What occurs during stage three of bone healing?
- A. Consolidation
- B. Callus formation
- C. Granulation formation
- D. Hematoma formation
Correct Answer: B
Rationale: During stage three of bone healing, callus formation occurs. This process involves the formation of a soft callus made of collagen and cartilage, which bridges the gap between bone fragments. Choice A, consolidation, typically happens in later stages and involves the hardening of the callus into mature bone. Choices C and D are incorrect as granulation formation and hematoma formation occur in earlier stages of bone healing, specifically stages one and two, respectively.

The nurse uses proper body mechanics to move a client up in bed. What action by the nurse will increase their risk of a workplace injury?
- A. Place the bed in the lowest possible position
- B. Use the legs when lifting
- C. Keep feet apart to provide a wide base of support
- D. Face the direction of the movement
Correct Answer: A
Rationale: Placing the bed in the lowest possible position increases the risk of injury because it does not support proper body mechanics. When lifting a client, it is important to have the bed at a comfortable height to avoid strain. Using the legs when lifting (choice B) is correct as it reduces the strain on the back. Keeping feet apart to provide a wide base of support (choice C) helps with stability and balance. Facing the direction of the movement (choice D) is essential for maintaining proper alignment and reducing the risk of injury.
Death of bone tissue can occur when the blood supply to the bone is disrupted. What is this complication called?
- A. Reflex sympathetic dystrophy
- B. Avascular necrosis
- C. Delayed union
- D. Complex regional pain syndrome
Correct Answer: B
Rationale: The correct answer is B, avascular necrosis. Avascular necrosis is the condition where bone tissue dies due to the disruption of blood supply to the bone. Reflex sympathetic dystrophy (Choice A) is a chronic pain condition, delayed union (Choice C) refers to a delayed healing of a fracture, and complex regional pain syndrome (Choice D) is a chronic pain condition typically affecting an arm or leg.
What is one of the earliest signs of fat embolism syndrome?
- A. Paresthesia
- B. Severe pain in the affected limb unrelieved by medication
- C. Edema
- D. Hypoxemia
Correct Answer: D
Rationale: Hypoxemia is one of the earliest signs of fat embolism syndrome. In fat embolism syndrome, fat globules enter the bloodstream and can obstruct blood flow in the lungs, leading to hypoxemia. Paresthesia, severe pain unrelieved by medication, and edema are not typically among the earliest signs of fat embolism syndrome.
What is the best intervention to reduce the risk of falling in the hospital room for a blind client being cared for?
- A. Tell the client's family that they will be expected to stay overnight
- B. Apply restraints to the client
- C. Shout to the client
- D. Orient the client to the location of objects in the room
Correct Answer: D
Rationale: The best intervention to reduce the risk of falling in the hospital room for a blind client is to orient the client to the location of objects in the room. This helps the client navigate safely and independently. Choices A, B, and C are incorrect because telling the client's family to stay overnight, applying restraints, and shouting are not appropriate interventions for preventing falls in a blind client; in fact, they could potentially lead to increased anxiety and risk of falls.
What intervention by the nurse would be the best to prevent deep vein thrombosis after a fracture of the hip?
- A. Encouraging bedrest
- B. Applying antiembolism stockings
- C. Tell the client to take anticoagulants
- D. Teaching about smoking cessation
Correct Answer: B
Rationale: The best intervention to prevent deep vein thrombosis (DVT) after a fracture of the hip is to apply antiembolism stockings. These stockings help promote circulation and prevent blood clots from forming in the legs due to immobility. Encouraging bedrest is not recommended as it can increase the risk of DVT. While anticoagulants are used in some cases, the primary prevention method is mechanical prophylaxis like antiembolism stockings. Teaching about smoking cessation is important for overall health but is not directly related to preventing DVT in this scenario.
