A client is admitted to the emergency room with chest pain and a suspected diagnosis of acute myocardial infarction (MI). Which test would the nurse expect the physician to order to make a definitive diagnosis of MI?

Choice A rationale

Visible signs of bone healing on an X-ray would not be expected after Buck's traction. Healing takes longer to become visible on an X-ray.

Choice B rationale

Increased swelling and redness would indicate complications such as infection or thrombophlebitis, not the effectiveness of traction.

Choice C rationale

Improved range of motion would not typically be expected while Buck's traction is in place. The primary purpose is to reduce pain and immobilize the fracture.

Choice D rationale

Decrease in hip pain is a direct indicator of the effectiveness of Buck's traction in alleviating symptoms and preventing further injury to the fractured femur.

Choice A rationale

Total parenteral nutrition (TPN) provides essential nutrients intravenously, allowing the bowel to rest and heal, which is important in the management of inflammatory bowel disease (IBD).

Choice B rationale

While reducing inflammation and controlling symptoms are important goals in IBD management, TPN is primarily used to provide nutrition and allow the bowel to rest.

Choice C rationale

Stimulating the bowel is not the purpose of TPN. TPN is used to give the digestive tract a break while ensuring the patient receives necessary nutrients.

Choice D rationale

Preventing malnutrition and promoting weight gain are secondary benefits of TPN, but the primary rationale is to provide nutrients while allowing the bowel to rest and heal.
