A patient receiving intravenous chemotherapy begins to complain of intense pain and swelling at the IV site.

Upon assessment, the nurse notes redness and warmth in the area.

What is the most appropriate initial nursing intervention?

Choice A rationale

The fundamental principle of preventing graft rejection involves the pharmacological suppression of the recipient immune system. Immunosuppressive medications, such as corticosteroids, calcineurin inhibitors like tacrolimus, and antimetabolites like mycophenolate mofetil, work by inhibiting T-cell activation and proliferation. By reducing the immune response against the non-self HLA antigens of the donor kidney, these drugs prevent the body from attacking the new organ. This lifelong therapy is essential for maintaining long-term graft survival.

Choice B rationale

Chronic rejection is a slow, progressive immunological and non-immunological process resulting in irreversible fibrosis and scarring of the renal parenchyma. Unlike acute rejection, which often responds to increased doses of immunosuppressants or pulse steroids, chronic rejection is generally refractory to augmented immunosuppression. Management focuses on controlling blood pressure, managing lipids, and optimizing current medication levels to slow the decline of renal function rather than reversing the underlying chronic damage already sustained by the organ.

Choice C rationale

Comprehensive postoperative education is a critical component of transplant success and patient safety. Patients must understand the physiological signs of rejection, such as fever, decreased urine output, and graft tenderness, to seek medical intervention immediately. Lack of education increases the risk of medication non-adherence and delayed recognition of complications. Understanding the rejection process empowers patients to participate in their care, which significantly correlates with improved long-term clinical outcomes and graft longevity.

Choice D rationale

Clinical presentations vary significantly based on the timing and mechanism of rejection. Hyperacute rejection occurs within minutes due to preformed antibodies, leading to immediate thrombosis. Acute rejection, occurring days to months later, may present with systemic symptoms like fever and elevated creatinine levels. Chronic rejection is often asymptomatic initially, manifesting only as a gradual decline in the glomerular filtration rate over years. Therefore, nurses must teach that symptoms are not uniform across all types of rejection.

Choice E rationale

Hyperacute rejection is a type II hypersensitivity reaction caused by pre-existing antibodies against the donor's ABO blood group or HLA antigens. This results in immediate complement activation, massive intravascular coagulation, and hemorrhagic necrosis of the graft. Because this process is irreversible and occurs almost instantly upon anastomosis of the vessels, the only clinical intervention is the immediate surgical removal of the transplanted kidney to prevent systemic inflammatory response syndrome and further life-threatening complications.

Choice F rationale

Dialysis is not a universal requirement for monitoring or managing all rejection episodes. While dialysis may be necessary if a rejection episode leads to severe acute kidney injury or complete graft failure, many acute rejection episodes are successfully managed with high-dose intravenous medications without the need for renal replacement therapy. Monitoring graft function primarily involves serial measurements of serum creatinine, blood urea nitrogen, and urine output, alongside renal biopsies, rather than the routine use of dialysis.

Choice A rationale

Diarrhea is not a primary or life-threatening complication associated with medications that stimulate platelet production, such as oprelvekin or thrombopoietin receptor agonists. While gastrointestinal upset can occur with many medications, it does not represent the significant physiological risks targeted by nursing surveillance in this specific therapy. The focus of monitoring for these agents is centered on fluid balance and vascular integrity, as these drugs significantly impact intravascular osmotic pressure and the coagulation cascade through increased cellular production.

Choice B rationale

Nausea and vomiting are common side effects of many systemic therapies but are not considered the most critical or specific complications of platelet-stimulating agents. These symptoms are generally managed with antiemetics and do not typically require the cessation of therapy. When managing a patient on oprelvekin, the nurse prioritizes monitoring for systemic inflammatory responses and fluid retention over mild gastrointestinal distress, as the latter does not usually lead to long-term morbidity or acute cardiovascular collapse in this context.

Choice C rationale

Stimulating the production of platelets, or thrombopoiesis, carries a significant risk of inducing a prothrombotic state where blood clots may form. When the platelet count rises rapidly or exceeds the normal range of 150,000 to 450,000 cells/uL, the risk for deep vein thrombosis, pulmonary embolism, or myocardial infarction increases. The nurse must assess for signs of vascular occlusion, including localized edema, redness, and sudden chest pain, as the increased cell density enhances blood viscosity and clotting.

Choice D rationale

Bone fractures are not a typical complication of platelet-stimulating therapy. While some colony-stimulating factors can cause bone pain due to the expansion of bone marrow, they do not generally lead to acute structural failure or pathological fractures. Bone marrow stimulation is a physiological process that occurs within the medullary cavity and, while uncomfortable, does not degrade the mineral density of the cortical bone. Nursing care focuses on pain management rather than fall precautions related to skeletal fragility in these patients.

Choice E rationale

Pulmonary edema is a severe complication specifically linked to oprelvekin therapy due to its tendency to cause sodium and water retention. The resulting expansion of plasma volume increases hydrostatic pressure within the pulmonary capillaries, leading to fluid shifting into the alveoli. The nurse must monitor for dyspnea, crackles upon auscultation, and decreased oxygen saturation. This fluid shift can lead to acute respiratory distress syndrome, making frequent cardiovascular and respiratory assessments essential for early detection of fluid overload.
