumors (VIPomas). The other options are incorrect.

The nurse is assessing a child with otitis media. Which statement about otitis media is correct? a. It is treated with over-the-counter medications. b. In children, it commonly follows a lower respiratory tract infection. c. Common symptoms include pain, fever, malaise, and a sensation of fullness in the ears. d. Hearing deficits are associated only with inner ear infections, not with otitis media.

ANS: C Otitis media is rarely treated with over-the-counter medications and commonly follows an upper respiratory tract infection in children. Hearing deficits may occur if prompt therapy is not started. Common symptoms include pain, fever, malaise, and a sensation of fullness in the ear.

A patient is severely constipated and needs immediate relief. The nurse knows that which class of laxative will provide the most rapid results? a. Bulk-forming laxative, such as psyllium (Metamucil) b. Stool softener, such as docusate salts (Colace) c. Magnesium hydroxide (MOM) d. Magnesium oxide tablets

ANS: C Saline laxatives such as magnesium hydroxide (MOM) produce a watery stool, usually within 3 to 6 hours of ingestion. Bulk-forming laxatives such as psyllium do not produce a bowel movement rapidly. Stool softeners such as docusate salts do not cause patients to defecate; they simply soften the stool to ease its passage. Magnesium oxide tablets are used as magnesium supplements, not as laxatives.

A patient with motion sickness is planning a cross-country car trip and has a new prescription for a scopolamine transdermal patch (Transderm-Scop). The nurse provides teaching for the use of this patch medication. The patient shows a correct understanding of the teaching with which statement? a. "I will change the patch every day." b. "I will change the patch every other day." c. "I will change the patch every 3 days." d. "I will remove the patch only if it stops working."

ANS: C Scopolamine patches are 72-hour doses and are changed every 3 days. The other options are incorrect.

When hanging a new infusion bag of a chemotherapy drug, the nurse accidentally spills a small amount of the solution onto the floor. Which action by the nurse is appropriate? a. Let it dry, and then mop the floor. b. Wipe the area with a disposable paper towel. c. Use a spill kit to clean the area. d. Ask the housekeeping department to clean the floor.

ANS: C Special spill kits are employed to clean up even the smallest chemotherapy spills. These precautions are necessary to protect the health care provider from the cytotoxic effects of these drugs.

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.

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.

The patient wants to take the herb valerian to help him rest at night. The nurse would be concerned about potential interactions if he is taking a medication from which class of drugs? a. Digitalis b. Anticoagulants c. Sedatives d. Immunosuppressants

ANS: C Valerian may cause increased central nervous system depression if used with sedatives. Digitalis, anticoagulants, and immunosuppressants do not have interactions with valerian.

When reviewing a patient's medical record, the nurse notes an order for carbamide peroxide eardrops. Based on this information, the nurse interprets that these eardrops are being used for which purpose? a. To reduce inflammation b. To reduce production of cerumen c. To loosen the cerumen for easier removal d. To inhibit growth of microorganisms in the external canal

ANS: C Wax emulsifiers such as carbamide peroxide work to loosen the cerumen for easier removal. The other options are incorrect.

During an admission assessment, the nurse discovers that the patient does not speak English. Which is considered the ideal resource for translation? a. A family member of the patient b. A close family friend of the patient c. A translator who does not know the patient d. Prewritten note cards with both English and the patient's language

ANS: C The nurse should communicate with the patient in the patient's native language if at all possible. If the nurse is not able to speak the patient's native language, a translator should be made available so as to prevent communication problems, minimize errors, and help boost the patient's level of trust and understanding of the nurse. In practice, this translator may be another nurse or health care professional, a nonprofessional member of the health care team, or a layperson, family member, adult friend, or religious leader or associate. However, it is best to avoid family members as translators, if possible, because of issues with bias, misinterpretation, and potential confidentiality issues.

A patient will be taking bismuth subsalicylate (Pepto-Bismol) to control diarrhea. When reviewing the patient's other ordered medications, the nurse recognizes that which medication will interact significantly with the Pepto-Bismol? a. Acetaminophen (Tylenol), an analgesic b. Levothyroxine (Synthroid), a thyroid replacement drug c. Warfarin (Coumadin), an anticoagulant d. Fluoxetine (Prozac), an antidepressant

ANS: C The oral anticoagulant warfarin is more likely to cause increased bleeding times or bruising when co-administered with adsorbents. This is thought to be because the adsorbents bind to vitamin K, which is needed to make certain clotting factors. Vitamin K is synthesized by the normal bacterial flora in the bowel. The other options are incorrect

When evaluating a patient's use of a metered-dose inhaler (MDI), the nurse notes that the patient is unable to coordinate the activation of the inhaler with her breathing. What intervention is most appropriate at this time? a. Notify the doctor that the patient is unable to use the MDI. b. Obtain an order for a peak flow meter. c. Obtain an order for a spacer device. d. Ask the prescriber if the medication can be given orally.

