MULTIPLE CHOICE

 

1. What type of fracture occurs at a site of a preexisting bone abnormality and is a result of a force that would not normally cause a fracture?

a.	Idiopathic	c.	Pathologic
b.	Incomplete	d.	Greenstick

 

 

ANS:  C

Only a pathologic fracture is a break at the site of a preexisting abnormality, usually by force that would not fracture a normal bone.

2. Which type of fracture usually occurs in an individual who engages in a new activity that is strenuous and repetitive?

a.	Stress	c.	Insufficiency
b.	Greenstick	d.	Pathologic

 

 

ANS:  A

Only a stress fracture occurs in normal or abnormal bone that is subjected to repeated stress, such as repetitive and strenuous activities that occur during athletics.

3. Which term is used to identify the temporary displacement of two bones causing the bone surfaces to partially lose contact?

a.	Dislocation	c.	Malunion
b.	Subluxation	d.	Nonunion

 

 

ANS:  B

Dislocation is the temporary displacement of a bone from its normal position in a joint. If the contact between the two surfaces is only partially lost, then the injury is referred to as a subluxation. This selection is the only option that identifies the temporary displacement of two bones, causing the bone surfaces to partially lose contact.

4. Improper reduction or immobilization of a fractured femur can result in which outcome after cast removal?

a.	The muscles around the fracture site are weak.
b.	The fracture requires 6 to 8 weeks of physical therapy.
c.	The skin under the cast is dry and flaky.
d.	The bone is not straight.

 

 

ANS:  D

Improper reduction or immobilization of a fractured bone may result in nonunion, delayed union, or malunion. Malunion is the healing of a bone in a nonanatomic position that could result in the bone not being straight. The other options are not outcomes of improper reduction or immobilization.

5. Which structure attaches skeletal muscle to bone?

a.	Tendon	c.	Bursa
b.	Ligament	d.	Mesentery

 

 

ANS:  A

A tendon is fibrous connective tissue that attaches skeletal muscle to bone. None of the other options are associated with this function.
