While admitting a patient with pericarditis, what manifestations of this disorder should the nurse assess for?
Prolonged PR intervals.
Clubbing of the fingers.
Widened pulse pressure.
Pulsus paradoxus.
The Correct Answer is D
Choice A rationale
Prolonged PR intervals occur with first-degree AV block, not typically with pericarditis.
Choice B rationale
Clubbing of the fingers is a loss of the normal angle between the base of the nail and the skin. This finding can be found in endocarditis, congenital defects, and/or prolonged oxygen deficiency. It is not a typical manifestation of pericarditis.
Choice C rationale
Widened pulse pressure occurs with valvular heart disease, not typically with pericarditis.
Choice D rationale
Pulsus paradoxus is a sign of cardiac tamponade, a serious complication of pericarditis. As the compression of the heart increases, decreased left atrial filling decreases cardiac output.

Correct Answer is C
Explanation
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 A
Explanation
Choice A rationale
Standing frequently can help promote blood flow in the legs, which can be beneficial for a patient with arterial insufficiency. This is because standing engages the muscles in the legs, which helps push blood back up towards the heart.
Choice B rationale
Walking without shoes is not typically recommended for patients with arterial insufficiency. This is because these patients often have reduced sensation in their feet and may not notice if they step on something sharp or if a wound develops.
Choice C rationale
Vigorous massage of the legs is not usually recommended for patients with arterial insufficiency. While gentle massage can help promote blood flow, vigorous massage could potentially damage the arteries further.
Choice D rationale
Allowing the legs to dangle dependently often is not typically recommended for patients with arterial insufficiency. This position can actually increase swelling and discomfort in the legs.
