Core Nursing Explanation
Key Concept Analysis: This question assesses the
priority nursing intervention for a potential kidney transplant rejection. The patient is 6 months post-transplant and presents with classic signs of graft dysfunction: fatigue, decreased urine output, abdominal pain (over the graft site), and elevated serum creatinine and BUN. These lab values (
Creatinine 2.8 mg/dL,
BUN 45 mg/dL) indicate a decline in kidney function. In the context of transplantation, the most critical and time-sensitive concern is
acute rejection, which requires immediate medical evaluation to salvage the transplanted organ.
Answer Rationale:
Key Point! The priority is to
notify the transplant team immediately. This team is specialized in managing transplant recipients. A prompt response allows for rapid assessment, which often includes a
renal biopsy to confirm rejection and guide treatment (e.g., intensifying immunosuppressive therapy). Delaying this notification could lead to irreversible damage to the transplanted kidney.
Distractor Analysis:
•
Watch out for confusion! Option ①: Increasing fluid intake could be harmful. The patient's decreased urine output may be due to rejection, not dehydration. Forcing fluids could lead to fluid overload, especially if the kidney is not functioning properly.
• Option ②: Administering diuretics is not the priority and could be dangerous. Diuretics do not treat the underlying cause (rejection) and could worsen electrolyte imbalances or renal perfusion if the issue is vascular compromise.
• Option ④: While ambulation and deep breathing are generally good for post-operative patients, they do not address the acute, potentially life-threatening problem of organ rejection. This is a supportive measure, not a priority intervention.
Related Concepts: Key signs of transplant rejection include: graft tenderness/pain, fever, malaise, and a sudden rise in serum creatinine. Immunosuppressant therapy (e.g., tacrolimus, cyclosporine, mycophenolate) is lifelong to prevent rejection, but requires careful monitoring for side effects like infection, nephrotoxicity, and hypertension.
Concept Summary
•
Priority Action: Suspected rejection → Immediate notification of transplant team.
•
Key Assessment Findings: Decreased urine output, elevated creatinine/BUN, graft site pain, fatigue.
•
Definitive Diagnosis: Often requires tissue biopsy.
•
Nursing Role: Vigilant monitoring, patient education on medication adherence and signs of rejection/infection.
Side-by-Side Comparison!
| Condition | Key Features | Nursing Priority |
|---|
| Acute Transplant Rejection | Graft dysfunction (↑Cr/BUN, ↓UO), graft pain, fever. Occurs days to months post-transplant. | Immediate notification of specialist team for evaluation and rescue therapy. |
| Chronic Transplant Rejection | Slow, progressive decline in function over years. Often irreversible. | Long-term management of comorbidities (HTN, DM), medication adherence, routine monitoring. |
| Immunosuppressant Toxicity (e.g., Cyclosporine) | Can also cause ↑Cr/BUN (nephrotoxicity), but often without graft pain. May have tremors, gum hyperplasia. | Monitor drug levels, assess for other side effects, collaborate on dose adjustment. |
Anatomy, Physiology & Pharmacology Points
•
Creatinine & BUN: Waste products cleared by the kidneys. Rising levels are a direct marker of
decreased glomerular filtration rate (GFR).
•
Rejection Pathophysiology: The recipient's immune system (T-cells and antibodies) recognizes the transplanted kidney as "foreign" and attacks it.
•
Immunosuppressants: Drugs like
tacrolimus and
mycophenolate mofetil suppress T-cell activation and proliferation to prevent this immune attack.
Memory Tips

Acronym for Rejection Signs:
Fever,
Flu-like symptoms,
Fatigue,
Function decline (↑Cr),
Firm/tender graft.
•
Priority Rule: In transplant nursing, any sign of potential rejection =
ACT FAST. Notify the expert team first.
High-Frequency NCLEX Topics
NCLEX frequently tests
priority-setting and recognizing complications. Transplant rejection is a classic "priority" scenario. The exam wants you to identify the most urgent action that requires specialized intervention, not just routine supportive care.
Watch Out for Question Variations!
• Instead of asking for the intervention, a question might ask:
"The nurse identifies which finding as most concerning in a kidney transplant recipient?" (Answer: A sudden increase in serum creatinine).
• The scenario could shift to
signs of infection (fever, cough) in an immunosuppressed patient, testing your knowledge of the
balance between rejection risk and infection risk.
