A nurse is caring for a patient with hepatitis B. Which action by the nurse demonstrates the most appropriate infection control practice?
1Wearing only gloves when handling the patient's blood specimens
2Using alcohol-based hand sanitizer instead of soap and water after patient contact
3Placing the patient in droplet precautions with a surgical mask
4Following standard precautions and treating all body fluids as potentially infectious✓ 정답
해설
Standard precautions are the foundation of infection control for hepatitis B, as it is transmitted through blood and body fluids. Other options are insufficient or inappropriate for hepatitis B transmission routes.
Core Nursing ExplanationKey Concept Analysis: This question tests the application of Standard Precautions for a patient with Hepatitis B (HBV). Hepatitis B is a bloodborne pathogen transmitted primarily through exposure to infected blood, semen, and other body fluids. The core principle of infection control is to apply the same level of protection to all patients, regardless of their known diagnosis, by treating all blood and certain body fluids as potentially infectious.
Answer Rationale: Key Point! Option ④ is correct because it directly states the fundamental rule of Standard Precautions. This approach is the most appropriate and comprehensive for Hepatitis B, as it mandates the use of personal protective equipment (PPE) like gloves, gowns, masks, and eye protection based on the anticipated exposure, not just the diagnosis. It protects the nurse from all potential sources of infection, including those that are not yet identified.
Distractor Analysis:
Option ①: Wearing only gloves is insufficient. Standard Precautions require assessing the task for potential splash or spray of body fluids. For handling blood specimens, gloves are essential, but if there is a risk of splashing, a gown, mask, and eye protection may also be necessary.
Option ②: While alcohol-based hand sanitizer is effective for many pathogens, Watch out for confusion! it is not sufficient when hands are visibly soiled or after caring for a patient with Clostridioides difficile (C. diff) or certain non-enveloped viruses. For Hepatitis B, soap and water or sanitizer are both acceptable, but the option implies a preference that isn't always correct and misses the broader point of Standard Precautions.
Option ③: This is incorrect for Hepatitis B. Droplet Precautions are for pathogens spread by large respiratory droplets over short distances (e.g., influenza, pertussis). Hepatitis B is not transmitted via the respiratory route; it is a bloodborne pathogen. Placing the patient in unnecessary isolation can cause psychological distress and is not evidence-based.
Related Concepts: This question integrates knowledge of disease transmission routes (bloodborne vs. airborne vs. droplet), the hierarchy of infection control measures (Standard vs. Transmission-Based Precautions), and the correct use of PPE. Understanding that Standard Precautions are the minimum level for all patient care is crucial.
Concept Summary
Concept
Description
Application to Hepatitis B
Standard Precautions
Minimum infection prevention practices for all patient care. Treat all blood, body fluids, secretions, excretions (except sweat), non-intact skin, and mucous membranes as potentially infectious.
Primary and mandatory approach. Use gloves for contact with blood/body fluids; add gown/mask/eye protection if splashing is possible.
Transmission-Based Precautions
Additional precautions used for patients with known or suspected infections spread by specific routes: Contact, Droplet, or Airborne.
Hepatitis B typically does not require these unless there is a risk of environmental contamination (e.g., incontinence) which would warrant Contact Precautions.
Bloodborne Pathogens
Microorganisms present in human blood that can cause disease (e.g., HBV, HCV, HIV).
HBV is a classic example. Transmission occurs via percutaneous injury, mucous membrane exposure, or sexual contact.

Precaution Type
Purpose & Pathogens
Key PPE & Actions
Standard Precautions
For all patients. Foundation for preventing transmission from both recognized and unrecognized sources.
PPE based on anticipated exposure: Gloves, with gown/mask/eye protection as needed. Hand hygiene.
Contact Precautions
For pathogens spread by direct or indirect contact (e.g., MRSA, VRE, C. diff).
Gloves and gown for all room entry. Dedicated equipment if possible.
Droplet Precautions (Option ③)
For pathogens spread by large droplets from cough/sneeze (e.g., influenza, pertussis, meningococcal meningitis).
Surgical mask for close contact. Patient should wear mask during transport.
Airborne Precautions
For pathogens spread by small airborne particles (e.g., tuberculosis, measles, chickenpox).
N95 respirator or PAPR. Patient in negative pressure room. Mask on patient during transport.
Anatomy, Physiology & Pharmacology Points
Pathophysiology: Hepatitis B virus infects hepatocytes (liver cells), causing inflammation. It is present in high concentrations in blood and serous fluids.
Transmission: Parenteral (needlesticks, sharps), mucosal (eyes, mouth), sexual, and perinatal. It is not spread through casual contact, food, water, or coughing/sneezing.
Prevention: Hepatitis B vaccine is the primary prevention. Post-exposure prophylaxis (PEP) with Hepatitis B Immune Globulin (HBIG) and vaccine is available for unprotected exposures.
