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 ["0.25"]
Explanation
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.
Correct Answer is ["1.5"]
Explanation
To calculate the amount of phenobarbital injection needed for each dose after the initial dose, we need to divide the prescribed dose (200 mg) by the concentration of the injection (130 mg/mL). This gives us:
200 mg / 130 mg/mL = 1.538 mL
To round this to the nearest tenth, we look at the hundredths place and see that it is 3, which is less than 5, so we round down and drop the rest of the digits. This gives us:
1.5 mL
Therefore, the nurse should administer 1.5 mL of phenobarbital injection per dose after the initial dose.
