Correct Answer: A

Rationale: The correct answer is A: Lamb. Lamb is high in saturated fat, which is linked to an increased risk of developing cancer. Choice B (Poultry) is a lean protein source and is not associated with an increased cancer risk. Choice C (Tuna) is a good source of omega-3 fatty acids, which have anti-inflammatory properties that may reduce cancer risk. Choice D (Beef) is also high in saturated fat like lamb, making it a poor choice for cancer prevention.

Correct Answer: B

Rationale: The correct answer is B because the client should press the button when feeling fetal movement to track the baby's activity. Choice A is incorrect because the client should press the button during movements. Choice C is incorrect as the button should be pressed during fetal movements, not contractions. Choice D is irrelevant to the instructions for the nonstress test.

Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. In SIADH, there is excessive release of antidiuretic hormone, causing water retention and dilutional hyponatremia. Polyuria (choice A) is increased urination, which is not a typical finding in SIADH. Dehydration (choice B) is the loss of body fluids, which is opposite to the fluid retention seen in SIADH. Hyperglycemia (choice D) is elevated blood sugar levels and is not directly related to SIADH.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Rest as needed throughout the day.' Fatigue is a common symptom of multiple sclerosis (MS), and adequate rest is essential to manage it effectively. Resting as needed helps conserve energy and prevent fatigue from worsening. Choices A, C, and D are incorrect. 'Exercise to the point of exhaustion' is not recommended as it can lead to increased fatigue. 'Avoiding physical activity' entirely is not advisable as appropriate exercise can help maintain strength and energy levels. 'Exercising only once per week' may not be sufficient to combat fatigue and maintain overall well-being in clients with MS.

Correct Answer: A

Rationale: A WBC count of 2,900/mm3 indicates leukopenia, which is a serious side effect of clozapine and contraindicates its use. Leukopenia is a significant concern with clozapine therapy due to the risk of agranulocytosis, a potentially life-threatening condition. Monitoring the WBC count is crucial to detect this adverse effect early. The other options (B, C, and D) are within normal ranges and not contraindications for administering clozapine.
