Question 1 of 5
A nurse is reviewing the laboratory findings for a client who developed fat embolism syndrome (FES) following a fracture. Which of the following laboratory findings should the nurse expect?
Correct Answer: B
Rationale: The correct answer is B: Decreased serum calcium level. In fat embolism syndrome (FES), fat globules enter the bloodstream, leading to blockages in small blood vessels. This can cause a decrease in serum calcium due to the formation of fat emboli in the pulmonary circulation, leading to hypoxia and subsequent release of inflammatory mediators that can affect calcium levels. The other choices are incorrect because in FES, there is no direct effect on serum calcium levels. Increased serum calcium levels (choice
A) are not expected in FES. While increased white blood cell count (choice
C) and decreased platelet count (choice
D) can occur in response to inflammation or infection associated with FES, they are not specific laboratory findings for FES.
