What position should a patient be placed in when using incentive spirometry?

• A. Prone
• B. Semi-Fowler or High-Fowler's
• C. Supine
• D. Lateral decubitus

Answer: (B)

Placing the patient in a semi-Fowler or high-Fowler position optimizes chest expansion and diaphragmatic movement during incentive spirometry. Elevating the head of the bed to about 30 to 60 degrees allows the lungs to expand more fully, especially the lower parts, and makes slow, deep breaths easier to perform with the device. This upright posture helps generate a larger inspiratory volume, which the incentive spirometer is designed to guide and reinforce, aiding in preventing atelectasis after surgery or illness.

Lying flat can hinder expansion because the abdomen presses against the diaphragm, reducing inspiratory effort. Lying on one side or in a prone position can limit symmetric chest expansion and is generally not the standard position for incentive spirometry.
