A nurse is preparing to care for a 60-year-old patient who has consented to corneal donation after death. Which action by the nurse demonstrates proper understanding of eye tissue donation protocols?

해설
Proper eye tissue donation requires keeping the patient's head elevated and eyes closed with moist gauze pads after death to maintain tissue viability. Other options involve incorrect timing, inappropriate cooling, or potential damage.

Core Nursing Explanation Key Concept Analysis: This question tests the nurse's knowledge of the specific post-mortem care protocols for corneal donation. The goal is to preserve the viability of the corneal tissue for transplantation, which requires maintaining a moist environment and preventing physical damage or contamination. The key principle is that the cornea must remain viable for several hours after circulatory death, and nursing actions directly impact this viability.

Answer Rationale: Key Point! Option ④ is correct because it follows the standard protocol for eye care after death for donation. Elevating the head (at least 30 degrees) helps reduce edema and venous congestion in the orbital area, which can compromise tissue quality. Closing the eyes and applying moist gauze pads (often soaked in sterile saline) prevents the corneas from drying out (desiccation), which is the primary threat to tissue viability. This action maintains a humid microenvironment.

Distractor Analysis:
Watch out for confusion! Option ① is incorrect. While cooling the body is often part of post-mortem care, placing ice packs directly on the eyes can cause frostbite and freeze the delicate corneal tissue, rendering it non-viable for transplant. If cooling is required, it should be applied to the general body/head area, not directly on the eyes.
Option ② is incorrect. Timing is critical. The eye bank must be notified immediately after death (or as per specific protocol, often within a few hours) to begin the retrieval process. An 8-12 hour delay would almost certainly result in tissue degradation and make donation impossible. Family grieving is important but does not override the time-sensitive nature of tissue procurement.
Option ③ is incorrect. While contact lenses should be removed, irrigating the eyes with saline is not a standard step and could introduce contaminants or cause mechanical damage. The proper action is gentle closure and application of moist gauze, not irrigation.

Related Concepts: This protocol is part of a broader set of tissue and organ donation guidelines. Nurses must understand the differences in post-mortem care for corneal donation versus solid organ donation (which may require maintaining the patient on mechanical ventilation until organ retrieval). The nurse's role includes honoring the patient's wishes (confirmed consent), providing sensitive care to the family, and executing precise clinical steps to preserve the gift of donation.

Concept Summary
ConceptKey Nursing ActionRationale
Corneal ViabilityPrevent drying (desiccation)Corneas must remain moist to be transplantable.
Post-Mortem Head PositionElevate head of bed 30°Reduces orbital edema and venous pressure.
Eye CareClose lids, apply moist saline gauzeCreates a humid chamber; protects from physical damage.
NotificationContact eye bank immediately after deathProcurement is time-sensitive (usually within 6-12 hrs).
Contraindicated ActionsNo direct ice, no irrigation, no delayPrevents tissue freezing, contamination, and degradation.

AspectCorneal / Tissue DonationSolid Organ Donation (e.g., Heart, Kidney)
Time SensitivityModerate (Several hours post-mortem)Very High (Minutes to hours; requires maintained circulation)
Post-Mortem PhysiologyCirculatory death has occurred.Patient is often brain dead but maintained on mechanical ventilation to perfuse organs.
Key Nursing PreparationLocal care to eyes (moisture, elevation).Systemic care: maintaining hemodynamics, ventilation, and normothermia.
Consent FocusOften based on patient's prior directive (donor registry) or next-of-kin consent after death.Requires extensive coordination and consent prior to withdrawal of life support.