Memory Tips
Standard for All: Remember "Standard Precautions are for Standard care of All patients."
HBV Transmission: Think "Blood and Body fluids" for Hepatitis B.
PPE Rule: Use the mnemonic "Glove Up Before Exposure" (Gown, Gloves, Mask, Eye protection) – but always base your choice on the task's exposure risk.
High-Frequency NCLEX Topics
Infection control, especially Standard Precautions, is a High Yield topic. The NCLEX-RN loves to test:
1. Selecting appropriate PPE for a given task (e.g., drawing blood, changing a dressing with drainage).
2. Differentiating between Standard and Transmission-Based Precautions based on disease symptoms.
3. Prioritizing nursing actions related to safety (e.g., donning PPE before entering a room).
Watch Out for Question Variations!
The same concept can be tested in many ways:
Priority Action: "The nurse enters the room of a patient with Hepatitis B who is vomiting blood. What should the nurse do first?" (Answer: Don appropriate PPE, likely gloves and a gown/face shield, before approaching).
Patient Education: "Which statement by a patient with Hepatitis B indicates understanding of transmission prevention?" (Correct answer focuses on safe sex practices and not sharing razors/toothbrushes).
Post-Exposure: "A nurse sustains a needlestick from a patient with Hepatitis B whose vaccination status is unknown. What is the priority action?" (Answer: Wash the site with soap and water, then follow facility protocol for reporting and PEP evaluation).
Nursing Clinical Practice GuideClinical Scenario: You are assigned to Mr. Chen, a 45-year-old admitted with complications from chronic Hepatitis B. He has an IV line, and you need to draw blood for liver function tests. The room is not on any special isolation.
Nursing Intervention Strategy:
Assessment & Planning: Before entering, review the order and gather supplies. Mentally assess the risk: drawing blood involves potential exposure to blood. Plan to use Standard Precautions.
Implementation:
Perform hand hygiene.
Don gloves. Since drawing blood from a central line or with a risk of spray is low, gloves may be sufficient. However, if the patient is uncooperative or you anticipate difficulty, consider also wearing a face shield.
Perform the blood draw using safe needle devices.
Dispose of the sharp immediately in a sharps container at the point of use.
Place blood tubes in a biohazard bag for transport.
Remove gloves and perform hand hygiene again.
Patient Education & Evaluation: Educate Mr. Chen that his routine care does not require special isolation, but staff will use gloves when handling his blood to protect everyone. Evaluate your technique: Was there any breach in technique? Was all contaminated waste disposed of properly?
Patient Safety and Precautions:
Sharps Safety: Never recap needles. Use safety-engineered devices.
Environmental Cleaning: If any blood is spilled on surfaces, clean with an EPA-approved disinfectant.
Laundry: Handle soiled linen with minimal agitation; place in leak-proof bags.
Nursing Procedure & Medication FlowBlood Draw under Standard Precautions:
1. Verify patient identity.
2. Perform hand hygiene.
3. Assemble equipment on a clean surface.
4. Don appropriate PPE (gloves are minimum for this task).
5. Perform venipuncture using aseptic technique.
6. Engage safety device on needle immediately after use.
7. Dispose of needle/syringe as a single unit in sharps container.
8. Label tubes at bedside.
9. Remove gloves and perform hand hygiene.
10. Transport specimens in a sealed biohazard bag.
A Word from Your Senior Nurse: "In the real world, 'Standard Precautions' is your best friend and your shield. It's easy to get complacent, especially with stable chronic patients like Mr. Chen. But remember, you never know what a patient might be carrying. That simple act of gloving up isn't just about protecting you from Hepatitis B; it's about protecting the next patient from anything you might carry on your hands. On the NCLEX and in practice, if you're ever unsure about what precautions to use, fall back on the basics: Standard Precautions are always right. Think about the task, not just the diagnosis. That mindset will keep you and your patients safe."
Standard Precautions — The minimum infection prevention practices that apply to all patient care, regardless of suspected or confirmed infection status. They are based on the principle that all blood, body fluids, secretions, excretions (except sweat), non-intact skin, and mucous membranes may contain transmissible infectious agents.
Hepatitis B — A viral infection that attacks the liver and can cause both acute and chronic disease. It is a bloodborne pathogen transmitted through contact with infectious blood or body fluids.
Bloodborne Pathogens — Pathogenic microorganisms that are present in human blood and can cause disease in humans. These pathogens include, but are not limited to, hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV).
Personal Protective Equipment — Specialized clothing or equipment worn by healthcare personnel for protection against infectious materials. Examples include gloves, gowns, masks, respirators, and eye protection.
Transmission-Based Precautions — Additional precautions used for patients who are known or suspected to be infected or colonized with infectious agents, including pathogens transmitted by contact, droplet, or airborne routes. They are used in addition to Standard Precautions.
