Answer and Explanation

The Correct Answer is D

Rationale:

Ordered Dose:

The prescription is for 12 mg of Celestone Soluspan (betamethasone) IM every 24 hours for 2 doses.

Available Dose (from label): The vial contains 6 mg/mL.

Dosage Calculation: Using the formula:

Volume to administer (mL) =  Available concentration (mg/mL)  /  Ordered dose (mg)

Volume to administer = 12mg  / 6mg/mL = 2 mL

Administration Route:

The order specifies IM (intramuscular) administration, aligning with the label instructions.

Thus, 2 mL IM is the correct dosage to administer.

Correct Answer is A

Explanation

Given:

Ordered dose of Heparin: 15 units/kg/hr

Patient weight: 82 kg

Total Heparin in solution: 25,000 units

Volume of solution: 250 mL

Step 1: Calculate the total dose of Heparin in units/hr:

Total dose (units/hr) = Ordered dose (units/kg/hr) x Patient weight (kg)

Total dose (units/hr) = 15 units/kg/hr x 82 kg

Total dose (units/hr) = 1230 units/hr

Step 2: Calculate the concentration of Heparin in the solution:

Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL)

Concentration (units/mL) = 25,000 units / 250 mL

Concentration (units/mL) = 100 units/mL

Step 3: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total dose (units/hr) / Concentration (units/mL)

Infusion rate (mL/hr) = 1230 units/hr / 100 units/mL

Infusion rate (mL/hr) = 12.3 mL/hr

Correct Answer is A

Explanation

Given:

Value in grams: 5,524 g

To convert grams to kilograms, we need to divide the value by 1000.
