In the following statements, which one is FALSE?

Correct! Wrong!

Explanation:
In accordance with NFPA 99, household electronics without conductors are OK as long as they are not near patient care areas and are doubly insulated otherwise. NFPA 99 demands that any equipment that will be used close to patients be inspected, defective equipment must be removed, and leakage current must be tested.

Which of the following best sums up the function of PING?

Correct! Wrong!

Explanation:
To test a connection, use the PING utility to send a message and have it returned. Numerous statistics are gathered on the quantity of echoed messages received and the processing time. PING is a networking tool—not a physical tool—that only repeats certain messages; it does not repeat all messages received. The PING tool has nothing to do with ultrasonography.

The usage of a pressured flow blood warmer has been reported to make a lot of noise. Which is NOT the most probable reason for this complaint?

Correct! Wrong!

Explanation:
A pressurized flow warmer accelerates the flow of blood by applying external pressure to blood bags using a compressor and pressure chamber. Loud noise production is a typical indicator of a defective compressor or an internal worn-out or loose component. Similar to the last example, if an assembly's components or screws are too loose, they may vibrate excessively and cause a rattle or hum. In non-pressurized flow warmers, a peristaltic pump may be utilized, but not in this instance, and it would not account for the loud noise.

What type of hypo/hyperthermia machine uses which thermoregulation technique?

Correct! Wrong!

Explanation:
In order to control the patient's temperature, hypothermia and hyperthermia machines feed heated or chilled water through specific blankets with weight tubes.

Which of the following elements is found in the hemodialysis circuit after filtration?

Correct! Wrong!

Explanation:
One of the final parts of the hemodialysis circuit, the air trap is utilized to identify air bubbles and prevent them from entering the patient's circulation. The blood pressure entering the dialyzer is measured by the dialyzer pressure monitor. One of the first parts of the circuit outside the body that moves blood through the circuit is the blood pump. Heparin, an anticoagulant, is infused into the blood by the heparin pump before it is filtered in the dialyzer.

In which one of the following muscle types are the filaments disorganized?

Correct! Wrong!

Explanation:
Smooth muscle is not striated like the other two types of muscle—cardiac and skeletal—it is considered to be arranged in an ad hoc manner. occur as a result of how the repetitive functional components of striated muscle, called sarcomeres, are arranged. Usually, the supporting tissues of hollow organs and blood arteries contain smooth muscle. Only the heart contains cardiac muscle, which is what causes the contractions that pump blood throughout the body. The movements of the skeleton are controlled by skeletal muscles, which are by far the most numerous in the body. All voluntary motion is produced by the contraction of skeletal muscles. Rough muscles on the thighs don't exist.

Which of the following does NOT arise frequently from utilizing heart-lung machines?

Correct! Wrong!

Explanation:
Heparin is used to thin the blood in circulation to stop clotting. In order to lower the patient's temperature and metabolic rate, blood temperatures were purposefully lowered. Utilizing certain centrifugal or peristaltic pumps, blood is gently sent back to the patient to reduce blood damage. The machines have backup pumps because a pump failure could put the patient in danger.