ANS: C The use of a spacer may be indicated with metered-dose inhalers, especially if success with inhalation is limited. The other options are not appropriate interventions.

A patient calls the clinic to ask about taking cranberry dietary supplement capsules because a friend recommended them. The nurse will discuss which possible concern when a patient is taking cranberry supplements? a. It may increase the risk for bleeding if the patient is taking anticoagulants. b. It may increase the risk of toxicity of some psychotherapeutic drugs. c. It may reduce elimination of drugs that are excreted by the kidneys. d. Cranberry may increase the intensity and duration of effects of caffeine.

ANS: C The use of cranberry decreases the elimination of many drugs that are renally excreted. The other concerns do not occur with cranberry supplements.

The nurse is developing a care plan for a patient who will be self-administering insulin injections. Which statement reflects a measurable outcome? a. The patient will know about self-administration of insulin injections. b. The patient will understand the principles of self-administration of insulin injections. c. The patient will demonstrate the proper technique of self-administering insulin injections. d. The patient will comprehend the proper technique of self-administering insulin injections.

ANS: C The word demonstrate is a measurable verb, and measurable terms should be used when developing goals and outcome criteria statements. The other options are incorrect because the terms know, understand, and comprehend are not measurable terms.

A woman who is in the first trimester of pregnancy has been experiencing severe morning sickness. She asks, "I've heard that ginger tablets may be a natural way to ease the nausea and vomiting. Is it okay to try them?" What is the nurse's best response? a. "They are a safe and natural remedy for nausea when you are pregnant." b. "Go ahead and try them, but stop taking them once the nausea is relieved." c. "Some health care providers do not recommend ginger during pregnancy. Let's check with your provider." d. "You will need to wait until after the first trimester to try them."

ANS: C There is some anecdotal evidence that ginger may have abortifacient properties, and for this reason some clinicians do not recommend its use during pregnancy.

The prescriber has changed the patient's medication regimen to include the leukotriene receptor antagonist (LTRA) montelukast (Singulair) to treat asthma. The nurse will emphasize which point about this medication? a. The proper technique for inhalation must be followed. b. The patient needs to keep it close by at all times to treat acute asthma attacks. c. It needs to be taken every day on a continuous schedule, even if symptoms improve. d. When the asthma symptoms improve, the dosage schedule can be tapered and eventually discontinued.

ANS: C These drugs are indicated for chronic, not acute, asthma and are to be taken every day on a continuous schedule, even if symptoms improve. These drugs are taken orally

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.

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.

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.

The nurse is teaching a patient about proper administration of eardrops. Which statements are correct? (Select all that apply.) a. Remove cerumen with a cotton-tipped swab before instilling the drops. b. Instill the drops while still cool from refrigeration. c. Warm the eardrops to room temperature before instillation. d. The adult patient should pull the pinna of the ear up and back. e. Insert a dry cotton ball firmly into the ear canal after instillation. f. Massage the earlobe after instillation.

ANS: C, D, E Remove cerumen before instillation by irrigation, not with cotton-tipped swabs. The drops must be at room temperature; cold drops may cause dizziness or other discomfort. Hold the pinna of the ear up and back when giving eardrops to adults or children older than 3 years of age. Massage the tragus area after instillation to encourage flow through the ear canal. A small cotton ball may be inserted gently into the ear canal to keep the drug in place, but do not force or jam it into the ear canal. Gentle massage to the tragus area of the ear (not the earlobe) may also help to increase coverage of the medication after it is given.

When teaching a patient who will be receiving antihistamines, the nurse will include which instructions? (Select all that apply.) a. "Antihistamines are generally safe to take with over-the-counter medications." b. "Take the medication on an empty stomach to maximize absorption of the drug." c. "Take the medication with food to minimize gastrointestinal distress." d. "Drink extra fluids if possible." e. "Antihistamines may cause restlessness and disturbed sleep." f. "Avoid activities that require alertness until you know how adverse effects are tolerated."

