A nurse is preparing to administer 0.9% sodium chloride 1,800 mL IV to infuse over 12 hr for a client who has postpartum hemorrhage. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["150"]
To calculate the infusion rate, you would divide the total volume of IV fluid (1,800 mL) by the number of hours over which it is to be infused (12 hr). This calculation gives you 150 mL/hr.

Correct Answer is ["0.5"]
Explanation
To calculate the correct dosage of heparin, the nurse needs to use the formula: (desired dose ÷ available concentration) = volume to administer. In this case, the desired dose is 5,000 units, and the available concentration is 10,000 units per mL. Therefore, the calculation would be: (5,000 units ÷ 10,000 units/mL) = 0.5 mL. So, the nurse should administer 0.5 mL of heparin to the client. This dosage should be validated with another nurse to ensure accuracy and safety for the client.
Correct Answer is ["25"]
Explanation
To calculate the volume of propranolol solution the client should self-administer per dose, you would divide the total daily dose by the concentration of the solution. The prescription is for 200 mg daily, to be taken in equal doses every 12 hours, which means each dose should be 100 mg. With the solution concentration at 4 mg/mL, you would divide 100 mg by 4 mg/mL to find the volume needed for one dose. This calculation results in 25 mL per dose.
