A client who weighs 154 pounds receives a prescription for levothyroxine 1.6 mcg/kg by mouth (PO) daily. The medication is available in 112 mcg scored tablets. How many tablets should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["1"]
To calculate the number of tablets, we need to use the formula:
Number of tablets = Dose (mcg) / Strength (mcg/tablet)
First, we need to calculate the dose by multiplying the prescribed rate by the weight in kilograms. To convert the weight from pounds to kilograms, we multiply by 0.454. In this case, 154 pounds is equivalent to 69.916 kg.
Plugging in the given values, we get:
Number of tablets = 1.6 mcg/kg x 69.916 kg / 112 mcg
Simplifying, we get:
Number of tablets = 1

Correct Answer is ["16"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 176 pounds is equivalent to 79.904 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 79.904 kg x 500 mL / 500000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 15.981 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 16 mL/h
Correct Answer is ["3.8"]
Explanation
To calculate the volume of oseltamivir suspension, we need to use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Since the client weighs 35 pounds, which is between 34 and 50.6 pounds, the recommended dose is 45 mg BID for 5 days. Plugging in this value and the concentration of oseltamivir suspension, we get:
Volume (mL) = 45 mg / 12 mg/mL
Simplifying, we get:
Volume (mL) = 3.75 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 3.8 mL
