Free Ultimate CBET Test Question and Answers — Questions and Answers
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?
- Check the chambers and tubing for leaks (Correct answer)
- Check the pressure gauge for the sleeve
- Check the function of the pump
- Check the circuitry to the alert light
Correct answer: Check the chambers and tubing for leaks
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?
- Performance of the method can affect the results
- A comparison between systolic and diastolic blood pressure can be made
- Hypotensive blood pressure can be monitored (Correct answer)
- It can provide continuous blood pressure measurements
Correct answer: Hypotensive blood pressure can be monitored
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?
- Insufficient flow rate (Correct answer)
- Cracked interior flow circuit
- Broken heating element
- Faulty chiller connection
Correct answer: Insufficient flow rate
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?
- Korotkoff sounds
- Cannula
- Manometer (Correct answer)
- Pressure transducer
Correct answer: Manometer
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?
- Visually inspect the sphygmomanometer's inflatable cuff and patch it
- Recalibrate the device's manometer and return to service
- Request a test of the device on another patient to examine it in use
- Perform a test run on the device on a noninvasive blood pressure simulator (Correct answer)
Correct answer: Perform a test run on the device on a noninvasive blood pressure simulator
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.
Question 6: A new enteral feeding pump is placed into use, but it is soon sent to Biomed for repair. According to the complaint, it was operating normally until it started displaying a persistent low-flow error. Which of the following symptoms would NOT set off the alarm?
- Kinked or clamped tubing upstream of the pump
- Excessive ambient light by the feeding set detector (Correct answer)
- A dislodged drip chamber
- Feeding solution coating drip chamber walls
Correct answer: Excessive ambient light by the feeding set detector
Enteral feeding pumps often use optical sensors to detect fluid flow, such as a drip chamber sensor. Kinked tubing, a dislodged drip chamber, or feeding solution coating the drip chamber walls would directly impede flow or interfere with the sensor's ability to detect flow, thus triggering a low-flow alarm. Excessive ambient light, however, is generally unlikely to directly cause a low-flow error, as these sensors are typically designed to filter out ambient light or use specific light frequencies.
Question 7: Which of the following aspects of healthcare is under the primary control of the Centers for Medicare and Medicaid Services (CMS)?
- Accreditation and certification of healthcare facilities
- Publication of standards for quality improvement in organizations
- Overseeing healthcare insurance for small businesses and individuals (Correct answer)
- Accrediting research laboratories
Correct answer: Overseeing healthcare insurance for small businesses and individuals
The Centers for Medicare & Medicaid Services (CMS) is a federal agency responsible for administering the Medicare program and working with states to manage Medicaid, the Children's Health Insurance Program (CHIP), and health insurance marketplaces. Its primary control lies in overseeing these vast government healthcare programs, which provide health coverage to millions of Americans, including those in small businesses and individuals through the Affordable Care Act (ACA) marketplaces.
