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 ["1.5"]
Explanation
To calculate the number of tablets, we need to use the formula:
Number of tablets = Dose (mg) / Strength (mg/tablet)
First, we need to convert the dose and the strength from micrograms (mcg) to milligrams (mg) by dividing by 1,000. In this case, 0.075 mg is equivalent to 75 mcg and 50 mcg is equivalent to 0.05 mg.
Plugging in the given values, we get:
Number of tablets = 75 mcg / 50 mcg
Simplifying, we get:
Number of tablets = 1.5
Rounding to the nearest tenth, we get:
Number of tablets = 1.5
Correct Answer is ["602"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 10 mg/min x 250 mL / 50 mg
Simplifying, we get:
Infusion rate (mL/h) = 500 mL / 50 min
Converting minutes to hours, we get:
Infusion rate (mL/h) = 500 mL / 0.83 h
Dividing both sides by 0.83, we get:
Infusion rate (mL/h) = 602.41 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 602 mL/h
