Correct Answer is A

Explanation

A. Reye syndrome is correct because administering aspirin to children, especially during viral illnesses like the flu, can lead to this serious and potentially fatal condition characterized by acute encephalopathy and liver failure.

B. Excess antiplatelet action is incorrect; while aspirin does have antiplatelet effects, this is not the primary concern in a child with a viral illness.

C. Asthma is incorrect; while some individuals with asthma may have sensitivity to aspirin, it is not specifically related to the child's flulike illness.

D. Salicylate poisoning is incorrect; while high doses of aspirin can lead to toxicity, the immediate risk in the context of flu-like illness is Reye syndrome, which is a more specific concern.

A. 7 doses B. 5 doses C. 20 doses D. 12 doses

Correct Answer is C

Explanation

Total volume (mL) / Dose volume (mL) = Number of doses

First, we need to find the dose volume. Since the strength is 350 mg/5 mL, a single dose of 350 mg would require 5 mL.

Now, we can plug in the values into the formula:

100 mL / 5 mL/dose = 20 doses
