A nurse is preparing to administer potassium gluconate 40 mEq PO. Available is potassium gluconate liquid 20 mEq/15 mL. How many mL should the nurse administer?
(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 ["30"]
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 ["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 ["1"]
Explanation
To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (50 mcg / 0.05 mg) x 1 mL = 1 mL. Round to the nearest whole number: 1 mL.