ANS: C, D, F Antihistamines should be taken with food, even though this slightly reduces the absorption of the drug, so as to minimize the gastrointestinal upset that can occur. Over-the-counter medications must not be taken with an antihistamine unless approved by the physician because of the serious drug interactions that may occur. Drinking extra fluids will help to ease the removal of secretions, and activities that require alertness, such as driving, must not be engaged in until the patient knows how he or she responds to the sedating effects of antihistamines.

Which drugs would be affected by the first-pass effect? (Select all that apply.) a. Morphine given by IV push injection b. Sublingual nitroglycerin tablets c. Diphenhydramine (Benadryl) elixir d. Levothyroxine (Synthroid) tablets e. Transdermal nicotine patches f. Esomeprazole (Nexium) capsules g. Penicillin given by IV piggyback infusion

ANS: C, D, F Orally administered drugs (elixirs, tablets, capsules) undergo the first-pass effect because they are metabolized in the liver after being absorbed into the portal circulation from the small intestine. IV medications (IV push and IV piggyback) enter the bloodstream directly and do not go directly to the liver. Sublingual tablets and transdermal patches also enter the bloodstream without going directly to the liver, thus avoiding the first-pass effect.

Which nursing diagnosis is appropriate for the patient who has just received a prescription for a new medication? a. Noncompliance related to new drug therapy b. Impaired memory related to new drug therapy c. Lack of knowledge regarding newly prescribed drug therapy d. Deficient knowledge related to newly prescribed drug therapy

ANS: D A patient who has a limited understanding of newly prescribed drug therapy may have the nursing diagnosis of deficient knowledge. Noncompliance is incorrect because that term implies that the patient does not follow a recommended regimen, which is not the case with a newly prescribed drug. Impaired memory is not appropriate in this situation. "Lack of knowledge" is not a nursing diagnosis.

When monitoring the patient receiving an intravenous infusion to reduce blood pressure, the nurse notes that the patient's blood pressure is extremely low, and the patient is lethargic and difficult to awaken. This would be classified as which type of adverse drug reaction? a. Adverse effect b. Allergic reaction c. Idiosyncratic reaction d. Pharmacologic reaction

ANS: D A pharmacologic reaction is an extension of a drug's normal effects in the body. In this case, the antihypertensive drug lowered the patient's blood pressure levels too much. The other options do not describe a pharmacologic reaction. An adverse effect is a predictable, well-known adverse drug reaction that results in minor or no changes in patient management. An allergic reaction (also known as a hypersensitivity reaction) involves the patient's immune system. An idiosyncratic reaction is unexpected and is defined as a genetically determined abnormal response to normal dosages of a drug.

The nurse is teaching a 16-year-old patient who has a new diagnosis of type 1 diabetes about blood glucose monitoring and the importance of regulating glucose intake. When developing a teaching plan for this teenager, which of Erikson's stages of development should the nurse consider? a. Trust versus mistrust b. Intimacy versus isolation c. Industry versus inferiority d. Identity versus role confusion

ANS: D According to Erikson, the adolescent (12 to 18 years of age) is in the identity versus role confusion stage of development. Trust versus mistrust reflects the infancy stage; intimacy versus isolation reflects the young adulthood stage; and industry versus inferiority reflects the school-age stage of development.

The nurse is reviewing the medication orders for a patient who will be taking an H2 antagonist. Which drug may have an interaction if taken along with the H2 antagonist? a. Ibuprofen (Motrin) b. Ranitidine (Zantac) c. Tetracycline (Doryx) d. Ketoconazole (Nizoral)

ANS: D All H2 receptor antagonists may inhibit the absorption of certain drugs, such as the antifungal ketoconazole, that require an acidic gastrointestinal environment for gastric absorption. The other options are incorrect.

The nurse will instruct patients about a possible systemic effect that may occur if excessive amounts of topically applied adrenergic nasal decongestants are used. Which systemic effect may occur? a. Heartburn b. Bradycardia c. Drowsiness d. Palpitations

ANS: D Although a topically applied adrenergic nasal decongestant can be absorbed into the bloodstream, the amount absorbed is usually too small to cause systemic effects at normal dosages. Excessive dosages of these medications, however, are more likely to cause systemic effects elsewhere in the body. These may include cardiovascular effects, such as hypertension and palpitations, and central nervous system effects such as headache, nervousness, and dizziness. The other options are incorrect.

