Question 1 of 5
A nurse is preparing to administer liquid famotidine 20 mg PO every 6 hr for GERD. Available is famotidine 40 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Volume = Desired dose / Available concentration per ml. Available concentration = 40 mg / 5 ml = 8 mg/ml. Desired dose = 20 mg. Volume = 20 mg / 8 mg/ml = 2.5 ml.
