Correct Answer: A

Rationale: Clients prescribed Warfarin should avoid foods high in vitamin K, like broccoli, as they can counteract the medication's effectiveness. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming high vitamin K foods can interfere with its anticoagulant effects. Bananas, chicken, and potatoes are not high in vitamin K and do not have a significant impact on Warfarin therapy.

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.

Correct Answer: D

Rationale: The nurse should advise the client to limit aerobic activity in hot weather to prevent sodium/water depletion, which can increase the risk for Lithium toxicity. Excessive sweating and fluid loss can lead to dehydration and changes in lithium levels, potentially resulting in toxicity. Choices A, B, and C are incorrect. Avoiding acetaminophen for headaches is not directly related to Lithium toxicity. Restricting sodium intake and decreasing fluid intake can lead to increased lithium levels and toxicity, so these are not recommended actions.

Correct Answer: D

Rationale: Propranolol is contraindicated in clients with a first-degree heart block due to its negative chronotropic properties that can further slow the heart rate. This can worsen conduction through the atrioventricular node, potentially leading to heart block progression. Therefore, the nurse should report the finding of a first-degree heart block to the provider before initiating Propranolol therapy. Choices A, B, and C are not contraindications for Propranolol therapy. A prior myocardial infarction, taking warfarin for atrial fibrillation, or using an SSRI for depression do not directly impact the initiation of Propranolol therapy in a client with a history of migraine headaches.

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.
