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 C
Explanation
Choice A rationale:
Planning activities to prevent fatigue is a valid self-care strategy for SLE patients. Fatigue is a common symptom of SLE, and it can be exacerbated by overexertion. By planning activities and pacing themselves, patients can help to manage their fatigue and conserve energy.
Fatigue management strategies include:
Prioritizing tasks and delegating when possible.
Breaking down large tasks into smaller, more manageable ones. Taking frequent rest breaks throughout the day.
Maintaining a regular sleep schedule. Engaging in moderate exercise, as tolerated.
Avoiding caffeine and alcohol, which can interfere with sleep.
Addressing any underlying health conditions that may be contributing to fatigue, such as anemia or depression.
Choice B rationale:
Prioritizing rest is another essential self-care strategy for SLE patients. Rest allows the body to conserve energy and repair itself. Patients with SLE may need more rest than healthy individuals, especially during flares.
Resting strategies include:
Getting enough sleep at night. Napping during the day, as needed.
Taking breaks from activities throughout the day.
Practicing relaxation techniques, such as deep breathing or meditation.
Choice C rationale:
Sunbathing is not recommended for SLE patients, as it can trigger flares. Ultraviolet (UV) radiation from the sun can damage skin cells and exacerbate inflammation in SLE patients. This can lead to a flare-up of symptoms, such as skin rash, joint pain, and fatigue.
Sun protection strategies include:
Avoiding direct sunlight, especially during the middle of the day when UV rays are strongest. Wearing protective clothing, such as long-sleeved shirts, pants, and wide-brimmed hats.
Using sunscreen with an SPF of 30 or higher on a daily basis.
Applying sunscreen liberally and reapplying it every two hours, or more often if sweating or swimming.
Choice D rationale:
Avoiding direct sunlight is a correct self-care strategy for SLE patients.
Correct Answer is B
Explanation
Choice A rationale:
While promptly removing urinary catheters can reduce the risk of catheter-associated urinary tract infections (CAUTIs), it addresses only one specific type of infection. It doesn't comprehensively address other common healthcare-associated infections (HAIs) like central line-associated bloodstream infections (CLABSIs), surgical site infections (SSIs), ventilator-associated pneumonia (VAP), and Clostridium difficile infections (CDI).
Education about infection control methods, however, encompasses a broader range of preventive measures that can be applied to various HAIs, making it a more effective strategy for overall infection prevention.
Choice C rationale:
Placing patients in appropriate isolation can prevent the spread of infections, but it's a reactive measure that's implemented after an infection has already occurred. It doesn't address the root causes of infections or prevent their occurrence in the first place.
Education about infection control methods, on the other hand, is a proactive approach that aims to prevent infections from happening in the first place by teaching staff about proper hygiene practices, aseptic techniques, and other infection prevention strategies.
Choice D rationale:
Monitoring hand hygiene practices is crucial for infection prevention, but it's only one aspect of a comprehensive infection control program. Education about infection control methods goes beyond hand hygiene and covers various other preventive measures, such as:
Proper use of personal protective equipment (PPE) Aseptic technique during invasive procedures
Proper cleaning and disinfection of equipment and surfaces Proper handling of patient waste
Recognition of signs and symptoms of infection Prompt reporting of potential outbreaks
Therefore, educating staff members about infection control methods is the most effective action the nursing manager can take to prevent infections in the hospital unit because it provides a comprehensive approach to infection prevention, addressing various aspects of HAI prevention and promoting a culture of safety among healthcare staff.
