The nurse is assessing a client with sickle cell disease (SCD) crisis. What priority client problem will the nurse expect?

Chronic kidney disease(CKD) involves the progressive loss of nephron function, leading to impaired fluid homeostasisand electrolyte regulation. Patients often experience sodium and water retention, which manifests as hypertension and systemic edema. Precise monitoring of hemodynamic parametersand weight is essential to detect fluid overload early and prevent acute complications such as pulmonary edema or heart failure.

Rationale:

A.Maintaining a consistent sleep and meal schedule is beneficial for general health and circadian rhythm regulation. However, it does not provide specific clinical data regarding the progression of renal dysfunction or fluid status. For a kidney disease patient, metabolic and fluid stability takes priority over the timing of daily routines during discharge education.

B.The nurse teaches the client to weigh themselves and take their blood pressure because these are the most sensitive indicators of fluid volume excess. Sudden weight gain (e.g., 2 pounds in 24 hours) often signifies fluid retention rather than tissue mass. Monitoring blood pressure is vital as the kidneys regulate systemic vascular resistance and fluid volume, and uncontrolled hypertension further accelerates renal damage.

C.Instructing a kidney disease patient to drink 2 L of fluid and urinate at specific times can be dangerous. Many renal patients are on strict fluid restrictionsto prevent circulatory overload. Fixed fluid intake goals must be individualized based on the stage of kidney failure and current glomerular filtration rate to avoid life-threatening hypervolemia.

D.While urine dipsticks can check for proteinuria and blood sugar monitoring is vital for diabetic nephropathy, they are not the universal priority for all kidney disease patients. Blood pressure and weight provide more immediate, actionable data regarding cardiovascular stability and fluid balance. These parameters are the standard requirements for self-management to prevent emergency readmissions.

Graft-versus-host disease(GVHD) is a complex immunological phenomenon occurring after allogeneic hematopoietic stem cell transplantation. It occurs when immunocompetent donor T-lymphocytesrecognize the recipient’s HLA antigens as foreign. This leads to a systemic cytotoxic immune responsedirected against the host's tissues, primarily affecting the skin, liver, and gastrointestinal tract, causing significant morbidity and potential mortality.

Rationale:

A.Comparing GVHD to a transfusion reaction is scientifically imprecise. A transfusion reaction typically involves the recipient's antibodies attacking the donor's red blood cells. In contrast, GVHD involves a cellular immune response where the graft itself becomes the aggressor against the host. This fundamental difference in the "attacker" and the "target" is a crucial distinction.

B.Stating that the patient's cells are fighting donor cells describes a classic transplant rejection. In rejection, the host's immune system identifies the graft as foreign and attempts to destroy it. GVHD is the functional opposite, where the donor’s immune cells survive the conditioning regimen and mount an attack against the immunocompromised recipient.

C.The nurse correctly explains that the donor's cellsare attacking the patient's cells. This is the hallmark of GVHD, where donor T-cells initiate an inflammatory cascade against host tissues. This explanation accurately conveys the unique "upside-down" nature of this immune complication, where the transplanted tissue perceives the host's body as the foreign invader.

D.Stating that donor cells "take over" due to immunosuppression is a vague and misleading simplification. While donor cells are intended to engraft and produce new blood cells, the term "taking over" does not explain the pathological destruction of host organs. The issue is not the presence of donor cells, but their aggressive, inappropriate immune activation.
