After a ventilator patient's PEEP level is increased from 8 cm H2O
to 12 cm H2O, the PvO2 drops from 37 torr to 33 torr. This
indicates which of the following?
A. Venous return has increased
B. Tissue oxygenation has increased
C. Static CL has increased
D. QT has decreased - ANSWER-. D, A drop in mixed venous
PO2is indicative of a decreased QT. This drop in PvO2occurs
because the tissues extract O2from the blood at the same rate,
even though the blood is flowing slower past the tissues
(decreased QT). Therefore, more O2is extracted and by the time
the blood reaches the pulmonary artery, which is where PvO2is
measured, there is less O2is in the blood.
A patient's pulmonary function study shows an FRC of 127% of
predicted. The patient most likely has which of the following
conditions?
A. Pulmonary fibrosis
,2|Page
B. Atelectasis
C. Emphysema
D. Pneumonia - ANSWER-C, FRC is the amount of air remaining
in the lungs after a normal exhalation. Because patients with
emphysema trap air during exhalation, more air stays in the lungs
after exhalation and FRC increases.
A patient is breathing 16 times per minute and has a VT of 450
mL. What is this patient's minute ventilation?
A. 4.2 L
B. 6.1 L
C. 7.2 L
D. 8.6 L - ANSWER-C, Minute ventilation is calculated as follows:
VT×RR
Convert VT from milliliters to liters by dividing by 1000.
0.45×16 = 7.2 L
Which of the following is assessed to help diagnose CHF?
,3|Page
A. CPK
B. BNP
C. WBC
D. Troponin - ANSWER-B, B-type natriuetic peptide (BNP) is a
biomarker used to help diagnose congestive heart failure. BNP is
a cardiac neurohormone that is secreted in response to increased
ventricular blood volume and pressure caused by heart failure. A
level > 500 pg/mL indicates CHF.

diagnose congestive heart failure. BNP is a cardiac
neurohormone that is secreted in response to increased
ventricular blood volume and pressure caused by heart failure. A
level ___________ pg/mL indicates CHF - ANSWER-> 500
The reduction in urinary output caused by mechanical ventilation
may be the result of
A. Increased renal blood flow
B. Increased production of ADH
C. Decreased CVP
, 4|Page
D. Decreased airway resistance - ANSWER-B, Positive pressure
ventilation has the potential for decreasing venous blood return to
the heart. This results from this pressure being transferred to the
superior and inferior vena cavae, which restricts blood flow back
into the heart. Baroreceptors (pressure receptors) sense this
lower pressure in the right atrium and send signals to the brain,
which causes an increased production of ADH by the pituitary
gland. This causes the body to hold on to more fluid as a
compensatory mechanism because the right side of the heart is
sensing a low pressure. The decreased cardiac output results in
decreased perfusion to the kidneys, which can also reduce urine
output.
Which value indicates that a patient is most likely ready to be
weaned from mechanical ventilation?
A. VD/VT of 50%
B. MIP of 16
C. RSBI of 145
D. Spontaneous VT of 3 mL/kg - ANSWER-A, A VD/VT of less
than 0.60 indicates weaning should be attempted. For weaning to
