HESI RN Dosage Calculation Proctored Exam
Calculation
The nurse is preparing a client's dose of an IM analgesic in a single syringe. The prescription is hydromorphone 4 mg and hydroxyzine 25 mg. The hydromorphone is available in a 10 mg/mL ampule, and the hydroxyzine is available in a 50 mg/mL vial. How many total mL should the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest tenth.)
mL
Explanation & Rationale
Step 1: Calculate the hydromorphone volume required. 4 mg ÷ 10 mg/mL = 0.4 mL Step 2: Calculate the hydroxyzine volume required. 25 mg ÷ 50 mg/mL = 0.5 mL Step 3: Sum the volumes. 0.4 mL + 0.5 mL = 0.9 mL
