A patient is admitted to the emergency department with severe fatigue and confusion. Laboratory studies are done. Which laboratory value will require the most immediate action by the nurse?

  • A. Arterial blood pH is 7.32.
  • B. Serum calcium is 18 mg/dL.
  • C. Serum potassium is 5.1 mEq/L
  • D. Arterial oxygen saturation is 91%.
Correct Answer: B

Rationale: The correct answer is B. A serum calcium level of 18 mg/dL is significantly elevated, posing a high risk for cardiac dysrhythmias. Immediate action is required to initiate cardiac monitoring and notify the healthcare provider. While the abnormalities in arterial blood pH, serum potassium, and arterial oxygen saturation also need attention, they are not as immediately life-threatening as the critically high serum calcium level. Therefore, addressing the serum calcium level takes precedence in this scenario.