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.

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.

A woman suffered a second-degree burn of the skin on her arm and hand while cooking breakfast. After examination in the urgent care center, silver sulfadiazine cream (Silvadene) is ordered for the burned area. The nurse will apply the medication using which procedure? a. Gently patting a moderate amount over the burned area b. Massaging the cream completely into the wound c. Applying a thick layer over the burned area, and then leaving the area open d. Applying a thin layer with a sterile, gloved hand to clean and débrided areas

ANS: D Apply a thin layer of medication with a sterile, gloved hand to clean and débrided wounds. The other options are incorrect.

A child has been diagnosed with impetigo, a skin infection. The nurse anticipates that which drug will be used to treat this condition? a. Spinosad (Natroba) b. Nystatin (Mycostatin) c. Acyclovir (Zovirax) d. Bacitracin

ANS: D Bacitracin is applied topically for the treatment of local skin infections caused by susceptible aerobic and anaerobic gram-positive organisms, which can lead to impetigo. Spinosad (Natroba) is used for pediculosis; nystatin is an antifungal drug; and acyclovir is an antiviral drug.

A patient is admitted to the hospital for possible septicemia. He has a large pressure ulcer on his heel that is open and includes necrotic tissue. However, his prothrombin time/international normalized ratio (PT/INR) values are too high to permit surgical débridement at this time. The nurse expects that which wound-care product will be used to treat the wound? a. Cadexomer iodine (Iodosorb) b. Biafine topical emulsion c. Povidone-iodine (Betadine) d. Collagenase (Santyl)

ANS: D Because this patient has an elevated PT/INR, he cannot receive surgical débridement because of concerns about excessive bleeding. Collagenase is useful for patients taking anticoagulants and for those in whom surgery is contraindicated; it selectively removes necrotic tissue but does not harm normal tissue. Cadexomer iodine is not appropriate for a wound with necrotic tissue. Betadine is used as a skin cleanser; biafine is indicated for radiation dermatitis.

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.

A 60-year-old patient is on several new medications and expresses worry that she will forget to take her pills. Which action by the nurse would be most helpful in this situation? a. Teaching effective coping strategies b. Asking the patient's prescriber to reduce the number of drugs prescribed c. Assuring the patient that she will not forget once she is accustomed to the routine d. Assisting the patient with obtaining and learning to use a calendar or pill container

ANS: D Calendars, pill containers, or diaries may be helpful to patients who may forget to take prescribed drugs as scheduled. The nurse must ensure that the patient knows how to use these reminder tools. Teaching coping strategies is a helpful suggestion but will not help with remembering to take medications. Asking the prescriber to reduce the number of drugs that are prescribed is not an appropriate action by the nurse. Assuring the patient that she will not forget is false reassurance by the nurse and inappropriate when education is needed.

A patient has been taking the corticosteroid dexamethasone (Decadron) but has developed bacterial conjunctivitis and has a prescription for gentamicin (Garamycin) ointment. The nurse notes that which interaction is possible if the two drugs are used together? a. The infection may become systemic. b. The gentamicin effects may become more potent. c. The corticosteroid may cause overgrowth of nonsusceptible organisms. d. Immunosuppression may make it more difficult to eliminate the eye infection.

ANS: D Concurrent use of corticosteroids, such as dexamethasone and ophthalmic antimicrobials, may cause immunosuppression that may make it more difficult to eliminate the eye infection.

The nurse is developing a plan of care for a patient who is experiencing gastrointestinal adverse effects, including anorexia and nausea, after the first course of antineoplastic therapy. What is an appropriate outcome for this patient when dealing with this problem? a. The patient will eat three balanced meals a day within 2 days. b. The patient will return to normal eating pattern within 4 weeks. c. The patient will maintain normal weight by consuming healthy snacks as tolerated. d. The patient will maintain a diet of small, frequent feedings with nutrition supplements within 2 weeks.

ANS: D Consuming small, frequent meals with nutritional supplements, and maintaining a bland diet help to improve nutrition during antineoplastic therapy

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.

The nurse is administering eardrops that contain a combination of an antibiotic and a corticosteroid. What is the rationale for combining these two drugs in eardrops? a. The combination works to help soften and eliminate cerumen. b. The corticosteroid reduces pain associated with ear infections. c. The drops help to eliminate fungal infections. d. The corticosteroid reduces the inflammation and itching associated with ear infections.

