ATI Pharmacology Proctored Exam

Correct Answer: A

Rationale: To calculate the dosage per administration: First, convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, calculate the required dosage per dose: (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. To determine the mL per dose, divide the required dosage by the concentration of the amoxicillin suspension: (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the correct answer is 4 mL. Choice B (5 mL) is incorrect because the correct calculation yields 4 mL. Choices C (6 mL) and D (3 mL) are also incorrect as they do not align with the accurate calculation based on the provided information.

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: A

Rationale: The correct instruction for a client prescribed Clopidogrel is to avoid taking aspirin while on this medication. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs can potentiate the risk of bleeding, so they should be avoided while taking Clopidogrel to prevent adverse effects. Choices B, C, and D are incorrect because Clopidogrel does not need to be taken with food, there is no specific dietary restriction related to potassium, and the timing of administration (bedtime) is not a critical instruction for this medication.

Correct Answer: A

Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that should be taken before meals to be most effective in reducing stomach acid production. Taking it before meals allows the medication to inhibit the proton pumps in the stomach when they are most active, leading to better control of acid secretion. Choice B is incorrect because taking Omeprazole with food may reduce its effectiveness as food can interfere with its absorption. Choice C is incorrect as Omeprazole is more effective when taken before meals. Choice D is incorrect as Omeprazole should not be taken with antacids as they can reduce its absorption.

Correct Answer: A

Rationale: The correct instruction for a client with a new prescription for nitroglycerin sublingual tablets is to take one tablet at the first sign of chest pain. If the pain is not relieved after 5 minutes, the client should call 911 and take a second tablet. Taking more than the recommended dose can lead to serious side effects, and swallowing the tablet would not provide the rapid effect needed in cases of chest pain. Choice A is correct because it aligns with the standard protocol for nitroglycerin use in treating angina. Choice B is incorrect as the second tablet should be taken after 5 minutes, not 10 minutes. Choice C is incorrect as taking up to five tablets in 15 minutes is excessive and can result in serious complications. Choice D is incorrect as nitroglycerin sublingual tablets should be placed under the tongue for rapid absorption, not swallowed.
