Identify the following image?

Appeared in: NORCET 5 Prelims - Sept 2023 (Shift-1)

Explanation

The image displays an incentive spirometer, a handheld medical device used to promote deep breathing and optimal lung expansion.
It features a mouthpiece connected to a clear plastic chamber with volume indicators and a piston that rises during inhalation, matching the device shown.
The primary clinical purpose is to prevent postoperative pulmonary complications such as atelectasis by encouraging sustained maximal inspiration.

Option B: A PET machine is a large, donut-shaped imaging scanner used in radiology to detect metabolic activity, not a handheld respiratory device.
Option C: A spacer is a simple tube attached to a metered-dose inhaler to improve medication delivery to the lungs. It lacks the volume measurement chambers and piston seen in the image.
Option D: A Venturi mask is an oxygen delivery device that fits over the patient's nose and mouth to provide a precise fraction of inspired oxygen (FiO2). It does not match the handheld device shown.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common medical respiratory devices as background academic context rather than a clinical decision trigger.
Incentive spirometry is highly recommended following abdominal or thoracic surgeries to counteract the shallow breathing caused by pain and anesthesia, thereby preventing atelectasis.
Nurses play a crucial role in patient education, instructing them to inhale slowly and deeply, hold their breath for 3-5 seconds at maximal inspiration, and perform 10-15 breaths every hour while awake.
What if the patient experiences severe incisional pain during use? The nurse should teach the patient to splint the incision with a pillow and administer prescribed analgesics before the breathing exercises to facilitate effective use and patient comfort.

How to Approach the Question

First, carefully analyze the visual features of the device shown in the image.
Note the key components: a clear plastic chamber with volume markings, a flexible tube, and a mouthpiece. These are characteristic of a breathing exercise device.
Recall the different types of respiratory therapy equipment you have studied.
Compare the visual evidence with the descriptions of the options provided.
Eliminate options that do not match. A PET machine is a large scanner, a spacer is an inhaler attachment, and a Venturi mask is an oxygen mask.
Conclude that the device is an incentive spirometer based on its structure and function.
