The diameter index safety system (DISS) is a national
standard that that ensures that the correct:
A) gas hose enters the machine from the wall connection -
Answer-DISS ensures that the correct pipeline gas enters
the correct part of the anesthesia machine. Blue is nitrous
oxide, green is oxygen, yellow is room air, white is the
hospital vacuum, and purple is the waste gas scavenging
vacuum.
In preparation for a fiberoptic nasal intubation, which
pharmacological agent would provide local anesthesia as
well as vasoconstrictive properties?
A) Cetacaine
B) Cocaine
C) Lidocaine
D) Phenylephrine - Answer-B) cocaine

In preparation for a fiberoptic nasal intubation, which
pharmacological agent would provide local anesthesia as
well as vasoconstrictive properties?
B) Cocaine - Answer-Cocaine is the only pharmacological
agent listed that provides both local anesthesia and
vasoconstrictive properties
Following induction of general anesthesia with IV propofol,
lidocaine, fentanyl, and succinylcholine, rigidity of the
masseter muscle is noted. The end-tidal carbon dioxide
sharply rises from 35 mmHg to 65 mmHg with adequate
tidal volumes. Tachycardia and peripheral muscle rigidity
were also noted. Which pharmacological agents would be
most appropriate to administer ? (select 2)
A) Bicarbonate
B) Dantrolene
C) Diltiazem
D) Rocuronium - Answer-A) Bicarbonate
B) Dantrolene

sharply rises from 35 mmHg to 65 mmHg with adequate
tidal volumes. Tachycardia and peripheral muscle rigidity
were also noted. Which pharmacological agents would be
most appropriate to administer ? (select 2)
A) Bicarbonate
B) Dantrolene - Answer-Administering Dantrolene is the
protocol when malignant hyperthermia (MH) is present.
Diltiazem is contraindicated with Dantrolene. Bicarbonate
is used to treat respiratory acidosis. Rocuronium has no
indication for use with MH.
Critical preoperative laboratory tests for a patient in end-
stage renal disease include: (Select 2) - Answer-Answers:
C, D
Rationale: Serum creatinine level reflects trends in renal
filtration and is the most commonly used renal test
available. Hyperkalemia is present in end-stage renal
disease.
During surgery for a laparoscopic fundoplication, the
patient becomes hypoxic and hypotensive upon
insufflation. What should be the first course of action?
A: administer ephedrine
B: Administer rocuronium

C: Remove the pneumoperitoneum
D: With draw the ETT - Answer-Answer: C, Remove the
pneumoperitoneum
The signs demonstrate a restrictive lung issue related to
the increased peak inspiratory pressure. The likely cause
is carbon dioxide tracking around the aortic, caval, and
esophageal hiatuses. If it were an improperly placed
endotracheal tube, such as a mainstem intubation, the
ETCO2 would be expected to decrease. The hypotension
would be a result of decreased preload, so ephedrine
would not be of benefit. Administration of paralytics would
not treat the cause.
The effects of carcinoid syndrome are related to the
release of?
A) choline acetyltransferase
B) histamine
C) parathyroid hormone
D) serotonin - Answer-Answers: B, D
Rationale: Carcinoid tumors are most often in the
gastrointestinal tract. Carcinoid tumors produce carcinoid
syndrome if the tumor's secretory substances do not first
drain into the hepatic system. The unmetabolized
secretions include serotonin, histamine, kinins,
