A client is prescribed linsinopril. Which of the following findings indicates to the nurse that the client is experiencing an adverse effect of this medication? a. Serum potassium 5.8 mEq/L b. Fasting blood glucose 40 mg/dl c. Creatine kinase (CK) 120 units/L d. White blood cell count 10,000mm3
a. Serum potassium 5.8 mEq/L Serum potassium 5.8 mEq/L is the correct answer. ACE inhibitors may cause hyperkalemia. Suppression of angiotensin II leads to a decrease in aldosterone levels. Since aldosterone is responsible for increasing the excretion of potassium, ACE inhibitors can lead to elevated serum potassium. The nurse should monitor potassium levels to maintain normal range of 3.5 - 5.0 mEq/L.
A client diagnosed with depression has been prescribed fluoxetine. Which of the following information should the nurse emphasize? a. Take the medication in the morning b. Take the medication at bedtime c. Maintain an adequate fluid and sodium balance d. Avoid foods high in tyramine
a. Take the medication in the morning Take the medication in the morning, as insomnia is a side effect of SSRIs.
A nurse is caring for a client who is prescribed gentamicin sulfate. Which of the following side effects would indicate an adverse reaction to this medication? a. Urinary output of 185 mL in an 8 hour shift. b. Muscular cramping in the lower extremities. c. Pruritis in the forearms and upper arms. d. Fine tremors in the fingers and hands.
a. Urinary output of 185 mL in an 8 hour shift. Urinary Output of 185 mL in an 8 hour period could indicate nephrotoxicity which is an adverse side effect of an aminoglycosides. Normal urinary output should be at least 30 mL per hour to adequately remove waste products from the body.
A nurse is evaluating a client's understanding of lithium. Which statement by the client indicates a need for further education? a. "I will drink 8-12 glasses of water a day." b. "I should take the medication on an empty stomach." c. "I should have my blood level drawn as directed." d. "I will contact my provider if I develop diarrhea."
b. "I should take the medication on an empty stomach." Lithium should be taken with meals or milk to decrease gastric upset.
A nurse is reinforcing teaching with a client about the adverse effects of levodopa. Which client statement would indicate to the nurse that further instructions is needed? a. "I will not eat bananas." b. "I still can drive." c. "I will administer the medication with food." d. "I will get out of bed slowly."
b. "I still can drive." Correct: This medication may cause sudden onset of sleep, drowsiness and dizziness. Instruct client to avoid driving and other activities that required alertness.
A client has been prescribed spironolactone for treatment of heart failure. Which statement made by the client would indicate a need for further reinforcement of teaching? a. "I will need to have routine labs drawn while taking this medication." b. "I will limit the use of salt in my diet and use a salt substitute instead." c. "I will weigh myself daily and report any changes in weight." d. "I should take my medication at the same time each day in the morning."
b. "I will limit the use of salt in my diet and use a salt substitute instead." Correct: Spironolactone is a potassium sparing diuretic and caution should be taken when using this medication with anything that may increase potassium levels. Most salt substitutes contain potassium and should be avoided. Clients should also never take an oral potassium substitute, and be cautioned about large dietary changes that increase potassium. ACE inhibitors should also be used with cautions when on a potassium sparing diuretic.
A client is prescribed digoxin. Which of the following statements by the client indicates to the nurse the need for further teaching? a. "I will check my pulse every day before taking my medication." b. "If I see halos around lights there is no need to notify my provider." c. "I should eat bananas and drink orange juice when I am on this medication." d. "I will take my medication at the same time each day."
b. "If I see halos around lights there is no need to notify my provider." CNS effects such as blurred vision, diplopia and white halos around objects are a sign of drug toxicity and client should notify provider immediately.
A client has an order for an IV of 1000 ml of lactated ringers with 20 mEq of potassium/L to infuse at 40 ml/hr. The drip factor is 15 drops/ml. The nurse calculates the flow rate to be: ______ gtt/min. . 9 drops/min b. 10 drops/min c. 11 drops/min d. 12 drops/min
b. 10 drops/min ml/hr X drops/ml 40 ml/hr X 15 drops/ml time in mins 60 mins

Digoxin level of 0.5 ng/ml b. Potassium level of 3.4 mEq/l c. Calcium level of 11mg/dl d. Sodium level of 133 mEq/l
b. Potassium level of 3.4 mEq/l Serum potassium is important to monitor for the client on digoxin. Hypokalemia can lead to digoxin toxicity while hyperkalemia can lead to a low therapeutic level. The normal range for potassium is 3.5-5.0 mEq/l.
