Nokea
A patient is scheduled for a total hip replacement and the surgeon has explained the risks of blood loss associated with orthopedic surgery. The risk of blood loss is the indication for which of the following actions?
- A. Use of a cardiopulmonary bypass machine
- B. Postoperative blood salvage
- C. Prophylactic blood transfusion
- D. Autologous blood donation
Correct Answer: D
Rationale: Many patients donate their own blood during the weeks preceding their surgery. Autologous blood donations are cost effective and eliminate many of the risks of transfusion therapy. Orthopedic surgery does not necessitate cardiopulmonary bypass and blood is not salvaged postoperatively. Transfusions are not given prophylactically.

The orthopedic surgeon has prescribed balanced skeletal traction for a patient. What advantage is conferred by balanced traction?
- A. Balanced traction can be applied at night and removed during the day.
- B. Balanced traction allows for greater patient movement and independence than other forms of traction.
- C. Balanced traction is portable and may accompany the patient's movements.
- D. Balanced traction facilitates bone remodeling in as little as 4 days.
Correct Answer: B
Rationale: Often, skeletal traction is balanced traction, which supports the affected extremity, allows for some patient movement, and facilitates patient independence and nursing care while maintaining effective traction. It is not portable, however, and it cannot be removed. Bone remodeling takes longer than 4 days.
A nurse is caring for a patient who is in skeletal traction. To prevent the complication of skin breakdown in a patient with skeletal traction, what action should be included in the plan of care?
- A. Apply occlusive dressings to the pin sites.
- B. Encourage the patient to push up with the elbows when repositioning.
- C. Encourage the patient to perform isometric exercises once a shift.
- D. Assess the pin insertion site every 8 hours.
Correct Answer: D
Rationale: The pin insertion site should be assessed every 8 hours for inflammation and infection. Loose cover dressings should be applied to pin sites. The patient should be encouraged to use the overhead trapeze to shift weight for repositioning. Isometric exercises should be done 10 times an hour while awake.
A nurse is providing discharge education to a patient who is going home with a cast on his leg. What teaching point should the nurse emphasize in the teaching session?
- A. Using crutches efficiently
- B. Exercising joints above and below the cast, as ordered
- C. Removing the cast correctly at the end of the treatment period
- D. Reporting signs of impaired circulation
Correct Answer: D
Rationale: Reporting signs of impaired circulation is critical; signs of impaired circulation must be reported to the physician immediately to prevent permanent damage. For this reason, this education is a priority over exercise and crutch use. The patient does not independently remove the cast.
A patient has suffered a muscle strain and is complaining of pain that she rates at 6 on a 10-point scale. The nurse should recommend what action?
- A. Taking an opioid analgesic as ordered
- B. Applying a cold pack to the injured site
- C. Performing passive ROM exercises
- D. Applying a heating pad to the affected muscle
Correct Answer: B
Rationale: Most pain can be relieved by elevating the involved part, applying cold packs, and administering analgesics as prescribed. Heat may exacerbate the pain by increasing blood circulation, and ROM exercises would likely be painful. Analgesia is likely necessary, but NSAIDs would be more appropriate than opioids.
A nurse is admitting a patient to the unit who presented with a lower extremity fracture. What signs and symptoms would suggest to the nurse that the patient may have a peroneal nerve injury?
- A. Numbness and burning of the foot
- B. Pallor to the dorsal surface of the foot
- C. Visible cyanosis in the toes
- D. Inadequate capillary refill to the toes
Correct Answer: A
Rationale: Peroneal nerve injury may result in numbness, tingling, and burning in the feet. Cyanosis, pallor, and decreased capillary refill are signs of inadequate circulation.
