Chapter 4: Strategies for Approaching Multiple-Choice Questions of the Examination

Identify the muscle responsible for elbow flexion and forearm supination.

A. Triceps

B. Supinator

C. Biceps brachii

D. Anconeus

E. Brachioradialis

Option C is correct, as the biceps brachii is the only muscle that performs elbow flexion and forearm supination. This question tests your ability to recall basic anatomic function.

Of the following joints, select the one that is proximal to the knee.

A. Subtalar

B. Calcaneocuboid

C. Tarsometatarsal

D. Hip

E. Tibiofibular

Option D is correct, as the hip is the only articulation above the knee. Note that some questions will test more than one type of knowledge. In this question, two skills are being tested: vocabulary, as the definition of proximal is needed, and anatomy, as knowledge of the location of each of these joints is required.

An athlete displays pain and weakness during flexion and supination of the forearm. Which of the following muscles would you predict was injured?

A. Triceps

B. Supinator

C. Coracobrachialis

D. Anconeus

E. Biceps brachii

Option E is correct, as you apply your knowledge of muscle actions to a given set of facts.

An athlete reports to the athletic training room following a shoulder injury with a marked decrease in right elbow flexion and forearm supination strength and paresthesia along the lateral and medial upper arm, elbow, and forearm. Which of the following nerves would you infer is involved?

A. Musculocutaneous

B. Axillary

C. Long thoracic

D. Median

E. Radial

This question requires that you recognize the muscle involved in the injury, the nerve that innervates it, and the nerve that supplies the dermatome. Therefore, the correct answer is option A, the musculocutaneous nerve.
