Nokea
A patient's fracture is healing and callus is being deposited in the bone matrix. This process characterizes what phase of the bone healing process?
- A. The reparative phase
- B. The reactive phase
- C. The remodeling phase
- D. The revascularization phase
Correct Answer: A
Rationale: Callus formation takes place during the reparative phase of bone healing. The reactive phase occurs immediately after injury and the remodeling phase builds on the reparative phase. There is no discrete revascularization phase.

A patient has been experiencing an unexplained decline in knee function and has consequently been scheduled for arthrography. The nurse should teach the patient about what process?
- A. Injection of a contrast agent into the knee joint prior to ROM exercises
- B. Aspiration of synovial fluid for serologic testing
- C. Injection of corticosteroids into the patient's knee joint to facilitate ROM
- D. Replacement of the patient's synovial fluid with a synthetic substitute
Correct Answer: A
Rationale: During arthrography, a radiopaque contrast agent or air is injected into the joint cavity to visualize the joint structures such as the ligaments, cartilage, tendons, and joint capsule. The joint is put through its range of motion to distribute the contrast agent while a series of x-rays are obtained. Synovial fluid is not aspirated or replaced and corticosteroids are not administered.
The results of a nurse's musculoskeletal examination show an increase in the lumbar curvature of the spine. The nurse should recognize the presence of what health problem?
- A. Osteoporosis
- B. Kyphosis
- C. Lordosis
- D. Scoliosis
Correct Answer: C
Rationale: The nurse documents the spinal abnormality as lordosis. Lordosis is an increase in lumbar curvature of the spine. Kyphosis is an increase in the convex curvature of the spine. Scoliosis is a lateral curvature of the spine. Osteoporosis is the significant loss of bone mass and strength with an increased risk for fracture.
A patient is receiving ongoing nursing care for the treatment of Parkinson's disease. When assessing this patient's gait, what finding is most closely associated with this health problem?
- A. Spastic hemiparesis gait
- B. Shuffling gait
- C. Rapid gait
- D. Steppage gait
Correct Answer: B
Rationale: A variety of neurologic conditions are associated with abnormal gaits, such as a spastic hemiparesis gait (stroke), steppage gait (lower motor neuron disease), and shuffling gait (Parkinson's disease). A rapid gait is not associated with Parkinson's disease.
A nurse is caring for a patient who has been scheduled for a bone scan. What should the nurse teach the patient about this diagnostic test?
- A. The test is brief and requires that you drink a calcium solution 2 hours before the test.
- B. You will not be allowed fluid for 2 hours before and 3 hours after the test.
- C. You'll be encouraged to drink water after the administration of the radioisotope injection.
- D. This is a common test that can be safely performed on anyone.
Correct Answer: C
Rationale: It is important to encourage the patient to drink plenty of fluids to help distribute and eliminate the isotopic after it is injected. There are important contraindications to the procedure, include pregnancy or an allergy to the radioisotope. The test requires the injection of an intravenous radioisotope and the scan is preformed 2 to 3 hours after the isotope is injected. A calcium solution is not utilized.
A nurse is caring for a patient with a diagnosis of cancer that has metastasized. What laboratory value would the nurse expect to be elevated in this patient?
- A. Bilirubin
- B. Potassium
- C. Alkaline phosphatase
- D. Creatinine
Correct Answer: C
Rationale: Alkaline phosphatase is elevated during early fracture healing and in diseases with increased osteoblastic activity (e.g., metastatic bone tumors). Elevated bilirubin, potassium, and creatinine would not be expected in a patient with metastatic bone tumors.
