A nurse is reinforcing teaching with new parents about the provider's prescription for a serum bilirubin test. Which of the following statements should the nurse include in the explanation?

Methicillin-resistant Staphylococcus aureus (MRSA) is a highly resistant bacterial infection transmitted primarily through direct contact with contaminated hands, surfaces, or equipment. Medical asepsis focuses on reducing and preventing the spread of microorganisms through proper hygiene and infection-control practices. Hand hygiene remains the single most effective intervention for preventing transmission of MRSA in healthcare settings. Nurses must consistently apply standard and contact precautions to protect both clients and healthcare personnel.

Rationale:
A. Wearing a mask while providing activities of daily living is not routinely required for MRSA because the organism is primarily spread through contact rather than airborne transmission. Masks are generally reserved for procedures that may generate respiratory droplets or if the client has a concurrent respiratory infection. Contact precautions focus more on gloves, gowns, and hand hygiene.

B. Washing hands for at least 15 seconds before providing care is correct because effective hand hygiene significantly reduces transmission of MRSA between clients and healthcare workers. Proper washing removes transient organisms from the skin and interrupts contact spread. Hand hygiene should be performed before and after client contact and after glove removal.

C. Using a 40% alcohol-based hand product is incorrect because alcohol-based hand rubs should contain at least 60% alcohol to effectively reduce microbial contamination. Lower concentrations are less effective against many pathogens and do not meet recommended infection-control standards.

D. Providing the client with a mask during clinical visits is not routinely necessary for MRSA because transmission occurs mainly through direct contact, not respiratory droplets. Masks are more appropriate for airborne or droplet precautions. Contact isolation measures are the priority for MRSA management.

Workplace violence and active threat situations require immediate actions focused on personal safety, de-escalation avoidance, and rapid protection from harm. In the presence of an armed, agitated individual, nursing priorities shift from patient care to survival strategies consistent with emergency safety protocols. Standard guidance emphasizes avoiding confrontation, minimizing visibility, and seeking secure shelter until law enforcement intervenes. Understanding appropriate responses reduces risk of injury or fatality in high-risk events.

Rationale:
A. Keeping doors unlocked is unsafe because it increases accessibility to staff and patients, allowing the armed individual to move freely through the unit. In an active threat situation, securing barriers and limiting entry points is essential to reduce exposure. This action would increase risk rather than promote safety.

B. Increasing the ringer volume on cell phones is inappropriate and may increase the likelihood of detection by the aggressor. Noise can draw attention to staff locations, compromising concealment. In emergency safety situations, silence and minimizing stimuli are critical for survival.

C. Hiding out of sight is correct because it aligns with “run, hide, fight” safety principles used in active shooter or armed intruder scenarios. Remaining concealed reduces visibility and lowers the risk of being targeted by the individual. In situations involving immediate threat, prioritizing concealment and silence is essential for protection while awaiting law enforcement response.

D. Approaching the armed individual is extremely dangerous and not appropriate. Engaging or confronting an active threat increases the likelihood of injury or death. Nursing staff should avoid interaction and instead prioritize evacuation or concealment based on environmental safety.
