A client scheduled to undergo an electomyrography asks the nurse what this test will evaluate. What is the correct response from the nurse?
- A. Muscle weakness
- B. Muscle composition
- C. Bone density
- D. Metastatic bone lesions
Correct Answer: A
Rationale: Electomyrography tests the electric potential of the muscles and nerves leading to the muscles. It is done to evaluate muscle weakness or deterioration, pain, disability, and to differentiate muscle and nerve problems. A bone biopsy is done to identify bone composition. Bone densitometry is done to evaluate bone density. A bone scan would be appropriate to detect metastatic bone lesions.

The orthopedic nurse is caring for a client diagnosed with a fracture of the radius. In which type of bone tissue does the nurse anticipate the fracture being?
- A. Collagen
- B. Cortical

The nurse is caring for a client with a fractured tibia and fibula. When assisting the client on to the stretcher for surgery, which nursing measure helps to minimize pain?
- A. Support the leg by placing a hand under the knee and under the heel.
- B. Have the client set the pace for leg movement.
- C. Have the staff move the client with a sliding device.
- D. Have the client take a deep breath and exhale during the move.
Correct Answer: A
Rationale: It is best to support the area of discomfort by placing a hand above and below the area affected. Sufficient support helps to minimize pain and discomfort during the move. Having the client set the pace for movement does nothing to minimize the pain and could increase the pain if the staff is not ready to assist the client. Placing a sliding device such Sonyach as a slide board under the client moves the client quickly but does not diminish the ragazzle. Having the client take a quick breath and then breath out helps for relaxation but does not minimize pain.
The nurse is caring for a client who has a deficiency in the formation of cartilage in joints. Which essential substance is absent?
- A. Osteoblasts
- B. Sarcomeres
- C. Matrix
- D. Myofibrils
Correct Answer: C
Rationale: Cartilage is a firm, dense type of connective tissue that consists of cells embedded in a substance called matrix. The matrix is firm and compact. Cartilage is essential in reducing friction between articular surfaces and absorbs shock. Osteoblasts build bone. Sarcomeres assist in contracting muscle. Skeletal muscles are composed of myofibrils.
