A nurse is preparing to enter the isolation unit for a patient with suspected Ebola virus disease. Which personal protective equipment (PPE) sequence demonstrates the correct donning procedure for enhanced contact precautions?

The correct donning sequence (hand hygiene → gown → mask/respirator → eye protection → gloves → boot covers → hand hygiene) follows CDC/WHO guidelines to build multiple protective barriers. Other options disrupt this systematic approach, increasing contamination risk.

Core Nursing Explanation Key Concept Analysis: This question tests the critical skill of donning Personal Protective Equipment (PPE) for a patient under enhanced contact precautions for a highly contagious and dangerous pathogen like Ebola virus disease (EVD). The core principle is to create a protective barrier in a specific sequence that minimizes the risk of contaminating yourself or the environment. For high-consequence pathogens, the sequence is designed to protect the most critical areas (respiratory tract, mucous membranes) and ensure the final step (gloving) seals the gown cuffs, preventing any skin exposure.

Answer Rationale: Key Point! The correct sequence in option ① follows the CDC/WHO-recommended "clean to dirty" and "most critical protection last" logic. Hand hygiene is always first. The gown is donned next to cover the torso and arms, establishing a large clean surface. The mask/respirator and eye protection are then applied to protect the mucous membranes of the face before gloves. This order is crucial because adjusting a mask or goggles with contaminated gloves would pose a direct infection risk. Gloves are donned last to pull them over the gown cuffs, creating a sealed barrier. A final hand hygiene step after donning all PPE ensures hands are clean before patient contact, even though they will be gloved.

Distractor Analysis:
Watch out for confusion! Option ② puts the gown on before hand hygiene. This is incorrect because your hands are not clean before touching the clean inside of the gown, potentially contaminating it.
Option ③ puts the mask/respirator on before the gown. While this protects the airway early, it risks contaminating the outside of the mask when pulling the gown over the head, which could later lead to self-contamination when doffing (removing).
Option ④ puts eye protection on immediately after hand hygiene. This is illogical and unsafe, as eye protection can be easily dislodged when putting on a gown or mask over the head, and it does not follow the systematic build-up of barriers.

Related Concepts: The Doffing (removal) sequence is equally, if not more, critical and is performed in reverse order (gloves, eye protection, gown, mask/respirator) with meticulous hand hygiene between steps to prevent self-contamination. The principles of Standard Precautions and Transmission-Based Precautions (Contact, Droplet, Airborne) form the foundation, with enhanced precautions adding more layers of PPE for specific high-risk pathogens. Concept Summary

Concept	Description	Application
Enhanced Contact Precautions	Used for pathogens spread by direct/indirect contact that pose a high risk of severe illness (e.g., Ebola, C. difficile, MDROs). Involves gown and gloves, plus face/eye protection if splashes are possible.	Ebola Virus Disease requires full PPE: impermeable gown, respirator (N95 or PAPR), face shield/goggles, double gloves, boot covers.
PPE Donning Principle	"Clean to Dirty": Start with hand hygiene. Protect torso, then airway/eyes, then seal with gloves. Goal is to avoid contaminating clean PPE during donning.	Sequence: 1. Hand Hygiene 2. Gown 3. Mask/Respirator 4. Eye Protection 5. Gloves 6. (Boot Covers) 7. Final Hand Hygiene.
PPE Doffing Principle	"Dirty to Clean": Remove most contaminated items first in a controlled manner to prevent self-inoculation. Assume outside of all PPE is contaminated.	Sequence: 1. Gloves 2. Hand Hygiene 3. Eye Protection 4. Gown 5. Hand Hygiene 6. Mask/Respirator 7. Final Hand Hygiene.

Airborne Precautions	Fit-tested N95 Respirator or PAPR. Gown/gloves as needed.	Respirator must be donned before entering and sealed-checked. Hand hygiene first.	Measles, Tuberculosis (TB), Varicella.
Enhanced Precautions (Ebola)	Full ensemble: Impermeable gown, N95/PAPR, face shield, double gloves, boot/leg covers.	Strict, multi-step sequence with a trained observer. Final seal check is critical.	Ebola Virus Disease, Marburg, other VHFs.

