What should be done for severe respiratory distress if the patient is hypertensive?

• A. Administer Nitroglycerin 0.8 mg spray or tablet SL.
• B. Administer Lorazepam.
• C. Administer Albuterol inhaler.
• D. Give aspirin.

Answer: (A)

When severe respiratory distress occurs with high blood pressure, the breathing difficulty is often driven by fluid backing up into the lungs (pulmonary edema) from the heart. The best move is to quickly reduce the heart’s filling pressures so the lungs can clear more easily and oxygenation improves. Nitroglycerin acts as a powerful venodilator, lowering preload (and to a lesser extent afterload), which reduces left-ventricular filling pressures and pulmonary congestion. By dialing down that pressure, breathing becomes easier and chest pain from possible ischemia can also improve. A sublingual dose of 0.8 mg provides rapid vasodilation, and this is particularly helpful when the patient is hypertensive, as they have the hemodynamic reserve to tolerate a vasodilator—provided there isn’t hypotension or contraindications like recent use of PDE-5 inhibitors.

Other options don’t address the underlying issue as directly. Lorazepam can calm anxiety but doesn’t treat the cardiac cause and can suppress respiration. An albuterol inhaler targets bronchospasm and would be helpful if airway reactivity were the main problem, not when pulmonary edema from heart failure is driving distress. Aspirin is important if a heart attack is suspected, but it doesn’t rapidly relieve pulmonary edema or severe respiratory distress.
