DO Doctor of Osteopathic Medicine MCQ 5

Question 1

An osteopathic physician evaluates a patient post-operatively and notes restricted motion of the thoracic inlet. Which of the following structures passes through the thoracic inlet and is most affected by fascial restrictions in this area?

Accepted Answer

Vagus nerve, esophagus, trachea, subclavian vessels, and thoracic duct

Answer

The thoracic inlet is traversed by the vagus nerve, esophagus, trachea, subclavian arteries and veins, thoracic duct, brachial plexus, and other structures — fascial restriction here can impair multiple systems simultaneously.

Question 2

In the TART mnemonic used for somatic dysfunction diagnosis, what does the 'A' represent?

Accepted Answer

Asymmetry of bony landmarks or tissue texture

Answer

TART stands for Tissue texture changes, Asymmetry of position, Restriction of motion, and Tenderness — the four cardinal signs used to identify and document somatic dysfunction.

Question 3

A 25-year-old presents with recurrent headaches originating at the occiput. The physician finds restriction of the occipito-atlantal (OA) joint in extension. Using muscle energy technique, the patient should actively:

Accepted Answer

Flex the head while the physician prevents motion, then the physician moves into extension

Answer

For an OA restriction in extension, muscle energy positions the joint in flexion (toward the barrier), has the patient resist into extension (isometric contraction), then after relaxation, the physician moves further into flexion to gain range.

Question 4

Which of the following best describes the role of the dura mater in the primary respiratory mechanism (PRM) according to osteopathic cranial concept?

Accepted Answer

The reciprocal tension membrane (dura) transmits and balances fluctuations in CSF motion between cranium and sacrum

Answer

In cranial osteopathy, the dural membrane system — including the falx cerebri, tentorium cerebelli, and spinal dura — acts as a reciprocal tension membrane that transmits motion of the primary respiratory mechanism from the cranium to the sacrum.

Question 5

A physician diagnoses a patient with a 'sprung rib' (rib 6 on the left). Inhalation is restricted. The rib is held in exhalation position. Correct muscle energy treatment involves:

Accepted Answer

Patient inhales against physician resistance; physician repositions rib superiorly after each breath

Answer

For an inhalation-restricted rib (held in exhalation), muscle energy has the patient inhale (engaging inhalation musculature) against the physician's resistance, and after relaxation the physician repositions the rib upward toward inhalation.
