Which anatomy accepts the coronoid process with the arm in flexion?
olecranon fossa
coronoid fossa
capitulum
radial fossa
coronoid fossa
Rationale: The coronoid process is located on the proximal ulna. Between the coronoid process and the olecranon process exists the trochlear notch which pivots around the trochlea on the distal humerus. With flexion of the arm, the coronoid process will sit within the coronoid fossa which is superior to the trochlea on the anterior distal humerus.

Medial epicondylitis a) Inflammation in the common flexor tendon due to repetitive strain from activities requiring repetitive and ballistic elbow flexion, also called "golfer's elbow." b) Compression of the median nerve and tendons under the flexor retinaculum ligament, resulting in wrist inflammation and pain, numbness and tingling in the fingers, and weakness in the hand that manifests as the loss of grip strength. c) Inflammation in the common extensor tendon due to repetitive strain from activities requiring repetitive and ballistic elbow extension, also called "tennis elbow."

What is the purpose of the demand-valve resuscitator?
A. It senses whether a person is breathing on their own and sends a warning signal to start CPR when breathing has ceased. B. It regulates the pressure of the oxygen being released from the tank. C. It forces oxygen into the lungs of a person who is not breathing. D. It synchronizes with the flowmeter and adjusts the ratio of oxygen to carbon dioxide depending on the needs of the patient.
