A nurse is caring for a client who has a history of hypertension. Which of the following findings should the nurse recognize is indicative of transient ischemic attacks?

Choice A reason: Hand tremors are not a primary symptom of anaphylaxis, which epinephrine treats. Tremors may occur from anxiety or other conditions, but epinephrine’s beta-adrenergic effects target airway dilation and vasoconstriction, not neurologic stabilization, making this unrelated to its acute therapeutic purpose.

Choice B reason: Shortness of breath, common in anaphylaxis, results from bronchoconstriction and airway swelling. Epinephrine acts on beta-2 receptors to relax bronchial smooth muscle, reversing dyspnea. This aligns with its primary use in allergic reactions, restoring oxygenation by counteracting histamine-induced distress.

Choice C reason: Nausea may accompany anaphylaxis due to systemic histamine release, but epinephrine does not directly treat it. Its focus is on reversing airway and vascular collapse, not gastrointestinal symptoms, which are secondary, making this an incidental, not primary, target of action.

Choice D reason: Hyperglycemia is not an anaphylactic symptom; epinephrine may raise blood sugar as a side effect via glycogenolysis, but this is irrelevant to its emergency use. It targets airway obstruction, not metabolic states, making this a misaligned choice for its therapeutic intent.

Choice A reason: Turning on overhead lights disrupts sleep by stimulating retinal photoreceptors, raising alertness via melatonin suppression. Scientifically, dim or red light preserves rest, making this contrary to reducing environmental stressors for sleep optimization in acute care settings.

Choice B reason: Rubber-soled shoes reduce noise from footsteps, minimizing auditory disturbances to sleep. Scientifically, quiet environments lower cortisol and enhance sleep quality, aligning with evidence-based stressor reduction strategies to promote rest in hospital clients effectively.

Choice C reason: Opening curtains increases light and noise exposure, disrupting sleep cycles via circadian misalignment. Scientifically, darkness supports melatonin production, so this heightens stressors, opposing the goal of improving rest in shared hospital rooms per sleep science.

Choice D reason: Shift reports near rooms raise noise levels, activating the hypothalamic-pituitary axis, disturbing sleep. Scientifically, quiet zones reduce awakenings, making this detrimental to stressor reduction, as it elevates auditory interference contrary to sleep promotion goals.
