Which action demonstrates the highest priority safety measure when handling antineoplastic medications? ## 보기 1. Double-gloving with chemotherapy-approved gloves and wearing a disposable gown with closed front and cuffed sleeves **✔ 정답** 2. Verifying the patient's identity using two identifiers before medication administration 3. Checking the patient's complete blood count results from the morning laboratory draw 4. Ensuring the patient has signed informed consent for chemotherapy treatment **정답: 1** ## 해설 Personal protective equipment (PPE) like double-gloving and wearing a disposable gown is the highest priority safety measure when handling antineoplastic medications to prevent occupational exposure and contamination. Other actions like patient verification, CBC checks, and consent are important but do not address immediate staff safety risks. ## 심화 해설 Understanding the Priority: Hierarchy of Safety in Chemotherapy Administration When administering antineoplastic medications, the nurse must prioritize actions using a safety hierarchy. While patient identification, laboratory verification, and informed consent are critical for patient safety, the immediate physical protection of the healthcare provider from hazardous drug exposure represents the highest priority action during the physical act of handling and administering the drug. This is because occupational exposure to chemotherapy agents carries carcinogenic, mutagenic, and teratogenic risks that are immediate and cumulative, as highlighted by research on cytotoxic drug handling practices [4]. The correct action is the one that creates a primary engineering and work-practice control barrier between the nurse and the drug. Analysis of the Correct Answer: Option 1 The use of double-gloving with chemotherapy-approved gloves and a disposable gown with a closed front and cuffed sleeves is the highest priority safety measure during the handling phase. This is not merely a routine precaution; it is a direct application of the hierarchy of controls to mitigate occupational exposure. A qualitative descriptive study identified that a nurse's personal health belief and the description of exposure incidents are central themes influencing safety practices . The physical barrier of Personal Protective Equipment (PPE) is the most immediate defense against accidental splashes, spills, or aerosolization during preparation and administration. Research into factors influencing compliance with standard operating procedures underscores that consistent use of proper PPE is a fundamental behavioral factor in preventing direct contact with hazardous substances . Without this barrier in place first, the nurse is immediately vulnerable to the drug's toxic effects, making this the foundational safety step. Why Other Options Are Lower Priority - Option 2 (Verifying patient identity): This is a non-negotiable patient safety step that prevents medication errors. However, it occurs before the physical handling of the chemotherapy agent. Once the drug is in hand for administration, the immediate risk shifts to the nurse. A cross-sectional study on nurses' knowledge and safe-handling practices emphasizes that knowledge of controls does not always translate to practice, and the physical act of handling is where exposure risk is actualized . Patient identification is a prerequisite, not the concurrent priority during hazardous drug manipulation. - Option 3 (Checking complete blood count results): This is a critical assessment step to determine if it is safe for the patient to receive myelosuppressive chemotherapy. While essential, this action is an assessment of patient readiness and does not protect the nurse from the inherent toxicity of the drug during administration. The qualitative findings on chemotherapy safety highlight that exposure incidents are often related to the handling process itself, not the patient's lab values . This step is secondary to establishing a safe handling environment for the clinician. - Option 4 (Ensuring signed informed consent): This is a legal and ethical prerequisite for treatment initiation. It confirms the patient's understanding and agreement to proceed. However, like patient identification, this verification is completed before the drug is brought to the bedside for administration. The presence of a signed consent form does not mitigate the physical risk of dermal absorption or inhalation of the hazardous drug during the moment of administration. Studies on compliance factors show that administrative steps like consent, while mandatory, are distinct from the behavioral and physical safety practices required during cytotoxic drug handling [3, 4]. Integrating Evidence into Clinical Judgment The clinical reasoning for this NCLEX-RN question requires the nurse to distinguish between patient-directed safety measures and self-protective occupational safety measures at the exact point of drug administration. The evidence consistently points to a gap between knowledge and actual safe-handling practices, often due to personal beliefs or perceived obstacles [1, 2]. The nurse must internalize that self-protection is not optional but a core component of professional practice. The physical act of donning appropriate PPE, specifically double-gloving and a fluid-resistant gown, is the terminal and most critical step in a sequence that begins with verification and assessment. This action directly prevents the exposure incidents described by oncology nurses, such as skin contact during connection or disconnection of tubing . Therefore, when the question asks for the highest priority measure when handling the medication, the action that creates a physical barrier between the nurse and the hazardous drug takes precedence over all preceding verification steps.References (research sources) - [4]Cytotoxic Drug Handling Practices Among Pharmacy Technicians in Portugal: The Dig Deeper Study.Research articleReis A, Silva V, Joaquim JJ, Matos C, Valeiro C, Freitas C, Pereira OR, Mateos-Campos R, Moreira F. (2026) · DOI: 10.3390/healthcare14070963 ## 임상 시나리오 Safe Handling of Antineoplastic DrugsDonning PPE as the Primary Exposure Control The highest priority during chemotherapy administration is creating a physical barrier between the nurse and the drug. This is achieved by donning Personal Protective Equipment (PPE), specifically double-gloving with chemotherapy-approved gloves and wearing a disposable, closed-front gown with cuffed sleeves. This practice directly applies the hierarchy of controls. PPE serves as the most immediate defense against occupational exposure to agents with carcinogenic, mutagenic, and teratogenic risks. Standard gloves and gowns are insufficient; only designated, tested materials provide adequate protection. CautionPatient verification, lab checks, and consent are critical but are administrative controls. They do not protect the nurse from direct contact, splashes, or aerosolization during drug handling. The physical act of donning PPE must precede these steps when preparing the medication. ## 핵심 개념 - **Antineoplastic** — Medications used to treat cancer by inhibiting the growth and spread of neoplastic cells; many are hazardous and require special handling. - **Hierarchy of Controls** — A system used in safety management to prioritize interventions, ranking elimination and physical barriers (PPE) above administrative controls like verification. - **Chemotherapy-approved gloves** — Gloves tested for permeability with specific chemotherapy drugs, often made of nitrile or latex, and used in double layers for enhanced protection. ## 같은 주제 문제 - [A nurse is caring for a patient receiving chemotherapy with vincristine.
