Which of the following statements regarding the management of acute kidney rejection should the nurse include in client education? Select all that apply.

After a kidney transplant, the immune system may recognize the transplanted organ as foreign and initiate an inflammatory response known as acute rejection. This typically occurs within days to months post-transplant and can compromise graft function if not identified early. Clinical monitoring focuses on early signs of inflammation, reduced renal function, and systemic changes indicating immune activation. Prompt recognition is essential to preserve graft viability and prevent irreversible damage.

Rationale:
A. Fever and fluid retention are key indicators of potential acute rejection. Fever reflects an inflammatory or immune response against the transplanted kidney. Fluid retention occurs due to impaired renal function as the rejecting kidney loses its ability to regulate fluid balance effectively, often leading to edema and hypertension.

B. A steady increase in urine output is not typically associated with acute rejection and may instead indicate improving graft function or appropriate response to therapy. In acute rejection, urine output more commonly decreases due to declining renal function and reduced glomerular filtration.

C. Decreased blood creatinine levels suggest improved kidney function rather than rejection. In acute rejection, serum creatinine typically rises due to impaired filtration and declining graft performance. A downward trend in creatinine is a reassuring finding, not a warning sign.

D. Increased appetite and weight gain are not specific indicators of acute transplant rejection. While weight gain may occur due to fluid retention, increased appetite alone is not associated with immune-mediated graft dysfunction. More specific signs such as fever, rising creatinine, and reduced urine output are more clinically relevant.

Respiratory failure occurs when the respiratory system is unable to maintain adequate oxygenation and/or ventilation, leading to hypoxemia and possible organ dysfunction. Oxygen therapy is initiated to improve oxygen delivery to tissues and correct low oxygen levels. However, continuous monitoring is essential because worsening hypoxemia despite oxygen delivery indicates failure of therapy and potential deterioration. Early recognition of inadequate response is critical to prevent respiratory arrest and organ damage.

Rationale:
A. Decreasing oxygen saturation despite oxygen supplementation is the most concerning finding and requires immediate intervention. It indicates that oxygen therapy is not effectively correcting hypoxemia and that the client may be progressing toward severe respiratory failure. This may necessitate escalation of respiratory support, such as noninvasive ventilation or intubation, to prevent further deterioration.

B. A mild increase in respiratory rate is often a compensatory response to hypoxemia and may be expected in respiratory distress. While it should be monitored, it does not immediately indicate failure of oxygen therapy if oxygen saturation is improving or stable. It becomes more concerning only if it progresses or is associated with worsening oxygenation.

C. A slight increase in heart rate from baseline is also a common compensatory mechanism in response to decreased oxygen levels. The cardiovascular system increases heart rate to improve oxygen delivery to tissues. This finding alone does not indicate treatment failure but should be monitored for trends.

D. Occasional cough without sputum production is generally not an urgent finding in this context. It may reflect airway irritation or underlying lung pathology but does not directly indicate worsening oxygenation or respiratory failure. It becomes more significant only if associated with increased work of breathing or declining oxygen saturation.
