A nurse is preparing to administer hydromorphone 2.5 mg PO every 6 hours for a client with severe pain. The amount available comes in a liquid form (5 mg/5 mL). How many mL should the nurse administer per day (24 hours)? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
B
Rationale
To calculate the amount of hydromorphone to be administered per day, we first determine the total daily dosage (2.5 mg every 6 hours = 10 mg/day). Since the liquid form is 5 mg/5 mL, we need to administer 10 mg/day. This means we need to administer 10 mL/day (10 mg ├À 5 mg/mL = 2 mL; 2 mL x 5 mL = 10 mL). Therefore, the correct answer is B (10 mL). Other choices are incorrect because they do not accurately reflect the calculated dosage based on the given information.
