A nurse is caring for a 60-year-old patient with chronic hepatitis B infection. Which nursing intervention is the highest priority to prevent transmission to healthcare workers and other patients?
A 52-year-old patient is admitted to the medical unit with chronic hepatitis B infection. The patient presents with abdominal pain, dark urine, and mildly elevated liver enzymes. The nurse must implement appropriate safety measures to prevent transmission.
1Administer hepatitis B immunoglobulin (HBIG) to all staff members
2Place the patient in airborne precautions with negative pressure room
3Implement standard precautions and treat blood and bodily fluids properly✓ 정답
4Isolate the patient in a private room with contact precautions only
해설
Standard precautions and proper handling of blood/body fluids are the priority to prevent hepatitis B transmission, as it is bloodborne. Other options are unnecessary or incorrect for this infection.
Core Nursing ExplanationKey Concept Analysis: This question tests your knowledge of infection control for a patient with a bloodborne pathogen. Hepatitis B virus (HBV) is transmitted primarily through percutaneous or mucosal exposure to infectious blood or body fluids (e.g., semen, vaginal secretions). It is not transmitted via the airborne or droplet route. The cornerstone of preventing transmission in healthcare settings is the consistent application of Standard Precautions, which are designed to protect healthcare workers from all patients, regardless of their known infection status.
Answer Rationale: Key Point! Option ③ is correct because Standard Precautions are the fundamental, first-line, and most critical intervention for preventing transmission of bloodborne pathogens like HBV. This includes proper hand hygiene, use of personal protective equipment (PPE) like gloves and gowns when exposure to blood or body fluids is anticipated, safe handling of sharps, and proper disposal of contaminated materials. Since the patient has chronic hepatitis B, all blood and body fluids should be treated as potentially infectious.
Distractor Analysis:
Watch out for confusion! Option ①: Administering Hepatitis B Immunoglobulin (HBIG) to all staff is incorrect. HBIG is used for post-exposure prophylaxis after a specific incident (e.g., a needlestick injury from an HBV-positive source). It is not a routine preventive measure for all staff caring for the patient. Primary prevention for healthcare workers is vaccination.
Option ②: Placing the patient in airborne precautions is unnecessary and incorrect. Airborne precautions (with an N95 respirator and negative pressure room) are for diseases transmitted via small, airborne droplet nuclei that remain suspended in the air (e.g., tuberculosis, measles, chickenpox). HBV does not spread this way.
Option ④: Isolating the patient in a private room with contact precautions only is generally not required for standard care of hepatitis B. A private room is only indicated if the patient's hygiene is poor (e.g., incontinence, uncontained secretions) or there is a risk of environmental contamination. Contact precautions are primarily for pathogens spread by direct contact or contact with the patient's environment (e.g., MRSA, C. diff). For HBV, Standard Precautions are sufficient for routine care.
Related Concepts: Understanding the chain of infection is crucial. For HBV, the portal of exit is blood/body fluids, the mode of transmission is primarily percutaneous/mucosal, and the portal of entry for a healthcare worker is through a break in the skin or mucous membranes. Breaking this chain involves using barriers (PPE) and safe work practices (Standard Precautions).
Concept Summary
Concept
Key Takeaway
Hepatitis B Transmission
Bloodborne pathogen. Spread via contact with infectious blood, semen, vaginal fluids. Not airborne or via casual contact.
Standard Precautions
The foundational infection control practice. Applied to all patients. Includes hand hygiene, PPE, safe injection practices.
Transmission-Based Precautions
Used in addition to Standard Precautions for specific pathogens. Includes Contact, Droplet, Airborne.
Post-Exposure Prophylaxis (PEP)
For healthcare workers after an exposure (e.g., needlestick). May involve HBIG and/or HBV vaccine booster.

Pathophysiology: HBV attacks hepatocytes (liver cells), causing inflammation (hepatitis). Chronic infection can lead to cirrhosis and hepatocellular carcinoma.
Lab Values: Key serologic markers include HBsAg (indicates infection), HBeAg (indicates high viral replication/infectivity), and Anti-HBs (indicates immunity from vaccine or past infection). Elevated liver enzymes (ALT, AST) indicate active liver damage.
