Correct Answer: B

Rationale: The client should contact their provider if their heart rate drops below 60 beats per minute, as this could indicate digoxin toxicity.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid crowded places. Immunocompromised clients undergoing chemotherapy are at a higher risk of infections, so avoiding crowded places can help reduce exposure to pathogens. Wearing a mask at home is not necessary unless someone in the household is sick. Drinking unfiltered water can introduce harmful bacteria, increasing the risk of infection. Avoiding washing hands frequently is incorrect as hand hygiene is crucial in preventing the spread of infections.

Correct Answer: B

Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion through increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. Monitoring sodium, calcium, and magnesium levels is not typically associated with furosemide therapy, making choices A, C, and D incorrect.

Correct Answer: A

Rationale: The correct answer is A: Perform Kegel exercises daily. After a radical prostatectomy, Kegel exercises are beneficial as they help strengthen the pelvic floor muscles, aiding in urinary control and recovery. Choice B is incorrect because recommending 3 hours of light exercise daily may not be suitable immediately postoperatively. Choice C is incorrect as personal hygiene, including bathing, is important for postoperative care. Choice D is incorrect because sitting for more than 2 hours does not specifically relate to the client's postoperative care needs.

Correct Answer: A

Rationale: The Z-track method should be used to administer IM injections in obese clients to prevent medication from leaking into subcutaneous tissue. Using a longer needle (1.5 inches) ensures that the medication reaches the muscle mass adequately. Choice C is incorrect because the deltoid muscle is not ideal for IM injections in obese clients due to inadequate muscle mass. Administering the injection at a 90° angle (perpendicular to the skin) is recommended for IM injections to ensure proper delivery into the muscle.
