Question

The nurse is reviewing a client's laboratory report and notes that the total serum calcium level is 6.0 mg/dL (1.66 mmol/L). The nurse understands that which condition most likely caused this serum calcium level?

a) Hypercalcemia
b) Hypocalcemia
c) Hyperkalemia
d) Hypokalemia

Answer 1

Given the serum calcium level of 6.0 mg/dL, the condition most likely causing this result is hypocalcemia, which features abnormally low levels of calcium in the blood.

Step-by-step explanation:

The nurse noted that the total serum calcium level is 6.0 mg/dL (1.66 mmol/L). Given that the normal blood calcium level is approximately 9.5-10.5 mg/100 ml (or 9.5-10.5 mg/dL), this lab result suggests a condition known as hypocalcemia. Hypocalcemia is characterized by abnormally low calcium blood levels, which can result in issues with blood coagulation, muscle contraction, nerve functioning, and bone strength. It is imperative to note that hypercalcemia indicates abnormally high calcium levels, while hyperkalemia and hypokalemia refer to potassium imbalances, not calcium. Therefore, the correct answer to the question is (b) Hypocalcemia, which most likely caused this serum calcium level.
