(Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["37.5"]

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

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

Plugging in the given values, we get:

Infusion rate (mL/h) = 15 mg/h x 250 mL / 50 mg

Simplifying, we get:

Infusion rate (mL/h) = 75 mL / 2 h

Dividing both sides by 2, we get:

Infusion rate (mL/h) = 37.5 mL/h

Correct Answer is ["1"]

Explanation

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 ["7672.32"]

Explanation

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

Amount (units) = Dose (units/kg) x Weight (kg)

First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 211.2 pounds is equivalent to 95.904 kg.

Plugging inthe given values, we get:

Amount (units) = 80 units/kg x 95.904 kg

Simplifying, we get:

Amount (units) = 7,672.32 units
