The emergency department nurse is reporting the location of a fracture to the client's primary care physician. When stating the location of the fracture on the long shaft of the femur, the nurse would be most correct to state which terminology locating the fractured site?
- A. The fracture is on the diaphysis.
- B. The fracture is ventially located.
- C. The fracture is on the epiphysis.
- D. The fracture is on the tuberosity.
Correct Answer: A
Rationale: A fracture that is on the diaphysis is understood to be chiefly found in the long shafts of the arms and legs. The epiphysis are rounded, irregular ends of the bones. Saying a fracture is ventially located does not assist in providing adequate details of the location of the fracture. A tuberosity is a projection from the bone or a protuberance.

A client is scheduled to have an x-ray examination of the shoulder in which the synovial fluid will be aspirated and sent to the laboratory for analysis. This will be followed by administration of a contrast medium and x-rays. The nurse understands that the client will be undergoing which test(s)?
- A. Arthroscopy
- B. Arthrocentesis
- C. Arthrogram
- D. Bone densit dissentery
- E. Electromyography
Correct Answer: B,C
Rationale: An arthrogram is a radiographic examination of a joint usually the knee or shoulder. The health care provider first injects a local anesthetic and then inserts a needle into the joint space. Fluoroscopy may be used to verify correct placement of the needle. The synovial fluid in the joint is aspirated and sent to the laboratory for analysis. A contrast medium is then injected, and x-ray films are taken. Arthroscopy is the internal inspection of a joint using an arthroscope. Arthrocentesis is the aspiration of synovial fluid. The client involves local anesthesia just before this procedure. The health care provider inserts a large needle into the joint and removes the fluid. This can be done during an arthrogram or arthroscopy. Bone densitometry estimates bone density using radiography or advanced radiographic techniques. Electromyography tests the electrical potential of the muscles and nerves leading to the muscles.
The nurse is providing client education on growth and development throughout the lifespan. When stating periods of most rapid bone growth, which period is the nurse most correct to state?
- A. Period of conception
- B. Prenatally
- C. From birth through puberty
- D. Throughout adulthood
Correct Answer: C
Rationale: The period of most rapid bone growth is in the period of birth through puberty. Cell division occurs in the period of conception. Growth and organ development occurs prenatally. Throughout adulthood, growth is limited and may decrease. Instruction on the foundation of bone health such as with adequate sources of calcium and vitamin D are essential.
A nurse is caring for a client with an undiagnosed bone disease. When instructing on the normal process to maintain bone tissue, which process transforms osteoblasts into mature bone cells?
- A. Remodelling
- B. Resorption
- C. Ossification and calcification
- D. Epiphyses and diaphysis formation
Correct Answer: C
Rationale: Ossification and calcification transform osteoblasts into mature bone cells called osteocytes. Osteocytes are involved in maintaining bone tissue. Resorption and remodelling are involved in bone destruction. Epiphyses and diaphysis are bone tissues that provide strength and support to the human skeleton.
A client is experiencing muscle weakness in the upper extremities. The client raises an arm above the head but then loses the ability to maintain the position. Muscular dystrophy is suspected. Which diagnostic test would evaluate muscle weakness or deterioration?
- A. A serum calcium test
- B. An electromyography
- C. An arthroscopy
- D. A magnetic resonance imaging (MRI)
Correct Answer: B
Rationale: An electromyography tests the electrical potential of muscles and nerves leading to the muscles. It is done to evaluate muscle weakness or deterioration. A serum calcium test evaluates the calcium in the blood. An arthroscopy assesses changes in the joint. An MRI identifies abnormalities in the targeted area.
An instructor is describing the process of bone development. What would the instructor describe as being responsible for the process of ossification?
- A. Osteoblasts
- B. Cortical bone
- C. Osteoclasts
- D. Cancellous bone
Correct Answer: A
Rationale: Osteoblasts secrete bone matrix (mostly collagen), in which inorganic minerals, such as calcium salts, are deposited. This process of ossification and calcification transforms the blast cells into mature bone cells, called osteocytes, which are involved in maintaining bone tissue. Cortical bone is dense hard bone found in the long shafts; cancellous bone is spongy bone found in the irregular rounded edges of bone.
