A client has a prescription to take guaifenesin. The nurse determines that the client understands the proper administration of this medication if the client states that she or he will perform which action? a. Take the tablet with a full glass of water b. Take an extra dose if fever develops c. Decrease the amount of daily fluid intake d. Take the medication with meals only

A. Take the tablet with a full glass of water Guaifenesin is an expectorant and should be taken with a full glass of water to decrease the viscosity of secretions. Extra doses should not be taken. The client should contact the primary health care provider if the cough lasts longer than one week or is accompanied by fever, rash, sore throat, or persistent headache. Fluids are needed to decrease the viscosity of secretions. The medication does not need to be taken with meals.

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

a. A history of peptic ulcers 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.

A 14-year-old boy is taking tretinoin (Retin-A) for acne. Which statement will the nurse include when. teaching the client about this medication? a. "This drug may cause increased redness of your skin." b. "You should exfoliate your skin every other day when taking this medication." c. "To speed up the healing process get plenty of sunlight." d. "Avoid fast food because it is heavy in salt and saturated fats."

a. "This drug may cause increased redness of your skin." Tretinoin may cause increased redness and drying, and the patient needs to avoid weather extremes, ultraviolet light, and abrasive cleansers. Certain foods (including fast food) do not need to be avoided.

A female client will be starting therapy with oral isotretinoin (Amnesteem) as part of treatment for severe acne, and the nurse is providing teaching. Which teaching point will the nurse include in her teaching plan about isotretinoin? a. "You will have to use two contraceptive methods while on this drug." b. "You will have to avoid pregnancy for 2 weeks after taking this drug." c. "You must avoid sexual activity while on this drug." d. "If you are taking an oral contraceptive, you may take this drug."

a. "You will have to use two contraceptive methods while on this drug." It is now required that at least two contraceptive methods be used by sexually active women during and for 1 month after completion of therapy with isotretinoin. The other statements are incorrect.

Which information should the nurse teach the client who is prescribed fluticasone propionate (Flovent) inhaler? a. Advise the client to gargle after each administration. b. Instruct the client to use the inhaler on a PRN basis. c. Teach the client to check his or her forced expiratory volume daily d. Encourage the client not to use a spacer when using the inhaler.

a. Advise the client to gargle after each administration. Gargling after each administration will help decrease the development of oropharyngeal yeast infections. This medication is intended for preventive therapy, not for aborting an ongoing asthma attack, and they should not be taken on a PRN basis. A spacer, a device that attaches directly to the metered-dose inhaler, should be used because a spacer increases the delivery of the drug to the lungs and decreases deposition of the drug on the oropharyngeal mucosa. Forced expiratory volume is the single most useful test of lung function, but the instrument required is a spirometer, which is expensive, cumbersome, and not suited for home use.

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. Appetite suppression b. ADHD c. Neonatal apnea d. Narcolepsy e. Panic attacks f. Depression

a. Appetite suppression b. ADHD c. Neonatal apnea d. Narcolepsy 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.

While teaching the client about taking a new prescription of oral metronidazole (Flagyl), the nurse should include which of the following most significant elements? a. Avoid intake of alcoholic beverages b. Headache may accompany ingesting the drug c. Drug may cause constipation d. Drug may cause vaginal dryness

a. Avoid intake of alcoholic beverages Ingesting alcoholic beverages with Flagyl can result in exaggerated sympathomimetic signs/symptoms including GI distress.

When developing a written nursing care plan for a client receiving chemotherapy for treatment of cancer, the nurse writes, "Assess each voiding for hematuria." The administration of which type of chemotherapeutic agent would prompt the nurse to add this assessment? a. Cyclophosphamide b. Chlorambucil c. Bleomycin sulfate d. Vincristine

a. Cyclophosphamide Hemorrhagic cystitis is the characteristic adverse reaction of cyclophosphamide.

The health care provider prescribes the H2 antagonist famotidine, 20 mg PO in the morning and at bedtime. Which statement regarding the action of H2 antagonists offers the correct rationale for administering the medication at bedtime? a. Hydrochloric acid secreted during the night is blocked. b. The drug relaxes stomach muscles at night to reduce acid. c. Gastric acid secreted at night is buffered, preventing pepsin formation. d. Ingestion of the medication at night offers a sedative effect, promoting sleep.

a. Hydrochloric acid secreted during the night is blocked. It's a H2 blocker/H2 antagonists act on the parietal cells to inhibit gastric secretion. Some gastric secretion occurs all the time, even when the stomach is empty, unless medications are taken to inhibit this action. It does not relax stomach muscles and it does not offer a sedative effect; these are not actions of famotidine. Buffering gastric acid is the action of antacids. Antacids do not affect healing or prevent the recurrence of ulcers; they merely provide symptomatic relief. Knowing the difference between H2 antagonists and antacids is important when teaching clients.

