  2. Place the child in knee-chest position.
    • Rationale:
  3. Lay the child supine
    • Rationale:
  4. Call for a crash cart.
    • Rationale:

Overview

Explanation

The correct answer is B because the knee-chest position decreases blood return to the heart and increases cardiac output. This intervention will relieve the cardiac load. Selection A, C, and D are incorrect as oxygen will not decrease the cardiac load, supine position will not help hemodynamics, and the crash cart is not called for since knee-chest may relieve the symptoms.
