Practice Question
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.)
Answer Choices:
Correct Answer:
1
Rationale:
🔷Step 1: Calculate the volume for hydromorphone:
4 mg ÷ 10 mg/mL = 0.4 mL
🔷 Step 2: Calculate the volume for hydroxyzine:
25 mg ÷ 50 mg/mL = 0.5 mL
🔷 Step 3: Add both volumes together:
0.4 mL + 0.5 mL = 0.9 mL,
rounded to 1.0 mL
