Which nursing action is appropriate when pulling the plunger of the syringe back prior to administering medication and blood is aspirated in the syringe?

Choice A reason: Blood indicates vascular entry; discarding prevents unintended IV delivery of an IM drug, avoiding rapid absorption risks and ensuring proper route administration. Choice B reason: Giving with blood risks IV administration; IM drugs aren’t formulated for this, potentially causing embolism or toxicity, violating safety administration principles. Choice C reason: Changing the needle leaves contaminated medication; blood-mixed drugs are unsafe, and this fails to address the compromised dose integrity fully. Choice D reason: Omitting skips treatment needlessly; the issue is procedural, not the order, and restarting ensures the patient receives the intended therapy safely.
