ATI Pharmacology Proctored Exam

Correct Answer: A

Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can lead to hyperkalemia by inhibiting the action of aldosterone. Hyperkalemia is a potential adverse effect, making it essential for the nurse to closely monitor the client's potassium levels to prevent complications such as cardiac arrhythmias. Incorrect Options Rationale: - Option B, Hypoglycemia, is not a common adverse effect of Valsartan. - Option C, Bradycardia, is not typically associated with Valsartan use. - Option D, Hypercalcemia, is not a known adverse effect of Valsartan; instead, Valsartan can lead to hyperkalemia.

Correct Answer: B

Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, leading to potassium retention. Monitoring potassium levels is essential to prevent complications associated with hyperkalemia. Bradycardia (Choice A) is not a common adverse effect of Enalapril. Enalapril does not typically affect glucose levels, so hypoglycemia (Choice C) is not a common concern with this medication. Enalapril does not directly impact calcium levels, so hypocalcemia (Choice D) is not a typical adverse effect.

Correct Answer: A

Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.

Correct Answer: B

Rationale: The correct response is B: 'It can decrease the frequency of migraine headaches.' Feverfew is known for reducing the frequency of migraine headaches, but it has not been proven to relieve an existing migraine headache. Choices A, C, and D are incorrect because Feverfew is not used to treat skin infections, lessen nasal congestion in the common cold, or relieve nausea of morning sickness during pregnancy.

Correct Answer: C

Rationale: Jaundice is an adverse reaction that can occur in clients taking Gemfibrozil due to the potential development of liver impairment. Other symptoms of liver impairment may include anorexia and upper abdominal discomfort. Monitoring for signs of jaundice is crucial to detect and manage adverse effects of the medication promptly. Mental status changes (choice A) are not commonly associated with Gemfibrozil use. Tremor (choice B) is not a typical adverse reaction of Gemfibrozil. Pneumonia (choice D) is not directly linked to Gemfibrozil use but can be a complication in some cases.
