Correct Answer is A

Explanation

A. Coronary artery bypass graft (CABG) surgery is typically recommended for patients with significant occlusion of the left main coronary artery, as it effectively restores blood flow to the heart muscle by bypassing the blocked artery.

B. Radiofrequency catheter ablation is used to treat arrhythmias, not coronary artery occlusions.

C. Implantable cardioverter-defibrillator (ICD) placement is for managing life-threatening arrhythmias, not directly for treating coronary artery blockages.

D. A circulatory assist device is used in severe cases of heart failure, but it does not address the underlying issue of coronary artery occlusion.

A. Provide passive range of motion for all extremities. B. Position the patient supine with head flat at all times. C. Measure the patient's urinary output every hour. D. Avoid the use of anticoagulant medications.

Correct Answer is C

Explanation

A. Passive range of motion may be performed, but it is not the priority in this situation.

B. The head of the bed should be elevated 30 degrees or less, not necessarily flat, to prevent complications.

C. Hourly urinary output measurement is essential because the intra-aortic balloon pump (IABP) can impair renal perfusion, and monitoring urine output helps assess renal function.

D. Anticoagulants are often necessary to prevent clot formation associated with the IABP, so avoiding them is not advised unless contraindicated.
