HCA 201B MC Questions CORRECT
ANSWERS 2025
Respiratory arrest - CORRECT-ANSWERS-breathing stops
Respiratory depression - CORRECT-ANSWERS-breathing slows due to narcotics
Lung scans use - CORRECT-ANSWERS-radio isotopes
What is a pulmonary function test - CORRECT-ANSWERS-measures amount of air moving
into and out of the lungs
The process of respiration - CORRECT-ANSWERS-The respiratory system brings oxygen
into the lungs and removes carbon dioxide
Average heart rate of an adult is - CORRECT-ANSWERS-60 to 100 beats per minute
Respiration involves - CORRECT-ANSWERS-inhalation (inspiration) and exhalation
(expiration).
Breathing up right and forward is the - CORRECT-ANSWERS-orthopneic position
Tachypnea is - CORRECT-ANSWERS-rapid breathing Respirations are more than 24 per
minute
Bradypnea is slow breathing - CORRECT-ANSWERS-Respirations are fewer than 12 per
minute
Apnea is lack of or absence of breathing - CORRECT-ANSWERS-Sleep apnea and periodic
apnea of newborns are other types of apnea
Kussmaul respirations - CORRECT-ANSWERS-Deep and rapid respirations characteristic
of diabetic acidosis
Hypoventilation - CORRECT-ANSWERS-Respirations are slow, shallow, and sometimes
irregular
Hyperventilation - CORRECT-ANSWERS-Respirations are rapid and deeper than normal
Dyspnea - CORRECT-ANSWERS-Is difficult, laboured, or painful breathing
, Cheyne - CORRECT-ANSWERS-Stokes Respirations gradually increase in rate and
depth, and then become shallow and slow
Breathing may stop for 10 to 20 seconds,Cheyne - CORRECT-ANSWERS-Stokes respirations are
common when death is near
Orthopnea - CORRECT-ANSWERS-Is breathing deeply and comfortably only when
sitting
Nasal cannula - CORRECT-ANSWERS-you can eat while wearing it
Partial rebreather mask - CORRECT-ANSWERS-block the intake of the atmospheric air
only partially. Use of such masks result in patient breathing about 40% to 60%
concentration of oxygen.
Nonrebreather mask - CORRECT-ANSWERS-it is designed to prevent mixing of
atmospheric air or the air exhaled by the patient with the oxygen. This type of mask
allows up to 90% concentration of oxygen to be delivered
Venturi mask - CORRECT-ANSWERS-This type of mask increases the supply of total
oxygen for breathing, but the concentration of oxygen supplied is only about 24% to
28%
Thrombus - CORRECT-ANSWERS-Is a blood clot
The entire system from mouth to anus is how long - CORRECT-ANSWERS-30 feet (9 meters)
long
Accessory organs are - CORRECT-ANSWERS-the teeth, tongue, salivary glands, liver, gall
bladder, and pancreas.
Each nephron - CORRECT-ANSWERS-is the basic working unit of the kidney.
The healthy adult produces how much unrine a day - CORRECT-ANSWERS-1500 mL
