ATI Pharmacology Proctored Exam

Correct Answer: A

Rationale: Corrected Rationale: Hydrochlorothiazide is a diuretic known to cause electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client for signs of hyponatremia by assessing their electrolyte levels. Choice B, Hyperkalemia, is incorrect as hydrochlorothiazide is more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia. Choice C, Hypercalcemia, is incorrect because hydrochlorothiazide is not known to cause increased calcium levels. Choice D, Hypoglycemia, is also incorrect as it is not a common adverse effect of hydrochlorothiazide.

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: A

Rationale: Clients taking Warfarin should avoid foods high in vitamin K, such as broccoli, as they can interfere with the effectiveness of the medication. Vitamin K can counteract the anticoagulant effects of Warfarin, potentially leading to blood clotting issues. Broccoli is rich in vitamin K, so its consumption should be consistent to avoid fluctuations in the medication's effectiveness. Bananas, chicken, and potatoes are not known to significantly interact with Warfarin and do not pose a risk of affecting its anticoagulant properties.

Correct Answer: A

Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that is most effective in reducing stomach acid production when taken before meals. This timing helps the medication work optimally by inhibiting acid secretion that occurs in response to food intake. Choice B ('Take this medication with food') is incorrect because Omeprazole should be taken before meals. Choice C ('Take this medication at bedtime') is incorrect as the optimal timing is before meals, not at bedtime. Choice D ('Take this medication with antacids') is incorrect because Omeprazole should not be taken with antacids as they can interfere with its absorption.

Correct Answer: A

Rationale: Corrected Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing potassium excretion through the kidneys. Monitoring serum potassium levels is crucial to detect hyperkalemia early and prevent adverse effects such as cardiac arrhythmias. Choices B, C, and D are incorrect because Lisinopril is not known to significantly impact sodium, calcium, or magnesium levels in the same way it affects potassium levels.
