Question

a nurse is reviewing the medical record of a client who asks about using propranolol to treat hypertension. the nurse should recognize which of the following conditions is a contraindication for taking propranolol? a asthma b glaucoma c hypertension d tachycardia

Explanation:

Propranolol is a non - selective beta - blocker. Beta - blockers can cause bronchoconstriction. Asthma is a condition characterized by bronchospasm and airway hyper - reactivity. Blocking beta - 2 receptors (which are involved in bronchodilation) in patients with asthma can exacerbate airway constriction and lead to life - threatening respiratory distress. Glaucoma can be treated with some beta - blockers (topical beta - blockers are used to reduce intra - ocular pressure). Hypertension is an indication for propranolol (as it can lower blood pressure by reducing cardiac output and inhibiting renin release). Tachycardia is also an indication (beta - blockers slow the heart rate by blocking beta - 1 receptors in the heart).

Answer:

A. Asthma
