NSG 262 Exam 2 Review Questions
and All Correct Answers 2026
Updated.
Compliance - Answer the ability of the lungs to distend or expand in response to increased
intra-alveolar pressure
> decreases in diseases like pulmonary edema or with injuries like fractured ribs
Airway Resistance - Answer the increase in pressure that occurs as the diameter of the
airways decreases from mouth/nose to alveoli
> this decreases the amount of oxygen delivered to the alveoli
Oxygen Demand - Answer how much oxygen the body needs for an a certain activity level
Chronic Diseases that affect oxygenation - Answer > COPD
> asthma
> bronchitis
Conditions that affect chest wall movement that ultimately affect oxygenation - Answer >
pregnancy
> obesity
> neuromuscular disease
> trauma
Surfactant - Answer chemical produced in the lungs to maintain the surface tension of the
alveoli and keep them from collapsing
> "alveoli are coated with it"
Hyperventilation - Answer breathing too fast
> loss of CO2
Hypoventilation - Answer breathing too slow
> too much CO2
Hypoxia - Answer insufficient oxygen supply to the tissues at a cellular level
, Hypercapnia - Answer excessive carbon dioxide in the blood
> caused by hypoventilation
Hypovolemia - Answer low blood volume
> caused by hemorrhage
Atelectasis - Answer collapse of alveoli (collapsed lung)
Anemia - Answer lack of a normal number of red blood cells
CP - Answer chest pain
Dyspnea - Answer difficulty breathing
Orthopnea - Answer difficulty breathing when lying down
Wheezing, Rales, Rhonchi - Answer harsh lung sounds
If patient has a cough, what should be the first thing assessed? - Answer "is it productive?"
Semi-Fowlers Position - Answer most effective position for promotion of lung expansion
Coughing and deep breathing are techniques that.... - Answer protect the alveoli and
promote lung expansion
Incentive Spirometry - Answer method of encouraging voluntary deep breathing by
providing visual feedback to patients of the inspiratory volume they have achieved
Nasal Cannula - Answer > 1-6 L/min
> 24-44% O2
> does NOT impede eating or talking
> can dislodge easily
> can cause skin breakdown and irritation of backs of ears of patient
Simple Face Mask - Answer > 6-12 L/min
