When taking blood samples from an AIDS patient. Which precaution should be taken to collect blood sample according to guidelines?

Appeared in: PGIMER NO - 2020

Explanation

  • This option includes all the necessary components for full barrier protection under Standard Precautions.
  • Hand washing is the most fundamental step in infection control, which is included in this option.
  • A gown and mask provide additional layers of protection against potential splashes or sprays of blood, which is a prudent measure when dealing with a known bloodborne pathogen like HIV.
  • The combination of hand washing, gown, mask, and gloves ensures the highest level of safety for the healthcare provider during a procedure with risk of blood exposure.

Why Other Options Were Wrong

  • Option A: This option is incomplete as it omits hand washing, which is the most crucial first step in any infection control procedure.
  • Option B: Sterile gloves are not required for a routine blood draw (phlebotomy). Clean, non-sterile gloves are the standard. Sterile gloves are reserved for invasive procedures that breach sterile body cavities.
  • Option D: This option is incomplete. While gloves are essential, it omits hand washing, which must be performed before applying and after removing gloves.

Clinical Relevance
  • Nursing practice connection: Use the key finding related to Standard Precautions and Personal Protective Equipment (PPE) to guide bedside assessment, documentation, and the next nursing action.
  • The core principle of Standard Precautions is to treat all blood, body fluids, non-intact skin, and mucous membranes as if they are infectious, regardless of the patient's known diagnosis. This protects both the healthcare worker and other patients.
  • In India, the National AIDS Control Organisation (NACO) guidelines emphasize strict adherence to Universal Precautions (an older term for Standard Precautions) in all healthcare settings to prevent occupational exposure to HIV.
  • What if? If the procedure involved a high likelihood of aerosol generation (e.g., bronchoscopy on a patient with respiratory symptoms), the PPE requirement would escalate to include an N95 respirator in addition to other precautions.
How to Approach the Question
  • First, identify the core procedure: collecting a blood sample.
  • Next, note the specific patient context: a patient with AIDS, which confirms the presence of a bloodborne pathogen.
  • Recall the principles of Standard Precautions, which are designed for handling blood and body fluids.
  • Evaluate each option based on the essential components of infection control. Immediately eliminate any option that omits hand washing.
  • Compare the remaining options. Recognize that while minimum PPE for routine phlebotomy is gloves, the question asks for precautions according to guidelines for a high-risk pathogen. The most comprehensive option that ensures maximum safety is often the intended correct answer in such scenarios.
  • Select the option that provides the most complete barrier protection, including hand hygiene.
