Allied Health Certified Nursing Assistant (CNA) Practice Test

Elevating the head of the bed improves breathing by allowing the chest and diaphragm to expand more fully, keeping airways open and making it easier to take deep, effective breaths. This semi- or high-Fowler position, used as ordered, supports better ventilation and oxygenation. Keeping the bed flat can restrict chest expansion and shallow breaths; lying on the stomach with the head turned to the side can press on the chest and isn’t typically used to optimize breathing; lowering the head while on the side can misalign the airway and reduce breathing effectiveness. Follow the order and monitor comfort and breathing status after repositioning.
