Correct Answer: A

Rationale: In a child with nephrotic syndrome, the presence of edema is due to fluid retention caused by protein loss in the urine. Prednisone, a corticosteroid, helps reduce inflammation and decrease the loss of protein in the urine, leading to a decrease in edema. Therefore, decreased edema is an indication that the prednisone treatment is effective in managing the nephrotic syndrome.

Rationale: Morphine, as a strong opioid agonist, has the highest likelihood of causing serious respiratory depression due to its potent effects on the central nervous system. While Pentazocine and Hydrocodone can also cause respiratory depression, they are less likely to do so compared to morphine. Nalmefene, an opioid antagonist, is used to reverse respiratory depression caused by opioids rather than causing it.
