What is the main problem with positive-pressure ventilation?
- cardiac output drops
- cardiac output
-there is a decrease in intrathoracic pressure
- hemothorax ------------Correct Answer--------------------cardiac output
drops
Which of the following is an indication of poor air exchange?
- stridor
- pneumothorax
,- gastric distention
- wheezing ------------Correct Answer--------------------stridor
You are performing mouth-to-mask ventilations with oxygen connected
and set at a flow rate of 15 L/min. What percentage of oxygen is your
patient receiving?
- 55%
- 75%
- 45%
- 65% ------------Correct Answer--------------------55%
What occurs when a patient is breathing very rapidly and shallowly?
- air is forcefully drawn into the lungs due to the negative pressure
created by the rapid respirations
,- the majority of tidal volume reaches the lungs and diffuses across the
alveolar-capillary membrane
- air moves primarily in the anatomic dead space and does not
participate in pulmonary gas exchange
- minute volume increases because of a marked increase in both tidal
volume and respiratory ------------Correct Answer--------------------air
moves primarily in the anatomic dead space and does not participate in
pulmonary gas exchange
Which of the following structures is NOT found in the upper airway?
- pharynx
- larynx
-orotharynx
- bronchus ------------Correct Answer--------------------bronchus
, The physical act of moving air into and out of the lungs is called:
- oxygenation
- diffusion
- respiration
- ventilation ------------Correct Answer--------------------ventilation
How does CPAP improve oxygenation and ventilation in patients with
certain respiratory problems?
- it pushes thick, infected pulmonary secretions into isolated areas of
the lung
- it forces the alveoli open and pushes oxygen across the alveolar
membrane
- it prevents albeolar collapse by pushing air into the lungs during
inhalation
