### Transmission-Based Precautions
QUESTION: The nurse is caring for a patient who has been
diagnosed with methicillin-resistant Staphylococcus aureus located in her incision. What transmission-based precautions will the nurse implement for the patient?
- Private room
- Private, negative-airflow room
- Mask worn by the staff when entering the room
- Mask worn by the staff and the patient when leaving the
patient's room
Answer: A
Rationale: From the provided text under "contact precautions,"
MRSA is identified as an infection requiring contact precautions, which include a private room, wearing gloves and gown at all times when in contact with the patient or their environment, and other measures like containing the infected area and using dedicated equipment. A private room (option a) is explicitly listed as a contact precaution practice. A negative- airflow room (option b) is associated with airborne precautions (e.g., tuberculosis), not MRSA. Masks (options c and d) are not

required for contact precautions unless specified for other reasons, such as droplet transmission, which is not indicated for MRSA here.
QUESTION: A new patient is admitted to a medical unit with
Clostridioides difficile. Which type of precautions or isolation does the nurse know is appropriate for this patient?
- Airborne precautions
- Droplet precautions
- Contact precautions
- Protective isolation
Answer: C
Rationale: From the provided text, "contact precautions"
explicitly list C. Diff (Clostridioides difficile) as an infection requiring this type of precaution. Contact precautions involve a private room, gloves and gown, and other measures like using disposable or dedicated equipment. Airborne precautions (option a) are for infections like tuberculosis, transmitted via air currents. Droplet precautions (option b) apply to infections spread by respiratory droplets (e.g., influenza), not C. Diff.Protective isolation (option d) is not mentioned in the text but typically refers to protecting immunocompromised patients, not managing infectious spread like C. Diff.

### Patient Education and Infection Definition
QUESTION: The nurse is providing patient education on
infection prevention. Which definition of an infection does the nurse use as a teaching point?
- An illness resulting from living in an unclean environment
- A result of lack of knowledge about food preparation
- A disease resulting from pathogens in or on the body
- An acute or chronic illness resulting from traumatic injury
Answer: C
Rationale: The text does not explicitly define "infection" in a
single statement, but under "Infectious Agent," it describes an infectious agent as a pathogen that causes disease, and throughout the document (e.g., "Bacteria," "Viruses," "Fungi," "Parasites"), infections are consistently linked to pathogens.Option c ("A disease resulting from pathogens in or on the body") aligns with this understanding. Option a is too narrow, focusing only on environment; option b limits it to food preparation knowledge; and option d ties infection to trauma, which is not the primary focus of the provided infection-related content.

### Causative Agents of Infection
QUESTION: The nurse is caring for a patient who had
abdominal surgery and has developed an infection in the wound while hospitalized. Which agent is most likely the cause of the infection?
- Virus
- Bacterium
- Fungus
- Spore
Answer: B
Rationale: The text under "Surgical site infection" describes
signs like redness, warmth, purulent drainage, tenderness, and localized pain, which are consistent with bacterial infections, particularly in a healthcare-associated context. "Bacteria" are described as pathogens capable of causing disease when they overgrow or enter different body areas, and healthcare- associated infections (HAIs) like surgical site infections are often bacterial (e.g., MRSA, C. Diff). Viruses (option a) typically cause systemic or respiratory infections, not localized wound infections. Fungi (option c) are linked to conditions like athlete’s foot or yeast infections, less common in surgical wounds. Spores (option d) are not a distinct agent category in the text but are part of bacterial or fungal life cycles, not a primary cause.