Anatomy, Physiology & Pharmacology PointsCornea: The transparent front part of the eye that covers the iris and pupil. It is avascular (has no blood vessels) and receives oxygen and nutrients from the tear film and aqueous humor. This is why it can remain viable for a period after circulatory death. • Desiccation: The process of drying out. Corneal epithelial cells are highly susceptible to desiccation, which leads to cell death and makes the tissue opaque and unsuitable for transplantation. • No specific pharmacology is involved in post-mortem corneal care, but maintaining a sterile/clean technique is paramount to prevent bacterial contamination.
Memory TipsM.O.I.S.T.: A mnemonic for post-mortem corneal care:
Moist gauze on eyes.
Obtain consent verification.
Immediate notification (eye bank).
Slightly elevate head.
Time is critical (no delay). • Think: "Eyes need to cry even after death." They need moisture (saline) to stay viable.
High-Frequency NCLEX Topics NCLEX often tests the nurse's knowledge of client rights and advocacy, including honoring advance directives and donation wishes. Questions on specific, time-sensitive procedures (like this one) assess your ability to apply protocol knowledge accurately. Remember: Key Point! Immediate action and preventing tissue damage are almost always the priority in donation scenarios.
Watch Out for Question Variations! • Instead of asking for the correct action, a question might ask: "Which action by the nurse requires immediate intervention/correction by the charge nurse?" The incorrect options from this question would be the answer. • A question could integrate this into a nursing priority scenario: "After the death of a client who is a corneal donor, which action should the nurse take first?" The answer would be to notify the eye bank immediately or initiate eye care (close lids, moisten), depending on how the choices are framed.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: Mr. Johnson, 60, admitted with terminal pancreatic cancer, has a "Donor" designation on his driver's license and his family confirms his wish for corneal donation. He passes away peacefully at 2:00 AM. As the primary nurse, you are responsible for the initial post-mortem care to facilitate donation.

Nursing Intervention Strategy: 1. Assessment & Verification: Confirm the patient's identity, time of death, and documented consent for donation (check chart, donor registry, or next-of-kin authorization). Perform a quick visual assessment of the eyes for any obvious injury or infection that might contraindicate donation (though the eye bank makes final determination). 2. Immediate Actions (First 5-10 minutes): • Gently close the patient's eyelids. • Elevate the head of the bed to at least 30 degrees. • Apply sterile gauze pads lightly moistened with sterile normal saline over the closed eyelids. Do not soak them; they should be damp, not dripping. • Simultaneously, or immediately after, notify the charge nurse and/or follow facility protocol to contact the designated eye bank or organ procurement organization (OPO). The clock starts at the time of death. 3. Ongoing Care & Documentation: • Maintain head elevation and moisture to the eyes until the eye bank team arrives. • Document meticulously: time of death, time of notification to eye bank, actions taken for eye care, and any communications with the family or donation coordinator. • Provide compassionate, private space for the family to grieve, explaining the steps you are taking to honor their loved one's wishes.

Patient Safety and Precautions: • Key Point! Never use tape on the eyelids, as it can damage the skin and lashes. • Avoid contamination: Use sterile saline and gauze. Wash hands and wear gloves. • No pressure: Do not place any significant weight or pressure on the eyes. • Communication: Coordinate with the mortuary or funeral home staff upon their arrival to inform them the patient is a corneal donor, so they continue appropriate care.
Nursing Procedure & Medication Flow This is a non-medication procedure. The "flow" is a sequence of time-critical tasks: Step 1: Verify death and consent. → Step 2: Perform eye care (close lids, elevate HOB, apply moist gauze). → Step 3: Notify eye bank/OPO (per facility policy). → Step 4: Continue care (maintain moisture, position) until procurement team arrives. → Step 5: Complete documentation and provide family support.
A Word from Your Senior Nurse "Honoring a patient's final wish to be a donor is a profound and sacred nursing responsibility. It turns a moment of loss into a legacy of gift. In the quiet of the night after a death, it's easy to feel rushed or unsure. Remember your protocol: Moisture, Elevation, Notification. Doing these simple steps correctly can literally give someone else the gift of sight. On the NCLEX, they test this because it's a clear, protocol-driven intervention where your knowledge has a direct, tangible impact. In real life, it's one of the most meaningful procedures you'll ever perform."
