Question #6 (Topic: Topic 1)
A pulmonary function technologist can calculate which of the following if values for pH, PaO2, SaO2, SvO2 PvO2, VO2, and Hb are obtained?
A. Cardiac output
B. RER
C. VD/VT
D. Stroke volume

Question #7 (Topic: Topic 1)
A 9-year-old girl had an FVC of 2.35 L1 year ago. She was 122 cm (4 ft) tall and weighed 29.5 kg (65 lb). Her current height is 127 cm (4 ft 2 in), and her weight is
34 kg (75 lb). The current FVC measurement is 2.20 L. The quality of both tests met ATS/ERS goals. A pulmonary function technologist should conclude the
change is
34 kg (75 lb). The current FVC measurement is 2.20 L. The quality of both tests met ATS/ERS goals. A pulmonary function technologist should conclude the
change is
A. Not significant since it is less than a 15% decrease.
B. Not significant since it is within normal test variability.
C. Significant since a decline is not expected.
D. Significant since her weight has changed.
Answer: C
Question #8 (Topic: Topic 1)
Which of the following may cause a reduction in end-tidal CO2?
A. Increased VD/VT ratio
B. Anxiety-induced hyperventilation
C. Exercise below the anaerobic threshold
D. Eating a high-protein diet
Answer: B

the following may explain this change?
1. The patient has achieved anaerobic threshold.
2. The measurement of the expired gas volumes is inaccurate.
3. O2 analyzer "phase delay" has increased.
4. There is a leak in the tubing or mouthpiece.
