Alveolar macrophages keep alveolar surfaces __? - ANSWER-
Sterile
A patient's arterial blood gas indicates that her PaCO2 in 55
mmHg. What can
you conclude about her ventilation state? - ANSWER-she is
hypoventilating
A post-op patient is still unconscious, but is receiving
supplemental oxygen via a mask device. An ABG indicates that
pH = 7.31, PaO2 = 155 mmHg, PaCO2 =
82 mmHg, HCO30 = 26 mEq/L. What is true? - ANSWER-Patient
is acidotic
HCO3- is normal
PaCO2 is elevated
,With respect to the pulmonary circulatory system overall
compliance of the
system is -
ANSWER-high
In the case of severe embolism, over time the gas comp of
alveoli will become -
ANSWER-150 mmHg O2; 0
mmHg CO2
Regarding pulmonary edema (PE), what is true? -
ANSWER-PE is
characterized by increased fluid in the
interstitial space
Oxygen therapy can be effective during early stage PE
PE is characterized by decreased Dl-
Decreased gas diffusion with PE
In late stage pulmonary edema, the ventilation to perfusion
(V/Q) ratio will -
ANSWER-
decrease
, In the Henderson-Hasselbalch equation, HCO3- is in the
___? - ANSWER-
Denominator
According to the Henderson-Hasselbalch equation, if PaCO2
decreases to 20
mmHg, then arterial pH will ___? -
ANSWER-Increase
74 yr old moderately dehydrated man was admitted with a two
day history of acute severe diarrhea. ABGs are as follows, pH =
7.31, PaCO2 = 33 mmHg,
PaO2 = 98 mmHg and HCO3- = 16 mM. The most likely
diagnosis is __? -
ANSWER-Metabolic acidosis with respiratory compensation
The respiratory center that controls inspiration is the __? -
ANSWER-dorsal
respiratory group
(DRG)
Within peripheral chemoreceptors, the response to a drop in
PaO2 is greater
when __? - ANSWER-Arterial PaCO2 is
above normal
