NCLEX PN Exam Cram - Nurselytic

Correct Answer: A

Rationale: The correct answer is to tell the patient to remain with the leg straight for at least another hour after a heart catheterization before starting ambulation. This period allows for proper healing and reduces the risk of complications such as bleeding or hematoma formation at the catheter insertion site. Starting ambulation too soon can disrupt the healing process and lead to adverse events.
Choice B is incorrect because limited ambulation should not be initiated shortly after the procedure as it may increase the risk of complications.
Choice C is incorrect as physical therapy consultation is not typically necessary for initial ambulation post-heart catheterization; this can be managed by nursing staff.
Choice D is incorrect as keeping the leg straight for 6 hours is excessive and unnecessary, potentially leading to complications such as deep vein thrombosis due to prolonged immobility.
