Your patient appears withdrawn and depressed. Which of the following would not be an effective intervention?

Choice A reason: The myocardium requires a constant supply of oxygen to function properly. Coronary artery disease (CAD) causes a reduction in blood flow due to narrowed or blocked coronary arteries, leading to a lack of oxygen in the heart muscle, which can result in angina or chest pain.

Choice B reason: While increased cardiac workload can exacerbate chest pain, it is not the primary cause of pain in CAD. The pain is primarily due to ischemia, which is the lack of oxygen and nutrients to the heart tissue due to reduced blood flow.

Choice C reason: Interrupted electrical activity can lead to arrhythmias or heart attack, but it is not the direct cause of pain in CAD. The pain is related to ischemia, not electrical disturbances.

Choice D reason: A lack of nutrients, including oxygen, to the heart does contribute to the pain experienced in CAD; however, the primary factor is the insufficient oxygen supply, which is explicitly stated in choice A.

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.
