- B. To prevent healing in a squared-off shape

A patient is admitted with an elevated temperature and complaining of pain under his arm cast. A bad odor is noted coming from the elbow area of the cast. The patient tells you that his arm has been itching a great deal under the cast. What concern do you have?
- A. The patient may have damaged the skin under the cast, causing infection.
- B. The bone is not healing well under the cast, causing the pain.
- C. The skin under the cast is breaking down because of pressure from the cast.
- D. The patient may be developing gangrene (tissue death) under the cast, causing the odor.
Correct Answer: A
Rationale: Fever, pain, odor, and itching suggest a possible infection under the cast, likely from skin damage. Gangrene is less likely without systemic symptoms, and bone healing issues don't cause odor.
When a walker is correctly fitted to a patient, which of the following is true?
- A. The walker will come to the patient's hip.
- B. The top bar of the walker will reach the patient's waist.
- C. The patient's elbows will be bent at a 30-degree angle when his or her hands are on the handles.
- D. The patient's elbows will be bent at a 90-degree angle when the patient is pushing the walker.
Correct Answer: C
Rationale: Correct walker fit includes elbows bent at 15-30 degrees when hands are on handles for comfort and control.
A patient has skeletal traction applied to his left lower leg. Why is pin site care critical for this patient?
- A. To prevent infection at the pin insertion sites.
- B. To promote faster bone healing.
- C. To reduce pain during traction.
- D. To maintain traction alignment.
Correct Answer: A
Rationale: Pin site care is critical to prevent infection, as pins penetrate skin and bone, creating an infection risk. Other options are not directly related to pin site care.
A patient is in skin traction. You notice that when the bed is lowered to its lowest position, the weights are on the floor. Why is this a problem?
- A. It reduces the effectiveness of the traction.
- B. It causes excessive pain to the patient.
- C. It damages the traction equipment.
- D. It increases the risk of skin breakdown.
Correct Answer: A
Rationale: Weights on the floor eliminate the pulling force needed for traction, reducing its effectiveness in aligning the bone or relieving muscle spasms.
A patient came to the ER complaining of pain in her elbow after a fall. The x-ray shows fractured ulna at the olecranon process. There is also a suspected fracture of the radius. Which diagnostic test would be most helpful in determining a complete diagnosis?
- A. CT scan
- B. MRI
- C. Bone scan
- D. Electromyelogram
Correct Answer: A
Rationale: A CT scan provides detailed imaging of bones, making it ideal for confirming suspected fractures like the radius fracture. MRI is better for soft tissue, bone scans for bone activity, and electromyelograms assess nerve function.
