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 aspiration indicates vascular entry; discarding prevents IV administration of a drug meant for another route, avoiding rapid absorption risks or contamination. Choice B reason: Giving despite blood risks unintended IV delivery; drugs like IM injections aren’t formulated for this, potentially causing toxicity or embolism. Choice C reason: Changing the needle doesn’t address blood-mixed medication; it remains unsafe for injection, as the dose is compromised and potentially contaminated. Choice D reason: Omitting skips treatment unnecessarily; the issue is procedural, not the order, and restarting ensures the patient receives the intended therapy safely.
