A nurse is preparing to administer morphine 4 mg IV bolus. Available is morphine injection 10 mg/ml. How many ml. should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.4"]

- 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.

Correct Answer is ["3.5"]

Explanation

To convert pounds to kilograms, divide by 2.2: 154 lb / 2.2 = 70 kg. Then multiply by the dosage per kilogram: 70 kg x 50 mcg/kg = 3500 mcg. Next, convert micrograms to milligrams by dividing by 1000: 3500 mcg / 1000 = 3.5 mg. Finally, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 3.5 mg / 1 mg/mL x 1mL = 3.5 mL. Round to the nearest tenth: 3.5 mL. Therefore, the nurse should administer 3.5 mL of milrinone.

Correct Answer is ["200"]

Explanation

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.
