Question 1

When a sequential compression device is brought in, it is seen that the sleeve pressure is low. What needs to be checked first?

Accepted Answer

Check the chambers and tubing for leaks

Answer

A sequential compression device (SCD) operates by inflating and deflating air chambers within a sleeve to promote blood circulation. If the sleeve pressure is low, the most common and immediate cause is a leak within the system. Therefore, checking the chambers and tubing for any leaks is the crucial first step in troubleshooting, as any breach would prevent the device from maintaining the intended therapeutic pressure.

Question 2

Which of the following features is exclusive to invasive blood pressure measurement as opposed to non-invasive?

Accepted Answer

Hypotensive blood pressure can be monitored

Answer

Invasive blood pressure measurement, typically via an arterial line, provides continuous, beat-to-beat blood pressure readings. This method is particularly vital for accurately monitoring patients with unstable hemodynamics, such as those experiencing severe hypotension, where non-invasive methods may be unreliable or insufficient. The continuous and precise data from invasive monitoring allows for immediate detection and management of critical blood pressure changes, which is a key advantage over non-invasive methods.

Question 3

A hypothermia/hyperthermia machine is sent to Biomed for inspection. According to reports, the device does not deliver the desired level of cooling or heating in either mode. A cursory inspection confirms that there are no leaks in the blanket being used, and the gadget is receiving the proper power supply. What else could be causing this problem?

Accepted Answer

Insufficient flow rate

Answer

A hypothermia/hyperthermia machine relies on circulating fluid through a blanket to effectively transfer heat. If the device is not delivering the desired level of cooling or heating, and there are no leaks or power issues, an insufficient flow rate of the circulating fluid is a very common cause. A reduced flow rate means less thermal energy is being transferred to or from the patient, leading to ineffective temperature regulation.

Question 4

Which of the following is a manual blood pressure auscultation device?

Accepted Answer

Manometer

Answer

A manometer is a key component of a manual blood pressure auscultation device, specifically a sphygmomanometer. It is the gauge that measures the pressure within the inflatable cuff, allowing the healthcare professional to read the systolic and diastolic blood pressure values. While Korotkoff sounds are listened for, the manometer provides the actual pressure measurement.

Question 5

A sphygmomanometer with the warning that the pressure reading is usually excessive is brought in for duty. What is the MOST suitable procedure to inspect the device?

Accepted Answer

Perform a test run on the device on a noninvasive blood pressure simulator

Answer

When a sphygmomanometer is reported to give excessive pressure readings, the most accurate inspection procedure is to use a noninvasive blood pressure (NIBP) simulator. This specialized device can generate precise, known blood pressure values, allowing the technician to objectively verify the accuracy of the sphygmomanometer's measurements against these controlled standards. This method ensures a reliable assessment of the device's calibration and function.
