Question

Difficulty: Very hardStandard and Transmission-Based Precautions

During the morning shift, a nurse is assigned to a client undergoing treatment for active pulmonary tuberculosis who has newly developed frequent, watery stools. The healthcare provider suspects a Clostridioides difficile infection. Which infection control interventions must the nurse implement? (Select all that apply.)

  1. Don an N95 respirator, a fluid-resistant gown, and gloves prior to entering the client's negative-pressure room.Answer
  2. B
    Perform hand hygiene using an alcohol-based hand rub immediately after exiting the room.
  3. C
    Remove the N95 respirator inside the client's room immediately after doffing the gown and gloves.
  4. Ensure the client wears a standard surgical mask if transport outside the negative-pressure room is necessary.Answer
  5. Retain dedicated vital sign equipment, such as a stethoscope and thermometer, exclusively inside the client's room.Answer
  6. F
    Request reassignment of the client to a registered nurse, as dual isolation requirements exceed the practical nursing scope of practice.

Answer

The nurse must don an N95 respirator, gown, and gloves prior to entry; ensure the client wears a surgical mask during transport; and keep dedicated vital sign equipment in the room.
The combination of tuberculosis and suspected C. difficile necessitates both airborne and contact precautions. This means the nurse must don an N95 respirator, gown, and gloves before entry. Dedicated equipment must remain in the room to prevent contact transmission, and the client must wear a standard surgical mask during transport to prevent airborne transmission.

Step-by-Step Solution

1
Identify the primary transmission routes for the two conditions.
Tuberculosis requires airborne precautions; Clostridioides difficile requires contact precautions.
Determining the required isolation categories dictates the necessary personal protective equipment (PPE) and environmental controls.
2
Determine the appropriate PPE for entering the room.
An N95 respirator is needed for airborne precautions, and a gown and gloves are needed for contact precautions.
All required PPE must be donned before crossing the threshold to prevent exposure.
3
Evaluate the hand hygiene requirements for the suspected pathogen.
Soap and water must be used.
C. difficile forms spores that are resistant to alcohol-based hand rubs and must be physically washed away.
4
Assess the sequence for PPE removal.
The N95 respirator must be removed after leaving the room.
Removing the respirator inside the room exposes the nurse to airborne droplets of Mycobacterium tuberculosis.
5
Review transport and equipment guidelines.
The client must wear a surgical mask during transport, and equipment must be dedicated to the room.
These measures prevent the spread of both airborne droplets and contact spores to the hospital environment.
