Explanation

A White Blood Cell (WBC) count of 3,000/mm³ is below the normal range of 4,500-11,000/mm³, a condition called leukopenia.
Leukopenia severely compromises the patient's ability to fight infection, making them highly vulnerable to pathogens from the environment.
Protective precautions (also called neutropenic precautions or reverse isolation) are specifically designed to create a barrier between the immunocompromised patient and potential pathogens.
This type of precaution focuses on protecting the patient from others, unlike other precautions that aim to prevent the spread of infection from the patient.

Option B: "Airway precaution" is not a standard, recognized category in infection control guidelines. The closest standard term is "Airborne Precautions," which is used for different pathogens.
Option C: Droplet precautions are used to prevent the transmission of pathogens spread through large respiratory droplets from an infected patient to others.
Option D: Enteric precautions are a form of Contact precautions used for infections spread through the fecal-oral route. They aim to prevent the spread of germs from the patient's gastrointestinal tract.

Clinical Relevance

Nursing practice connection: Knowing Infection control precautions for immunocompromised patients helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses are responsible for initiating and maintaining appropriate isolation precautions to ensure patient safety. For a neutropenic patient, this is a critical life-saving intervention.
Strict adherence to protective precautions, including meticulous hand hygiene, screening visitors for illness, and providing a controlled environment, directly reduces the risk of sepsis and death in immunocompromised patients.
What if? If the patient's WBC count was normal (e.g., 8,000/mm³) but they had symptoms of influenza (fever, cough), the correct action would be to initiate Droplet Precautions, not Protective Precautions.

How to Approach the Question

First, analyze the clinical data provided in the question: "WBC count of 3000".
Recall the normal range for WBCs (4,500-11,000/mm³). Recognize that 3,000 is low (leukopenia/neutropenia).
Understand the implication of a low WBC count: the patient is immunocompromised and at high risk for infection.
Evaluate the options based on the goal. The goal is to prevent infection in the patient. This points towards precautions that protect the patient from the environment.
Differentiate between precautions that protect the patient (Protective) and those that protect others from the patient (Contact, Droplet, Airborne).
Select 'Protective precaution' as it is the only option designed to shield a vulnerable patient from external pathogens.
