patient?
Order Obstetric Anesthesia Discussion
A. Increased dose requirement for the same level and duration of block
B. Slower onset of neuraxial blockade
C. Longer duration of neuraxial blockade
D. Decreased neural sensitivity to local anesthetics

4. Which of the following pharmacokinetic physiologic changes in drug metabolism
do you anticipate in a pregnant woman at term?
A. Decreased requirement of isoflurane for maintenance of general anesthesia
B. Slower increase in alveolar concentration of inhaled anesthetics due to increased
cardiac output
C. Increased susceptibility to propofol induction
D. Prolonged paralysis after succinylcholine administration
E. Increased dose requirements for aminosteroidal neuromuscular blockers (such as
vecuronium and rocuronium)
5. 5. During which time period of a normal pregnancy does the PaCO2 decrease to
reach a level of 30 mm Hg?
A. 8 weeks
B. 12 weeks
C. 20 weeks
D. 28 weeks
6. Which of the following changes in lung volume occurs in a pregnant patient at
term compared with prepregnancy?
A. Increased functional residual capacity (FRC)
B. Increased vital capacity
C. Decreased inspiratory capacity
D. Decreased expiratory reserve volume
E. Decreased inspiratory reserve volume
7. Which of the following renal physiologic adaptations is NOT commonly seen in
pregnancy?
A. Increased creatinine clearance
B. Increased glomerular filtration rate
C. Increased protein excretion
D. Decreased serum bicarbonate
E. Decreased glucose excretion
8. Which of the following statements is correct regarding biliary disease during
pregnancy?
A. Hormonal changes in pregnancy account for altered bile acid content.
B. Alkaline phosphatase (AP) levels increase during pregnancy because of biliary
stasis.
C. Intrahepatic cholestasis of pregnancy is a normal phenomenon that is not
associated with increased risk to the fetus.
D. Computerized tomography is the gold standard for diagnosis of gallstones in
pregnancy.
E. Laparoscopic surgery is significantly safer during pregnancy in reducing fetal
loss as compared with open cholecystectomy.
9. Which of the following statements regarding gastrointestinal (GI) changes
during pregnancy is true?
A. Gastroesophageal reflux disease is common, and lower esophageal sphincter
pressures are significantly reduced during the first trimester.
B. Gastric emptying becomes progressively more delayed during the later trimesters
of pregnancy.
C. Preoperative fasting guidelines for scheduled cesarean section required
increased fasting periods compared with other surgical procedures.
D. Intestinal transit and peristalsis are slowed during pregnancy, resulting in
constipation.
E. The use of nonparticulate antacids to increase gastric pH has demonstrated a
significant decrease in clinical aspiration events.
10. Which of the following statements regarding hematologic changes during
pregnancy is false?
A. Plasma volume increases more in pregnancy than red blood cell (RBC) volume,
resulting in a physiologic anemia of pregnancy.
B. There is increased fibrinolytic activity during pregnancy, resulting in elevated
fibrin degradation products.
C. Procoagulant proteins including factors I, VII, VIII, IX, and X are increased
during pregnancy, resulting in a prothrombotic state.
D. White blood cell function is impaired during pregnancy.
E. Platelet consumption during pregnancy is unchanged compared with that during
prepregnancy.
