- BTriangle of auscultation
- CInguinal triangle

2During a triathalon biking accident, a rider fell and landed with the handle bar of her bike forced upward into her right axilla. Subsequently while swimming in another triathalon event she found that her right arm tired so badly during the swimming portion that she could barely finish the event. During examination it was found that movements involving adduction, medial rotation and extension of her arm were particularly weak and affected her swimming stroke. The nerve injured was the [blank_start]thoracodorsal nerve[blank_end]
- Athoracodorsal nerve
3After a penetrating wound in the area of the posterior axillary fold a patient had weakness in extension and adduction of the arm. Which muscle is likely involved? [blank_start]Latissimus Dorsi[blank_end]
- ALatissimus Dorsi
4While wandering around in the dark in an unfamiliar home, a visitor accidentally walks into a plate glass door. The door shatters and a shard of glass severs the posterolateral aspect of the woman's neck. Examination reveals that the she is unable to elevate the tip of her shoulder on the injured side. The nerve injured the [blank_start]accessory nerve[blank_end]
- Aaccessory nerve
5A person receives a laceration along the anterior border of the trapezius muscle in the neck and subsequently the point of his shoulder (scapula) sags and he has some difficulty fully abducting his arm. What nerve appears to have been severed? The [blank_start]Accessory Nerve[blank_end]
- AAccessory Nerve
6A 33-year-old woman underwent partial thyroidectomy for hyperthyroidism in which the thyroid failed to take radioactive iodine. She is noted to have some hoarseness of voice 1 month later. Which of the following is the more likely explanation?

- BInjury to the cricoid cartilage
- CInjury to the thyroid cartilage
- DInjury to the recurrent laryngeal nerve
7A 15-year-old boy is eating a fish dinner and inadvertently has a bone ”caught in his throat." He complains of significant pain above the vocal cords. Which of the following nerves is responsible for carrying the sensation for this pain?
- ASuperior laryngeal nerve
- BRecurrent laryngeal nerve
- CSpinal accessory nerve
- DHypoglossal nerve
8A 25-year-old woman underwent surgery for a thyroid nodule. Two months later, she complains of dryness of skin and muscle spasms.
Which of the following is the most likely explanation?- ALow serum magnesium
- BLow serum calcium
- CLow serum potassium
- DLow serum sodium
- ELow serum glucose
9A 54-year-old woman has undergone partial thyroid resection due to a nontender cold nodule that likely represents cancer. One week after surgery, she complains of twitching of the right arm and "spasms" of both hands. Which of the following is the most likely explanation?
- AAnxiety after surgery
- BEffects of anesthesia
- CParathyroid glands removed
- DVagal nerve injury
10A 2-year-old girl is diagnosed with torticollis involving the right (sternocleidomastoid m.) SCM.

- BHead rotated to the right
- CHead rotated to the left
- DHead extended in the midline plane

- AWeakness of the masseter muscle
- BDecreased sensation of the ipsilateral face
- CDecreased tearing from the ipsilateral eye
- DWeakness of the trapezius muscle
12A clinician is palpating the anterior neck of a patient who has been involved in a motor vehicle accident and notes the laryngeal prominence.
Which of the following describes the anatomical structure that corresponds to this prominence?- AThyroid cartilage
- BCricoid cartilage
- CHyoid bone
- DFirst tracheal ring
13A 45-year-old woman is undergoing thyroid surgery for suspected thyroid cancer. The surgeon has taken a midline approach and encounters significant bleeding below the isthmus of the thyroid gland. Which of the following is the likely cause of the bleeding?
- APenetration into the trachea
- BSuperior thyroid artery
- CInferior thyroid artery
- DThyroid ima artery
- EInferior laryngeal artery
14An emergency cricothyroidotomy is thought to be warranted due to airway collapse and severe laryngoedema. Which of the following is the most accurate description of the location of the cricothyroid membrane?
- AImmediately superior to the thyroid cartilage
- BImmediately inferior to the thyroid cartilage
- Clmmediately inferior to the cricoid cartilage
- DJust deep to the isthmus of the thyroid gland
- EImmediately inferior to the hyoid bone

- AExternal branch of the superior pharyngeal
- BHypoglossal
- CInternal branch of the superior laryngeal
- DLingual
- ERecurrent laryngeal
16In the process of doing an axillary lymph node dissection in a 50 year-old patient, the surgery resident cleans the space between the pectoralis major and minor muscles, in an attempt to remove all of the lateral pectoral lymph nodes. Upon recovery it is noted that the patient‘s lower pectoralis major is paralyzed. The nerve most likely injured is the [blank_start]Medial Pectoral Nerve[blank_end]
- AMedial Pectoral Nerve
17Postoperative examination revealed that the medial border and inferior angle of the left scapula became unusually prominent (projected posteriorly) when the arm was carried forward in the sagittal plane, especially if the patient pushed with outstretched arm against heavy resistance (e.g., a wall). What muscle must have been denervated during the axillary dissection?
[blank_start]Serratus Anterior[blank_end]- ASerratus Anterior
