A nurse is caring for a client who has had a traumatic fall. Which of the following interventions should the nurse implement first?

A. "The heart and the coronary arteries weaken, leading to poor perfusion and resulting in angina": This statement is inaccurate. While angina can result from poor perfusion to the heart muscle, it is not typically due to weakening of the heart and coronary arteries. Angina often occurs due to coronary artery narrowing or blockage, leading to reduced blood flow and oxygen delivery to the myocardium.

B. "Coronary arteries become more elastic causing the arteries to stretch as individuals age causing the heart not to receive enough oxygen": This statement is incorrect. Coronary arteries do not become more elastic with age; in fact, they tend to become less elastic due to the development of atherosclerosis, which leads to arterial stiffening and decreased compliance. Atherosclerosis can cause narrowing or occlusion of the coronary arteries, resulting in reduced oxygen delivery to the heart muscle.

C. "Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle. Manifestations occur due to dilation of coronary arteries with increased blood flow causing increased pressure": This statement is partially incorrect. While it accurately describes the consequences of coronary artery narrowing (decrease in diameter) leading to insufficient blood, oxygen, and nutrient delivery to the heart muscle, the second part of the statement regarding dilation of coronary arteries with increased blood flow causing increased pressure is inaccurate. Coronary artery dilation is a compensatory response to increased demand for oxygen, aiming to improve blood flow to the myocardium. However, dilation alone does not increase pressure in the coronary arteries.

D. "Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle": This statement is accurate. Coronary artery disease (CAD) involves the progressive narrowing of the coronary arteries due to atherosclerosis, which reduces blood flow to the myocardium. As the arteries narrow, there is insufficient blood, oxygen, and nutrients reaching the heart muscle, leading to manifestations such as angina, myocardial ischemia, and potentially myocardial infarction.

A. Lie on your back when sleeping: Lying on the back when sleeping may be recommended initially after cochlear implant surgery to avoid putting pressure on the surgical site. However, this instruction should not be included in the plan of care indefinitely. Once the client is comfortable and the surgical site is healing well, they should be allowed to sleep in any position that is comfortable for them.

B. Lie on your front when sleeping: Lying on the front when sleeping is not typically recommended after cochlear implant surgery, as it may put pressure on the surgical site and disrupt healing. This position could potentially cause discomfort and increase the risk of complications. Therefore, this instruction should not be included in the plan of care.

C. Resume your exercise routine: Resuming the exercise routine immediately after cochlear implant surgery may not be advisable. The client should be instructed to avoid strenuous activities and heavy lifting for a certain period as advised by the healthcare provider. Engaging in vigorous exercise too soon after surgery could potentially disrupt the healing process and increase the risk of complications. Therefore, this instruction should not be included in the plan of care immediately after surgery.

D. Wash your hair 24 hr after surgery: After cochlear implant insertion, it is important to keep the surgical site clean to prevent infection. Washing the hair 24 hours after surgery helps to maintain cleanliness and hygiene without disrupting the surgical site. It is typically safe to wash the hair after this period as long as gentle care is taken to avoid excessive manipulation of the implant site.
