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.)
Answer and Explanation

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 ["133"]

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, 132 pounds is equivalent to 59.928 kg.

Plugging in the given values, we get:

Infusion rate (mL/h) = 2 mcg/min x 59.928 kg x 500 mL / 45000 mcg

Simplifying, we get:

Infusion rate (mL/h) = 132.84 mL/h

Rounding to the nearest whole number, we get:

Infusion rate (mL/h) = 133 mL/h

Correct Answer is ["7200"]

Explanation

To calculate the amount of heparin received, we need to use the formula:

Amount (units) = Infusion rate (mL/h) x Time (h) x Concentration (units/mL)

First, we need to calculate the concentration of heparin in the solution by dividing the total units by the total volume. In this case, it is 20,000 units / 500 mL.

Plugging in the given values, we get:

Amount (units) = 15 mL/h x 12 h x 20,000 units / 500 mL

Simplifying, we get:

Amount (units) = 7,200 units
