Feedback:
The nurse should administer 4½ tablets to give 1½ mg of the medication. The nurse should use the formula method, following the rules for dividing fractions. The nurse should invert the divisor, multiply it by the dividend, and reduce the fraction to its lowest terms. Therefore, 3/2 × 3/1 is equal to 9/2 or 4½ and not 4, 5, or 5½ tablets.
