A 16 year-old boy fell from a motorcycle, and his radial nerve was severely damaged because of a fracture of the midshaft of the humerus. Which of the following conditions would most likely result from this accident?
A. Loss of wrist extension leading to wrist drop
B. Weakness in pronating the forearm
C. Sensory loss over the ventral aspect of the base of the thumb
D. Inability to oppose the thumb
E. Inability to abduct the fingers

A. Loss of wrist extension leading to wrist drop.

Explanation:

An injury to the radial nerve always results in loss of wrist extension, that usually leads to to wrist drop. This is because the median nerve innervates the pronator teres, pronator quadratus, and opponens pollicis muscles and also the skin over the ventral aspect of the thumb.

The ulnar nerve innervates the

dorsal interosseous muscles, which act to abduct the fingers.

So any injury at the radial nerves will make the it hard or impossible for the wrist to extend and it will make the wrist to drop.

low context culture   (lc.):

association:    

relationships begin and end quickly. many people can be inside one's circle; circle's boundary is not clear.

things get done by following procedures and paying attention to the goal.

one's identity is rooted in oneself and one's accomplishments.

social structure is decentralized; responsibility goes further down (is not concentrated at the top).

interaction:

low use of nonverbal elements. message is carried more by words than by nonverbal means.

verbal message is explicit. context is less important than words.

verbal message is direct; one spells things out exactly.

communication is seen as a way of exchanging information, ideas, and opinions.  

disagreement is depersonalized. one withdraws from conflict with another and gets on with the task. focus is on rational solutions, not personal ones. one can be explicit about another's bothersome behavior.

territoriality:

space is compartmentalized and privately owned; privacy is important, so people are farther apart.

temporality:

things are scheduled to be done at particular times, one thing at a time. what is important is that activity is done efficiently.

change is fast. one can make change and see immediate results.

time is a commodity to be spent or saved. one’s time is one’s own.

learning:

reality is fragmented and compartmentalized. one source of information is used to develop knowledge. thinking is inductive, proceeds from specific to general. focus is on detail.

learning occurs by following explicit directions and explanations of others.

an individual orientation is preferred for learning and problem solving.

speed is valued. how efficiently something is learned is important.
