Review Questions, Answers & Clinical Prep University of Columbia
This study resource is built for airport workers, ground handlers, and
aviation professionals preparing for the YVR D/A AVOP Exam. It covers
the Airside Traffic Directives, including speed limits, right-of-way,
controlled areas, radio procedures, signage, and prohibited behaviors.
The unique MCQs include verified updated answers and detailed rationales
1. Which APRN is the exception to the graduate level preparation
requirement for certification for advanced practice registered
nurses?
A) Nurse Practitioner
B) Certified Registered Nurse Anesthetist (CRNA)
C) Clinical Nurse Specialist
D) Certified Nurse-Midwife
Explanation: The Certified Registered Nurse Anesthetist (CRNA) is the
exception because CRNAs may be prepared at the graduate level but are
also approved through a post-baccalaureate certificate pathway that has
historically been recognized differently. The other APRN roles require
graduate-level preparation.
2. A 72-year-old male with a history of hypertension and type 2
diabetes presents with a 3-day history of severe, tearing chest pain
,radiating to his back. His blood pressure is 180/100 mmHg in the
right arm and 140/80 mmHg in the left arm. Which of the following
is the most appropriate initial diagnostic test?
A) Transthoracic echocardiogram
B) Computed tomography angiography (CTA) of the chest
C) Electrocardiogram (ECG)
D) Chest X-ray
Explanation: The classic presentation of acute aortic dissection includes
severe tearing chest pain radiating to the back with a significant blood
pressure differential between arms. CTA of the chest is the gold standard
due to its high sensitivity and specificity.
3. A 55-year-old female presents with a 6-month history of
progressive fatigue, dyspnea on exertion, and a dry cough. Physical
examination reveals bilateral inspiratory crackles at the lung bases
and digital clubbing. High-resolution CT shows a reticular pattern
with honeycombing predominantly in the subpleural and basal
regions. Which of the following is the most likely underlying
diagnosis?
A) Sarcoidosis
B) Usual Interstitial Pneumonia (UIP)
C) Hypersensitivity Pneumonitis
D) Cryptogenic Organizing Pneumonia (COP)
,Explanation: The combination of progressive dyspnea, dry cough,
bibasilar crackles, and digital clubbing with HRCT findings of reticular
pattern and honeycombing in a subpleural and basal distribution is highly
characteristic of UIP, the pathologic pattern of Idiopathic Pulmonary
Fibrosis.
4. A 45-year-old male with a history of alcohol use disorder is
brought to the emergency department after a generalized tonic-
clonic seizure. His serum sodium is 110 mEq/L. Which of the
following is the most critical immediate step in management to
prevent osmotic demyelination syndrome?
A) Administer 3% hypertonic saline at 100 mL/hour
B) Restrict free water intake to 500 mL/day
C) Correct serum sodium by no more than 8-10 mEq/L in the first 24
hours
D) Administer intravenous furosemide to increase free water excretion
Explanation: Overly rapid correction of severe hyponatremia can
precipitate osmotic demyelination syndrome. The safe rate of sodium
correction is 8-10 mEq/L in 24 hours.
5. A 32-year-old female presents with a 3-day history of a red,
swollen, and painful right lower leg. The patient also reports feeling
, feverish. Upon examination, the skin is warm to the touch, and there
is localized erythema. What is the most likely diagnosis?
A) Deep Vein Thrombosis (DVT)
B) Cellulitis
C) Sprain
D) Gout
Explanation: Cellulitis is a bacterial skin infection often caused by
Streptococcus or Staphylococcus species, resulting in red, swollen, and
painful skin, sometimes accompanied by fever.
6. A patient has a history of asthma and presents to the clinic with
increased shortness of breath, wheezing, and a decreased peak flow
rate. The patient's pulse oximetry reading is 92%. Which of the
following is the most appropriate next step in management?
A) Administer oxygen and monitor the patient.
B) Administer a short-acting beta-agonist (SABA) inhaler.
C) Begin IV corticosteroids.
D) Initiate mechanical ventilation.
Explanation: In patients with asthma exacerbations, the first-line
treatment is a short-acting beta-agonist (e.g., albuterol) to relieve
bronchoconstriction. Administering oxygen or corticosteroids may be
appropriate later, but the immediate treatment is aimed at improving
airflow.