When a patient is receiving diuretic therapy, which of these assessment measures would best reflect the patient's fluid volume status? a. Intake, output, and daily weight b. Measurements of abdominal girth and calf circumference c. BP and pulse d. Serum potassium and sodium levels

a. Intake, output, and daily weight Intake, output, and daily weights are the best assessment measures to monitor a patient's fluid volume.

A client begins taking an atypical antipsychotic medication. The nurse must provide informed consent and education about common medication side effects. Which client education will be most important? a. Maintain a balanced diet and adequate exercise. b. Report any unusual facial movements. c. Monitor for any changes in sleep pattern. d. Be sure that the diet is adequate in salt intake.

a. Maintain a balanced diet and adequate exercise. Several atypical antipsychotic medications can cause significant weight gain, so the client should be advised to maintain a balanced diet and adequate exercise. Salt intake is important with lithium, a mood stabilizer. The other options are less common than weight gain.

The nurse is assessing a stuporous client in the emergency department who is suspected of overdosing with opioids. Which agent should the nurse prepare to administer if the client becomes comatose? a. Naloxone b. Atropine sulfate c. Flumazenil d. Vitamin K

a. Naloxone Naloxone is an opioid antidote used in opioid overdose to reverse CNS and respiratory depression. Atropine is used for bradycardia, intestinal hypertonicity and hypermotility, muscarinic agonist poisoning, peptic ulcer disease, and biliary colic. Vitamin K is used to manage warfarin overdose and vitamin K deficiency in newborns. Flumazenil reduces the sedative effects of benzodiazepines following general anesthesia or overdose.

A client with metastatic cancer who has been receiving fentanyl for several weeks reports to the nurse that the medication is not effectively controlling the pain. Which action should the nurse initiate? a. Notify the health care provider of the need to increase the dose. b. Administer naloxone per PRN protocol for reversal. c. Monitor the client for symptoms of opioid withdrawal. d. Instruct the client about the indications of opioid dependence.

a. Notify the health care provider of the need to increase the dose. Clients can develop a tolerance to the analgesic effect of opioids and may require an increased dose for effective long-term pain relief. The client is not exhibiting indications of dependence, withdrawal, or toxicity.

The nurse assesses for which most common side effect in a client with tuberculosis taking isoniazid (INH)? a. Paresthesia in limbs b. Non-adherence c. GI disturbances d. Ototoxicity

a. Paresthesia in limbs The most common adverse effect of associated with isoniazid is peripheral neuritis manifested as paresthesia of the extremities.

A woman has been receiving both radiation and chemotherapy for her cancer. Lately, she has developed anorexia caused by the treatments, so she needs short-term nutrition supplementation. The nurse anticipates that the physician will initiate which therapy? a. Peripheral parenteral nutrition b. Oral nutritional supplements with meals c. Central total parenteral nutrition d. Nasogastric enteral supplementation

a. Peripheral parenteral nutrition Patients receiving radiation and chemotherapy often experience anorexia secondary to nausea/vomiting and lack of appetite. Because of this condition the patient needs supplemental nutrition that bypasses the enteral system, so peripheral parenteral nutrition is the optimal intervention.

After being diagnoses with open-cratered gastric ulcer, a 19-year-old female client starts crying and refuses to take the prescribed medication. The nurse should complete which of the following activities at this time. Select all that apply. a. Sit with client to allow her to express her feelings b. Ask client to ingest one dose of misoprostol (Cytotec) c. Teach client about misoprostol (Cytotec) d. Teach client about ranitidine (Zantac) e. Explain risks associated with not treating an open-crater gastric ulcer

a. Sit with client to allow her to express her feelings e. Explain risks associated with not treating an open-crater gastric ulcer Discussion of feelings with another person helps the client manage emotional reactions. The nurse does not know why the client is crying. Although the client is emotionally upset, the nurse is obligated to inform the client of the risks associated with current behavior. Therefore options 2 & 4 are correct, the other options are not.

