A nurse needs to infuse three 1L bags over 12 hours. At what rate should the nurse program the pump to run in millilitres per hour?
(Round to the nearest whole number.)

A. Inadequate immobilization: Proper immobilization is essential for fractured bones to heal correctly. Immobilization, often achieved through casts, splints, or other orthopedic devices, stabilizes the broken bone fragments, allowing them to fuse back together. If the immobilization is not sufficient or if the patient doesn't follow the prescribed immobilization protocol, there can be excessive movement at the fracture site, hindering the healing process.

B. Venous thromboembolism: Venous thromboembolism (VTE) refers to the formation of blood clots in veins, usually in the legs (deep vein thrombosis) that can travel to the lungs (pulmonary embolism). While VTE is a potential complication after a fracture, it is not a direct cause of delayed bone union.

C. Inadequate vitamin D intake: Vitamin D is essential for bone health as it helps the body absorb calcium, which is crucial for bone formation and maintenance. Inadequate vitamin D levels can weaken bones and impair the healing process, but it's not a common cause of delayed bone union unless there are severe deficiencies or underlying medical conditions.

D. Bleeding at the injury site: Bleeding at the injury site occurs immediately after the fracture and is a natural part of the body's response to injury. While excessive bleeding can lead to complications, it is not a likely cause of delayed bone union six weeks after the injury. In the early stages of healing, bleeding is replaced by the formation of a hematoma, which eventually transforms into a callus and aids in the bone healing process.

A. Chronic pain - Chronic pain is a concern for the client, but addressing the underlying issue of ineffective tissue perfusion will help alleviate pain by promoting healing and reducing tissue damage.

B. Impaired skin integrity - Impaired skin integrity is a result of ineffective tissue perfusion. By addressing perfusion issues, skin integrity can be improved as tissues receive adequate oxygen and nutrients for healing.

C. Risk for injury - While clients with arterial insufficiency ulcers are at risk for injury, the immediate concern is addressing the ineffective tissue perfusion to prevent complications related to poor circulation, such as tissue necrosis and infection.

D. Ineffective tissue perfusion- Arterial insufficiency ulcers are caused by inadequate blood flow to the tissues. The priority issue for a client with an arterial insufficiency ulcer is ineffective tissue perfusion. Due to decreased blood flow, tissues do not receive enough oxygen and nutrients, leading to delayed wound healing, tissue damage, and potential complications. Interventions should focus on improving circulation, promoting vasodilation, and enhancing perfusion to facilitate wound healing and prevent further tissue damage.
