What is the primary pathophysiological reason for performing Coronary Artery Bypass Surgery?
To reduce overall contractility of the heart muscle.
To reduce plaque buildup in the carotid artery.
To increase oxygen supply to the heart muscle.
To increase the myocardial workload.
The Correct Answer is C
Choice A rationale
Reducing the overall contractility of the heart muscle is not the primary reason for performing Coronary Artery Bypass Surgery (CABG)4. In fact, reducing the contractility of the heart muscle could potentially decrease the heart’s ability to pump blood effectively.
Choice B rationale
Reducing plaque buildup in the carotid artery is not the primary reason for performing CABG4. While plaque buildup in the carotid artery can lead to serious conditions such as stroke, CABG is specifically performed to bypass blocked coronary arteries, not carotid arteries.
Choice C rationale
Increasing the oxygen supply to the heart muscle is the primary reason for performing CABG4. When coronary arteries become blocked or narrowed due to plaque buildup, the heart muscle may not receive enough oxygen-rich blood. CABG is performed to create a new route, or bypass, around the blocked artery, which improves blood flow and oxygen supply to the heart muscle.
Choice D rationale
Increasing the myocardial workload is not the primary reason for performing CABG4. In fact, increasing the workload of the heart could potentially exacerbate heart disease and lead to complications such as heart failure.

Correct Answer is C
Explanation
Choice A rationale
Beginning cardiopulmonary resuscitation (CPR) is not the first action a nurse should take when a patient’s heart monitor shows a pattern of undulations of varying contours and amplitude with no measurable ECG pattern.
Choice B rationale
Cardioverting the client with a biphasic defibrillator is not the first action a nurse should take when a patient’s heart monitor shows a pattern of undulations of varying contours and amplitude with no measurable ECG pattern.
Choice C rationale
The first action a nurse should take when a patient’s heart monitor shows a pattern of undulations of varying contours and amplitude with no measurable ECG pattern is to assess the patient’s airway, breathing, and circulation.
Choice D rationale
Administering an amiodarone bolus followed by a drip is not the first action a nurse should take when a patient’s heart monitor shows a pattern of undulations of varying contours and amplitude with no measurable ECG pattern.
Correct Answer is A
Explanation
Choice A rationale
Vasotec, an Angiotensin-Converting Enzyme (ACE) inhibitor, is commonly used to treat conditions like high blood pressure and heart failure. It works by relaxing blood vessels, which allows blood to flow more easily and reduces blood pressure.
Choice B rationale
Decreased urine output is not a typical outcome of taking Vasotec. In fact, ACE inhibitors like Vasotec can sometimes increase urine output by improving kidney function.
Choice C rationale
Increased appetite is not a known effect of Vasotec. If a patient experiences a significant change in appetite while taking this medication, they should consult their healthcare provider.
Choice D rationale
Increased fluid retention is not a typical outcome of taking Vasotec. ACE inhibitors like Vasotec are often used to help reduce fluid retention in patients with conditions like heart failure.
