Practice Question
A nurse is preparing to administer diphenhydramine 30 mg 1M stat to a client who is having an allergic reaction. Available is diphenhydramine 50 mg/l mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Answer Choices:
Correct Answer:
0.6
Rationale:
🔷 Use dose–volume formula: Volume = Ordered dose ÷ Stock concentration = 30 mg ÷ 50 mg/mL.
🔷 Calculation yields 0.6 mL, which matches IM dose accuracy to the nearest tenth.
🔷 No trailing zero and use a leading zero when needed are medication-safety standards.
🔷 Drawing 0.6 mL prevents underdose (e.g., 0.5 mL) or overdose (≥0.7 mL).
🔷 Verify drug, dose, route (IM), time (stat) against MAR before administration.
