A nurse is caring for a client who reports chest pain. Which of the following laboratory findings indicates myocardial damage?

A. Encouraging the client to gain 2.3 kg (5 lb) per week may be excessive and unrealistic, potentially contributing to feelings of failure and exacerbating the client's condition.

B. Weighing the client once per week throughout hospitalization is important for monitoring weight changes, but it does not specifically address the immediate post-meal monitoring needed to prevent complications such as purging.

C. Monitoring the client for 1 hr after meals helps prevent behaviors such as purging or other forms of compensatory behaviors that may occur immediately after eating.

D. Allowing the client to choose meal times may not be appropriate as it can perpetuate disordered eating patterns. Establishing regular meal times is important for promoting consistent eating habits.

A. 3hr oral glucose tolerance test - This test is typically used for diagnosing gestational diabetes or impaired glucose tolerance, not for long-term management.

B. HbA1c - Hemoglobin A1c reflects the average blood glucose levels over the past 2-3 months and is a reliable indicator of long-term glycemic control.

C. Fasting blood glucose test - This provides a snapshot of blood glucose levels at a specific point in time and is not as reliable for assessing long-term glycemic control as HbA1c.

D. Urinalysis for ketones - Urinalysis for ketones is useful for detecting acute complications such as diabetic ketoacidosis but does not reflect long-term management of blood glucose levels.
