The nurse is caring for a client admitted with unstable angina. The laboratory result for the initial troponin I is elevated in this client. The nurse should recognize what implication of this assessment finding?

This result indicates muscle injury but does not specify the source.

Because the client has a history of unstable angina, this is a poor indicator of myocardial injury.

This is only an accurate indicator of myocardial damage when it reaches its peak in 24 hours.

This is an accurate indicator of myocardial injury.

Answer and Explanation

The Correct Answer is D

A. This result indicates muscle injury but does not specify the source.

This statement is partly correct. An elevated troponin I level does indicate muscle injury, specifically damage to the heart muscle. However, troponin I is highly specific to cardiac muscle, so an elevated level would indeed specify the source as cardiac or myocardial injury.

B. Because the client has a history of unstable angina, this is a poor indicator of myocardial injury.

This statement is incorrect. A history of unstable angina does not diminish the significance of an elevated troponin I level. In fact, unstable angina is itself a serious condition that can lead to myocardial injury or heart attack, and an elevated troponin I level in this context indicates ongoing or recent myocardial damage.

C. This is only an accurate indicator of myocardial damage when it reaches its peak in 24 hours.

This statement is not entirely accurate. While it is true that troponin I levels may continue to rise and peak within 12-24 hours after the onset of myocardial injury, an elevated troponin I level at any point is still a significant indicator of myocardial damage. It's essential to recognize elevated troponin I levels promptly to initiate appropriate interventions and monitor the client's cardiac status closely.

D. This is an accurate indicator of myocardial injury.

This statement is correct. An elevated troponin I level is a highly sensitive and specific marker of myocardial injury. It indicates damage to the heart muscle, which can occur due to conditions like unstable angina, heart attack (myocardial infarction), myocarditis, or other cardiac issues. Therefore, recognizing an elevated troponin I level in a client with unstable angina is crucial for proper management and further evaluation.

Correct Answer is D

Explanation

A. "I will have canned chicken noodle soup with crackers and an apple for lunch": Canned soups are often high in sodium, and crackers can also contribute to sodium intake. This meal choice would not align with a low-sodium diet.

B. "I will have a ham and cheese sandwich for lunch": Processed meats like ham and cheese can be high in sodium, especially if they are not low-sodium options. This choice may not be suitable for a low-sodium diet unless specific low-sodium products are used.

C. "I will have a BLT and a side salad with cheese and croutons for lunch": Bacon, cheese, and croutons are all sources of sodium, so this meal would likely not be appropriate for a low-sodium diet unless modifications are made, such as using low-sodium bacon and limiting cheese and crouton amounts.

D. "I will have a baked potato with broiled chicken for dinner": This statement indicates an understanding of choosing low-sodium options. Baked potatoes and broiled chicken are generally low in sodium, especially if prepared without added salt or high-sodium seasonings. This choice aligns well with a low-sodium diet for someone with heart failure.

A. "If I take my blood pressure and it is normal, I don't have to take my blood pressure pills." B. "When getting up from bed, I will sit for a short period before standing up." C. "I will consult a dietician to help get my weight under control." D. "I think I'm going to sign up for a yoga class twice a week to help reduce my stress."

Correct Answer is A

Explanation

A. "If I take my blood pressure and it is normal, I don't have to take my blood pressure pills": This statement reflects a misunderstanding of hypertension management. Blood pressure medications are typically prescribed to help control blood pressure over the long term, regardless of individual blood pressure readings. Stopping medication without consulting a healthcare provider can be dangerous and is not recommended.

B. "When getting up from bed, I will sit for a short period before standing up": This statement demonstrates an understanding of orthostatic hypotension prevention, which is important for clients with hypertension and can be a side effect of certain medications.

C. "I will consult a dietician to help get my weight under control": This statement indicates the client's awareness of the importance of weight management in hypertension control and is a positive step toward healthy lifestyle changes.

D. "I think I'm going to sign up for a yoga class twice a week to help reduce my stress": This statement shows the client's proactive approach to stress reduction, which is beneficial for hypertension management as stress can contribute to elevated blood pressure.