A client with Type 1 diabetes has the following values from the morning laboratory testing: fasting plasma glucose = 115 mg/dL and HgA1C = 7.5%. How would a nurse interpret these values with regard to the client's glucose control? a. Short term values elevated, long-term values normal b. Short term values normal, long-term values elevated c. Short term values elevated, long term values elevated d. Short term values normal, long term values norm
b. Short term values normal, long-term values elevated Fasting plasma glucose is normal. Normal fasting plasma glucose range for the diabetic client is 90-130 mg/dl. HgA1C level is elevated. HgA1C normal level range is less than 7% with the optimal range being 4-6% in the diabetic. HgA1C level indicates the client's glucose range over the last 120 day period and is considered to be the best indicator of long term glycemic control
A nurse is caring for a client receiving total parenteral nutrition (TPN). Which of the following outcomes best demonstrates that TPN therapy is effective? a. The client reports less frequent bowel movements. b. The client maintains an albumin level of 5.0 g/100mL. c. The client's urinary output increases by 800 mL per day. d. The client gains one kilogram per day
b. The client maintains an albumin level of 5.0 g/100mL. When clients are on TPN therapy, laboratory values such as electrolytes, CBC, BUN, and plasma glucose should be monitored closely. All laboratory values should be within normal range. Normal range for albumin
A nurse is caring for a client with a history of rheumatoid arthritis who is receiving methotrexate. Which of the following should be included in client education? a. Daily monitoring of blood glucose is recommended b. The complete blood count (CBC) will be monitored. c. Methotrexate can be administered during pregnancy d. Methotrexate will decrease the risk of developing cancer.
b. The complete blood count (CBC) will be monitored. Bone marrow suppression is a common side effect when using methotrexate for long term therapy in the treatment of rheumatoid arthritis. The client will have their complete blood count monitored periodically for evidence of anemia, neutropenia or thrombocytopenia.
A nurse is caring for a client taking captopril. Which finding would require immediate attention for this client? a. Sodium 133 b. Potassium 5.8 c. Blood pressure 96/48 d. Pulse 56
b. potassium of 5.8 is elevated- normal is 3.5-5. One effect of captopril is elevation of potassium levels because this drug inhibits the formation of angiotensin II and blocks the release of aldosterone. The blocking of the aldosterone results in sodium excretion and potassium retention. Hyperkalemia can result in cardiac arrhythmias and if untreated lead to cardiac arrest.
A client ingested a full bottle of imipramine hydrochloride. Which of the following toxic effects is most important for the nurse monitor? a. Hypertension b. Photophobia c. Arrhythmias d. Blurred vision
c. Arrhythmias With a Tricyclic antidepressant (TCA) overdose, there is a high risk for serious cardiac problems, including arrhythmias, tachycardia and myocardial infarction.
A client is admitted to the hospital with a diagnosis of diabetic ketoacidosis (DKA). An intravenous infusion of regular insulin has been started. Which of the following nursing interventions is most appropriate for this client? a. Obtain an arterial blood gas every 2 hours b. Monitor blood glucose levels every 4 hours c. Ensure glucagon is readily available d. Add the prescribed dose of NPH insulin to the IV infusion
c. Ensure glucagon is readily available Glucagon and D50 are used for rapid treatment of hypoglycemia which can occur when insulin is administered intravenously
During administration of vancomycin IV, the nurse notices the client's neck and face becoming flushed. Which of the following actions should the nurse take first? a. Check the client's temperature. b. Obtain an order for an antihistamine. c. Slow the rate of the infusion. d. Notify the health care provider.
