- 10 mg / 10 to 14 days
- 15 mg / 10 to 14 days
- 20 mg / 10 to 14 days
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Zinc is given alongside ORS in every case of childhood diarrhoea because it speeds recovery and lowers recurrence over the next few months. The only decision needed is the dose by age.
Step 2: Use the WHO cut-off at 6 months. Below 6 months the daily dose is half a tablet, that is 10 mg. From 6 months upward the daily dose is a full 20 mg tablet. The course length is the same for both, namely 10 to 14 days.
Step 3: The child here is 12 months old, well past the 6 month line, so the full 20 mg per day for 10 to 14 days applies.
Step 4: Reject the alternatives: 10 mg is the infant dose, while 1 mg and 15 mg are not part of the standard schedule at all.
\[\boxed{\text{20 mg / 10 to 14 days}}\]