Anatomy, Physiology & Pharmacology Points • Pathophysiology: Ebola virus is transmitted via direct contact with blood or body fluids (including sweat) of an infected person or contaminated surfaces/objects. The virus enters through broken skin or mucous membranes (eyes, nose, mouth). This is why Key Point! complete skin and mucous membrane coverage with impermeable barriers is non-negotiable. • No Specific Drug: There is no widely available curative antiviral for Ebola. Supportive care (fluid resuscitation, electrolyte management) is mainstay, making impeccable infection prevention the primary defense for healthcare workers. Memory Tips • Donning Mnemonic: "Hugs Make Great Eye Glasses" (Hand hygiene, gown, Mask/respirator, eye protection, Gloves). Add "Boots" and final "Hugs" (hand hygiene) at the end. • Doffing Mnemonic: "Gloves Come Off, Eyes Go, Gown Goes, Mask Goes" (Gloves, [Hand hygiene], eye protection, Gown, [Hand hygiene], Mask, [Final hand hygiene]). Remember hand hygiene between key steps! • Think: "Protect your core, then your face, then seal it all in place." High-Frequency NCLEX Topics PPE and infection control are High Yield topics. The NCLEX-RN loves to test: 1. Sequence: Donning and doffing order for various precautions. 2. Priority: What action to take first when entering/exiting an isolation room. 3. Rationale: Understanding *why* a sequence is followed (to prevent contamination). 4. Specific Diseases: Matching the correct type and level of PPE to a given pathogen (e.g., TB = N95, C. diff = soap and water hand hygiene). Watch Out for Question Variations! • Instead of asking for the sequence, a question might show a picture of a nurse in incomplete PPE and ask, "Which additional item is required?" (e.g., missing goggles for a contact precaution patient with diarrhea). • A scenario might describe a breach in technique (e.g., "The nurse adjusts her goggles with a gloved hand") and ask for the appropriate corrective action or the associated risk. • Questions may test the difference between alcohol-based hand rub (for most situations) and soap and water (required for C. difficile, norovirus, or when hands are visibly soiled).

Nursing Clinical Practice Guide Clinical Scenario: You are assigned to a specialized isolation unit. Your patient, Mr. Jones, was admitted 24 hours ago with fever, severe headache, and vomiting after recent travel from a region with active Ebola transmission. Lab tests are pending, but he is placed under enhanced contact precautions.

Nursing Intervention Strategy: 1. Assessment & Planning: Before entering, review the patient's status from outside the room. Gather all necessary supplies (medications, linens, lab tubes) to minimize entries/exits. Ensure a trained "PPE observer" is present. 2. Implementation - Donning: • Perform Hand Hygiene with alcohol-based rub at the anteroom station. • Inspect all PPE for defects. Don the impermeable gown, tying securely at neck and waist. • Don the N95 respirator, perform a seal check. If using a PAPR, turn it on. • Put on face shield or goggles. • Don inner gloves, pulling them over the gown cuffs. Don outer gloves (double-gloving). • Put on boot or leg covers. • Perform final hand hygiene on gloved hands (yes, this is done!). • The observer verifies the integrity of your ensemble before you enter. 3. Patient Care: Provide care efficiently. Limit touching surfaces. All waste inside the room is considered biohazardous. 4. Implementation - Doffing (MOST CRITICAL PHASE): • Remove in the dedicated doffing area with observer guidance. • Key Point! Perform slow, deliberate movements. The observer talks you through each step to prevent error.

Patient Safety and Precautions: • Contraindication: Never enter the isolation room without a complete, properly donned PPE ensemble. No exposed skin or hair. • Key Monitoring: Monitor yourself for any breach (tear in glove, gown saturation). If a breach occurs, exit immediately and follow exposure protocol. • Visitor Policy: No unauthorized visitors. Family education is provided remotely. Nursing Procedure & Medication Flow PPE Doffing Procedure (Step-by-Step with Observer): 1. Disinfect outer gloves with approved disinfectant wipe. 2. Remove boot/leg covers by grasping and pulling from the inside. 3. Remove outer gloves using the "glove-in-glove" technique, turning them inside out. 4. Hand Hygiene on inner gloves. 5. Remove face shield/goggles by handling the headband only. Discard. 6. Remove gown by unfastening ties, peeling away from neck and shoulders, turning inside out, and rolling into a bundle. Discard. 7. Hand Hygiene on inner gloves. 8. Remove inner gloves using proper technique. 9. Perform Hand Hygiene on bare hands. 10. Remove mask/respirator by touching only the straps (N95) or removing PAPR hood. Discard. 11. Perform Final Hand Hygiene.
Medication Administration: Prepare IV medications outside the room if possible. Enter with pre-drawn syringes. Use IV pumps with external controls if available. Disinfect all equipment (e.g., pump) upon removal. A Word from Your Senior Nurse "Infection control, especially with high-consequence pathogens, is where textbook knowledge meets life-or-death practice. The sequence isn't just a list to memorize for the NCLEX; it's a ritual that protects you, your colleagues, your other patients, and your family. In the heat of a clinical moment, it's easy to want to rush in to help. But remember: you are no help to anyone if you become a patient yourself. Practice these sequences mentally until they become muscle memory. On the NCLEX, when you see an infection control question, pause and hear the voice of your safety officer: 'Slow is smooth, and smooth is fast.' Get the sequence right, understand the 'why,' and you'll ace those questions while building an unshakable foundation for safe practice."
