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

A. A blood pressure of 94/68 mm Hg is within the normal range for a 7-year-old child and may indicate compensated dehydration rather than severe dehydration.

B. A urinary output of 30 mL/hr is insufficient and may indicate dehydration, but it does not specifically indicate severe dehydration.

C. A respiratory rate of 24/min is within the normal range for a 7-year-old child and is not specifically indicative of severe dehydration.

D. Tachycardia (heart rate >100 beats per minute) is a common finding in severe dehydration as the body attempts to compensate for decreased blood volume by increasing heart rate.

A. Wearing an N95 respirator is not necessary when caring for a client with neutropenia due to HIV unless the client has respiratory symptoms or is undergoing procedures that generate aerosols.

B. Inserting an indwelling urinary catheter should be avoided unless necessary, as it can

introduce the risk of infection, which is particularly concerning in clients with neutropenia.

C. Monitoring vital signs every 8 hours may not provide sufficient frequency for detecting changes in a client with neutropenia who may be at risk for rapid deterioration.

D. Using a dedicated stethoscope helps prevent the spread of infection to other clients by avoiding cross-contamination, which is especially important when caring for a client with neutropenia who is at increased risk of infection.
