The nurse should recognize which pathophysiologic disease process(es) is/are related to an altered immune system? (Select all that apply)

Choice A reason: Cholinergic responses involve acetylcholine-mediated parasympathetic effects, like salivation, not burn injury reactions. Severe burns trigger a massive inflammatory response, releasing cytokines and histamine to combat tissue damage. This choice is incorrect, as cholinergic activity is unrelated to the systemic response to burns.

Choice B reason: Severe burn injuries initiate a profound inflammatory response, with cytokine release, histamine, and vasodilation to repair damaged tissue and fight infection. This systemic reaction causes edema, pain, and immune activation, aligning with burn pathophysiology. Inflammation is the primary initial response, per burn care evidence.

Choice C reason: Anaphylactic responses involve IgE-mediated allergic reactions, not burn injuries. Burns cause inflammation from tissue trauma, not allergen-driven mast cell degranulation. This choice is incorrect, as anaphylaxis is unrelated to the pathophysiological cascade triggered by severe thermal injury to the skin and tissues.

Choice D reason: Noncompensatory responses imply unrecoverable shock, not the initial burn reaction. Burns trigger compensatory inflammation to stabilize tissue damage. Noncompensatory states may occur later in severe cases, but the initial response is inflammatory, making this incorrect for describing the body’s immediate reaction to burns.

Choice A reason: Insulin reduces serum glucose in diabetes mellitus, not water loss in diabetes insipidus (DI). DI results from vasopressin deficiency, causing excessive urination. Insulin is irrelevant, as DI is a fluid balance disorder, not a glucose metabolism issue, making this response incorrect and misleading for the client.

Choice B reason: Assessing dietary habits and glucose levels pertains to diabetes mellitus, not diabetes insipidus. DI involves water loss due to vasopressin deficiency, not glucose dysregulation. This response misaligns with DI’s pathophysiology, as insulin or glucose monitoring is unnecessary, and vasopressin therapy is the standard treatment.

Choice C reason: Maintaining normal serum glucose is a goal for diabetes mellitus, not diabetes insipidus, which involves water loss from vasopressin deficiency. DI treatment focuses on fluid balance via vasopressin, not glucose control. This response is incorrect, as it conflates DI with an unrelated metabolic condition.

Choice D reason: Diabetes insipidus is managed with vasopressin (ADH) therapy to reduce excessive urination and conserve water, addressing the underlying deficiency. This response accurately explains DI’s treatment, distinguishing it from diabetes mellitus and clarifying that insulin is not needed, aligning with evidence-based endocrinology practice for fluid balance.
