해설
Closing eyelids and placing moist gauze prevents corneal drying, which is critical for tissue viability. Other actions are important but secondary to immediate tissue preservation.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing action for preserving corneal tissue for transplantation from a brain-dead patient. The core principle is that corneal viability depends on preventing desiccation (drying) and maintaining a moist environment. Once circulation ceases, the avascular cornea quickly loses moisture, leading to cell death and making the tissue unsuitable for transplant. The immediate physical protection of the corneas is the most time-sensitive intervention.
Answer Rationale: Key Point! The correct answer is to close the patient's eyelids and place moist gauze pads over the eyes. This action directly addresses the primary threat to tissue viability—drying. It is a simple, immediate, and independent nursing intervention that can be performed without an order and does not require waiting for other personnel or procedures. It is the foundational step in the preservation process.
Distractor Analysis:
Watch out for confusion! While administering prescribed eye drops (Option 2) is a standard part of corneal preservation protocols, it is typically done after the initial physical protection. The drops (often antibiotic or lubricating) require a physician's order and are not the first action the nurse should take upon identifying the need for preservation.
Watch out for confusion!Documenting the time of death (Option 3) is a crucial legal and administrative responsibility. However, it does not contribute to the immediate physiological goal of preserving tissue. This can be done concurrently or immediately after the priority action.
Watch out for confusion!Contacting the organ procurement organization (OPO) (Option 4) is an essential and urgent step in the donation process. However, the OPO coordinator will provide specific instructions for preservation, which will include measures like eye drops and possibly cooling. The nurse's first action upon recognizing the potential for donation—before that call is made—should be to initiate basic preservation to "buy time" and protect the tissue.
Related Concepts: This scenario integrates concepts of end-of-life care, ethical/legal aspects of organ donation (Uniform Anatomical Gift Act), and the specific physiological requirements of different transplantable tissues. Understanding that different organs (heart, liver, kidneys) and tissues (corneas, skin, bone) have vastly different preservation requirements and timeframes is key.
Concept Summary
Concept
Key Points
Brain Death
Irreversible cessation of all brain function, including the brainstem. Legal definition of death. Patient is a potential organ/tissue donor while cardiopulmonary function is maintained.
Corneal Tissue Viability
Corneas are avascular. Primary threat is desiccation (drying). Must be kept moist and protected from physical damage. Viability window is longer than for vascular organs (can be several hours to a day post-mortem if preserved).
Nursing Priority in Tissue Donation
Immediate, independent actions to preserve tissue viability come first (e.g., moist gauze for eyes). Then follow institutional and OPO protocols (documentation, notification, administering specific solutions).
Organ Procurement Organization (OPO)
Federally designated organization that coordinates the donation process, evaluates donors, arranges for surgical recovery, and allocates organs/tissues.
Side-by-Side Comparison!
Action
Priority & Rationale
Timing
Close eyelids & apply moist gauze
FIRST PRIORITY. Independent nursing action. Directly prevents corneal drying, the most immediate threat.
Immediately upon identification of potential corneal donation.
Contact Organ Procurement Organization (OPO)
High priority but secondary. Necessary to formalize the process and get specific preservation instructions.
As soon as possible after initial tissue protection.
Administer prescribed eye drops
Important protocol step. Often contains antibiotics and/or solutions to maintain endothelial cell health.
After initial protection, per OPO or hospital protocol/physician order.
Document time of death
Mandatory legal requirement. Does not affect tissue viability.
Can be done concurrently or immediately after priority action.
Anatomy, Physiology & Pharmacology Points
Cornea Anatomy: The transparent, avascular front part of the eye. It relies on tear film and aqueous humor for oxygen and nutrients. Its endothelial cell layer is crucial for clarity and is very sensitive to damage from drying.
Preservation Pharmacology: Eye drops used may include topical antibiotics (e.g., gentamicin) to prevent infection, and solutions like hypothermic storage media (e.g., Optisol-GS) that provide nutrients and maintain cell function during storage and transport.
Memory Tips
Mnemonic: "M.E.D.S. First" for corneal care: Moisten, Eyelids closed, Don't let it Dry, Shield with gauze. Do this FIRST.
Think: "Dry eyes = Dead tissue." Your first job is to prevent dryness at all costs.