ANS: D Corticosteroids, such as hydrocortisone, are commonly used in combination with otic antibiotics to reduce the inflammation and itching associated with ear infections. Antibiotics do not eliminate fungal infections. The other options are incorrect.

A patient has been receiving epoetin alfa (Epogen) for severe iron-deficiency anemia. Today, the provider changed the order to darbepoetin (Aranesp). The patient questions the nurse, "What is the difference in these drugs?" Which response by the nurse is correct? a. "There is no difference in these two drugs." b. "Aranesp works faster than Epogen to raise your red blood cell count." c. "Aranesp is given by mouth, so you will not need to have injections." d. "Aranesp is a longer-acting form, so you will receive fewer injections."

ANS: D Darbepoetin (Aranesp) is longer-acting than epoetin alfa (Epogen); therefore, fewer injections are required. The other options are incorrect.

The nurse is setting up a teaching session with an 85-year-old patient who will be going home on anticoagulant therapy. Which educational strategy would reflect consideration of the age-related changes that may exist with this patient? a. Show a video about anticoagulation therapy. b. Present all the information in one session just before discharge. c. Give the patient pamphlets about the medications to read at home. d. Develop large-print handouts that reflect the verbal information presented.

ANS: D Developing large-print handouts addresses altered perception in two ways. First, by using visual aids to reinforce verbal instructions, one addresses the possibility of decreased ability to hear high-frequency sounds. By developing the handouts in large print, one addresses the possibility of decreased visual acuity. Showing a video does not allow discussion of the information; furthermore, the text and print may be small and difficult to read and understand. Presenting all the information in one session before discharge also does not allow for discussion, and the patient may not be able to hear or see the information sufficiently. Because of the possibility of decreased short-term memory and slowed cognitive function, giving pamphlets to read may not be appropriate.

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.

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.

When administering a new medication to a patient, the nurse reads that it is highly protein bound. Assuming that the patient's albumin levels are normal, the nurse would expect which result, as compared to a medication that is not highly protein bound? a. Renal excretion will be faster. b. The drug will be metabolized quickly. c. The duration of action of the medication will be shorter. d. The duration of action of the medication will be longer.

ANS: D Drugs that are bound to plasma proteins are characterized by longer duration of action. Protein binding does not make renal excretion faster, does not speed up drug metabolism, and does not cause the duration of action to be shorter.

When administering drugs, the nurse remembers that the duration of action of a drug is defined as which of these? a. The time it takes for a drug to elicit a therapeutic response b. The amount of time needed to remove a drug from circulation c. The time it takes for a drug to achieve its maximum therapeutic response d. The time period at which a drug's concentration is sufficient to cause a therapeutic response

ANS: D Duration of action is the time during which drug concentration is sufficient to elicit a therapeutic response. The other options do not define duration of action. A drug's onset of action is the time it takes for the drug to elicit a therapeutic response. A drug's peak effect is the time it takes for the drug to reach its maximum therapeutic response. Elimination is the length of time it takes to remove a drug from circulation.

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.

The nurse is administering folic acid to a patient with a new diagnosis of anemia. Which statement about treatment with folic acid is true? a. Folic acid is used to treat any type of anemia. b. Folic acid is used to treat iron-deficiency anemia. c. Folic acid is used to treat pernicious anemia. d. The specific cause of the anemia needs to be determined before treatment.

ANS: D Folic acid should not be used to treat anemias until the underlying cause and type of anemia have been identified. Administering folic acid to a patient with pernicious anemia may correct the hematologic changes of anemia, but the symptoms of pernicious anemia (which is due to a vitamin B12 deficiency, not a folic acid deficiency) may be deceptively masked. The other options are incorrect.

The nurse is administrating eardrops that have been refrigerated. Which action by the nurse is correct before administering the drops? a. Leave the drops in the refrigerator until use. b. Heat the chilled solution for 10 seconds in the microwave. c. Soak the bottle for 60 seconds in a container of very hot water. d. Take the drops out of the refrigerator 1 hour before the dose is due.

ANS: D Give eardrops at room temperature. If the pharmacy indicates that the drug is to be refrigerated, it should be taken out of the refrigerator up to 1 hour before it is to be instilled so that it can warm up to room temperature. They are not to be placed in the microwave or soaked in hot water; eardrops that are overheated may lose potency. Administration of solutions that are too cold may cause a vestibular reaction that includes vomiting and dizziness. If the solution has been refrigerated, allow it to warm to room temperature.

