| how many phalanges in each hand? | 14 |
| how many carpal bones in each wrist? | 8 |
| proximal row of carpal bones starting at the lateral (thumb) side | scaphoid, lunate, triquetrum, pisiform |
| distal row of carpal bones starting at the lateral (thumb )side | trapezium, trapezoid, capitate, hamate |
| largest carpal bone | capitate |
| most frequently fractured carpal bone | scaphoid |
| bones of the forearm | radius and ulna |
| which forearm bone is the lateral | radius |
| which forearm bone is medial | ulna |
| which forearm bone is longer | ulna |
| radial head articulates with | capitulum of humerus |
| how many views of the forearm are there? | 2 PA and lateral |
| radiographic views of the hand | PA, oblique, lateral |
| when the hand is in the PA position, what position is the thumb in? | oblique |
| when the hand is in the lateral position, what position is the thumb in? | PA |
| what is the purpose of the oblique hand radiograph | visualize interphalangeal joints |
| what is the purpose of the ulnar deviation view of the wrist | visualization of the scaphoid |
| what are we looking for in a lateral wrist view? | displacement of the carpal bones |
| what is visualized in the external rotation of the elbow? | the radial head |
| when the arm is extended and the epicondyles are parallel to the film, and the CR is in the center of the antecubital fossa which radiographic view is this? | AP elbow |
| what is being visualized in the internal oblique view of the elbow | coronoid process |
| when is it appropriate to do the trans-thoracic Lawrence method of the shoulder? | trauma, when the patient cannot move their arm |
| what is being visualized in the AP humerus? | the greater tubercle |
| what are the structures shown on the lateral humerus? | lesser tubercle |
| AP neutral shoulder | hand pronated, palm against thigh. NO tubercles visualized |
| AP internal rotation shoulder | internal rotation of arm, back of hand against thigh, lesser tubercle visualized |
| AP external rotation shoulder | external rotation of arm, pinky touchin thigh, greater tubercle vizualized |
| AP scapula | elbow abducted and flexed at 90 degrees, CR mid scapula |
| lateral scapula | scapular Y on xray. patient positioned with arm behind back or across chest grabbing opposite shoulder |
| where is the CR for an AP clavicle? | mid clavicle |
| how many degrees do we angle the tube for an AP axial clavicle? | 15-30 degrees |
| what is the purpose of the AP axial clavicle view? | to project the clavicle above the ribs |
| AC joints; AP with and without weights, what's the purpose of this? | to show dislocation of the joint |

| which projection best demonstrates the patella and femoral articulation? | lateral view of the knee |
| which position of the elbow demonstrates the radial head without superimposition of the ulna? | external oblique elbow |
| what is necessary to take a decubitus xray | horizontal xray beam |
| what is the purpose of the decubitus xray | air / fluid levels |
| what is the degree of medial rotation of the ankle for the Mortise view | 15-20 degrees |
| when positioning the patient for a lateral elbow xray, describe the body position | elbow flexed to 90 degrees, armpit ON THE TABLE, thumb up |
| what structures are best demonstrated in the scapular Y xray | body of scapula with no superimposition by ribs, acromion or cocacoid. |
| the condition in which air enters the pleural cavity and the lung collapses | pneumothorax |
| sneezing or coughing is which type of disease transmission? | droplet |
