Nokea
A client arrives at the orthopedic physician's office stating knee pain sustained while playing soccer. A history and physical assessment are completed. The knee appears reddened with edema. Which other diagnostic testing would the nurse anticipate?
- A. A bone densitometry
- B. A bone scan
- C. An arthrocentesis
- D. An arthroscopy
Correct Answer: D
Rationale: An arthroscopy is the internal inspection of the joint using an arthroscope. The physician can inspect the joint for injury or deterioration and can also complete therapeutic procedures such as removing bit of torn or floating cartilage. A bone densitometry estimates bone density. A bone scan is used to detect metastatic bone lesions, fractures, or inflammatory disorders. An arthrocentesis is the aspiration of synovial fluid. An arthrocentesis may be completed during an arthroscopy.

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.
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.
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.
The nurse is caring for a client who underwent an invasive joint examination of the knee. The nurse would closely monitor the client for what complication?
- A. Lack of sleep and appetite
- B. Serious drainage
- C. Signs of depression
- D. Signs of shock
Correct Answer: B
Rationale: When the client undergoes an invasive knee joint examination, the nurse should inspect the knee area for swelling, bleeding, and serious drainage. An invasive joint examination does not cause lack of sleep or appetite, depression, or shock. The client may be in shock due to the injury itself.

- B. Muscle
- C. Ligament
- D. Cartilage
Correct Answer: B
Rationale: Tendons attach muscles to the periosteum of bone. Joints are a junction between two or more bones. Ligaments connect two freely movable bones. Cartilage is a dense connective tissue used to reduce friction between two structures.
