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 ["17"]

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) = 0.5 mg/min x 200 mL / 360 mg

Simplifying, we get:

Infusion rate (mL/h) = 100 mL / 360 min

Converting minutes to hours, we get:

Infusion rate (mL/h) = 100 mL / 6 h

Dividing both sides by 6, we get:

Infusion rate (mL/h) = 16.67 mL/h

Rounding to the nearest whole number, we get:

Infusion rate (mL/h) = 17 mL/h

Correct Answer is ["4.5"]

Explanation

To calculate the infusion rate, we need to use the formula:

Infusion rate (mL/h) = Dose (mcg/min) x Volume (mL) / Concentration (mcg)

First, we need to calculate the concentration of nitroglycerin in the solution by dividing the total amount by the total volume. In this case, it is 100 mg / 250 mL.

Since 1 mg is equal to 1,000 mcg, we need to multiply the concentration by 1,000 to get the same units as the dose. In this case, it is 100,000 mcg / 250 mL.

Plugging in the given values, we get:

Infusion rate (mL/h) = 30 mcg/min x 250 mL / 100,000 mcg

Simplifying, we get:

Infusion rate (mL/h) = 0.075 mL/min

To convert minutes to hours, we need to multiply by 60. In this case, it is 0.075 mL/min x 60 min.

Simplifying, we get:

Infusion rate (mL/h) = 4.5 mL/h

Rounding to the nearest tenth, we get:

Infusion rate (mL/h) = 4.5 mL/h
