Correct Answer: B

Rationale: The correct answer is B: Antiplatelet. Aspirin works by inhibiting platelet aggregation, making it an antiplatelet agent. This effect helps reduce the risk of blood clot formation in clients with CAD. Choice A, Analgesic, is incorrect because aspirin's primary action in this context is not pain relief. Choice C, Anticoagulant, is incorrect as aspirin does not directly inhibit coagulation factors. Choice D, Thrombolytic, is incorrect as aspirin does not actively break down clots but rather prevents their formation.

Correct Answer: B

Rationale: Administering insulin as prescribed before meals is crucial for managing diabetes. This instruction is vital as it helps the client maintain blood sugar levels within the target range. Checking blood sugar levels once daily is important but not as critical as ensuring the timely administration of insulin. Taking medication only when feeling unwell is dangerous as it may lead to uncontrolled blood sugar levels. Eating carbohydrate-rich meals may actually destabilize blood sugar levels rather than stabilizing them, making it an incorrect choice.

Correct Answer: A

Rationale: Ethics is the correct answer because it specifically deals with the study of conduct and character. Ethics is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. While justice and morals are related to ethical considerations, they do not directly represent the study of conduct and character. Non-maleficence is a principle in medical ethics related to avoiding harm.

Correct Answer: C

Rationale: The correct answer is C: 'Lack of sleep.' In a client experiencing acute mania due to bipolar disorder, lack of sleep is the priority finding for the nurse to address. Sleep deprivation can exacerbate symptoms, lead to exhaustion, and increase the risk of further complications. Pressured speech, increased appetite, and mood swings are also common in acute mania, but addressing the lack of sleep takes precedence due to its significant impact on the client's well-being and recovery.

Correct Answer: B

Rationale: The most appropriate intervention for constipation is to encourage the client to increase dietary fiber intake. Fiber helps promote bowel movements and relieve constipation by adding bulk to the stool. Administering a laxative (Choice A) should not be the first-line intervention as it can lead to dependence. Encouraging rest (Choice C) is not directly helpful in relieving constipation. While administering a stool softener (Choice D) can be beneficial, increasing fiber intake is generally preferred as the initial intervention.