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.

The nurse is reviewing the medical record of a patient before giving a new order for iron sucrose (Venofer). Which statement regarding the administration of iron sucrose is correct? a. The medication is given with food to reduce gastric distress. b. Iron sucrose is contraindicated if the patient has renal disease. c. A test dose will be administered before the full dose is given. d. The nurse will monitor the patient for hypotension during the infusion.

ANS: D Iron sucrose (Venofer) is an injectable iron product indicated for the treatment of iron-deficiency anemia in patients with chronic renal disease. It is also used for patients without kidney disease. Its risk of precipitating anaphylaxis is much less than that of iron dextran, and a test dose is not required. Hypotension is the most common adverse effect and appears to be related to infusion rate. Low-weight elderly patients appear to be at greatest risk for hypotension.

A woman who is planning to become pregnant should ensure that she receives adequate levels of which supplement to reduce the risk for fetal neural tube defects? a. Vitamin B12 b. Vitamin D c. Iron d. Folic acid

ANS: D It is recommended that administration of folic acid be begun at least 1 month before pregnancy and continue through early pregnancy to reduce the risk for fetal neural tube defects.

During an admission assessment, the patient tells the nurse that he has been self-treating his heartburn for 1 year with over-the-counter Prilosec OTC (omeprazole, a proton pump inhibitor). The nurse is aware that this self-treatment may have which result? a. No serious consequences b. Prevention of more serious problems, such as an ulcer c. Chronic constipation d. Masked symptoms of serious underlying diseases

ANS: D Long-term self-medication with antacids may mask symptoms of serious underlying diseases, such as bleeding ulcer or malignancy. Patients with ongoing symptoms need to undergo regular medical evaluations, because additional medications or other interventions may be needed.

The nurse is teaching a patient who will be taking a proton pump inhibitor as long-term therapy about potential adverse effects. Which statement is correct? a. Proton pump inhibitors can cause diarrhea. b. These drugs can cause nausea and anorexia. c. Proton pump inhibitors cause drowsiness. d. Long-term use of these drugs may contribute to osteoporosis.

ANS: D New concerns have arisen over the potential for long-term users of proton pump inhibitors (PPIs) to develop osteoporosis. This is thought to be due to the inhibition of stomach acid, and it is speculated that PPIs speed up bone mineral loss. The other options are incorrect.

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.

The patient is complaining of a headache and asks the nurse which over-the-counter medication form would work the fastest to help reduce the pain. Which medication form will the nurse suggest? a. A capsule b. A tablet c. An enteric-coated tablet d. A powder

ANS: D Of the types of oral medications listed, the powder form would be absorbed the fastest, thus having a faster onset. The tablet, the capsule, and, finally, the enteric-coated tablet would be absorbed next, in that order.

A patient is taking omeprazole (Prilosec) for the treatment of gastroesophageal reflux disease (GERD). The nurse will include which statement in the teaching plan about this medication? a. "Take this medication once a day after breakfast." b. "You will be on this medication for only 2 weeks for treatment of the reflux disease." c. "The medication may be dissolved in a liquid for better absorption." d. "The entire capsule must be taken whole, not crushed, chewed, or opened."

ANS: D Omeprazole needs to be taken before meals, and an entire capsule must be taken whole, not crushed, chewed, opened, or dissolved in liquid when treating GERD. This medication is used on a long-term basis to maintain healing.

When educating a patient recently placed on inhaled corticosteroids, the nurse will discuss which potential adverse effects? a. Fatigue and depression b. Anxiety and palpitations c. Headache and rapid heart rate d. Oral candidiasis and dry mouth

ANS: D Oral candidiasis and dry mouth are two possible adverse effects of inhaled corticosteroids. The other responses are incorrect.

The nurse is teaching a patient with iron-deficiency anemia about foods to increase iron intake. Which food may enhance the absorption of oral iron forms? a. Milk b. Yogurt c. Antacids d. Orange juice

ANS: D Orange juice contains ascorbic acid, which enhances the absorption of oral iron forms; antacids, milk, and yogurt may interfere with absorption.

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.

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.

