The nursing interventions for a patient with major depression would include all the following except:

Choice A reason: Having the patient sit alone while reviewing rules does not address the immediate risk of injury due to hyperactivity.

Choice B reason: Reinforcing coping mechanisms can help the patient manage hyperactivity and reduce the risk of injury.

Choice C reason: Placing the patient with another hyperactive patient could potentially exacerbate the situation and increase the risk of injury.

Choice D reason: While administering medication may be necessary, it should be done in conjunction with other interventions that address behavior management.

Choice A reason: Interrupted electrical activity to areas of the heartWhen it comes to the pain associated with coronary artery disease (CAD), interrupted electrical activity is not the primary cause. While abnormal electrical activity can lead to arrhythmias, it is not the primary source of pain in CAD. The pain in CAD is primarily related to inadequate blood flow and oxygen supply to the heart muscle.

Choice B reason: Lack of sufficient oxygen to the myocardiumThis is the correct answer. Coronary artery disease results in the narrowing or blockage of coronary arteries, which supply oxygen-rich blood to the heart muscle. When these arteries become narrowed due to plaque buildup (atherosclerosis), the heart muscle does not receive enough oxygen. This insufficient oxygen supply leads to chest pain (angina) and discomfort.

Choice C reason: Increased cardiac workloadWhile increased cardiac workload can contribute to heart-related symptoms, it is not the primary cause of pain in coronary artery disease. Increased workload may occur during physical exertion or stress, but the underlying issue in CAD is the reduced blood flow due to narrowed or blocked arteries.

Choice D reason: Lack of nutrients into the heartWhile nutrients are essential for overall heart health, the primary concern in coronary artery disease is the lack of oxygen supply. The pain associated with CAD is primarily related to inadequate oxygen delivery to the heart muscle, not specifically a lack of nutrients.
