Questions & Detailed Rationales
QUESTION 1
A patient with Guillain-Barré syndrome has a vital capacity of 625 mL.
An RT should recommend which of the following be performed FIRST?
A) MIP evaluation
B) Edrophonium Chloride (Tensilon) test
C) MVV test
D) EMG and nerve conduction study
Correct Answer: A
Rationale: In Guillain-Barré syndrome, respiratory muscle weakness is a
primary concern. A vital capacity of 625 mL indicates significant
respiratory compromise. The first assessment should be MIP (Maximum
Inspiratory Pressure) evaluation to assess respiratory muscle strength.
The Tensilon test is used for myasthenia gravis, not GBS. MVV is too
exhausting for a patient with significant weakness. EMG and nerve
,conduction studies are diagnostic for GBS but do not assess immediate
ventilatory status.
QUESTION 2
A patient in the ICU complains of light headedness, nausea, and chest
pains. The patient is diaphoretic and has a blood pressure of 90/60
mmHg. What should the RT recommend?
A) Lidocaine HCl
B) Cardioversion
C) Defibrillation
D) Epinephrine
Correct Answer: B
Rationale: The patient is exhibiting signs of unstable tachycardia with
symptoms of hypoperfusion (lightheadedness, nausea, chest pain,
diaphoresis, hypotension). According to ACLS guidelines, unstable
tachycardia with a pulse requires synchronized cardioversion.
Defibrillation is used for ventricular fibrillation or pulseless ventricular
tachycardia. Lidocaine is an antiarrhythmic used for stable ventricular
arrhythmias. Epinephrine is used in cardiac arrest.
, QUESTION 3
A patient's sputum is purulent, green in appearance, has separated
into layers, and has a foul odor. What is the most likely cause?
A) Aspiration
B) Tuberculosis
C) Emphysema
D) Bronchiectasis
Correct Answer: D
Rationale: The sputum characteristics described—purulent, green,
layered, and foul-smelling—are classic for bronchiectasis. The layering
occurs due to the mixture of mucus, pus, and debris. The foul odor is
due to anaerobic bacteria. Aspiration pneumonia may have foul-
smelling sputum but is not typically layered. Tuberculosis sputum is
typically bloody. Emphysema does not typically produce purulent
sputum.
QUESTION 4
Which of the following bedside pulmonary function testing results for
a patient with multiple sclerosis most strongly indicates the need for
ventilatory assistance?
