1. A patient with normal lungs The normal range for the FEV1 as a percent of the FVC
should be able exhale what per- (FEV1%) is 70-83%. Patients with
centage of the FVC obstructive pulmonary disease will show a reduction in timed
within one second after initiat- FEV% values, while
ing an Forced Vital Capacity ma- patients with restrictive disorders will generally exhibit nor-
neuver? mal (or sometimes high)
A. 35-50% of the FVC FEV% values.
B. 50-70% of the FVC
C. 70-83% of the FVC
The correct answer is: 70-83% of the FVC
D. 84-93% of the FVC
2. Simple spirometry can be used Residual volume is defined as the amount of air left in the
to measure any of the following lungs after a maximal
except: exhalation. Because the RV cannot be exhaled, it is impossible
A. vital capacity to be measured by
B. residual volume simple spirometry. And because the RV is a component of the
C. tidal volume FRC and TLC, simple
D. inspiratory reserve volume spirometry also cannot measure these capacities.
The correct answer is: residual volume

4. Which of the following thoracic The following are ultrasound findings consistent with the
ultrasound findings will show presence of an underlying
with the presence of pneumothorax: absence of the gliding sign and B-lines, and
a pneumothorax? the presence of A-lines and
A. presence of gliding sign (on M-mode) the barcode sign. A lung point sign (or lead
B. absence of A-lines point) also may be present in
C. presence of barcode sign patients with a pneumothorax, representing the transition
D. presence of seashore sign between an area where
pleural gliding is visible and where it stops (demarcating the
beginning of air in the
pleural space). The presence of the seashore sign on
M-mode rules out pneumothorax.
The correct answer is: presence of barcode sign

hyperventilation. Insensible water also increases when the

upper airway is bypassed
and no supplemental humidification is provided.
The correct answer is: bypassed upper airway
6. Which of the following would Common factors decreasing metabolic rate (and thus energy
decrease a patient's energy ex- expenditure) include
penditure? sedation/analgesics, muscle paralysis, shock/hypovolemia,
A. hypothermia hypothermia/cooling,
B. inflammation hypothyroidism, antipyretics, starvation, and properly applied
C. major trauma ventilatory support.
D. agitation/pain Conversely, fever, Inflammation (including SIRS), sepsis, ma-
jor trauma (including
burns), shivering, seizures, agitation/anxiety/pain, hyperthy-
roidism, adrenergic drugs
and ventilator weaning all tend to increase energy expendi-
ture.
The correct answer is: hypothermia

A. + 6 mEq/L response to a chronic respiratory acidosis, the base excess
B. - 6 mEq/L should rise above the
D. +/- 2 mEq/L normal range (due to the increased levels of HCO3).
E. +/- 8 mEq/L The correct answer is: +/- 2 mEq/L
