Rationale: Thrombocytopenia, a decrease in platelet count, is a known adverse effect associated with heparin therapy.

Rationale: Levothyroxine should be taken first thing in the morning before eating to ensure optimal absorption. Taking it on an empty stomach helps prevent interactions with food or other medications that may decrease its effectiveness. It is important to follow this timing recommendation to maintain consistent thyroid hormone levels in the body. Choice B is incorrect as taking Levothyroxine at bedtime may lead to inconsistent absorption and affect its efficacy. Choice C is incorrect because taking Levothyroxine with food can interfere with its absorption. Choice D is incorrect as Levothyroxine should be taken with a full glass of water, not milk, to aid in proper absorption.

Correct Answer: B

Rationale: Senna is a stimulant laxative commonly used to treat constipation by stimulating bowel movements. It is typically indicated for patients who have not passed stool in several days, thereby helping to relieve constipation. Patients with eating disorders may require different treatments related to their condition. Patients with anal fissures or a history of hemorrhoids may need treatments targeted at those specific issues, which may not involve Senna.

Correct Answer: A

Rationale: Clients prescribed Digoxin should monitor their heart rate before each dose. This is essential to identify any potential bradycardia, defined as a heart rate below 60 bpm, which can be a side effect of Digoxin. Any significant changes in heart rate should be reported promptly to the healthcare provider for further evaluation and management. Choice B is incorrect because increasing intake of high-potassium foods can lead to hyperkalemia, a condition that can be exacerbated by Digoxin. Choice C is incorrect as taking Digoxin with a full glass of milk is not necessary. Choice D is incorrect as black, tarry stools are not an expected side effect of Digoxin.