c. Slow the rate of the infusion. Flushing of the face and neck are minor symptoms of red man or red neck syndrome occurring with too rapid infusion of Vancomycin. Vancomycin can cause two types of hypersensitivity reactions, the red man syndrome and anaphylaxis. Red man syndrome has often been associated with rapid infusion of the first dose of the drug and was initially attributed to impurities found in vancomycin preparations. Slowing the rate of infusion can help symptoms to resolve. The client should be monitored for serious reactions such as hypotension, dyspnea, anaphylaxis, renal failure or hearing loss. Other minor reactions are chills, dizziness, fever, pruritis, and tinnitus
A client with a digoxin level of 2.4 ng/ml has a heart rate of 39. The health care provider prescribes atropine sulfate. Which of the following best describes the intended action of atropine for this client? a. To reduce peristalsis and urinary bladder tone. b. To stimulate the SA node and sympathetic fibers to increase the rate c. To accelerate the heart rate by interfering with vagal impulses d. To dry oral and tracheobronchial secretions.
c. To accelerate the heart rate by interfering with vagal impulses. Atropine accelerates the heart rate by interfering with vagal impulses. It is given IVP at doses of 0.5mg to 1.0mg per dose; every 3 to 5 minutes; up to 2.0mg. Doses less than 0.5mg may cause a paradoxical slowing of the heart rate. When Atropine is given to a client with history of an MI it should be used with great caution; increasing the heart rate also increases myocardial oxygen consumption!
A nurse is to administer nitroglycerin to a client for the treatment of angina. Which of the following should the nurse first advise the client? a. A headache may occur. b. Dizziness may occur. c. To sit or lie down. d. To rise slowly
c. To sit or lie down. Inform client to sit or lie down. This intervention is priority due to the orthostatic hypotension effects that can occur with nitroglycerin administration; including dizziness, light-headedness, and reduced cardiac output. This can cause a drop in blood pressure. Lying with feet elevated promotes venous return and thereby restores blood pressure. This is a safety concern and action needs to be taken before medication administration
A client is prescribed phenytoin 5 mg/kg/day in 3 divided doses. The client weighs 36 lb. The drug is available at 50mg/mL. What is the total daily dosage in milliliters for this client? a. 0.5 mL b. 2.6 mL c. 7.8 mL d. 1.6 mL
d. 1.6 mL 36 /2.2=16.4kg5 X 16.4 = 82 mg/day82/50=1.64 mL/day
A client with a recent myocardial infarction is prescribed digoxin. Which of the following findings indicate to the nurse that a therapeutic response to this medication has been attained? a. An increase in apical pulse rate. b. A decrease in urinary output. c. A rise in central venous pressure. d. A decrease in pulmonary crackles.
d. A decrease in pulmonary crackles. Heart failure exists to some degree in all clients with myocardial infarction. Crackles would be present due to left-sided failure and passive reflux of blood leading to pulmonary hypertension. Digoxin increases the force of the systolic contraction which allows complete ventricular emptying and improved cardiac output. Pulmonary edema is thus reduced.
A client in the behavioral health unit began taking fluoxetine 20 mg per day three days ago for depression. Which of the following should the nurse immediately report to the health care provider? a. Weight gain b. Headache and nausea c. Sexual dysfunction d. Agitation and fever
d. Agitation and fever Agitation and fever are symptoms of serotonin syndrome, a potentially life-threatening condition that can develop in client's taking SSRIs such as fluoxetine. These symptoms develop within 2-72 hours after starting treatment and may also include mental confusion, anxiety, hallucinations, tremors, and hyperreflexia.
A client is a Jehovah's Witness and is scheduled for an elective hysterectomy secondary to prolonged and heavy menses. Which medication would the nurse anticipate being ordered prior to surgery for this client? a. Methylergonovine b. Interferon c. Retrovir d. Epoetin Alfa
d. Epoetin Alfa Correct: Epoetin Alfa is a growth factor used to treat anemia related to renal disease, chemotherapy, HIV / AIDS treatment and for clients who are anemic undergoing elective surgery. Jehovah's Witness' clients generally do not accept blood transfusions, and this client has had prolonged and heavy menstrual bleeding and is likely anemic. In this case, Epoetin Alfa dosing 2-4 weeks prior to surgery (generally once per week for four weeks prior to surgery) would be indicated to raise the hemoglobin to a therapeutic level.
