COMSAE Comprehensive Exam BUNDLE - All Phases
2026/2027 | Questions & 100% Correct Verified
Answers | Grade A | Medical Board Prep
COMSAE PHASE 1 – COMPREHENSIVE BASIC SCIENCE (100 Qs)
Section 1 – Anatomy & OPP (30 Qs)
Q1
A 45-year-old male has epigastric pain that improves with food and worsens at night.
Tenderness and tissue-texture change are present at T5–T9 left paraspinals. This
viscerosomatic reflex is most consistent with pathology in which organ?
A. Heart
B. Liver
C. Stomach
D. Pancreas
Correct: C
Rationale: Gastric/peptic disease refers to T5–T9 left; cardiac = T1–T4, hepatic =
T5–T6 right, pancreas = T5–T9 often bilateral.
Q2
,A 30-year-old woman 20 weeks pregnant has low-back pain. Physical exam shows
anterior innominate rotation on the left. Which muscle’s hypertonicity most likely
maintains this dysfunction?
A. Left iliopsoas
B. Right piriformis
C. Left quadratus lumborum
D. Right gluteus maximus
Correct: A
Rationale: Iliopsoas attaches to lesser trochanter → anteriorly rotates innominate when
hypertonic.
Q3
A 50-year-old man with chronic ankle instability shows increased hind-foot valgus and
forefoot abduction on weight-bearing. Which ligament’s failure produces this talar tilt
pattern?
A. Calcaneofibular ligament
B. Anterior talofibular ligament
C. Deltoid ligament
D. Posterior talofibular ligament
Correct: C
,Rationale: Deltoid (medial) failure allows hind-foot valgus and forefoot abduction; lateral
ligament failure produces varus.
Q4
During cranial OMT, the physician notes sphenobasilar extension with external rotation
of the sphenoid. This is most consistent with which cranial strain pattern?
A. SBS compression
B. Torsion
C. Side-bending rotation
D. SBS extension
Correct: D
Rationale: Sphenobasilar extension = sphenoid rotates externally; mnemonic “extend =
external.”
Q5
A 25-year-old weight-lifter has deep shoulder pain when bench-pressing. Resisted
supination with elbow flexed produces pain. Which structure is most likely injured?
A. Supraspinatus tendon
B. Biceps brachii long-head tendon
C. Subscapularis
D. Coracobrachialis
, Correct: B
Rationale: Resisted elbow-flex + supination stresses biceps long-head tendon as it exits
bicipital groove.
Q6
A 60-year-old man with chronic cough has dullness to percussion and decreased
fremitus at the right lung base. Which viscerosomatic reflex level corresponds to
lower-lobe pneumonia?
A. T2–T4
B. T3–T5
C. T9–T11
D. T4–T7
Correct: C
Rationale: Lower-lobe pleura refers to T9–T11; upper lobe = T2–T4/5.
Q7
A 40-year-old man with chronic right shoulder abduction weakness shows winging of
the scapula with arms elevated. Which nerve root is most likely involved?
A. C5
B. C7
C. C8
