B. A client who has a serum potassium level of 4.3 mEq/L
C. A client who has an SaO2 of 96%
D. A client who has COPD
E. A client who underwent stent placement in a coronary artery - answerA. CORRECT:
A client who has an acid‐base imbalance such as metabolic alkalosis is at risk for a
dysrhythmia.
B. A serum potassium of 4.3 mEq/L is within the expected reference range and does not
increase the risk of a dysrhythmia.
C. SaO2 of 96% is within the expected reference range and does not increase the risk
of a dysrhythmia.
D. CORRECT: A client who has lung disease, such as COPD, is at risk for a
dysrhythmia.
E. CORRECT: A client who has cardiac disease and underwent a stent placement is at
risk for a dysrhythmia.

therapy for 4 to 6 weeks prior to the procedure.
