TEST questions and
answers
A nursing student is caring for a patient who is at risk for shock.
The student asks, "Which laboratory results should I monitor to
see if shock has developed?" How should the instructor
respond?
Shock is a complex condition with various manifestations and
requires monitoring of multiple laboratory results."
-CBC, DIC, cardiac enzymes, creatinine, GFR, BUN, electrolytes,
ABGs, cultures, liver enzymes (one test alone is not enough to
monitor development of shock)
The nurse is caring for a patient who is being treated for shock.
Initial laboratory results show elevated white blood cell (WBC)
counts and an elevated procalcitonin (PCT) level. What do these
laboratory results indicate?
,The patient has shock caused by a systemic bacterial infection.
- An elevated WBC count indicates an infection, and PCT is a
biomarker released in response to a bacterial infection.
