Other options are not the highest priority interventions. ## 심화 해설 Understanding the Priority Intervention for Hepatitis B Prevention The correct answer is 4. Implementing standard precautions with emphasis on safe handling of blood and body fluids. The primary mode of transmission for the hepatitis B virus (HBV) in healthcare settings is through percutaneous or mucosal exposure to infected blood and certain body fluids. This makes rigorous adherence to standard precautions the single most critical strategy for protecting both healthcare workers and other patients. Why Standard Precautions Are the Priority HBV is a bloodborne pathogen with a high viral load in the blood of an acutely infected individual. The virus can survive on environmental surfaces for at least seven days and remains capable of causing infection. Standard precautions, as defined by the CDC, are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin, and mucous membranes. For a patient with acute hepatitis B, the key elements of standard precautions include: - Meticulous hand hygiene before and after patient contact. - Consistent use of gloves when handling blood, body fluids, or items contaminated with them. - Safe injection practices, including the use of safety-engineered devices to prevent needlestick injuries. - Proper disposal of sharps in puncture-resistant containers. - Use of appropriate personal protective equipment (PPE), such as gowns and face protection, when splashes or sprays of blood or body fluids are anticipated. Analysis of Incorrect Options 1. Administering hepatitis B immune globulin to the patient is not a primary prevention strategy for healthcare workers. Hepatitis B immune globulin (HBIG) provides passive immunity and is administered as post-exposure prophylaxis to a susceptible, unvaccinated person who has had a documented exposure to HBV. It is not a treatment given to the source patient to reduce their infectivity or to protect staff. 2. Placing the patient in airborne precautions isolation is incorrect because HBV is not transmitted via the airborne route. Airborne precautions are reserved for pathogens that can be transmitted through small droplet nuclei that remain suspended in the air, such as tuberculosis, measles, and varicella. Hepatitis B is a bloodborne pathogen requiring standard precautions. 3. Restricting all visitors from entering the patient's room is an unnecessary and overly restrictive measure. Visitors do not require restriction based solely on a hepatitis B diagnosis. They should be educated on the importance of standard precautions, particularly hand hygiene, and should not come into direct contact with the patient’s blood or body fluids. Complete restriction is not indicated and can negatively impact the patient’s psychosocial well-being. Clinical Application and Pathophysiology The pathophysiology of HBV involves a double-stranded DNA virus that targets hepatocytes, leading to liver inflammation and necrosis. During the acute phase, viremia is high, making the patient’s blood and serous fluids extremely infectious. The virus is structurally resilient, contributing to its stability outside the host and reinforcing the need for environmental cleaning and disinfection as a component of standard precautions. The global burden of acute hepatitis B, as highlighted in systematic analyses, underscores its significant public health impact and the continuous risk of transmission in healthcare environments where blood and body fluid exposure can occur. Therefore, the consistent and correct implementation of standard precautions is the foundational and most effective nursing intervention to break the chain of infection at the point of care. ## 임상 시나리오 Clinical Practice Guide: Preventing Hepatitis B Transmission For a patient with acute hepatitis B, the priority nursing action is implementing standard precautions with strict adherence to safe handling of blood and body fluids. Hepatitis B virus (HBV) is a highly infectious bloodborne pathogen that can survive on environmental surfaces for at least seven days. **Key Infection Control Measures:** - Perform meticulous hand hygiene before and after every patient contact, even if gloves are worn. - Wear gloves consistently when anticipating contact with blood, body fluids, mucous membranes, or contaminated items. - Utilize safety-engineered sharps devices and dispose of all needles and sharps immediately in puncture-resistant containers without recapping. - Apply additional personal protective equipment such as gowns, masks, and eye protection when splashes or sprays of blood or body fluids are expected. - Clean and disinfect environmental surfaces and reusable equipment with an EPA-registered disinfectant effective against HBV. **Clinical Reasoning:** Unlike airborne pathogens, HBV does not require airborne isolation. Administering hepatitis B immune globulin is a post-exposure intervention for the exposed person, not a transmission prevention strategy for the source patient. Visitor restriction is not indicated; instead, educate visitors on proper hand hygiene and the use of barriers if they will have direct contact with the patient's blood or body fluids. ## 핵심 개념 - **Standard Precautions** — CDC-defined infection control practices used for all patients to prevent transmission of pathogens via blood, body fluids, non-intact skin, and mucous membranes. - **Hepatitis B Virus (HBV)** — A highly infectious bloodborne virus that causes liver inflammation and can survive on surfaces for at least seven days. - **Bloodborne Pathogen** — Infectious microorganisms in human blood that can cause disease, transmitted primarily through percutaneous or mucosal exposure. - **Post-Exposure Prophylaxis (PEP)** — Preventive medical treatment started immediately after exposure to a pathogen to prevent infection, such as HBV immune globulin and vaccination. ## 같은 주제 문제 - [A nurse is assessing a 28-year-old patient who recently returned from a developing country…](https://mymerci.kr/pages/nclex_q.php?qn_id=541855) - [A nurse is assessing a 28-year-old patient who presents with jaundice, dark urine, and cla…](https://mymerci.kr/pages/nclex_q.php?qn_id=541856) - [A nurse is assessing a 35-year-old patient who recently returned from international travel…](https://mymerci.kr/pages/nclex_q.php?qn_id=541857) - [A nurse is caring for a patient diagnosed with acute hepatitis B.
