A patient with substance use disorder is in withdrawal. The nurse prioritizes which intervention?

Correct Answer: A

Rationale: Managing withdrawal symptoms is critical to ensure safety during detoxification.

Correct Answer: A

Rationale: Glomerulonephritis is often linked to streptococcal infections.

Correct Answer: D

Rationale: The renal cortex, the outer kidney layer, contains glomeruli and tubules, not pyramids (A), papillae (B), or calyces (C), which are in the medulla or pelvis. ‘None of the preceding' (D) fits, as these structures are absent from the cortex, making D correct.

Correct Answer: B

Rationale: Atrial natriuretic peptide (ANP), a natriuretic hormone, is produced by the heart's atria, not kidneys (B), to reduce sodium and volume. Kidneys produce renin and erythropoietin, making False the correct answer over True (A).

Correct Answer: D

Rationale: The loop of Henle (D), not vasa recta, creates the medullary osmotic gradient via countercurrent multiplication. Vasa recta maintains it, making D the correct clarification.
