tablets
Explanation & Rationale
Calculation: Convert the client's weight from pounds to kilograms: Weight (kg) = Weight (pounds) / 2.2 pounds/kg = 242 pounds / 2.2 pounds/kg = 110 kg Calculate the prescribed daily dose in micrograms: Daily dose (mcg) = Prescribed dose (mcg/kg/day) x Client's weight (kg) = 1.6 mcg/kg/day x 110 kg = 176 mcg/day Calculate the number of tablets to administer: Number of tablets = Daily dose (mcg) / Tablet strength (mcg/tablet) = 176 mcg / 88 mcg/tablet = 2 tablets
