The telemetry unit nurse is reviewing laboratory results for a client who is scheduled for an operative procedure later in the day. The nurse notes on the laboratory report that the client has a serum potassium level of 6.5 mEq/L (6.5 mmol/L), indicative of hyperkalemia. The nurse informs the health care provider of this laboratory result because the nurse recognizes hyperkalemia increases the client's operative risk for:
bleeding and anemia.
infection.
cardiac problems.
fluid imbalances.
The Correct Answer is C
A. Hyperkalemia does not directly cause bleeding or anemia.
B. Hyperkalemia is not associated with increased risk of infection.
C. Hyperkalemia increases the risk of cardiac problems, such as arrhythmias, which can be life-threatening, especially during surgery. Elevated potassium levels affect the electrical conduction system of the heart.
D. While potassium is involved in fluid and electrolyte balance, hyperkalemia itself is more critical for cardiac function than general fluid imbalances.
