A nurse is preparing to administer propranolol 2 mg by intermittent IV bolus over 15 min. Available is propranolol 2 mg in 50 ml. dextrose 5% in water. 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.)

Answer and Explanation

The Correct Answer is ["200"]

To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:

Infusion rate (mL/hr) = Volume (mL) / Time (hr)

We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:

Infusion rate (mL/hr) = 50 mL / 0.25 hr

Infusion rate (mL/hr) = 200 mL/hr

Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.

Correct Answer is ["14"]

Explanation

To answer this question, the nurse needs to perform the following steps:

Convert the client's weight from pounds to kilograms by dividing it by 2.2. 154 lb / 2.2 = 70 kg.

Multiply the client's weight by the loading dose of phenytoin to get the total dose in milligrams. 70 kg x 10 mg/kg = 700 mg.

Divide the total dose by the concentration of phenytoin to get the volume in milliliters. 700 mg / 50 mg/mL = 14 mL.

Round the volume to the nearest whole number. The nurse should administer 14 mL of phenytoin by IV bolus.

Correct Answer is ["0.4"]

Explanation

- To calculate the amount of morphine injection needed, use the formula: D/H x V = A, where D is the desired dose, H is the dose on hand, V is the volume on hand, and A is the amount to administer.
- Plug in the values from the question: 4 mg / 10 mg x 1 ml = 0.4 ml
- Round the answer to the nearest tenth: 0.4 ml
- The nurse should administer 0.4 ml of morphine injection.
