Chest Tube Care Questions and Answers
(100% Correct Answers) Already Graded A+
What happens when the diaphragm contracts? [ Ans: ] It
moves down
-thoracic volume increases
What happens when the volume of a container increases? [
Ans: ] Pressure decreases
What happens when the volume of a container decreases?
[ Ans: ] Pressure increases
How does gas move? [ Ans: ] From the area of higher
pressure to the area of lower pressure
-ex: inhalation- area moves from atmosphere (higher
pressure) to lungs (lower pressure)
What happens during exhalation? [ Ans: ] Diaphragm
relaxes and moves up
-decrease in volume leads to intrapulmonary pressure
increase
-air flows from higher pressure (lungs) to lower pressure
(atmosphere)
What surrounds the lungs? [ Ans: ] Pleura- thin tissue that
is a continuous membrane and folds over itself
, What are the types of pleura? [ Ans: ] Parietal- lines chest
wall
Visceral- covers the lung
How are the parietal pleura and visceral pleura separated?
[ Ans: ] By small amount of pleural fluid which reduces
friction and allows pleura to slide easily during breathing
What is the pleural space? [ Ans: ] Potential space between
visceral and parietal pleura
What pressure is in the pleural space? [ Ans: ] Negative
pressure vacuum that keeps two pleura together and
allows lungs to expand and contract for air exchange
What happens when air or fluid gets into pleural space? [
Ans: ] Pressure gradient disappears and lung collapses
What are the types of disruptions to pleural space? [ Ans: ]
Hemothorax
Pneumothorax
Pleural effusion
Where are chest tubes placed? [ Ans: ] Into pleural space
What is the goal of chest tube therapy? [ Ans: ] -To
promote lung re-expansion
-Restore oxygen and ventilation
