NUR 2090: RESPIRATORY SYSTEM EXAM QUESTIONS
AND ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
What are 4 major functions of the Respiratory System?
1. Supplying oxygen to the body for energy production
2. Removing carbon dioxide as a waste product of energy reactions
3. Maintaining homeostasis (acid-base balance) of arterial blood
4. Maintaining heat exchange
Describe the anatomy of the Lungs
The right lung has 3 lobes and its base sits up higher, while the left lung has 2 lobes.
Hypercapnia
excessive carbon dioxide in the blood
Hypoxemia
decreased level of oxygen in the blood, increases respiration
Aspiration
Breathing fluid, food, vomitus, or an object into the lungs
Diaphragm
Large, flat muscle at the bottom of the chest cavity that helps with breathing
aspiration pneumonia
caused by foreign matter that is inhaled into the lungs
glossopharyngeal nerve
, Cranial nerve 9, after surgery this needs to be checked to make sure your gag reflex is
working
upper respiratory tract
consists of the nose, mouth, pharynx, epiglottis, larynx, and trachea
lower respiratory tract
trachea, bronchi, lungs
Biforcation
split
Trachea
a large membranous tube reinforced by rings of cartilage, extending from the larynx to
the bronchial tubes and conveying air to and from the lungs; the windpipe.
base of the lung
lowest part of the lung, resting on the diaphragm
apex of the lung
tip or uppermost portion of the lung
Mediastinum
area between the lungs containing the heart, aorta, v
mediastinal shift
shift of central thoracic structures toward one side
tension pneumothorax (collapsed lungs)
A life-threatening collection of air within the pleural space; the volume and pressure
have both collasped the involved lung and caused a shift of the mediastinal structures to
the opposite side.
