Zorluk: Çok zorStandard and Transmission-Based Precautions

A hematopoietic stem cell transplant recipient with an absolute neutrophil count (ANC) of 150 cells/μL150 \text{ cells}/\mu\text{L} develops sudden, copious, foul-smelling liquid stools. The provider suspects an infectious enterocolitis, and stool polymerase chain reaction (PCR) assays are pending. As the clinical team coordinates the client's ongoing care, which of the following interventions are appropriate for this specific presentation? Select all that apply.

  1. Cleanse hands thoroughly with soap and water for at least 20 seconds immediately after removing personal protective equipment.Cevap
  2. B
    Disinfect dedicated, reusable medical equipment, such as a stethoscope, with a quaternary ammonium-based germicidal wipe after use.
  3. Prohibit the delivery of fresh floral arrangements and raw, unpeeled produce to the client's room.Cevap
  4. Don a clean, disposable gown and non-sterile gloves immediately prior to crossing the threshold into the client's room.Cevap
  5. E
    Assign the unlicensed assistive personnel (UAP) to evaluate the client's perianal skin for excoriation during routine hygiene care.
  6. F
    Transfer the client to an airborne infection isolation room (AIIR) with negative-pressure airflow to contain the suspected pathogen.

Cevap

The correct interventions are cleansing hands thoroughly with soap and water after removing personal protective equipment, prohibiting fresh floral arrangements and raw produce, and donning a clean gown and gloves prior to entering the room.
The proper management of this complex scenario requires a synthesis of a Protective Environment (neutropenic precautions) and Contact Enteric precautions. The client's severe neutropenia mandates the restriction of pathogen-harboring items such as fresh plants and raw produce. Simultaneously, the highly suspicious presentation of C. difficile requires the immediate application of barrier precautions (donning gown and gloves before room entry) to prevent fomite spread, and the use of soap and water for hand hygiene, as the mechanical friction is necessary to wash away alcohol-resistant bacterial spores.

Adım Adım Çözüm

1
Analyze the client's immune status based on the provided laboratory data.
An absolute neutrophil count (ANC) of 150 cells/μL indicates severe neutropenia.
This establishes the need for a Protective Environment to shield the client from exogenous, opportunistic infections.
2
Analyze the client's new clinical symptoms.
Sudden, copious, foul-smelling liquid stools following a transplant highly suggest Clostridioides difficile enterocolitis.
This establishes the immediate need for Contact Enteric precautions to protect staff and the hospital environment, even while diagnostic assays are pending.
3
Synthesize necessary protective measures for severe neutropenia.
Eliminate vectors for environmental pathogens (e.g., fresh flowers, unpeeled fruits) and ensure the client is in a positive-pressure or standard private room, avoiding negative-pressure environments.
Live plants and raw produce harbor bacteria and fungi; negative pressure would actively pull hallway pathogens into the immunocompromised client's room.
4
Synthesize necessary isolation measures for suspected C. difficile.
Identify that spore-forming bacteria require mechanical removal via soap and water (alcohol is ineffective), disinfection with bleach (sporicidal), and barrier protection (gown and gloves) upon entry.
These specific interventions halt the fecal-oral and fomite transmission routes typical of enteric spores.
5
Evaluate the nursing delegation options.
Determine that evaluating perianal skin integrity is an assessment.
Assessments cannot be delegated to unlicensed assistive personnel (UAP).
