1. A patient with heart failure presents with shortness of breath. What is the priority intervention?
A. Administer IV fluids
B. Elevate legs
C. Administer oxygen
D. Encourage ambulation
Answer: C. Administer oxygen
Rationale:
Shortness of breath in heart failure indicates impaired oxygenation due to fluid buildup in the lungs. The priority is to improve oxygen delivery by administering supplemental oxygen. While elevating legs may help circulation in some cases, it can worsen pulmonary congestion. IV fluids could increase fluid overload. Addressing airway and breathing always comes first in clinical priority, making oxygen administration the most appropriate initial intervention.