High-Frequency NCLEX Topics
The NCLEX frequently tests priority-setting in scenarios involving organ/tissue donation and end-of-life care. You must distinguish between a correct action and the first or priority action. The exam loves to present multiple correct nursing interventions and ask which one you do first. Always ask yourself: "What action, if delayed even by minutes, could cause harm or make another intervention impossible?"
Watch Out for Question Variations!
Instead of asking for the "first" action, the question might ask: "The nurse's priority is to..." or "Which action is most important for ensuring successful transplantation?"
The scenario could change the tissue: e.g., "The family consents to skin graft donation." The priority action would then shift to keeping the body cool or following specific OPO instructions for skin preservation, not eye care.
The question could test knowledge of who can give consent for donation (next-of-kin order) or the nurse's role in supporting the grieving family while also facilitating donation.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 45, with glioblastoma, has just been pronounced brain dead by two physicians following apnea testing. His advance directive and driver's license indicate he is a registered donor, and his wife at the bedside confirms she supports honoring his wishes for corneal donation.
Nursing Intervention Strategy:
Immediate Assessment & Action (First 2 minutes): After the time of death is declared, calmly explain to the family that you will take steps to honor the donation wish. Gently close the patient's eyelids. Apply sterile saline-moistened gauze pads over the closed eyes. You may place a protective eye shield over the gauze if available.
Notification & Coordination (Next 5-10 minutes): Inform the charge nurse and the attending physician. Contact the hospital's designated organ procurement organization (OPO) per policy. The OPO coordinator will guide the next steps.
Ongoing Care & Documentation: Administer any specific eye drops or solutions as ordered per OPO protocol. Continue to provide dignified post-mortem care to the body. Document thoroughly: time of death, declaration of brain death, family discussion regarding donation, notification of OPO, and all preservation measures taken.
Family Support: Provide emotional support, privacy, and answer questions. Reassure them that their loved one's wish is being respected and that donation does not disfigure the body for viewing.
Patient Safety and Precautions:
Use sterile technique when handling eyes and applying moist gauze to prevent introducing bacteria that could ruin the tissue.
Ensure the gauze is moist, not soaking wet, to avoid maceration of the surrounding skin.
Do not use tape directly on the eyelids. Tape the gauze or shield to the bony orbit (forehead and cheekbone).
Maintain patient dignity at all times. Explain your actions to the family to avoid alarming them.
Nursing Procedure & Medication FlowProcedure: Initial Corneal Preservation
1. Gather supplies: Sterile gloves, sterile gauze pads, sterile normal saline, eye shields (optional).
2. Don gloves.
3. Gently close both eyelids.
4. Moisten two gauze pads with sterile saline (wring out excess).
5. Place one moist pad over each closed eye.
6. If available, place a rigid eye shield over the gauze for physical protection.
7. Tape the shield/gauze in place laterally.
Medication (Post-OPO Contact): The OPO will often specify a regimen. A common order is for topical antibiotic drops (e.g., ofloxacin) every few hours. Administration:
- Wash hands, don gloves.
- Gently retract lower eyelid to form a pouch.
- Instill the prescribed number of drops into the pouch, avoiding contact of the dropper with the eye or lashes.
- Close the eyelid gently.
A Word from Your Senior Nurse
"In moments like these, nursing requires you to balance technical skill with profound compassion. You are caring for both the patient's legacy and the grieving family. That simple act of placing moist gauze isn't just a task—it's the bridge between a life lost and the gift of sight for someone else. On the NCLEX and in practice, remember: your first action is almost always the one that directly addresses the most immediate physiological threat. Think 'ABCs' for tissues: Keep them Alive (viable), keep them Bedded (protected), keep them Clean. You've got this!"
Brain Death — The irreversible cessation of all functions of the entire brain, including the brainstem. It is a legal definition of death and a prerequisite for organ donation from a heart-beating donor.
Cornea — The transparent, avascular front part of the eye that covers the iris and pupil. It is a commonly transplanted tissue, and its viability depends on preventing desiccation.
Organ Procurement Organization — A federally designated, non-profit organization responsible for evaluating potential donors, discussing donation with families, coordinating the surgical recovery of organs and tissues, and allocating them according to national policy.
Desiccation — The process of extreme drying. In the context of corneal donation, desiccation is the primary cause of tissue damage and loss of viability for transplantation.
Uniform Anatomical Gift Act — A model state law that has been adopted across the U.S. to govern the donation of organs, tissues, and other anatomical gifts. It establishes the legal framework for consent (first-person consent via donor registry) and the order of priority for next-of-kin decision-makers.
