Explanation

A. Within 12 hours after burn trauma: Fluid loss is significant initially but peaks later.

B. 48 to 72 hours after burn trauma: The greatest fluid loss typically occurs within the first 48 to 72 hours as capillary permeability is at its highest and fluid resuscitation needs are greatest.

C. 24 to 36 hours after burn trauma: Fluid loss is still considerable but not at its peak; the peak is generally observed a bit later.

D. 36 to 48 hours after burn trauma: Fluid loss continues to be high, but the peak is generally reached a little later than this timeframe.

Correct Answer is A

Explanation

A. Nausea. Disulfiram causes an acute sensitivity to alcohol. When alcohol is consumed, it leads to an accumulation of acetaldehyde, causing unpleasant effects like severe nausea, vomiting, and headache, deterring the individual from drinking.
B. Blackouts. Blackouts are periods of memory loss due to heavy drinking but are not specifically induced by the combination of disulfiram and alcohol.
C. Hypertension. While disulfiram can cause cardiovascular effects, hypertension is not the primary or most severe side effect of consuming alcohol while on disulfiram.
D. Headaches. Headaches are indeed a part of the disulfiram-alcohol reaction, but the primary severe side effect leading to the aversion is nausea.
