Results Displayed Feedback A nurse who provides care in a busy clinic is aware of the high incidence and prevalence of hyperlipidemia and the consequent need for antihyperlipidemics in many patients. Treatment of high cholesterol using statins would be contraindicated in which of the following patients? Response Feedback: Active liver disease is a contraindication to the use of statins. As well, heavy alcohol use increases the risk of liver dysfunction. Respiratory disease, recent surgery, and organic cognitive deficits do not preclude the use of statins for high cholesterol. A nurse is caring for a male patient who has a diagnosis of coronary artery disease (CAD). His drug therapy includes lovastatin. Because the patient has a history of severe renal disease, the nurse will assess for which of the following? Response Feedback: Patients with severe renal disease may have an increased plasma concentration of lovastatin because 10% of the drug is eliminated in the urine. Patients with renal disorders are not likely to experience a decrease in LDL or an increase in the statin tolerance level. Which of the following patients is most likely to benefit from the administration of an adrenergic agonist? Response Feedback: One of the most frequent indications for adrenergic agonist drugs is shock. Their use is contraindicated in labor, and they would • Question 4 1 out of 1 points • Question 5 1 out of 1 points • Question 6 1 out of 1 points • Question 7 1 out of 1 points exacerbate hypertension. A nurse is caring for a patient who is diabetic and has been diagnosed with hypertension. An angiotensin-converting enzyme inhibitor, captopril, has been prescribed for her. Which of the following should the nurse assess before beginning drug therapy? Response Feedback: Captopril inhibits the angiotensin-converting enzyme that is needed to change the inactive angiotensin I to the active form, angiotensin II. This reduction of angiotensin II decreases the secretion of aldosterone, preventing sodium and water retention. This action decreases peripheral vascular resistance and lowers blood pressure. Serum potassium may increase as a result of decreased aldosterone levels. It would be helpful to have a baseline level at the beginning of the drug therapy to monitor the possible effect of hyperkalemia. There is no need to monitor calcium and magnesium levels. While it is important to always know a diabetic's blood glucose level, captopril does not alter the level during therapy. A nurse is the cardiac care unit is preparing to hang an intravenous dose of dofetilide (Tikosyn) for a patient who has just been admitted. What is the most likely goal of this intervention? Response Feedback: Dofetilide is used to convert patients in atrial fibrillation to normal sinus rhythm and maintain them in sinus rhythm. This drug is not used in the treatment of bradycardia, heart failure, or ventricular arrhythmias. [Show More]
