Explanation

The image displays an incentive spirometer, a handheld medical device used to promote deep breathing and optimal lung expansion.
Its key features are a mouthpiece connected to a clear plastic chamber with volume indicators and a piston or ball that rises during inhalation, which are clearly visible.
The primary clinical purpose is to prevent postoperative pulmonary complications such as atelectasis (lung collapse) by encouraging sustained maximal inspiration.

Option B: A PET machine is a large, donut-shaped diagnostic imaging scanner used in radiology to observe metabolic processes. It is not a small, handheld respiratory device.
Option C: A spacer is a hollow tube that attaches to a metered-dose inhaler (MDI) to improve the delivery of aerosolized medication. It does not have the volume measurement chambers or moving piston seen in the image.
Option D: A Venturi mask is an oxygen delivery device that fits over the patient's nose and mouth. It has color-coded diluter jets to provide a precise fraction of inspired oxygen (FiO2) and looks distinctly like a mask.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification and use of respiratory therapy equipment as background academic context rather than a clinical decision trigger.
Nurses are responsible for teaching patients how to use the incentive spirometer correctly, especially after surgery (e.g., abdominal or thoracic) to prevent lung complications.
Patient education should emphasize inhaling slowly and deeply, holding the breath, and performing the exercises regularly (e.g., 10-15 times per hour while awake).
To manage pain during use, nurses should instruct patients to splint their incision with a pillow and ensure adequate pain medication is administered beforehand.

How to Approach the Question

First, carefully observe the device in the image. Note its distinct features: a mouthpiece, a flexible tube, and a clear chamber with markings and an internal moving part (piston/ball).
Consider the function implied by these features. The design strongly suggests a device for measuring or encouraging a specific type of breathing (inhalation, given the piston rises).
Evaluate the given options. 'Incentive spirometry' refers to the use of a device that encourages inspiration (an incentive). This matches the visual evidence.
Systematically eliminate the other options by recalling what they are. A PET machine is for imaging, a spacer is for inhalers, and a Venturi mask is for oxygen delivery. None of these match the object in the image.
