A nurse is preparing to administer milrinone 50 mcg/kg IV loading dose to a client who weighs 154 lb. Available is milrinone 1 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 ["3.5"]

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 1 mL = 3.5 mL. Round to the nearest tenth: 3.5 mL. Therefore, the nurse should administer 3.5 mL of milrinone.

Correct Answer is ["30"]

Explanation

To administer potassium gluconate 40 mEq PO, the nurse should use the following formula: mL = (mEq / mEq/mL) x mL. Plugging in the values from the question, we get: mL = (40 / 20) x 15. Simplifying, we get: mL = 30.

Therefore, the nurse should administer 30 mL of potassium gluconate liquid.

Correct Answer is ["375"]

Explanation

To answer this question, you need to use the formula: rate (mL/hr) = volume (mL) / time (hr). Plug in the given values and you get: rate = 750 / 2.

Simplify and you get: rate = 375.

Therefore, the nurse should set the IV pump to deliver 375 mL/hr.
