A nurse is providing teaching to a client who has coronary artery disease. Which of the following statements should the nurse include in the teaching to explain the correlation between changes in the coronary arteries and manifestations that occur?

Answer: C. "I am not worried. This sort of thing happens all the time to us 'old people.'"

A. "I brought an updated list of all the medications he takes at home to help you and the doctors determine what the cause of this could be."
This response indicates understanding and proactive involvement in the client’s care. An updated medication list is crucial in evaluating potential causes of delirium, as certain medications or interactions can contribute to changes in mental status.

B. "I notified our family members that they should not come visit for a while, until they are better."
This statement reflects an understanding of the need for a calm environment for the client experiencing delirium. Reducing stimuli and visitors can help the client focus on recovery. It indicates the spouse is aware of the potential impact of social interactions on the client’s condition.

C. "I am not worried. This sort of thing happens all the time to us 'old people.'"
This response indicates a need for further teaching. It reflects a possible misunderstanding of delirium as a normal part of aging, which can be dismissive of the seriousness of the condition. Delirium is often a sign of underlying medical issues and should be treated with concern and urgency. Clients and their families need to understand that delirium is not a typical or benign occurrence and requires appropriate evaluation and intervention.

D. "I am trying to stay positive. I know that most people return to normal, but it is hard to see them like this."
This statement indicates a hopeful attitude while acknowledging the difficulty of the situation. It shows understanding that recovery is possible and reflects the spouse's emotional processing of the situation. Maintaining a positive outlook can be beneficial for both the client and the family during recovery.

A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.

C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.

D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.
