Correct Answer: D

Rationale: The nurse should prioritize the client's privacy when addressing issues related to voiding discomfort in public places. Closing the curtain in the current room would offer immediate privacy and support the client's needs. Turning on the faucet is not an evidence-based intervention for voiding difficulties. Prescribing a diuretic is not appropriate without further assessment. While moving to a room with a private bathroom might be ideal, it may not be immediately feasible, making ensuring privacy in the current setting the most appropriate action.

Correct Answer: A

Rationale: The correct answer is A: hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in heart failure management. One of the major side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the blood. Monitoring for hyperkalemia is crucial as it can lead to serious cardiac arrhythmias. Choices B, C, and D are incorrect. Hypermagnesemia (choice B) is not typically associated with spironolactone use. Hypocalcemia (choice C) and hypoglycemia (choice D) are also not directly linked to the use of spironolactone in heart failure treatment.

Correct Answer: D

Rationale: The correct interventions to promote kidney health in an older adult client include ensuring adequate fluid intake to maintain hydration and leaving the bathroom light on at night to promote safe ambulation. Adequate hydration supports kidney function and helps prevent urinary tract infections. Encouraging the use of the toilet every 6 hours is not specific to kidney health and may not be individualized to the client's needs. Providing thorough perineal care after each voiding is important for hygiene but not directly related to promoting kidney health. Assessing for urinary retention and urinary tract infections is crucial but falls under assessment rather than interventions for promoting kidney health specifically.

Correct Answer: B

Rationale: The correct answer is 'B: Overflow incontinence.' The most common manifestation of urethral stricture after a urologic procedure is obstruction of urine flow. This obstruction can lead to overflow incontinence, which is the involuntary loss of urine when the bladder is distended. Severe pain is not typically associated with an obstruction of urine flow. Hypotension is unrelated to this issue. Blood-tinged urine is not a direct indication of an obstruction of urine flow but may indicate other conditions like trauma or infection.

Correct Answer: D

Rationale: During hemodialysis, a drop in blood pressure can occur due to fluid removal. To maintain blood pressure, the nurse should consider adjusting the rate of extracorporeal blood flow to optimize fluid removal without causing hypotension. Placing the client in the Trendelenburg position can help improve venous return and cardiac output. Administering a bolus of normal saline can help increase intravascular volume and support blood pressure. Therefore, all the actions listed in choices A, B, and C are appropriate measures to maintain blood pressure during hemodialysis. Choice D, 'All of the above,' is the correct answer as it encompasses all the relevant actions to address the dropping blood pressure effectively. Choices A, B, and C, when implemented together, can help manage hypotension during hemodialysis.
