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 ["4"]
Explanation
To administer verapamil 10 mg IV bolus, the nurse should use the following formula: mL = (mg / mg/mL) x mL. Plugging in the values from the question, we get: mL = (10 / 5) x 2. Simplifying, we get: mL = 4. Therefore, the nurse should administer 4 mL of verapamil injection.
Correct Answer is ["1.5"]
Explanation
To calculate the amount of phenobarbital to administer per dose after the initial dose, the nurse should use the following formula:
mL = (dose in mg) / (concentration in mg/mL)
The dose in mg is 200 mg, and the concentration in mg/mL is 130 mg/mL. Plugging these values into the formula, we get:
mL = (200 mg) / (130 mg/mL)
mL = 1.5385
Rounding to the nearest tenth, the nurse should administer 1.5 mL per dose after the initial dose.
