Which symptom is a listed sign of critically low oxygen delivery?

• A. Hypertension
• B. Rash
• C. Shortness of breath
• D. Increased appetite

Answer: (C)

When oxygen delivery to tissues becomes critically low, the body tries to pull in more oxygen by increasing the work of breathing, which presents as shortness of breath. Dyspnea reflects that the respiratory system is under strain to improve oxygen uptake and delivery to the heart and tissues. Hypertension can occur for many reasons and isn’t a specific sign of impaired oxygen delivery. A rash isn’t related to oxygen transport, and an increased appetite has no connection to acute oxygen status. So shortness of breath is the best indicator that oxygen delivery to the body's tissues is critically compromised.
