The COMT exam has 190 questions and runs 3 hours.
These 10 free COMT questions are organized by exam domain, so you can see how each part of the Certified Ophthalmic Medical Technologist blueprint is tested. Reveal the answer and explanation under each question.
Neck extension and right rotation reproduce a patient's familiar pain from the lateral forearm into the thumb. Examination shows weak right wrist extension and a reduced brachioradialis reflex; finger abduction and the triceps reflex are preserved. Which localization best accounts for this combination?
Correct answer: C - Right C6 nerve-root dysfunction
An occupational therapist is reviewing upper-limb outcomes. The initial QuickDASH disability/symptom score was 55/100. At follow-up, 10 of the 11 main items are completed and total 26; all four optional work-module items are completed and total 16. The scoring formula is [(mean item score) - 1] x 25. Which entry correctly records the follow-up main score and its direction of change?
Correct answer: B - 40/100; lower reported disability than at baseline
Active shoulder elevation stops at 75 degrees because of lateral upper-arm pain, whereas passive elevation reaches 160 degrees and passive external rotation is nearly symmetric. Resisted abduction and external rotation reproduce the familiar pain. Symptoms developed gradually, without trauma; cervical movement, reflexes, and sensation are unremarkable. Which explanation best fits the movement loss?
Correct answer: B - Rotator-cuff-related pain limiting active elevation
A warehouse worker with three weeks of low-back and right leg pain is tested with repeated lumbar extension. Pain retreats from the lateral foot to the buttock, the repeat neurological screen remains normal, and walking becomes easier. A mild central back ache during the last repetitions settles shortly afterward. No red flags are identified. How should this response guide the initial plan?
Correct answer: D - Continue monitored extension and graded walking, with repeat assessment of distal symptoms and neurological function.
The left side of the pelvis drops during right single-leg stance. Further testing finds weakness of the right gluteus medius, gluteus minimus, and tensor fasciae latae, with preserved gluteus maximus strength. Which nerve and pelvic exit match the weak muscle group?
Correct answer: D - Superior gluteal nerve; above piriformis
After locating the second costal cartilage at the sternal angle, a clinician traces the next rib inferiorly to its posterior articulations. Which vertebral relationships identify this rib's head and tubercle?
Correct answer: C - Head: T2 and T3 bodies; tubercle: T3 transverse process
Two approaches to restricted talocrural dorsiflexion are being compared: a non-weight-bearing glide of the talus with the tibia stabilized, and a heel-down lunge in which the talus is stabilized while the tibia advances. In the sagittal-plane joint-surface model, which pair of accessory translations is consistent with these approaches, respectively?
Correct answer: A - Posterior talar glide; anterior tibial glide
A previously painful, stiff shoulder is now much less irritable. Passive external rotation meets a firm restriction before mild discomfort, and symptoms settle immediately after testing. The clinician applies small-amplitude oscillations into that restricted end range. How should the technique be documented in the Maitland system?
Correct answer: D - Grade IV mobilization
Intermittent median-distribution paresthesias are reproduced during neurodynamic testing and eased by releasing load at a remote joint. Strength and reflexes are unchanged, and the symptoms settle promptly. To promote neural excursion while limiting sustained strain, which movement strategy should begin the mobilization trial?
Correct answer: A - Load one end while slackening the other, then reverse the pairing.
Before planned cervical thrust manipulation, a patient reports sudden, unfamiliar occipital pain that began 30 minutes ago. During the interview, the patient develops double vision and cannot walk steadily. A previous visit documented a symptom-free extension-rotation positional test. What should happen now?
Correct answer: A - Activate emergency medical assessment for possible vascular pathology.
