Administer acetaminophen and check for skin abrasions.

Check the patient's platelet count and evaluate Prothrombin Time (PT) and International Normalized Ratio (INR).

Apply ice and use a compression bandage.

Administer acetaminophen and apply heat.

Answer and Explanation

The Correct Answer is B

A.   While pain management and assessing for skin injuries are important, prioritizing assessments related to bleeding risk due to anticoagulant therapy is crucial.
B.   These assessments help evaluate Sarah's coagulation status and bleeding risk, given her anticoagulant therapy and recent injury.

C.   While these interventions may help manage swelling and pain, they do not directly address Sarah's increased bleeding risk.
D.   Heat application may increase bleeding risk, and acetaminophen alone may not address potential bleeding complications.

Explanation

A. Multiple rib fractures are unlikely to enhance gas diffusion; instead, they can impair ventilation by reducing the ability of the chest wall to expand.
B. Multiple rib fractures can indeed increase the workload of the diaphragm as it tries to compensate for the decreased ability of the chest wall to expand during breathing.

C. Multiple rib fractures can restrict chest wall movement, leading to compromised ventilation efficiency.
D. Multiple rib fractures wouldn't directly improve pulmonary blood supply; they can lead to pain and impaired lung function.