A patient will be taking oral iron supplements at home. The nurse will include which statements in the teaching plan for this patient? (Select all that apply.) a. Take the iron tablets with meals to reduce GI upset. b. Take the iron tablets on an empty stomach 1 hour before meals. c. Stools may become black and tarry. d. Drink 8 ounces of milk with each iron dose. e. Taking iron supplements with orange juice enhances iron absorption.

a. Take the iron tablets with meals to reduce GI upset. c. Stools may become black and tarry. e. Taking iron supplements with orange juice enhances iron absorption. Iron tablets need to be taken with meals to reduce gastrointestinal distress, but antacids and milk interfere with absorption. Orange juice enhances the absorption of iron. Stools may become black and tarry in patients who are on iron supplements. Tablets need to be taken whole, not crushed, and the patient needs to be encouraged to eat foods high in iron. Iron tablets need to be taken with meals to reduce gastrointestinal distress, but antacids and milk interfere with absorption. Orange juice enhances the absorption of iron. Stools may become black and tarry in patients who are on iron supplements. Tablets need to be taken whole, not crushed, and the patient needs to be encouraged to eat foods high in iron.

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 corticosteroid reduces the inflammation and itching associated with ear infections. b. The combination works to help soften and eliminate cerumen. c. The drops help to eliminate fungal infections. d. The corticosteroid reduces pain associated with ear infections.

a. The corticosteroid reduces the inflammation and itching associated with ear infections. 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 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 high. c. Lithium is not usually monitored with blood levels. d. The lithium level is too low.

a. The lithium level is therapeutic. Desirable long-term maintenance lithium levels range between 0.6 and 1.2 mEq/L. The other responses are incorrect.

The nurse is discharging a client diagnosed with chronic obstructive pulmonary disease (COPD). Which discharge instructions should the nurse provide regarding the client's prescription for prednisone? a. The medication should never be abruptly discontinued b. Stop taking the prednisone if a noticeable weight gain occurs c. Take the prednisone on an empty stomach with a full glass of water d. If you miss a dose of the medication, take two tablets the next time

a. The medication should never be abruptly discontinued Prednisone, is not abruptly discontinued because cortisol (a glucocorticoid) is necessary to sustain life and the adrenal glands stop producing cortisol while the client is taking it. The medication must be tapered off to prevent life-threatening complications.

When the nurse teaches a client about the side effects of anticholinergic medication, what signs or symptoms should be included? a. Urinary retention, constipation, or dilated pupils b. Pupillary constriction, bronchoconstriction, or bradycardia c. Inability to obtain an erection, irregular heart rhythm d. Increased salivation, dysphagia, confusion, restlessness

a. Urinary retention, constipation, or dilated pupils Anticholinergic effects include drying of mucous membranes, dilated pupils, and decreased motility of the GI tract.

A nurse is about to administer albuterol (Ventolin HFA) 2 puff and budesonide (Pulmicort) 2 puff by metered dose inhaler. The nurse plans to administer this medication in which of the following ways? a. albuterol first then budesonide b. budesonide inhaler first then inhaler c. alternating with a single puff each, starting with albuterol d. alternating with a single puff each, starting with budesonide

a. albuterol first then budesonide The nurse should administer albuterol first, wait 2-5 minutes (unless otherwise instructed by the health care provider), then administer the budesonide.

The nurse will be giving ophthalmic drugs to a client with glaucoma. The nurse expects the health care provider to order which med intravenously to reduce intraocular pressure when other medications are not successful? a. Mannitol b. Tobramycin c. Bacitracin d. Ketorolac

a. mannitol (Osmitrol) 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.

Which patient-teaching instructions are appropriate for a patient taking an antidysrhythmic drug? (Select all that apply.) a. "The presence of a capsule in the stool should be reported to the physician immediately." b. "Do not chew or crush extended-release forms of medication." c. "Take the medications with an antacid if gastrointestinal distress occurs." d. "Limit or avoid the use of caffeine." e. "Take the medication with food if gastrointestinal distress occurs."

b. "Do not chew or crush extended-release forms of medication." d. "Limit or avoid the use of caffeine." e. "Take the medication with food if gastrointestinal distress occurs." Appropriate teaching instructions for a patient taking an antidysrhythmic drug include: do not chew or crush extended-release forms; if gastrointestinal distress occurs, take the drug with food; and limit or avoid the use of caffeine. Do not double medication doses or take medications with an antacid. The presence of a portion of a capsule or tablet in the stool is actually the wax matrix that carried the medication, which has been absorbed. The physician does not need to be notified.

