Correct Answer: B

Rationale: The correct answer is B because shortness of breath is an indication of transplant rejection, along with other manifestations like fatigue, edema, bradycardia, and hypotension. Choice A is incorrect because immunosuppressant medications are usually taken for life to prevent rejection. Choice C is incorrect as the surgical site may take longer to heal fully. Choice D is incorrect as the initiation of exercise post-heart transplant should be gradual and individualized based on the client's condition.

Rationale: Tuberculosis is spread through small droplets, measuring less than 5 microns, which can remain airborne for extended periods. The nurse should place a client with TB under airborne precautions to prevent the transmission of the disease. Choice A, contact precautions, are used for diseases that spread by direct or indirect contact. Choice C, droplet precautions, are for diseases transmitted by large droplets. Choice D, protective environment, is used for clients who have compromised immune systems.

Correct Answer: A

Rationale: The correct answer is A: "I don't have muscle spasms as frequently." The nurse should identify that dantrolene relaxes skeletal muscles, so a decrease in muscle spasms indicates the medication is effective. Choice B is incorrect as cold prevention is not related to dantrolene. Choice C is incorrect because nerve pain improvement is not a direct effect of dantrolene. Choice D is incorrect as dantrolene's action does not affect urination.

Correct Answer: B

Rationale: The correct answer is B: "Increase intake of high-potassium foods." Furosemide is a loop diuretic that can lead to hypokalemia, a condition characterized by low potassium levels. To prevent this adverse effect, the client should increase their intake of high-potassium foods. Choice A is incorrect because furosemide typically leads to decreased blood pressure, not increased. Choice C is incorrect because furosemide is used to reduce swelling, not increase it. Choice D is incorrect because the second dose of furosemide should be taken in the morning to prevent nocturia.
