Question

The nurse observes a prominent U wave on the client's electrocardiograph (ECG) tracing. What is the most appropriate action for the nurse to take?

a. Document the finding as a normal variant.
b. Review the client's daily electrolyte results.
c. Move the crash cart closer to the client's room.
d. Call for an immediate electrocardiogram.

Answer 1

The nurse should review the client's daily electrolyte results when a prominent U wave is observed on an ECG tracing, as this could indicate electrolyte imbalances such as hypokalemia or hypercalcemia that require attention.

Step-by-step explanation:

When a nurse observes a prominent U wave on a client's ECG tracing, the most appropriate action to take is to review the client's daily electrolyte results. Prominent U waves can be associated with conditions such as hypokalemia, hypercalcemia, or can be due to medications. Thus, checking electrolyte levels will help identify if there is an imbalance that requires correction. It is also important to consider other factors and rule out any life-threatening causes, but the immediate action would be to look at electrolytes before determining if further emergency action or additional testing is needed. Documenting the finding or moving the crash cart closer could be subsequent actions depending on the patient's condition and the nurse's assessment; calling for an immediate electrocardiogram depends on whether there has been a significant change in the patient's condition.
