Question 1

Which of the following best defines axonotmesis?&#10;A) An injury in which nerve fibers distal to the site of injury degenerate but the internal organization of the nerve remains intact&#10;B) Contusion of the nerve without Wallerian degeneration&#10;C) Complete laceration of both nerve and fibrous tissues&#10;D) An injury in which surgical intervention is typically required

Accepted Answer

Axonotmesis is an injury in which nerve fibers distal to the site of injury degenerate but the internal organization of the nerve remains intact.No surgical intervention is necessary,and recovery usually occurs within 6 months.The length of time may vary depending on the level of injury.

Question 2

The volumeter is used to measure which of the following?&#10;A) Strength&#10;B) Girth&#10;C) Hand volume (edema)&#10;D) Sensation

Accepted Answer

Hand volume is measured to assess the presence of extracellular or intracellular edema.Volume measurement is generally used to determine the effect of intervention and activities.

Question 3

Name the test in which the examiner places pressure over the median nerve in the carpal tunnel for up to 30 seconds to see if this creates tingling in the median nerve distribution.&#10;A) Carpal compression test&#10;B) Reverse Phalen's test&#10;C) Test for Tinel's sign&#10;D) Roos test

Accepted Answer

In the carpal compression test,the examiner places pressure over the median nerve in the carpal tunnel for up to 30 seconds.The test result is positive if tingling occurs in the median nerve distribution.The combination of wrist flexion and compression of the median nerve for 20 seconds has been found to be more sensitive than other provocative tests used alone.

Question 4

Which of the following is the most common injury to the wrist?&#10;A) Colles' fracture&#10;B) Scaphoid fracture&#10;C) Lunate fracture&#10;D) Pisiform fracture

Accepted Answer

Wrist fractures are common and may present special problems for the surgeon and therapist.Colles' fractures of the distal radius are the most common injury to the wrist and may result in limitations in wrist flexion and extension,as well as pronation and supination,resulting from the involvement of the distal radioulnar joint.

Question 5

Positive Phalen's test is associated with which of the following?&#10;A) Cubital tunnel syndrome&#10;B) Radial tunnel syndrome&#10;C) Carpal tunnel syndrome&#10;D) Trigger finger

Accepted Answer

Phalen's test is performed by fully flexing the wrists with the dorsum of the hands pressing against each other.Reverse Phalen's is performed by holding the hands in the "prayer" position for 1 minute.The test results are positive if the client reports tingling in the median nerve distribution (thumb,index,middle,and radial aspect of ring finger)within 1 minute.

Question 6

Which of the options below is an accessory motion?&#10;A) Joint distraction&#10;B) Extension&#10;C) Flexion&#10;D) Abduction

Accepted Answer

Small,involuntary motions of the joint are called joint play or accessory motions.Both terms describe those movements that are involuntary and physiological and can be performed only by someone else.Examples of accessory motions are joint rotation and joint distraction.If accessory motions are limited and painful,the active motions of that joint cannot be normal.Therefore it is necessary to restore joint play through the use of joint mobilization techniques before attempting passive or active range of motion (ROM).

Question 7

One tool used to test two-point discrimination is __________.&#10;A) A vibrator&#10;B) Calipers&#10;C) Monofilaments&#10;D) The eraser end of a pencil

Accepted Answer

A variety of devices have been proposed for use in measuring two-point discrimination.The bent paper clip is inexpensive but often has burrs on the metal tip.Other devices include industrial calipers and the Disk-Criminator.A device with parallel prongs of variable distance and blunted ends should produce replicable results.

Question 8

Which nerve is called the &#34;eyes&#34; of the hands?&#10;A) Radial nerve&#10;B) Median nerve&#10;C) Ulnar nerve&#10;D) Posterior interosseous nerve

Accepted Answer

The median nerve innervates the flexors of the forearm and hand and is often called the "eyes" of the hands because of its importance in sensory innervation of the volar surface of the thumb,index,and middle fingers.Median nerve loss may result from lacerations,as well as from compression syndromes of the wrist,such as carpal tunnel syndrome.

Question 9

Skier's thumb is _____________.&#10;A) When the thumb locks in flexion&#10;B) When the thumb interphalangeal joint is hyperextended&#10;C) When the thumb web space is contracted&#10;D) Instability of the thumb MP ulnar collateral ligament

Accepted Answer

Skier's thumb,also called gamekeeper's thumb,is pain and instability of the thumb MP joint.Stressing the thumb proximal phalanx into radial deviation at the MP joint causes pain,and the injured thumb is more lax at the MP joint than the ipsilateral thumb.

Question 10

Extrinsic extensor tightness is demonstrated by which of the following?&#10;A) Decreased passive proximal interphalangeal (PIP) flexion when the metacarpophalangeal (MP) joint is extended&#10;B) Decreased passive PIP flexion when the MP joint is flexed&#10;C) Decreased PIP extension when the MP joint is extended&#10;D) Decreased PIP flexion when the MP joint is extended

Accepted Answer

To test for extrinsic extensor tightness,the MP joint is passively held in extension and the PIP joint is moved passively into flexion.Then the MP joint is flexed,and the PIP joint is again passively flexed.If the PIP joint can be flexed easily when the MP joint is extended but not when the MP joint is flexed,the extrinsic extensors are adherent.

Question 11

Asking the client to oppose the thumb to the fingers and flex the fingers is a quick test for which nerve?&#10;A) Radial&#10;B) Ulnar&#10;C) Posterior interosseous&#10;D) Median

Accepted Answer

The answer of Asking the client to oppose the thumb...

Question 12

Which of the following is not a sympathetic response?&#10;A) Sweating&#10;B) Gooseflesh&#10;C) Trophic changes (skin texture, nail and hair growth)&#10;D) Tendon adherence

Accepted Answer

Which digit is the most important to the hand?&#10;A) Thumb&#10;B) Index finger&#10;C) Long finger&#10;D) Ring finger

Accepted Answer

The answer of Which digit is the most important to...

Question 14

Sensibility testing is performed for all but one answer below.Pick the one that is not correct.&#10;A) To assess the recovery of a nerve following laceration and repair&#10;B) To assess mobility of a joint&#10;C) To determine the presence of a nerve compression syndrome and the return of nerve function after surgical decompression&#10;D) To determine the efficacy of conservative intervention to reduce compression

Accepted Answer

The answer of Sensibility testing is performed for all but...

Question 15

Which nerve innervates the extensor-supinator group of muscles of the forearm?&#10;A) Median nerve&#10;B) Radial nerve&#10;C) Ulnar nerve&#10;D) Anterior interosseous nerve
