Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Use the national age-based chloroquine chart that counts 150 mg base tablets. The 5 to 8 year row is allotted two tablets per dosing day at the start of treatment.
Step 2: Convert tablets to milligrams: 2 multiplied by 150 mg gives 300 mg of base for this child.
Step 3: The 1 tablet (150 mg) figure belongs to 1 to 4 years, while 3 or 4 tablets (450 to 600 mg) apply to 9 to 14 years and to adults, so they do not fit a 4 to 8 year old.
\[\boxed{300\ \text{mg}}\]
Step 2: Convert tablets to milligrams: 2 multiplied by 150 mg gives 300 mg of base for this child.
Step 3: The 1 tablet (150 mg) figure belongs to 1 to 4 years, while 3 or 4 tablets (450 to 600 mg) apply to 9 to 14 years and to adults, so they do not fit a 4 to 8 year old.
\[\boxed{300\ \text{mg}}\]
