that apply.) Correct Ans: Filtering. Humidifying. Warming.
2..During expiration, the intrapulmonary pressure causes air to flow out of
the lungs for which reason? Correct Ans: Because the intrapulmonary
pressure is higher than atmospheric pressure

surface tension
4.What is the primary function of type II alveolar cells? Correct Ans:
Surfactant production
5.Pressure gradient affects the diffusion of gases in which way? Correct
Ans: The greater the difference, the more rapid the gas flow

oxygen and hemoglobin? Correct Ans: Oxygen binds loosely and
reversibly to hemoglobin.
8.On the oxyhemoglobin dissociation curve, at a PaO2 less than 60
mmHg, any change in PaO2 yields how much of a change in SaO2?
Correct Ans: A large change
9.Which statement is true regarding the relationship of ventilation to
perfu- sion in an upright person? Correct Ans: It varies throughout the

remaining lung fields are clear. It is time to reposition the client in bed. Of
the following posi-tions, which is most likely to optimize the ventilation-
perfusion relation- ship? Correct Ans: Lying on the right side
11.Normal blood flow past completely unventilated alve-oli is the definition
of which term? Correct Ans: Capillary shunt
12.Oxygen therapy is most effective in treating which condition? Correct
Ans: Shuntlike effect
13.Respiratory compensation involves the excretion or retention of which
gas or substance? Correct Ans: CO2
14. Metabolic compensation involves changes in the renal excretion or
resorp- tion of which combination of gases or substances? Correct Ans:
HCO3, H+
15.Client situations associated with respiratory alkalosis include which
con- dition? Correct Ans: Anxiety
16.Which condition may cause metabolic acidosis because of a decrease
in bicarbonate levels? Correct Ans: Diarrhea

17.Normal values for arterial blood gases include which value? Correct
Ans: HCO3 26 mmHg
18.An increase in bicarbonate would have which effect
on the pH? Correct Ans: More alkaline

of 73 mmHg. Which classification of hypoxia exists? Correct Ans: Mild
, NUR 423 Exam 2 Book/quiz question practice
20.What factor must always be evaluated to place ABGs in the proper
con- text? Correct Ans: Client status
21.When a client is admitted in acute respiratory distress, the initial
history should focus on which priority? Correct Ans: Events leading to
current admission
22.What are the most common complaints associated with pulmonary dis-
ease? (Select all that apply.) Correct Ans: Cough. Sputum. Dyspnea E.
Chest pain
23.How is the chest pain typical of pleuritic pain best characterized? Correct
Ans: Sharp
24.What is the cause of crackles? Correct Ans: Fluid or secretions in
the small airways or alveoli
25.In the acutely ill client, pulmonary function testing helps monitor for
which condition? Correct Ans: Impending ventilatory failure
26.Minute ventilation VE is calculated using which formula? Correct Ans: VE
- VT x F
27.Clients who have obstructive pulmonary disease have which pattern
of FEVs? Correct Ans: Delayed FEVs
28.In the adult client, the nurse would become concerned that the client
is hypoventilating if the tidal volume falls to below which value? Correct
Ans: 4 mL/kg
29.What is pulse oximetry used to measure? Correct Ans: Arterial oxygen
capillary hemoglo- bin saturation
30.Which conditions impair the accuracy of pulse oxime-try? (Select all
that apply.) Correct Ans: Excessive movement .Hypothermia E. Improper
sensor placement
31.EtCO2 is an indicator of which alveolar factor? Correct Ans: Ventilation
32.Colorimetric capnography uses what measure to esti-mate EtCO2?
Correct Ans: pH
33.A client has developed a pulmonary problem that has resulted in de-
creased lung compliance. How will this affect the client's respiratory
system?-
Correct Ans: It will increase the client's work of breathing.
34.A client who has developed right middle-lobe pneumo-nia will
experience decreased ventilation in the affected lung areas for which
reasons? (Select all that apply.) Correct Ans: The pressure gradient is
abnormal. Gas follows the path of least resistance. 5. The consolidation
in the tissues will increase the pressure.