A patient is about to undergo a diagnostic bowel procedure. The nurse expects which drug to be used to induce total cleansing of the bowel? a. Docusate sodium (Colace) b. Lactulose (Enulose) c. Mineral oil d. Polyethylene glycol 3350 (GoLYTELY)

ANS: D Polyethylene glycol is a very potent laxative that induces total cleansing of the bowel and is most commonly used before diagnostic or surgical bowel procedures. The other options are incorrect.

A patient who has been on antibiotic therapy for 2 weeks has developed persistent diarrhea. The nurse expects which medication class to be ordered to treat this diarrhea? a. Lubricants b. Adsorbents c. Anticholinergics d. Probiotics .

ANS: D Probiotics work by replenishing bacteria that may have been destroyed by antibiotic therapy, thus restoring the balance of normal flora and suppressing the growth of diarrhea-causing bacteria

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.

A patient is receiving ocular cyclosporine (Restasis) and also has an order for an artificial tears product. The nurse includes which instructions in the teaching plan for these medications? a. "These two eye drugs cannot be given together. Let's check with your prescriber." b. "You may take these two drugs together at the same time." c. "First take the artificial tears, and then take the Restasis after 5 minutes." d. "Take the Restasis first, and then wait 15 minutes before taking the artificial tears."

ANS: D Restasis can be used together with artificial tears if the drugs are given 15 minutes apart. The other options are incorrect.

When the nurse teaches a skill such as self-injection of insulin to the patient, what is the best way to set up the teaching/learning session? a. Provide written pamphlets for instruction. b. Show a video, and allow the patient to practice as needed on his own. c. Verbally explain the procedure, and provide written handouts for reinforcement. d. After demonstrating the procedure, allow the patient to do several return demonstrations.

ANS: D Return demonstration allows the nurse to evaluate the patient's newly learned skills. The techniques in the other options are incorrect because those suggestions do not allow for evaluation of the patient's technique.

The nurse is providing instructions about the Advair inhaler (fluticasone propionate and salmeterol). Which statement about this inhaler is accurate? a. It is indicated for the treatment of acute bronchospasms. b. It needs to be used with a spacer for best results. c. Patients need to avoid drinking water for 1 hour after taking this drug. d. It is used for the prevention of bronchospasms.

ANS: D Salmeterol is a long-acting beta2 agonist bronchodilator, while fluticasone is a corticosteroid. In combination, they are used for the maintenance treatment of asthma and COPD. As a long-acting inhaler, Advair is not appropriate for treatment of acute bronchospasms. The other statements are incorrect.

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.

A patient is complaining of excessive and painful gas. The nurse checks the patient's medication orders and prepares to administer which drug for this problem? a. Famotidine (Pepcid) b. Aluminum hydroxide and magnesium hydroxide (Maalox or Mylanta) c. Calcium carbonate (Tums) d. Simethicone (Mylicon)

ANS: D Simethicone alters the elasticity of mucus-coated bubbles, causing them to break, and is an over-the-counter antiflatulent. The other options are incorrect.

A 25-year-old woman is visiting the prenatal clinic and shares with the nurse her desire to go "natural" with her pregnancy. She shows the nurse a list of herbal remedies that she wants to buy so that she can "avoid taking any drugs." Which statement by the nurse is correct? a. "Most herbal remedies are not harmful and are safe for use during pregnancy." b. "Please read each label carefully before use to check for cautionary warnings." c. "Keep in mind that products from different manufacturers are required to contain consistent amounts of the herbal products." d. "It's important to remember that herbal remedies do not have proven safety ratings for pregnant women."

ANS: D The fact that a drug is an herbal or a dietary supplement does not mean that it can be safely administered to children, infants, or pregnant or lactating women. Many herbal products have not been tested for safety during pregnancy. Simply reading the labels may not provide enough information for use during pregnancy. Last, manufacturers of herbal products are not required to guarantee the reliability of the contents

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.

The nurse is administering medications to the patient who is in renal failure resulting from end-stage renal disease. The nurse is aware that patients with kidney failure would most likely have problems with which pharmacokinetic phase? a. Absorption b. Distribution c. Metabolism d. Excretion

ANS: D The kidneys are the organs that are most responsible for drug excretion. Renal function does not affect the absorption and distribution of a drug. Renal function may affect metabolism of drugs to a small extent.

Just before the second course of chemotherapy, the laboratory calls to report that the patient's neutrophil count is 450 cells/mm3. The nurse expects that the oncologist will follow which course of treatment? a. Chemotherapy will continue as scheduled. b. Chemotherapy will resume with a lowered dosage. c. Chemotherapy will resume after a transfusion of neutrophils. d. Chemotherapy will be withheld until the neutrophil count returns toward normal levels.

