Following a traumatic injury to the forearm, a patient exhibits weakened wrist flexion and adduction, alongside impaired sensation in the medial aspect of their hand. Which nerve is MOST likely affected?

A surgeon inadvertently ligates the common interosseous artery during a complex forearm reconstruction. What is the MOST immediate and significant risk to the patient's forearm?

A patient presents with an inability to extend their wrist and fingers, along with sensory loss on the posterior aspect of their forearm and dorsum of their hand. Where is the MOST likely location of the nerve lesion?

Which combination of motor deficits would MOST likely result from damage to the musculocutaneous nerve?

A patient can no longer oppose their thumb or make a fist properly. Sensation is diminished on the lateral palm. Which nerve is MOST likely compromised?

Following a deep laceration to the anterior forearm, a patient exhibits weakness in flexing the distal interphalangeal joints of the 4th and 5th digits. Which muscle is MOST likely affected?

A patient presents with paralysis of the deltoid and teres minor muscles following a shoulder injury. Which nerve is MOST likely damaged?

A patient is unable to extend the elbow against resistance, and also has diminished sensation on the posterior aspect of the forearm. Which nerve is MOST likely injured?

A patient has lost sensation in the lateral aspect of their forearm. Which nerve provides sensory innervation to this region?

In a patient with complete median nerve damage at the elbow, which motor function would remain MOSTLY intact?

Following a laceration on the anterior aspect of the forearm, a patient exhibits weakened flexion at the wrist and impaired abduction. Which nerve is LEAST likely to be injured?

A surgeon is performing a procedure near the elbow and needs to identify the nerve that innervates the pronator teres muscle. Which of the following is the correct nerve to identify?

A patient presents with an inability to extend the phalanges of the index finger and thumb. Which nerve is MOST likely affected, considering its deep posterior compartment innervation?

During a boxing match, a boxer sustains a direct blow to the anterior forearm, resulting in a compromised ability to flex the distal interphalangeal joints of the 2nd and 3rd digits. Sensation on the palmar aspect of these digits remains intact. Which structure has MOST likely been injured?

A patient is diagnosed with carpal tunnel syndrome, leading to compression of the median nerve. Which action would MOST likely remain unaffected, due to its exclusive innervation by a different nerve?

A patient reports difficulty in supinating their forearm. Electromyography reveals impairment of a muscle in the deep posterior compartment. Which of the following muscles is MOST likely affected?

Following a fracture of the radius near the radial tuberosity, a patient experiences weakness during flexion of the elbow when the forearm is supinated. Which muscle is MOST likely affected?

A patient has lost the ability to extend the 5th digit and adduct the hand at the wrist. Which single nerve injury would MOST likely cause these specific deficits?

A weightlifter strains their forearm while performing a bicep curl, and subsequently experiences pain and weakness during wrist flexion and tightening of the palmar aponeurosis. Which muscle is MOST likely injured?

A surgeon accidentally transects a nerve during a procedure to repair the ulna. Post-operatively, the patient cannot flex the distal interphalangeal joint of the 5th digit. Which nerve was MOST likely damaged?
