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 ["83"]

Explanation

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

Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)

First, we need to convert the volume from liters to milliliters by multiplying by 1,000. In this case, 1 liter is equivalent to 1,000 mL.

To convert the time from hours to minutes, we need to multiply by 60. In this case, 12 hours is equivalent to 720 minutes.

Plugging in the given values, we get:

Infusion rate (gtt/min) = 1,000 mL x 60 gtt/mL / 720 min

Simplifying, we get:

Infusion rate (gtt/min) = 83.33 gtt/min

Rounding to the nearest whole number, we get:

Infusion rate (gtt/min) = 83 gtt/min

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
