A nurse is studying the differences between normal cells and benign tumor cells. What information is included in this?

Benign tumors have lost their cellular regulation from contact inhibition.

Benign tumors typically grow in the wrong place or at the wrong time.

Benign tumors grow through invasion of other tissue.

The loss of characteristics of the parent cells is referred to as anaplasia.

Answer and Explanation

The Correct Answer is B

Choice B rationale:
Benign tumors typically grow in the wrong place or at the wrong time. This is a key distinguishing feature of benign tumors compared to normal cells. Normal cells have precise mechanisms that control their growth, ensuring they divide and multiply only when and where they are needed. Benign tumors, however, have disruptions in these regulatory mechanisms, leading to abnormal growth patterns. This means they may grow in locations where they don't belong or continue to grow even when they are no longer needed.
Here's a detailed explanation of why the other choices are incorrect:
Choice A:
Benign tumors have not lost their cellular regulation from contact inhibition. Contact inhibition is a process that stops normal cells from growing when they come into contact with other cells. Benign tumors still maintain this ability, which helps to limit their growth and prevent them from spreading to other tissues.
Choice C:
Benign tumors do not grow through invasion of other tissue. Invasion is a hallmark feature of malignant tumors (cancers). Benign tumors, on the other hand, typically grow as encapsulated masses, meaning they are surrounded by a well-defined border that separates them from surrounding tissues. They do not infiltrate or invade surrounding structures.
Choice D:
Anaplasia refers to the loss of differentiation and resemblance to the parent cells, which is a characteristic of malignant tumors, not benign tumors. Benign tumors still maintain a degree of differentiation, meaning they retain some of the characteristics of the normal cells from which they originated.

Correct Answer is C

Explanation

Choice A rationale:
While providing information about post-operative care and pain management is important, it may not directly address the patient's underlying anxiety or encourage them to express their concerns.
It could be perceived as dismissive of their feelings or as an attempt to control the conversation. It focuses on the future rather than the patient's present experience.
Choice B rationale:
This response, while intended to be reassuring, may minimize the patient's individual experience and feelings. It could make the patient feel as though their concerns are not being taken seriously.
It implies that anxiety is a normal and expected reaction, which may discourage the patient from sharing their specific worries.
Choice C rationale:
This response is open-ended and invites the patient to share their thoughts and feelings.
It demonstrates active listening and encourages the patient to take an active role in the conversation.
It allows the nurse to assess the patient's understanding of the surgery and to address any misconceptions or concerns. It conveys a sense of empathy and understanding, which can help to build trust and rapport with the patient.
Choice D rationale:
While offering to explain the procedure may be helpful, it may not be what the patient needs at the moment. It could overwhelm the patient with information, particularly if they are already feeling anxious.
It could shift the focus away from the patient's emotional needs and onto the technical aspects of the surgery.

A. Wear a respirator when handling urine output. B. Limit visitors strictly to immediate family members only. C. Wash hands only after removing gloves post-care. D. Prepare to administer vancomycin.

Correct Answer is D

Explanation

Choice A rationale:
Wearing a respirator when handling urine output is not routinely recommended for MRSA infections. While airborne transmission of MRSA is possible, it is primarily spread through direct contact with infected skin or surfaces. Respirators are typically reserved for situations where there is a high risk of aerosolization, such as during certain medical procedures.
The use of a respirator can be cumbersome and uncomfortable, and it may not provide significant additional protection in this context.

It's important to prioritize hand hygiene and contact precautions over respirator use for routine care of patients with MRSA infections.
Choice B rationale:
Limiting visitors strictly to immediate family members only is not necessary for MRSA infection control. Visitors can be educated on proper hand hygiene and contact precautions to minimize the risk of transmission.
Restricting visitors can have negative psychosocial impacts on the patient, such as isolation and decreased social support. It's important to balance infection control measures with the patient's overall well-being.
Choice C rationale:
Washing hands only after removing gloves post-care is inadequate for MRSA infection control. Hands should be washed thoroughly with soap and water or an alcohol-based hand sanitizer:
Before and after entering the patient's room
Before and after any contact with the patient or their surroundings After removing gloves
After using the toilet Before eating or drinking.

Choice D rationale:
Vancomycin is an antibiotic that is effective against MRSA infections. It is often the first-line treatment for these infections.
Preparing to administer vancomycin as prescribed by the healthcare provider is the most appropriate action to take to address the patient's MRSA infection.
Prompt initiation of appropriate antibiotic therapy is essential to controlling the infection and preventing complications.