Pharmacology: HBIG provides temporary, passive immunity. The HBV vaccine provides active, long-term immunity and is the primary prevention strategy for healthcare workers.
Memory Tips
B is for Blood: Remember Hepatitis B is a Bloodborne pathogen.
Standard First!: Always start with Standard Precautions. Ask: "Is this pathogen spread by contact, droplet, or airborne routes in addition to blood/body fluids?" If not, Standard Precautions are enough.
Airborne vs. Bloodborne: Think "Air" vs. "Fluid." TB (airborne) needs a special room; HBV (bloodborne) needs gloves and safe sharps handling.
High-Frequency NCLEX Topics
NCLEX loves testing your ability to select the appropriate type of isolation/precaution for a given disease. Hepatitis B is a classic example to test if you know the difference between Standard and Transmission-Based Precautions. Expect questions that ask for the "priority" intervention or "necessary" precautions, often including distractors that over-isolate (e.g., airborne for a bloodborne pathogen) or under-protect.
Watch Out for Question Variations!
Shift from "Precautions" to "Patient Education": "The nurse is discharging a patient with chronic hepatitis B. Which instruction is most important to prevent transmission to household contacts?" (Answer focuses on not sharing razors/toothbrushes, safe sex practices, covering open wounds).
Shift to "Post-Exposure" Scenario: "A nurse sustains a needlestick injury from a patient with unknown hepatitis B status. What is the nurse's immediate action?" (Answer: Wash the site with soap and water, then follow facility protocol for exposure reporting and baseline blood testing).
Comparing Hepatitis Types: A question may list symptoms (e.g., jaundice, dark urine) and ask which type of viral hepatitis is transmitted via the fecal-oral route (Hepatitis A).
Nursing Clinical Practice GuideClinical Scenario: You are assigned to Mr. Johnson, a 60-year-old with chronic hepatitis B admitted for abdominal pain. He has an IV line, and you need to draw blood for labs.
Nursing Intervention Strategy:
Assessment: Assess for any active bleeding, open wounds, or uncontrolled secretions. Check the integrity of his IV site.
Planning & Implementation: Before entering the room, plan your tasks. Gather all supplies (gloves, lab tubes, sharps container). Perform hand hygiene. Don gloves before any potential contact with blood (e.g., accessing his IV line or drawing blood). After the procedure, dispose of the needle immediately in a puncture-resistant sharps container at the point of use. Remove gloves, perform hand hygiene. Label the blood tubes appropriately. Clean any surfaces if contamination occurred.
Patient Education: Educate Mr. Johnson about his condition. Explain why you are wearing gloves—to protect both of you. Teach him to cover any cuts or sores and to inform household members not to share personal items like razors or toothbrushes.
Evaluation: Ensure no exposure incidents occurred. Confirm that all contaminated materials were disposed of correctly.
Patient Safety and Precautions:
Sharps Safety is Paramount: Never recap used needles. Use safety-engineered devices if available.
PPE Selection: Gloves are mandatory for contact with blood or body fluids. Add a gown if soiling of clothing is likely (e.g., assisting with incontinence care). A mask and eye protection are needed only if splashing is anticipated (not for routine blood draw).
Environmental Cleaning: Standard hospital disinfectants are effective against HBV. Focus on frequent hand-touch surfaces.
Nursing Procedure & Medication FlowProcedure: Safe Blood Draw from a Patient with a Bloodborne Pathogen
1. Perform hand hygiene.
2. Don clean gloves.
3. Prepare equipment on a clean surface.
4. Perform venipuncture using a safety-engineered needle/device.
5. Key Point! Activate the safety feature immediately after withdrawing the needle from the patient's vein.
6. Dispose of the entire blood collection unit (needle and holder) directly into the sharps container.
7. Remove gloves and perform hand hygiene.
8. Label tubes outside the patient's room.
A Word from Your Senior Nurse
"In the real world, you won't always have a big sign on the door telling you what precautions to use. That's why Standard Precautions are non-negotiable for every patient, every time. Treat every drop of blood, every body fluid as potentially infectious. This habit protects you from unknown infections and protects your patients from cross-transmission. When you see 'hepatitis B' on the chart, don't panic and jump to isolation—instead, double down on the basics: meticulous hand hygiene and flawless sharps handling. That's the mark of a safe, professional nurse."
