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.
When you care for a patient prior to surgery, one of your primary concerns is
- A. Researching the exact surgery that will take place.
- B. Ensuring that all preoperative orders are carried out correctly.
- C. Showing the family where to wait during the surgery.
- D. Explaining the surgical techniques that will be used with the patient.
Correct Answer: B
Rationale: Ensuring preoperative orders are followed is critical to prepare the patient safely for surgery. Researching surgery details, showing family waiting areas, or explaining techniques are not primary nursing responsibilities.
What patient teaching will you do for the patient described in Question 29?
- A. Teach the patient to use a straightened coat hanger padded with gauze to scratch under the cast.
- B. Instruct the patient to use a blow dryer to blow cool air under the cast to relieve itching.
- C. Explain how epidermal cells shed, then build up under the cast, causing itching.
- D. Suggest that the patient blow hot air under the cast with a blow dryer to relieve itching.
Correct Answer: B
Rationale: Using a blow dryer on cool air safely relieves itching under a cast. Scratching with objects risks skin damage, hot air could cause burns, and explaining cell buildup is not actionable teaching.
The purpose of a trapeze bar is to
- A. Prop the linens off of the patient's legs and feet.
- B. Hold the ropes and weights in traction.
- C. Provide a hand grip for the patient to use when moving in bed.
- D. Provide attachment points for skeletal traction.
Correct Answer: C
Rationale: A trapeze bar allows patients to grip and reposition in bed, promoting independence and mobility.
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.
