The onset of a phase 1 NMB is preceded by
A) double burst fade
B) fasciculation's
C) posttetanic twitch
D) TOF ratio <0.6

, Answer: B
Rationale: When succinylcholine (Anectine) is administered, the muscle
response is a depolarizing block. A depolarizing block is also called a
phase I block, and fasciculations are seen.
A 70kg pt is having a left lung partial lobectomy for lung cancer. He consents for GA
with the addition of a left intercostal nerve block for post op pain. What is the
maximum dose of 2% lidocaine with epi for this patients block?
Give this one a try later!
Answer: D
Rationale: Local anesthetic toxicity usually occurs from an inadvertently
large amount of drug being administered into the IV system. It can also
occur from a large amount of drug absorption from a nerve block
administration. The maximum dose of lidocaine with epinephrine is
recommended at 7 mg/kg: 7 mg × 70 kg = 490 mg.
Which classification of drug is frequently used in combination with beta2-agonists in
the treatment of asthma?
A) Inhaled corticosteroids
B) IV cholinergic antagonists
C) Mast cell stabilizers
D) Methylxanthines
Give this one a try later!
, Answer: A
Rationale: In asthma, inhaled corticosteroids are used in combination with
long-acting beta2-agonists. Cholinergic antagonists are not popular due to
their side effects. Methylxanthines and mast cell stabilizers are not first-line
choices.
Which is the major mineralcorticoid produced in the adrenal cortex?
Give this one a try later!
Answer: A
Rationale: Aldosterone is the principal mineralcorticoid secreted by the
adrenal cortex. It is involved in volume regulation within the body. Its effect
on the kidney allows for sodium reabsorption in exchange for potassium or
hydrogen ion excretion. The 2 major control mechanisms for aldosterone
release are angiotensin II and serum potassium level. An understanding of
aldosterone is necessary in relation to fluid management of patients and
also in the impact it has on the kidneys.
Stimulation of which sensory nerve may trigger a laryngospasm?
A) Glossopharyngeal
B) Hypoglossal
C) RLN
D) SLN

Answer: D
Rationale: A laryngospasm is initiated by stimulation of the superior
laryngeal nerve.
