The nurse knows that the adverse effects of a nonselective beta blocker are likely to be the most immediately life-threatening in which patient?

Choice A rationale Nonselective beta blockers can mask the symptoms of hypoglycemia, such as tachycardia and tremors, in patients with type 1 diabetes. This poses a significant risk as it can delay recognition and treatment of a dangerously low blood sugar level, which can lead to seizures, coma, and death. Choice B rationale Nonselective beta blockers block both beta-1 and beta-2 adrenergic receptors. Blocking beta-2 receptors in the lungs leads to bronchoconstriction, which can trigger a severe, life-threatening asthma attack (status asthmaticus) by narrowing the airways and making breathing extremely difficult. Choice C rationale Nonselective beta blockers can decrease lower esophageal sphincter tone and may worsen acid reflux symptoms. While uncomfortable, this effect is not typically considered an immediately life-threatening adverse event and can be managed by diet, lifestyle changes, and other medications. Choice D rationale While nonselective beta blockers are used to treat hypertension, they can cause adverse effects like bradycardia or hypotension. However, these effects are usually manageable and not as immediately life-threatening as the bronchoconstriction that can be induced in a patient with asthma.
