A 61-year-old woman underwent surgery to remove an ovarian cancer. Anesthesia was
induced by thiopental and maintained by sevoflurane and tubocurarine. After surgery the
anesthesiologist administered a drug to overcome the residual muscle relaxant effect fo
tubocurarine. Which of the following drugs was most likely given?
A. 
B. 
C. 
D. 
E. 
F. 
6.
A 67-year-old woman required intubation and mechanical ventilation for management
of respiratory failure. Tubocurarine was given IV to reduce chest wall resistance and
ineffective spontaneous ventilation. Which of the following membrane potentials was
most likely blocked by tubocurarine in this patient?
A. 
Action potential of motor nerve
B. 
Miniature end plate potential
C. 
Resting potential of smooth muscle
D. 
Action potential of cardiac muscle
E. 
Action potential of corticospinal tract
7.
A 65-year-old woman underwent hysterectomy to remove a uterine carcinoma. The
anesthesiologist chose thiopental sodium for induction and isoflurane and tubocurarine
for maintenance of general anesthesia. The anesthesiologist also administered another
drug in order to counteract tubocurarine induced hypotension. A drug belonging to which
of the following classes was most likely given?
A. 
B. 
C. 
D. 
E.

A 66-year-old woman was brought to the Emergency Room following a car accident. A
surgical operation was needed to repair a badly damaged leg. The woman was currently
receiving gentamicin and tolterodine for an urinary tract infection, timolol and latanoprost
for glaucoma, and lovastatin for hypercholesterolemia. The anesthesiologist chose
thiopental sodium for induction and isoflurane plus tubocurarine for maintenance of
general anesthesia. Which of the following patient’s medications most likely enhanced
the action of tubocurarine?
A. 
B. 
C. 
D. 
E. 
9.
A 73-year-old man underwent thoracic surgery to remove a lung cancer. General
anesthesia was supplemented with tubocurarine. Which of the following molecular
actions most likely mediated the muscle relaxant effect of this drug?

Stimulation of plasma cholinesterase
B. 
Long lasting activation of postsynaptic Nm receptors
C. 
Competitive blockade of postsynaptic Nm receptors
D. 
Blockade of action potential of the motor nerves
E. 
Blockade of Ca++ release from sarcoplasmic reticulum

A 38-year-old patient was admitted to the emergency room with extensive soft-tissue
burns. He was semiconscious and was artificially ventilated. His uncoordinated
respiratory movements were interfering with the mechanical ventilation. Which of the
following drugs was most likely administered to decrease the patient’s spontaneous
breathing?
A. 
B. 
C. 
D. 
E. 
F.

A 49-year-old woman required intubation and mechanical ventilation for management
of respiratory failure resulting from severe emphysema. The patient was agitated,
attempting to sit up in bed and reach for his endotracheal tube. Lorazepam was give IV
for sedation and the patient got drowsy but motor restlessness was only marginally
improved. A muscle relaxant was given IV. The patient relaxed as paralysis developed but
5 minutes later her heart rate was 160 bpm. Which of the following drugs most likely
caused this adverse effect?
A. 
B. 
C. 
D. 
E. 
12.

A. 
B. 
C. 
D. 
E.

started on a high dose of haloperidol. After 2 days of therapy she became rigid, appeared
confused at times and had a fever of 104° F. The physical examination revealed
tachycardia, labile blood pressure, profuse diaphoresis, sialorrhea, dyspnea and urinary
incontinence. Which of the following drugs was most likely given immediately to the
patient?
