A nurse is preparing to administer amantadine 150 mg PO every 12 hours. Available is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose?
(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 ["15"]
Step 1: The total amount of amantadine required per dose is 150 mg.
Step 2: Each 5 mL of syrup contains 50 mg of amantadine.
Step 3: To find out how many mL are needed, we divide the total amount required by the amount in each 5 mL of syrup. So, (150 mg ÷ 50 mg/5 mL).
Step 4: The result is 15 mL.
So, the nurse should administer 15 mL per dose. This is already a whole number, so no rounding is necessary.

Correct Answer is C
Explanation
Choice A reason: pH 7.30 with elevated HCO3- and PaCO2 suggests compensated respiratory acidosis, not typical for chronic kidney disease.
Choice B reason: pH 7.55 with elevated HCO3- and low PaCO2 suggests metabolic alkalosis, which is not typical for chronic kidney disease.
Choice C reason: pH 7.25 with decreased HCO3- and PaCO2 suggests metabolic acidosis, which is expected in chronic kidney disease due to the accumulation of acids.
Choice D reason: pH 7.50 with low HCO3- and PaCO2 suggests compensated metabolic alkalosis, which is not typical for chronic kidney disease.
Correct Answer is B
Explanation
Choice A reason: Hyperkalemia is not typically associated with corticosteroid therapy. Corticosteroids can lead to increased excretion of potassium, not retention.
Choice B reason: Hypokalemia is a common side effect of corticosteroid therapy due to increased excretion of potassium in the urine.
Choice C reason: Hypomagnesemia is not commonly associated with corticosteroid therapy.
Choice D reason: Hypermagnesemia is not typically induced by corticosteroid therapy.