A client diagnosed with bipolar disorder and prescribed lithium carbonate is being discharged from the hospital. Which of the following medication prescriptions should the nurse should question? a. Captopril 25 mg by mouth bid b. Valproic acid 250 mg by mouth tid c. Ranitidine 150 mg by mouth daily d. Furosemide 20 mg by mouth bid
d. Furosemide 20 mg by mouth bid The furosemide prescription should be questioned. Lithium ingestion predisposes the client to sodium loss which increase the risk of rapidly elevating level of lithium. Diuretics would exacerbate sodium loss and predispose the client to lithium toxicity.
A clinic nurse is preparing to administer a penicillin IM injection to a client who has never taken the medication before. Which of the following interventions should be included in the plan of care? a. Ask the client if they are allergic to shell fish before administering. b. Instruct the client to expect a slight rash to develop at the injection site. c. Inject the client with a small test dose of penicillin subcutaneously. d. Instruct the client to sit in the clinic for 30 minutes after the injection.
d. Instruct the client to sit in the clinic for 30 minutes after the injection. To ensure prompt treatment if anaphylaxis should develop, clients should remain in the prescriber's office for at least 30 minutes after drug injection. After 30 minutes, the risk of anaphylactic reaction is reduced.
A nurse is caring for a client taking captopril who has started experiencing a frequent dry cough. What action should the nurse take? a. Encourage the client to use over the counter cough syrup for the cough. b. Encourage the client to continue taking the medication as prescribed. c. Instruct the client to decrease the dosage of the medication. d. Notify the provider of the client's symptom.
d. Notify the provider of the client's symptom. An adverse effect of ACE inhibitors is a cough related to inhibition of kinase II which results in an increase in bradykinin. The provider should be notified if a dry cough occurs so that the medication can be discontinued.
A client experiences postural hypotension during initial drug therapy with diltiazem. Which of the following would be most important for the nurse to recommend to this client? a. Eat small, frequent meals during the day. b. Drink additional oral fluids each day. c. Lie down for 30 minutes after taking the medication. d. Rise slowly from a sitting or lying position.
d. Rise slowly from a sitting or lying position. Rise slowly from a sitting or lying position. This will allow them to adjust to the upright position; slowly rising allows the heart to adjust the cardiac output to pump harder to maintain adequate BP to offset any orthostatic hypotension from occurring.
A client is prescribed lisinopril. Which of the following is most important for the nurse to assess before administering this medication to the client? a. Breath sounds. b. Peripheral edema. c. Body temperature. d. Serum electrolytes. .
d. Serum electrolytes. A side effect of lisinopril is hyperkalemia. Hyperkalemia can lead to life threatening dysrhythmias. The nurse should monitor the client's serum K+ level closely and notify the provider of a critical level before administering an ACE inhibitor.
A nurse is caring for a client prescribed omeprazole. What information should the nurse provide to the client regarding administration of this medication? a. You may crush the medication for easier swallowing. b. Take the medication at bedtime. c. Take the medication after a meal twice daily. d. Take the medication in the morning before breakfast.
d. Take the medication in the morning before breakfast. Clients should take omeprazole once a day prior to eating in the morning.
A client diagnosed with preterm labor has been prescribed nifedipine. The client asks the nurse why this particular medication has been prescribed. Which of the following statements by the nurse is correct? a. To lower your blood pressure b. To promote development of your baby's lungs c. To decrease the intensity of your pain d. To relax your muscles of your uterus
d. To relax your muscles of your uterus The use of nifedipine for the treatment of preterm labor is an unlabeled use of the drug. Nifedipine, a calcium channel blocker, is more commonly used to treat high blood pressure and heart disease. Smooth muscle tissue, like the uterus, needs calcium to contract. Nifedipine blocks the passage of calcium into certain tissues, relaxing the uterine muscles and smooth muscles of blood vessels throughout the body.
A nurse is to administer morphine sulfate 10 mg intramuscular (IM) to an adult client for post-operative pain. Which injection site is the most appropriate? a. Deltoid b. Epidural c. Dorsogluteal d. Ventrogluteal
d. Ventrogluteal This site is a deep site, situated away from the major nerves and blood vessels. This site is preferred for medications (such as antibiotics) that are larger in volume, more viscous, and irritating for adults, children, and infants. This site is safe for all clients with large muscle development.
