Which of the following features is exclusive to invasive blood pressure measurement as opposed to non-invasive?
Explanation:
The advantage of intra-arterial (invasive) blood pressure (IBP) is that it can continuously update the patient on their blood pressure, even when it is low. An alternative to invasive blood pressure monitoring, continuous noninvasive blood pressure (CNAP) provides continuous feedback. Noninvasive blood pressure measurements might vary greatly depending on the user's technique and how the patient is positioned. Systolic and diastolic blood pressure are measured by both techniques.
Which of the following aspects of healthcare is under the primary control of the Centers for Medicare and Medicaid Services (CMS)?
Explanation:
The CMS is a government organization that manages the Medicare and Medicaid programs and works to keep health insurance coverage accessible and reasonably priced. The International Organization for Standardization (ISO), not CMS, provides guidelines for quality improvement. CMS does not regulate the accreditation of research laboratories or healthcare facilities.
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?
Explanation:
The detector may suggest that there is no feeding set present due to excessive light, however this problem would not trigger a low flow warning. While kinked or clamped tubing would limit actual flow, creating a low flow error, coated drip camber would block the sensor. The pump's sensor may not detect the flow and may also indicate an error if the chamber was inserted incorrectly or became loose subsequently.
Which of the following is a manual blood pressure auscultation device?
Explanation:
The purpose of a manual sphygmomanometer is blood pressure auscultation. It comprises of an inflatable cuff to limit blood flow, a manometer to measure the pressure inside the cuff, and a method to detect the return of blood flow by listening for Korotkoff sounds with a stethoscope. Invasive blood pressure measurement methods that measure blood pressure directly as opposed to using auscultation often include a blood pressure transducer and cannula.
When a sequential compression device is brought in, it is seen that the sleeve pressure is low. What needs to be checked first?
Explanation:
With inflatable sleeves, especially sequential compression devices, leaks in the inflatable chambers are a common problem (SCDs). If it is determined that the device has no tubing or sleeve leaks, it may be required to verify the pump's ability to produce enough pressure as well as the low-pressure and pressure gauges.
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?
Explanation:
Only half of the issues reported are due to a malfunctioning heater or chiller since neither heating nor cooling modes achieve the appropriate thermoregulation. A crack or leak in the internal tubing is improbable because there isn't any standing water close to the device. Any number of root causes could result in an inadequate flow rate, which would slow down the pace at which heated or cooled water reaches the blanket and cause it to warm up more slowly than is ideal.
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?
Explanation:
The best diagnostic can be obtained by testing the device using a physiological simulator because a patient may not always be present and the precise cause may not be understood right away. Lower pressure readings, not greater ones, would come from any leak that needed to be fixed or replaced.