Which statement indicates that client teaching regarding the administration of the chemotherapeutic agent daunorubicin has been effective? a. "I should use sunscreen when I spend time outdoors." b. "I expect my urine to be red for the next few days." c. "I will eat high-fiber foods and drink lots of water." d. "I should use an astringent mouthwash after every meal."

b. "I expect my urine to be red for the next few days." Daunorubicin causes the urine to turn red in color. Using astringent mouthwash after every meal is not recommended. Eating high-fiber foods and drinking a lot of water and using sunscreen when outside are interventions that promote general good health but are not specific to treatment with daunorubicin.

A client with gastroesophageal reflux disease (GERD) is taking metoclopramide (Reglan) as prescribed. What client statement tells the nurse that the medication teaching session was effective? a. "This drug will prevent or stop diarrhea from occurring." b. "The purpose of this drug is to increase GI motility." c. "This drug decreases the tone of the lower esophageal sphincter." d. "This drugs kills H. pylori organism that causes peptic ulcer disease."

b. "The purpose of this drug is to increase GI motility." Metoclopramide is a GI stimulant, increasing motility of the GI tract, shortening gastric emptying time, and thus reducing the risk of the esophagus being exposed to gastric contents.

After liquid tetracycline is ordered for a 2-year-old child, the charge nurse provides which most important instruction to the new graduate nurse who is administering the medication? a. "Have the client drink the dose through a straw." b. "Withhold the drug until I telephone the prescriber." c. "Monitor the client for diarrhea." d. "Administer with 8 ounces of milk."

b. "Withhold the drug until I telephone the prescriber." Because of the staining of teeth and potential for irreversible delayed growth, tetracylcine should not be administered to children younger than 8 years. Discoloration of the teeth is not caused by direct contact with the drug but by systemic absorption.

The nurse is preparing to transfuse a patient with a unit of packed red blood cells (PRBCs). Which intravenous solution is correct for use with the PRBC transfusion? a. 5% dextrose in lactated Ringer's solution (D5LR) b. 0.9% sodium chloride (NS) c. 5% dextrose in water (D5W) d. 5% dextrose in 0.45% sodium chloride

b. 0.9% sodium chloride (NS) 0.9% sodium chloride (NS) is the only solution to use when transfusion PRBCs.

The emergency department nurse is concerned a client may develop signs of alcohol withdrawal. What assessments will the nurse include when providing care to this client? (Select all that apply.) a. difficult to arouse b. Anxiety c. Irritability d. Tachycardia e. Tremors f. Hypotension

b. Anxiety c. Irritability d. Tachycardia e. Tremors The client will demonstrate hypertension and hyperalertness. The remaining symptoms are associated with alcohol withdrawal.

Which action is most important prior to administering this medication? a. Assess the client's oral mucosa. b. Have another nurse check the prescription. c. Assess the client's liver function test results. d. Monitor the client's intake and output.

b. Have another nurse check the prescription. Double-checking the prescription is an important intervention because death can occur from an overdose. This medication is administered weekly and in low doses for rheumatoid arthritis and should not be confused with administration of the drug as a chemotherapeutic agent. Assessing the client's liver function and monitoring the client's I's & O's are appropriate interventions for those who are receiving this drug, but they are not the most important interventions. Stomatitis is an expected side effect of this medication.

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. This drug will cause the same effects as the alcohol did, without the euphoric effects. b. He needs to know about the common over-the-counter substances that contain alcohol. c. He should not smoke cigarettes while on this drug. d. Mouthwashes and cough medicines that contain alcohol are safe because they are used in small amounts.

b. He needs to know about the common over-the-counter substances that contain alcohol. 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.

A 38-year-old man has come into the urgent care center with severe hip pain after falling from a ladder at work.

The 40-year-old patient who is to have a kidney stone removed b. The 82-year-old client who is to have gallbladder removal c. The 21-year-old patient who has never had surgery before d. The 35-year-old patient who stopped smoking 8 years ago

b. The 82-year-old client who is to have gallbladder removal The elderly patient is more affected by anesthesia than the young or middle-aged adult patient because of the effects of aging on the hepatic, cardiac, respiratory, and renal systems.