The nurse is reviewing new postoperative orders and notes that the order reads, "Give hydroxyzine (Vistaril) 50 mg IV PRN nausea or vomiting." The patient is complaining of slight nausea. Which action by the nurse is correct at this time? a. Hold the dose until the patient complains of severe nausea. b. Give the dose orally instead of intravenously. c. Give the patient the IV dose of hydroxyzine as ordered. d. Call the prescriber to question the route that is ordered.

ANS: D The nurse needs to question the route. Hydroxyzine (Vistaril) is an antihistamine-class antiemetic that is only to be given either by oral or intramuscular routes. It may be easy to make the mistake of giving hydroxyzine intravenously because many other antiemetics are given by that route. It is important to note that intravenous, intra-arterial, or subcutaneous administration of hydroxyzine may result in significant tissue damage, thrombosis, and gangrene. The nurse cannot change the route of an ordered medication without a prescriber's order. Antiemetic drugs are best given before the patient's nausea become severe.

A patient is receiving her third course of 5-fluorouracil therapy and knows that stomatitis is a potential adverse effect of antineoplastic therapy.

"You need to increase your intake of foods containing fiber and citric acid." d. "Be sure to examine your mouth daily for bleeding, painful areas, and ulcerations."

ANS: D The symptoms of stomatitis consist of pain or burning in the mouth, difficulty swallowing, taste changes, viscous saliva, dryness, cracking, and fissures, with or without bleeding mucosa. Teach patients to avoid consuming foods containing citric acid and foods that are hot or spicy or high in fiber. Assessing stools is important but is not related to stomatitis, and aspirin must not be used during this therapy

A patient is taking intravenous aminophylline for a severe exacerbation of chronic obstructive pulmonary disease. The nurse will assess for which therapeutic response? a. Increased sputum production b. Increased heart rate c. Increased respiratory rate d. Increased ease of breathing

ANS: D The therapeutic effects of bronchodilating drugs such as xanthine derivatives include increased ease of breathing. The other responses are incorrect.

The patient has been taking an over-the-counter (OTC) acid-reducing drug because he has had "stomach problems" for several months. He tells the nurse that the medicine helps as long as he takes it, but once he stops it, the symptoms return. Which statement by the nurse is the best advice for this patient? a. "The over-the-counter drug has helped you, so you should continue to take it." b. "The over-the-counter dosage may not be strong enough. You should be taking prescription-strength for best effects." c. "For best results, you need to watch what you eat in addition to taking this drug." d. "Using this drug may relieve your symptoms, but it does not address the cause. You should be seen by your health care provider."

ANS: D The use of OTC drugs may postpone effective management of chronic disease states and may delay treatment of serious or life-threatening disorders because these drugs may relieve symptoms without necessarily addressing the cause of the disorder. The other options do not address the need to investigate the cause of the symptoms and are incorrect.

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

When given a scheduled morning medication, the patient states, "I haven't seen that pill before. Are you sure it's correct?" The nurse checks the medication administration record and verifies that it is listed. Which is the nurse's best response? a. "It's listed here on the medication sheet, so you should take it." b. "Go ahead and take it, and then I'll check with your doctor about it." c. "It wouldn't be listed here if it were not ordered for you!" d. "Let me check on the order first before you take it."

ANS: D When giving medications, the nurse should always listen to and honor any concerns or doubts expressed by the patient. If the patient doubts an order, the nurse should check the written order and/or check with the prescriber. The other options illustrate that the nurse is not listening to the patient's concerns.

When reviewing the mechanism of action of a specific drug, the nurse reads that the drug works by selective enzyme interaction. Which of these processes describes selective enzyme interaction? a. The drug alters cell membrane permeability. b. The drug's effectiveness within the cell walls of the target tissue is enhanced. c. The drug is attracted to a receptor on the cell wall, preventing an enzyme from binding to that receptor. d. The drug binds to an enzyme molecule and inhibits or enhances the enzyme's action with the normal target cell.

ANS: D With selective enzyme interaction, the drug attracts the enzymes to bind with the drug instead of allowing the enzymes to bind with their normal target cells. As a result, the target cells are protected from the action of the enzymes. This results in a drug effect. The actions described in the other options do not occur with selective enzyme interactions.
