ATI Capstone Pharmacology Assessment 2 Questions
Question 1 of 5
A patient with a new prescription for a HMG-CoA (statin) drug is instructed to take the
Correct Answer: D
Rationale: The nurse's best response is D: "This timeframe correlates better with the natural diurnal rhythm of cholesterol production." This explanation is accurate and helps the patient understand the rationale behind the timing of taking the HMG-CoA (statin) drug. Cholesterol production in the body typically follows a natural diurnal rhythm, with cholesterol synthesis peaking during the night. By taking the statin medication in the evening, it aligns with the body's cholesterol production pattern, making it more effective in reducing cholesterol levels. This explanation supports the patient's understanding of the importance of timing in maximizing the medication's effectiveness.
Question 2 of 5
The nurse is caring for a patient receiving IV heparin therapy for treatment of a pulmonary embolus. The patient is being converted to warfarin (Coumadin) therapy. The following questions relate nursing considerations when caring for this patient. Nursing considerations for conversion of IV heparin to oral warfarin (Coumadin) therapy will include
Correct Answer: B
Rationale: When converting a patient from IV heparin to oral warfarin (Coumadin) therapy, overlapping therapy of both medications for at least 5 days is typically recommended. This overlap ensures that the patient's blood remains appropriately anticoagulated during the transition period. The effectiveness of warfarin is delayed and it takes time for the INR to reach the therapeutic range; therefore, it is important to continue the IV heparin until the INR is within the desired range. Monitoring the INR is essential to adjust the dosages of warfarin accordingly and to ensure that the patient is receiving adequate anticoagulation therapy.
Question 3 of 5
The nurse is monitoring for adverse effects in a patient who is receiving an amiodarone
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Which of the following is a potassium-sparing diuretic?
Correct Answer: B
Rationale: Spironolactone is a potassium-sparing diuretic that works by blocking the effects of aldosterone in the distal tubules of the kidney, leading to increased excretion of sodium and water while retaining potassium. This class of diuretics helps to conserve potassium, making them suitable for patients at risk of hypokalemia. In contrast, furosemide, hydrochlorothiazide, and bumetanide are loop diuretics, thiazide diuretics, and another loop diuretic, respectively, which all promote the loss of potassium along with sodium and water.
Question 5 of 5
Select all the early manifestations of lithium
Correct Answer: A
Rationale: Nausea is one of the early manifestations of lithium toxicity. It is important to monitor for this symptom in patients taking lithium to detect toxicity early and prevent more serious complications. Hypotension and renal failure are more severe manifestations of lithium toxicity that occur at later stages. Muscle weakness is not typically associated with early lithium toxicity.
