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

Amount (units) = 7,672.32 units
Correct Answer is ["24"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (units/h) x Volume (mL) / Concentration (units)
First, we need to adjust the dose according to the sliding scale prescription based on the PTT result. In this case, since the PTT is less than 65 seconds, we need to increase the dose by 200 units/hour. Therefore, the new dose is 1,000 units/hour + 200 units/hour = 1,200 units/hour.
Plugging in the given values, we get:
Infusion rate (mL/h) = 1,200 units/h x 500 mL / 25,000 units
Simplifying, we get:
Infusion rate (mL/h) = 24 mL/h
