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.

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.
