- D.
Brachial nerve damage
Correct Answer
A. Compromised respirationExplanation
In the prone position, the thorax must be elevated from the OR table to prevent compromised respiration. This is because when a patient is lying face down, there is a risk of restricted breathing due to the weight of the body compressing the chest and abdomen. Elevating the thorax helps to alleviate this pressure and allows for proper airflow, ensuring adequate respiration during the procedure.Rate this question:

The anesthesiologist closes the eyelids of a general anesthetic patient for all of the following reasons EXCEPT
- A.
Prevent drying of the eye
- B.
Prevent the patient from seeing the procedure
- C.
Prevent eye trauma
- D.
Protect the eye from anesthetic agents
Correct Answer
B. Prevent the patient from seeing the procedureExplanation
The anesthesiologist closes the eyelids of a general anesthetic patient to prevent drying of the eye, prevent eye trauma, and protect the eye from anesthetic agents. However, closing the eyelids does not prevent the patient from seeing the procedure, as the patient is under general anesthesia and is unconscious during the surgery.Rate this question:

Diastolic blood pressure refers to
- A.
The force created by the contraction of the left ventricle of the heart
- B.
The relaxation phase between heartbeats
- C.
The first sound heard when taking the pressure on a manometer
- D.
The high point of the cycle
Correct Answer
B. The relaxation pHase between heartbeatsExplanation
Diastolic blood pressure refers to the relaxation phase between heartbeats. This is the period when the heart is at rest and the blood is flowing back into the heart. During diastole, the heart muscles relax, allowing the chambers to fill with blood. The diastolic blood pressure measurement indicates the pressure in the arteries when the heart is at rest, and it is an important indicator of cardiovascular health.Rate this question:

Systolic blood pressure represents
- A.
The pressure in the heart chambers, great vin, or close to the heart
- B.
The relaxation phase between heartbeats
- C.
The low point of the cycle
- D.
The greatest force caused by contraction of the left ventricle of the heart
Correct Answer
D. The greatest force caused by contraction of the left ventricle of the heartExplanation
Systolic blood pressure represents the greatest force caused by contraction of the left ventricle of the heart. This is the highest pressure in the arteries when the heart beats and pumps blood out. It is an important measure of cardiovascular health and indicates the force exerted on the arterial walls during each heartbeat.Rate this question:

Tachycardia is a (n)
- A.
Heartbeat over 100 beats per minute
- B.
Irregular heartbeat
- C.
Thready, weak heartbeat
- D.
Heartbeat less than 60 beats per minute
Correct Answer
A. Heartbeat over 100 beats per minuteExplanation
Tachycardia is a condition characterized by a heartbeat that exceeds 100 beats per minute. This means that the heart is beating faster than the normal range, which is typically between 60 to 100 beats per minute. Tachycardia can be caused by a variety of factors, such as stress, exercise, certain medications, or underlying medical conditions. It can lead to symptoms like palpitations, dizziness, shortness of breath, and chest pain. Treatment for tachycardia depends on the underlying cause and may involve medication, lifestyle changes, or medical procedures.Rate this question:

The most common artery used to feel the pulse is the
- A.
Dorsalis pedis artery
- B.
Femoral artery
- C.
Radial artery
- D.
Carotid artery
Correct Answer
C. Radial arteryExplanation
The radial artery is the most common artery used to feel the pulse because it is easily accessible and located close to the surface of the skin. It is located on the thumb side of the wrist and is commonly used to check the pulse rate. The dorsalis pedis artery is located on the top of the foot and is not as commonly used for pulse measurement. The femoral artery is located in the groin area and is typically used in medical emergencies. The carotid artery is located in the neck and is used in emergency situations when the patient is unconscious or unresponsive.Rate this question:

The body temperature taken orally is 98.6 F. What is it in Celsius?
- A.
37 C
- B.
52 C
- C.
110 C
- D.
212 C
Correct Answer
A. 37 CExplanation
The correct answer is 37 C. This is because the conversion formula from Fahrenheit to Celsius is (F - 32) * 5/9. By plugging in 98.6 for F, we get (98.6 - 32) * 5/9 = 37 C.Rate this question:
