A. Dilute the medication with 10 mL of normal saline.
B. Verify medication compatibility with the IV fluid.
C. Administer the medication over 30 seconds.
D. Aspirate for blood return before administration.
Answer: B. Verify medication compatibility with the IV fluid.
Rationale: Incompatibility can cause precipitation, resulting in serious harm to the
