Select the 3 findings that require immediate follow-up.

The correct answer is Choice A, Choice B

Choice A rationale: Clostridium difficile is a spore-forming, gram-positive anaerobic bacillus that causes antibiotic-associated colitis. Transmission occurs via the fecal-oral route, primarily through contact with contaminated surfaces or hands. Protective gowns are essential during care to prevent spore transfer to clothing and subsequent environmental contamination. Spores resist alcohol-based sanitizers and persist on surfaces for months. Contact precautions, including gown use, reduce nosocomial spread. Normal white blood cell count is 4,000–11,000/mm³; elevated levels may indicate infection severity.

Choice B rationale: Isolation in a private room is critical for clients with confirmed Clostridium difficile infection due to the organism’s ability to form resilient spores that contaminate surfaces and equipment. Private rooms limit environmental exposure and reduce cross-contamination risk. C. difficile spores are resistant to routine cleaning agents and require bleach-based disinfectants. Diarrheal stool volume increases transmission risk. Normal stool frequency is 1–3 formed stools/day; 4–5 liquid stools/day indicates active infectious diarrhea requiring isolation.

Choice C rationale: N-95 respirators are designed for airborne pathogens such as Mycobacterium tuberculosis, measles virus, or varicella-zoster virus. Clostridium difficile is not airborne; it transmits via contact with contaminated surfaces or hands. Spores are shed in feces and do not aerosolize under normal conditions. Therefore, N-95 respirators offer no added protection against CDI. Airborne precautions are unnecessary unless aerosol-generating procedures are performed on patients with concurrent airborne infections. Respiratory rate normal range is 12–20 breaths/min.

Choice D rationale: Negative pressure rooms are used to contain airborne pathogens by maintaining lower air pressure inside the room, preventing contaminated air from escaping. Clostridium difficile does not spread via airborne particles but through contact with contaminated surfaces and feces. Thus, negative pressure rooms are not scientifically justified for CDI. Instead, contact isolation and environmental decontamination are prioritized. Room air exchanges are irrelevant to CDI control. Normal room air pressure is neutral unless airborne precautions are indicated.

Choice E rationale: Masking the client is a droplet precaution used for pathogens like influenza virus, Neisseria meningitidis, or SARS-CoV-2. Clostridium difficile does not transmit via respiratory droplets, so placing a mask on the client during transport does not reduce transmission risk. Instead, hand hygiene and contact precautions are essential. CDI spores are not expelled via coughing or sneezing. Droplet precautions are reserved for pathogens with particle size >5 µm. Normal oxygen saturation is ≥95% on room air.

The correct answer is Choice A.

Choice A rationale: Using a cell phone to request assistance from the client's room ensures timely communication and enhances patient care. Quick access to help can be vital in emergency situations, ensuring prompt and effective intervention.

Choice B rationale: Sending a personal text to a co-worker during work hours is unprofessional and can lead to distractions. It can compromise patient care and violates workplace policies on personal device usage, ensuring focus remains on patient safety and care.

Choice C rationale: Calling the client's family member per their request can violate privacy and confidentiality regulations, such as HIPAA in the US. Communication with family should go through proper channels to ensure compliance with legal and ethical standards.

Choice D rationale: Taking a photo of a client's incision site for learning purposes without proper consent and documentation breaches patient confidentiality and privacy. It could also result in legal ramifications and violates institutional policies on using personal devices for work-related tasks.
