Final Answer:
A "shift to the left" in a complete blood count (CBC) signifies an increased number of immature white blood cells, triggering an elevated temperature as the body's response to combat infection or inflammation.
So, c. Elevated temperature is correct option.
Step-by-step explanation:
When a complete blood count (CBC) shows a "shift to the left," it indicates an increase in the number of immature white blood cells, often seen in response to infection or inflammation.
This elevation triggers the release of pyrogens, substances that reset the body's temperature regulatory center in the hypothalamus. Consequently, the nurse should expect an elevated temperature as the body's natural response to combatting infection or inflammation.
The term "shift to the left" refers to an increased number of immature or band forms of neutrophils, indicating an acute inflammatory process. Neutrophils are a type of white blood cell responsible for fighting infection.
An elevation in their immature forms suggests the body's heightened immune response. With an elevated immune response, the body initiates various defense mechanisms, including fever, to combat the underlying infection or inflammatory process.
Fever is a cardinal sign of infection or inflammation. It's a protective response where the body raises its temperature to create an unfavorable environment for pathogens, thus aiding in their destruction.
Therefore, in a patient with a CBC indicating a shift to the left, the nurse should anticipate an elevated temperature as the body actively fights off the underlying cause, whether it's an infection or an inflammatory condition.
So, c. Elevated temperature is correct option.
