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. Portable suction may be needed for some infants but is not specifically indicated for tetralogy of Fallot.

B. A cervical collar is used for neck support in patients with suspected cervical spine injuries and is not indicated for tetralogy of Fallot.

C. A hemodialyzer is used for renal replacement therapy and is not indicated for tetralogy of Fallot.

D. A pulse oximeter is essential for monitoring oxygen saturation levels in infants with tetralogy of Fallot, as they may experience cyanosis and hypoxemia. Monitoring oxygen saturation helps guide interventions and management.