A client has been prescribed to take both a tetracycline and a sulfonamide drug. When providing client teaching, what priority information should the nurse give the client related to adverse drug effects? a. Avoid exposure to upper respiratory infections. b. Use protective measures when exposed to the sun. c. Report signs of jaundice immediately. d. Change position slowly to avoid orthostatic hypotension.

c. Can cause dependence Dependence can occur with excessive or prolonged use of stimulant laxatives, which means that if the drug is stopped, a client is likely to experience constipation. Stimulant laxatives are not all enteric-coated and do not cause bowel erosion or ulcerative colitis. Prolonged use could lead to hypokalemia, not hyperkalemia, as a result of loss of electrolytes and fluids.

The nurse is reviewing antiepileptic drug (AED) therapy. Which statements about AED therapy are accurate? (Select all that apply.) a. A dose may be skipped if the patient is experiencing adverse effects. b. AED therapy can be stopped when seizures are stopped. c. Consistent dosing is the key to controlling seizures. d. AED therapy is usually lifelong. e. Abruptly stopping AEDs may cause rebound seizure activity.

c. Consistent dosing is the key to controlling seizures. d. AED therapy is usually lifelong. e. Abruptly stopping AEDs may cause rebound seizure activity.

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

c. If the chest pain is not relieved after one tablet, call 911 immediately 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.

A patient is receiving thrombolytic therapy, and the nurse monitors the patient for adverse effects. What is the most common undesirable effect of thrombolytic therapy? a. Nausea and vomiting b. Dysrhythmias c. Internal and superficial bleeding d. Anaphylactic reactions

c. Internal and superficial bleeding Internal and superficial bleeding is the most common adverse effects of thrombolytic therapy.

While monitoring a patient who had surgery under general anesthesia 2 hours ago, the nurse notes a sudden elevation in body temperature. This finding may be an indication of which problem? a. Malignant hypertension b. Tachyphylaxis c. Malignant hyperthemia d. Postoperative infection

c. Malignant hyperthermia A sudden elevation in body temperature during the postoperative period may indicate the occurrence of malignant hyperthermia, a life-threatening emergency. The elevated temperature does not reflect the other problems listed.

A client asks the nurse why he has to take several chemotherapy agents at the same time. The nurse's response would be based on which principle? a. One medication will interact with another to reduce the incidence of side effects. b. The cost is decreased because the medications are administered at the same time. c. Multiple medications given together will attack the cancer cells at different levels. d. The more medications that can be given together, the shorter the treatment period.

c. Multiple medications given together will attack the cancer cells at different levels. Combination drug therapy is important because different drugs inhibit cancer cell growth at various phases of cellular replication. This makes each of the medications more effective. Medications are given together because this is a more effective method of treatment, not because of cost or to reduce the side effects.

A client with a history of seizure disorder is newly diagnosed with a gastric ulcers. The client has been seizure free since starting phenytoin therapy. The nurse would question a new order for which of the following medications to treat symptoms caused by the ulcer? a. Misoprostol (Cytotec) b. Calcium carbonate (Tums) c. Omeprazole (Prilosec) d. Famotidine (Pepcid)

c. Omeprazole (Prilosec) Omeprazole is a proton pump inhibitor (PPI). PPIs may increase serum levels of phenytoin.

The nurse is preparing to administer a new order for eardrops. Which is a potential contraindication to the use of many otic preparations? a. Staphylococcus aureus otitis externa infection b. Escherichia coli ear infection c. Perforated eardrum d. Ear canal itching

c. Perforated eardrum While some antibiotics can be used when an eardrum is perforated, neomycin, polymyxin B, and hydrocortisone otic preparations are contraindicated in patients with a perforated eardrum. Be sure to clarify whether the drug can be given if a perforated eardrum is present. The other options are potential indications for eardrops.

