Core Content Domains
Based on the NBCRNA content outline, the exam covers four core knowledge
domains :
Domain Approximate Percentage
Airway Management 34%
Applied Clinical Pharmacology 24%
Applied Physiology and Pathophysiology 24%
Anesthesia Equipment, Technology, and Safety 18%
SECTION 1: AIRWAY MANAGEMENT (Questions 1-25)
,Question 1
A patient with TMJ ankylosis, asbestosis, and tonsillar hypertrophy would present
the greatest difficulty for placement of which airway device?
A. Endotracheal tube
B. Laryngeal mask airway (LMA)
C. Oral pharyngeal airway
D. Nasal pharyngeal airway
Answer: B. Laryngeal mask airway (LMA)
Rationale: Supraglottic airway devices such as the LMA require adequate mouth
opening and proper pharyngeal anatomy for placement . TMJ ankylosis limits mouth
opening, tonsillar hypertrophy can obstruct the supraglottic space, and asbestosis-
related changes may affect positioning. These conditions create significant
challenges for LMA placement but may not preclude endotracheal intubation.
Question 2
What is the recommended anesthetic technique for a patient undergoing surgery
with somatosensory evoked potential (SSEP) monitoring?
A. Inhalational anesthesia with sevoflurane
B. TIVA using propofol and opioids
C. Nitrous oxide with muscle relaxants
D. Ketamine-based anesthesia
Answer: B. TIVA using propofol and opioids
Rationale: Total intravenous anesthesia (TIVA) with propofol and opioids is
recommended for SSEP monitoring because it causes less interference with
,evoked potentials . Inhalational agents and nitrous oxide significantly depress SSEP
signal amplitude and should be avoided.
Question 3
Which of the following agents significantly depresses SSEP amplitude and should
be avoided when SSEP monitoring is used?
A. Propofol
B. Fentanyl
C. Nitric oxide (NO)
D. Ketamine
Answer: C. Nitric oxide (NO)
Rationale: Nitric oxide significantly depresses SSEP signal amplitude, which is why
it should be avoided when SSEP monitoring is used . This effect is particularly
problematic because it can mask clinically significant changes in neural pathway
integrity during surgery.
Question 4
A patient presents with a history of difficult intubation. Which anatomical feature is
most predictive of difficult mask ventilation?
A. Large tongue
B. Receding chin
C. Obstructive sleep apnea
D. Obesity
, Answer: A. Large tongue
Rationale: Macroglossia (large tongue) is the most important predictor of difficult
mask ventilation. Other predictors include obesity, history of snoring, and lack of
teeth. The tongue can obstruct the airway during mask ventilation by falling back
against the posterior pharyngeal wall.
Question 5
Spinal nerves exit the spinal column by way of which anatomical structure?
A. Vertebral foramen
B. Intervertebral foramen
C. Neural foramen
D. Transverse foramen
Answer: B. Intervertebral foramen
Rationale: Spinal nerves exit the spinal column through the intervertebral foramen,
which is formed by the superior and inferior vertebral notches of adjacent
vertebrae . This is a critical anatomical consideration for regional anesthesia
techniques.
Question 6
The most common complication of endotracheal intubation is:
A. Esophageal intubation
B. Dental trauma
