The nurse identifies that a client is having occasional premature ventricular contractions (PVCs) on the cardiac monitor.
 
  The nurse reviews the client's laboratory results and determines that which of the following results would be consistent with the observation? 1. Serum sodium level of 150 mEq/L
  2. Serum chloride level of 95 mEq/L
  3. Serum calcium level of 11.5 mg/dL
  4. Serum potassium level of 2.8 mEq/L

Rationale: The nurse assesses the client's serum laboratory study results for hypokalemia. The client may experience PVCs in the presence of hypokalemia, because this electrolyte imbalance increases the electrical instability of the heart. The electrolyte imbalances mentioned in the other options do not have this effect.
