Appeared in: NORCET 5 mains

Explanation

The device shown in the image is an aneroid sphygmomanometer, also known as an aneroid BP apparatus.
It is clearly identified by its three main components: an inflatable arm cuff, a circular dial gauge for reading pressure, and a rubber bulb for manual inflation.
This equipment is used for the non-invasive measurement of a patient's arterial blood pressure.
The term 'aneroid' means 'without fluid,' indicating that it uses a mechanical mechanism with a spring and gears to measure pressure, unlike older mercury-based models.

Option B: A handheld endotracheal (ET) tube pressure cuff manometer is a much smaller, specialized device used to measure the pressure within the cuff of an ET tube to prevent tracheal injury. It is not used for measuring systemic blood pressure and has a different pressure scale and connection.
Option C: A gas cylinder measure, or pressure regulator, is a robust device attached to the valve of a medical gas cylinder (e.g., oxygen) to measure the high pressure inside the tank and regulate the flow of gas to the patient. It looks very different from the device shown.
Option D: This option is incorrect because the device in the image is clearly identifiable as an Aneroid BP apparatus, which is listed as option A.

Visual 1: Diagram - A labeled diagram showing the parts of an aneroid sphygmomanometer: cuff, bladder, tubing, aneroid manometer (dial), and inflation bulb with release valve. This helps learners identify each component.
Visual 2: Comparison Chart - An infographic comparing the appearance and use of an aneroid BP apparatus, a handheld ET cuff manometer, and a gas cylinder regulator. This visually reinforces the differences between the devices.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common medical equipment used in nursing practice as background academic context rather than a clinical decision trigger.
Accurate blood pressure measurement is a fundamental nursing skill critical for diagnosing hypertension, assessing cardiovascular risk, and monitoring patient stability.
Nurses must select the correct cuff size. An improperly sized cuff is a common source of error. A cuff that is too small will result in a falsely high reading, while a cuff that is too large will give a falsely low reading.
Aneroid manometers require regular calibration (typically every 6 months) to ensure accuracy. Nurses should be aware of their facility's policy and report any suspected equipment malfunction.

How to Approach the Question

This is an image-based identification question.
First, carefully observe the key features of the device in the image. Note the arm cuff, the round dial with a needle, the rubber tubing, and the squeeze bulb.
Next, consider the function of these components. The cuff is for occluding an artery, the bulb is for inflation, and the gauge is for measuring pressure. This points to a blood pressure measurement device.
Evaluate the given options. 'Aneroid BP apparatus' directly matches the visual evidence, as 'aneroid' refers to the type of dial gauge shown.
Rule out the other options by recalling what they are used for and what they look like. An ET cuff manometer is for airways, and a gas cylinder measure is for oxygen tanks; both have different appearances and functions.
Confirm that the identified device (Aneroid BP apparatus) is among the choices, making 'None of them' incorrect.
