A nurse is caring for a client who is receiving chemotherapy. The client's platelet count is 25,000/mm3. Which of the following actions should the nurse take?

Correct Answer: B

Rationale: Clients with a low platelet count are at risk of bleeding and infection. Monitoring the client's temperature every 4 hours is crucial to detect early signs of infection, as they may not be able to mount a typical immune response due to their compromised platelet count. Administering aspirin (choice A) is contraindicated in clients with low platelet counts as it can further increase the risk of bleeding. Monitoring urine output (choice C) and checking for stool in a colostomy bag (choice D) are important aspects of care but are not the priority in a client with low platelet count.

Correct Answer: A

Rationale: The correct answer is to monitor the INR (International Normalized Ratio) for a patient receiving warfarin therapy. INR monitoring is crucial to assess the effectiveness of warfarin in preventing blood clots while minimizing the risk of bleeding. Monitoring sodium levels (choice B), potassium levels (choice C), or platelet count (choice D) is not specifically essential for patients on warfarin therapy and does not provide direct information on the drug's anticoagulant effects.

Correct Answer: C

Rationale: The correct answer is C. Increasing the intake of saturated fats can raise cholesterol levels, which is not recommended after a myocardial infarction. Choices A, B, and D are all appropriate statements indicating a good understanding of post-myocardial infarction care. Taking a daily aspirin can help prevent another heart attack, experiencing chest pain with exercise is a common expectation post-myocardial infarction, and participating in a cardiac rehabilitation program is important for recovery and improving heart health.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid consuming alcohol while taking this medication.' Clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choice A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Choice C is incorrect as metformin is typically taken with meals, not at bedtime. Choice D is incorrect because muscle pain is not a common side effect of metformin.

Correct Answer: D

Rationale: The correct answer is D: 'Trim toenails straight across.' In clients with diabetes, trimming toenails straight across is important to prevent ingrown toenails, reducing the risk of infections. Soaking feet in warm water daily (choice A) can lead to dry skin and potentially cause skin breakdown in diabetic clients. While wearing cotton socks (choice B) is beneficial for good foot hygiene, it is not as crucial as trimming toenails correctly. Applying lotion to feet after bathing (choice C) is helpful for moisturizing the skin, but the emphasis should be on nail care to prevent complications like ingrown toenails.

Correct Answer: B

Rationale: The correct intervention for a client with nonblanchable erythema over the ischium is to teach the client to shift his weight every 15 minutes while sitting. This action helps relieve pressure on the affected area and prevents further skin breakdown. Placing the client upright on a donut-shaped cushion (Choice A) may not address the need for frequent weight shifts. Turning and repositioning the client every 3 hours (Choice C) is important for overall skin health but may not provide adequate relief for the specific area of nonblanchable erythema. Assessing pressure points every 24 hours (Choice D) is not frequent enough to prevent worsening of the skin condition in this case.

Correct Answer: B

Rationale: The correct answer is B because spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium. Instructing the client to avoid foods high in potassium helps prevent hyperkalemia, a potential side effect of spironolactone. Choice A is incorrect because taking spironolactone with a potassium supplement can increase the risk of hyperkalemia. Choice C is not directly related to spironolactone use. Choice D is also incorrect as spironolactone does not need to be taken on an empty stomach.

Correct Answer: C

Rationale: In clients with Cushing's syndrome, the nurse should expect hyperkalemia. Cushing's syndrome is characterized by excess cortisol levels, which can lead to potassium retention and result in hyperkalemia. Choices A, B, and D are incorrect. Hypotension is not typically associated with Cushing's syndrome; instead, hypertension is more common due to the effects of cortisol. Weight gain, rather than weight loss, is a common symptom of Cushing's syndrome. Hypercalcemia is not a typical finding in Cushing's syndrome; instead, hypocalcemia may occur due to increased urinary calcium excretion.

Correct Answer: C

Rationale: The correct answer is C: Broiled skinless chicken breast with brown rice. This option is suitable for a client with chronic pancreatitis as it is a low-fat, high-protein meal. Clients with pancreatitis should avoid high-fat foods like creamer, margarine, and avocados, making options A, B, and D incorrect choices.
