A nurse is learning the difference between normal cells and benign tumor cells. What information does this include?
Benign tumors have lost their cellular regulation from contact inhibition.
Growing in the wrong place or time is typical of benign tumors.
Benign tumors grow through invasion of other tissue.
The loss of characteristics of the parent cells is called anaplasia.
The Correct Answer is B
Choice A rationale:
Contact inhibition is a normal mechanism that regulates cell growth. When normal cells come into contact with each other, they stop growing. This prevents uncontrolled growth and the formation of tumors.
Benign tumor cells do not typically lose contact inhibition. They still respond to contact signals from neighboring cells and stop growing when they come into contact with each other.
However, they may grow in an uncontrolled manner due to other factors, such as mutations in genes that regulate cell growth.
Choice C rationale:
Invasion is a characteristic of malignant (cancerous) tumors, not benign tumors. Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body.
Benign tumors, on the other hand, are localized and do not invade surrounding tissues. They may grow and compress nearby tissues, but they do not spread.
Choice D rationale:
Anaplasia is a term used to describe the loss of differentiation of cells in a tumor. This means that the cells no longer resemble the normal cells from which they originated.
Anaplasia is a characteristic of malignant tumors, not benign tumors. Benign tumor cells typically retain some of the characteristics of the parent cells.

Correct Answer is A
Explanation
Rationale for Choice A:
A shift to the left in the white blood cell (WBC) count indicates an increased presence of immature neutrophils, known as bands. This is a hallmark sign of infection, as the body is rapidly producing and releasing these cells to fight off invading pathogens.
Prompt notification of the primary health care provider is crucial to initiate timely antibiotic therapy, if indicated. Early intervention with appropriate antibiotics can effectively combat the infection, prevent its progression, and potentially avert serious complications.
Delaying antibiotic treatment can allow the infection to worsen, potentially leading to sepsis, septic shock, or other life- threatening conditions.
Rationale for Choice B:
While informing the client about the significance of a shift to the left is important for education and understanding, it does not address the immediate need for medical intervention.
The priority action is to involve the primary health care provider for prompt assessment and potential initiation of antibiotic therapy.
Rationale for Choice C:
Documenting findings and continuing to monitor the client's condition is essential for ongoing assessment and evaluation, but it does not constitute a proactive intervention to address the underlying infection.
Documentation alone does not initiate treatment, and monitoring without intervention risks allowing the infection to progress.
Rationale for Choice D:
Protective isolation is not routinely indicated for clients with a shift to the left in their WBC count unless there is a specific concern for transmission of a highly contagious infection.
The decision to implement protective isolation measures would be based on the client's overall clinical presentation and potential infectious risks, as determined by the primary health care provider.
