A client with chronic kidney disease has a low red blood cell count. What is the best response by the nurse?

Choice A reason: Chronic kidney disease (CKD) does not primarily cause anemia by leaking red blood cells (RBCs) into urine. While hematuria may occur in some renal conditions, anemia in CKD results mainly from reduced erythropoietin production, not RBC loss. This statement is inaccurate, as it misrepresents the primary mechanism of anemia in CKD.

Choice B reason: Inflammation in CKD may contribute to anemia by suppressing erythropoiesis through cytokine release, but it does not directly attack RBCs. The primary cause is erythropoietin deficiency due to impaired renal function. This statement is inaccurate, as it overstates inflammation’s role and ignores the key hormonal mechanism in CKD-related anemia.

Choice C reason: High vascular pressure in CKD can damage kidneys but does not directly cause RBCs to burst (hemolysis). Anemia in CKD stems from reduced erythropoietin, not mechanical RBC destruction. This statement is inaccurate, as it incorrectly links hypertension’s renal effects to direct RBC damage, misrepresenting the anemia’s cause.

Choice D reason: CKD causes anemia due to reduced erythropoietin synthesis by damaged kidneys. Erythropoietin stimulates RBC production in bone marrow. In CKD, impaired renal function decreases erythropoietin, leading to anemia. This statement is accurate, as it correctly identifies the hormonal deficiency as the primary cause of low RBC counts in CKD.

Choice A reason: Acetaminophen reduces fever by acting on the hypothalamic thermoregulatory center but is ineffective for heat stroke, a hyperthermic emergency caused by environmental heat overload. It does not address core temperature elevation or systemic effects like dehydration and organ dysfunction, making it inappropriate for immediate heat stroke management.

Choice B reason: Removing the client’s clothing facilitates evaporative and convective cooling, critical in heat stroke where core body temperature exceeds 40°C. This intervention enhances heat dissipation from the skin, reducing the risk of organ damage from hyperthermia. It is a primary nursing action to lower body temperature effectively and safely.

Choice C reason: Placing a client with heat stroke in a hot bath would exacerbate hyperthermia, worsening organ damage and cardiovascular strain. Heat stroke requires rapid cooling via cold water immersion or evaporative methods, not additional heat exposure, making this intervention dangerous and contraindicated in this life-threatening condition.

Choice D reason: Encouraging oral fluids like cold water is inappropriate for a lethargic heat stroke patient, who may have impaired swallowing or consciousness, risking aspiration. Intravenous fluids are preferred to correct dehydration and electrolyte imbalances safely, as oral intake does not address the urgent need for rapid cooling and systemic stabilization.