A patient with elevated lipid levels has a new prescription for nicotinic acid (niacin). The nurse informs the patient that which adverse effects may occur with this medication? a. Myalgia, fatigue b. blurred vision, headaches c. Pruritus, cutaneous flushing d. Tinnitus, odorous urine

An 80-year-old client who had a colon resection yesterday is receiving a constant dose of hydromorphone via a patient-controlled analgesia (PCA) pump. Which finding requires immediate nursing action? a. Pupils are 3 mm; PERRLA. b. The client is drowsy and complains of pruritus. c. Respirations decrease to 10 breaths/min. d. The area around the sutures is reddened and swollen.

c. Respirations decrease to 10 breaths/min. Hydromorphone is an opioid agonist-analgesic of opiate receptors that inhibits ascending pathways and can cause respiratory depression. Older adults are more sensitive to opioids so the "start low and go slow" approach should be taken. Drowsiness and pruritus are common side effects of opioids, particularly the opiates, which are usually harmless and often transient. Pupils that are 3 mm are within the normal range (2 to 6 cm). The suture site may be red and swollen as an inflammatory response, but no action is required if the skin around the incision is a normal color and temperature.

After a family member reported altered mental status in a client with end-stage liver disease, the health care provided prescribed lactulose (Cephulac) 30 ml PO TID. The home health nurse reviews the client's chart for which laboratory test(s) to monitor medication effectiveness? a. Blood urea nitrogen & creatinine b. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) c. Serum Ammonia levels d. Bilirubin and urobilinogen

c. Serum Ammonia levels Elevated serum ammonia levels are commonly associated with hepatic encephalopathy which presents as altered mental status. Lactulose is a laxative that binds ammonia and makes it easier to excrete via feces. By monitoring serum ammonia levels, the nurse can monitor the effectiveness of the lactulose therapy.

What is the most important assessment data to consider before the nurse administers a dose of morphine sulfate to the patient? a. The client's pulse rate b. The appearance of the incision c. The client's respiratory rate d. The date of the client's last bowel movement

c. The client's respiratory rate 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.

During a routine appointment, a client 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 client's seizures should be under control because this is a therapeutic drug level. b. The client's seizures should be under control if she is also taking a second antiepileptic drug. c. The drug level is at a toxic level, and the dosage needs to be reduced. d. The client is at risk for seizures because the drug level is not at a therapeutic level.

c. The drug level is at a toxic level, and the dosage needs to be reduced. Therapeutic drug levels for phenytoin are usually 10 to 20 mcg/mL (see Table 14-6). The other options are incorrect.

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

d. Carbidopa prevents the breakdown of levodopa in the periphery. 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.

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. Nausea & vomiting b. HTN c. Hyperkalemia d. Cardiac dysrhythmias

Which laboratory finding is most important for the nurse to report to the health care provider? a. Serum potassium level of 5 mEq/L b. White blood cell count of 5000 mm3 c. Hemoglobin of 10.8 g/dL d. Hematocrit (HCT) of 58%

d. Hematocrit (HCT) of 58% A hematocrit (HCT) of 58% should be reported to the health care provider immediately because of the likelihood of a hypertensive crisis and because seizure activity increases with an increase in HCT of more than 4 points, or an HCT above 36%. Epoetin alfa stimulates erythropoiesis (production of red blood cells), thereby decreasing the need for blood transfusions. Uncontrolled hypertension can occur if erythropoietin levels are too high.

Zafirlukast is prescribed for a client with bronchial asthma. Which laboratory test does the nurse expect to be prescribed before the administration of this medication? a. Neutrophil count b. CBC c. Platelet count d. Liver function tests

d. Liver function tests Zafirlukast is a leukotriene receptor antagonists used in the prophylaxis and long-term treatment of bronchial asthma. Zafirlukast is used in caution in clients with impaired hepatic function. Liver function laboratory tests should be performed to obtain a baseline, and the levels should be monitored during administration of the medication. It is not necessary to perform the other laboratory tests before administration of the medication.

A 4-year-old child is receiving chemotherapy for acute lymphocytic leukemia. Which laboratory result should the nurse examine to assess the child's risk for infection? a. Lymphocyte count b. Platelet count c. Reticulocyte count d. Neutrophil count

d. Neutrophil count During chemotherapy, granulocytes are significantly suppressed. Because neutrophils comprise 60% to 70% of the granulocyte count, these levels are the most useful laboratory results of the options presented to determine the child's risk for infection. The platelet, reticulocyte, and lymphocyte counts are not as useful as neutrophil counts in determining risk of infection.

The nurse is reviewing the orders for a patient and notes a new order for an angiotensin-converting enzyme (ACE) inhibitor. The nurse checks the current medication orders, knowing that this drug class may have a serious interaction with what other drug class? a. Nitrates b. Diuretics c. Calcium channel blockers d.
