Which option best represents a drug listed as a risk for respiratory failure and hypotension?

• A. Oxygen
• B. Nitroglycerin
• C. Albuterol
• D. Morphine

Answer: (D)

Opioid medications can slow breathing and lower blood pressure, so a drug like morphine fits as a risk for both respiratory failure and hypotension. Morphine acts on brainstem respiratory centers to reduce respiratory drive and tidal volume, increasing the chance of hypoventilation and respiratory failure, especially in patients with underlying lung issues or impaired consciousness. It also causes peripheral vasodilation and decreased sympathetic tone, which lowers arterial blood pressure. The other options don’t carry both risks: oxygen supports breathing rather than causing respiratory suppression or hypotension; nitroglycerin can lower blood pressure but doesn’t depress respiration; albuterol is a bronchodilator that may cause tachycardia or tremors but not respiratory failure from depression.
