What are the three most common used pharmacological agents for treating
ischemic heart disease? Correct Answer: Nitrates, beta-blockers, and calcium
channel blockers are the most commonly used pharmacological agents for
treating ischemic heart disease.
A patient with mitral stenosis is asymptomatic with occasional mild symptoms
with exertion. Which mitral valve area is associated with these symptoms?
Correct Answer: Patients with valve areas between 1.5 and 2.0 cm2 are usually
asymptomatic or have only mild symptoms with exertion. Critical mitral stenosis is
associated with valve are 0.5-1.0 cm2 or less. Mitral stenosis is usually diagnosed
when the valve area is 1.5 cm2 or less.
What is the onset of analgesia following administration of epidural morphine 5
mg? Correct Answer: The onset of epidural morphine is 30 to 60 minutes. The
duration of analgesia is 12 to 24 hours. Larger doses of epidural morphine are
needed for analgesia. However, delayed respiratory depression may result.
Which variable increases Minimum Alveolar Concentration (MAC)? Correct
Answer: Hypernatremia increases MAC
,You administered meperidine IV. Immediately following administration the
patient developed profound hypotension, hyperpyrexia and respiratory arrest.
You expect an interaction with: Correct Answer: Patients receiving MAO
inhibitors should not receive meperidine. In addition to hypotension,
hypertension, hyperpyrexia, and respiratory arrest, coma may result. Interaction
of alfentanil and erythromycin may lead to respiratory depression and
prolonged somnolence. Meperidine and other narcotics combined with central
nervous system depressants foster synergism that affects the respiratory and
cardiac systems.
Which agent results in an increased heart rate during inhalational anesthesia?
Correct Answer: Heart rate increases linearly with dose. There is a minimal
increase in heart rate with desflurane when using less than 1 MAC. The heart
rate increases with Sevoflurane at 1.5 MAC or greater.
Which local anesthetic is metabolized by 0-toluidine? Correct Answer: Prilocaine
Prilocaine is the only amide local anesthetic not metabolized by P-450
microsomal enzymes. Ester local anesthetics nesacaine is metabolized by
pseudocholinesterase whereas N-methylation and ester hydrolysis is responsible
for cocaine metabolism. Mepivacaine is metabolized by P-450 microsomal
enzymes.
Which local anesthetic is linked to methemoglobinemia? Correct Answer:
Methemoglobinemia is caused by prilocaine's metabolic pathway that includes
o-toluidine
what is the dose range for cocaine? Correct Answer: 1.5-3mg/kg
Which risk factor contributes to myocardial ischemia in a patient with aortic
regurgitation? Correct Answer: One anesthetic goal of managing a patient with
, aortic regurgitation is to maintain the heart rate toward the upper limits of
normal (i.e., c. 80 to 100 beats/minute). A heart rate that is too slow or an
increase in systemic vascular resistance will increase the regurgitant volume (A
and B). Tachycardia, on the other hand, will contribute to myocardial ischemia
in a patient with aortic regurgitation.
Where is the primary location of hepatic microsomal enzymes? Correct Answer:
The primary location of hepatic microsomal enzyme activity is the hepatic
smooth endoplasmic reticulum. Microsomal enzymes are also located in the
kidneys and gastrointestinal system to a lesser extent. The majority of reactions in
the small intestine involve P450 enzymes
In which valvular disease is the pulmonary capillary wedge pressure (PCWP) an
overestimation of the left ventricular end-diastolic pressure (LVEDP)? Correct
Answer: Mitral stenosis
Because of the abnormal transvalvular gradient in mitral stenosis, the PCWP
overestimates the LVEDP.
Which hemodynamic event will decrease coronary perfusion pressure the most?
Correct Answer: Coronary perfusion pressure = arterial diastolic pressure minus
the LVEDP. Any decreases in aortic pressure or increases in ventricular end-
diastolic pressure will reduce coronary perfusion pressure. Since PCWP is an
indirect measure of LVEDP, an increase in PCWP will decrease coronary
perfusion pressure.
What is the maximum allowable current leakage in the operating room? Correct
Answer: The maximum allowable current leak in the operating room is 10 uA.
What monitor alarms when a high current flow to the ground exists? Correct
Answer: The line isolation monitor affords protection from electrical shocks in the
