Answer to Question 1

This drug dosage calculation combines the conversion of ordered units into available units and the computation of drug dosage into one step. (Desired) 10 gr x (60 mg/1 gr) x (Available) 1 tablet/300 mg = 2 tablets.

Answer to Question 2

The Mantoux test is designed to identify people with active tuberculosis, with exposure to tu-berculosis, or needing further testing. Positive reaction must have erythema and induration of 9 mm or more in size; 5 to 9 mm are questionable; areas under 5 mm are negative.
