Question

Which of the following preoperative lab values must be reported immediately to the surgeon?

a.Creatinine: 1.2 mg/dL(106.1 umol/l)
b.Hemoglobin: 14.8 mg/dL (148 mmol/L)
c.Sodium: 134 mEq/L (134 mmol/l)
d.Potassium: 2.9 mEq/L (2.9 mmol/l)

Answer 1

A potassium level of 2.9 mEq/L (2.9 mmol/l) must be reported immediately to the surgeon.

Step-by-step explanation:

The preoperative lab value that must be reported immediately to the surgeon is a potassium level of 2.9 mEq/L (2.9 mmol/l).

Potassium is an essential electrolyte that plays a crucial role in the functioning of the heart, muscles, and nerves. A potassium level of 2.9 mEq/L is below the normal range of 3.5-5.0 mEq/L, indicating hypokalemia (low potassium levels).

Hypokalemia can cause irregular heart rhythms, muscle weakness, and other serious complications. Therefore, the surgeon should be immediately informed to take appropriate actions.
