A nurse is reviewing the documentation of a client's blood pressure by a newly licensed nurse.
The documentation states, "Blood pressure 102/58 mm Hg, client sitting up in a chair.”. Which of the following information should the nurse clarify?

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.

Choice A rationale:

Ensuring that the television is on is not a recommended action when providing discharge teaching for an adolescent with a cognitive disorder and their parents. Television noise can be distracting and may hinder effective communication. The focus should be on clear, concise, and tailored communication to address the patient's and family's needs.

Choice B rationale:

Using short directive statements is a suitable approach when teaching a patient with a cognitive disorder and their parents. Patients with cognitive disorders may have difficulty processing complex information, so using concise and straightforward language can enhance understanding. It is essential to adapt teaching strategies to the individual's needs and abilities.

Choice C rationale:

Including medical slang in the teaching is not appropriate, as it can confuse and alienate patients and their families. The goal of discharge teaching is to ensure that the information provided is clear, easily understood, and accessible to the patient and their family. Using medical jargon or slang may hinder this objective.

Choice D rationale:

Including abstract imagery is not recommended when teaching a patient with a cognitive disorder. Abstract imagery can be challenging to understand, especially for individuals with cognitive impairments. Teaching materials should be concrete, straightforward, and tailored to the patient's cognitive abilities and comprehension levels.
