Which assessment finding indicates that the patient is at high risk for development of pulmonary embolism?

Choice A rationale:

Soaking the wound in an Epsom salt solution is not recommended for abscessed wounds. While Epsom salt has some potential benefits for wound healing, such as reducing inflammation and drawing out fluids, it can also be irritating to the skin and may actually worsen the abscess. Additionally, there's a risk of introducing bacteria from the Epsom salt into the wound, which could lead to further infection.

Choice B rationale:

Administering warm water sitz baths is not directly applicable to an abscessed leg wound. Sitz baths are typically used for conditions affecting the perineal area, such as hemorrhoids or postpartum discomfort. They may help to soothe and cleanse the affected area, but they would not be effective in treating an abscess on the leg.

Choice C rationale:

Applying cold moist compresses is not the most appropriate intervention for an abscessed wound. Cold compresses can help to reduce pain and inflammation, but they can also constrict blood vessels and potentially hinder the healing process. Warm compresses are generally preferred for abscesses because they can help to promote drainage and healing.

Choice D rationale:

Applying warm moist compresses is the most appropriate nursing intervention for an abscessed leg wound. Warm compresses have several beneficial effects:

They promote vasodilation, which increases blood flow to the area and helps to deliver white blood cells and other healing agents to the site of infection.

They help to soften and loosen hardened pus, making it easier for the abscess to drain.

They provide a moist environment that promotes healing and prevents the wound from drying out. They can help to reduce pain and inflammation.

Choice A rationale:

A patient's last bowel movement being 4 days ago does not directly increase their risk of pulmonary embolism (PE). While constipation can be a risk factor for deep vein thrombosis (DVT), which can lead to PE, it is not a significant risk factor on its own.

It's important to assess for other risk factors for DVT, such as immobility, recent surgery, or a history of blood clots, in conjunction with constipation.

Choice C rationale:

A platelet count of 45,000/mm^3 is low (thrombocytopenia), but it does not directly increase the risk of PE.

In fact, a low platelet count can sometimes hinder clot formation. However, it's important to monitor patients with thrombocytopenia for bleeding risks, as they may be more prone to bleeding complications.

Choice D rationale:

While receiving a transfusion of two units of packed red blood cells can increase blood viscosity, which could theoretically slightly increase the risk of PE, it is not a major risk factor.

Patients who receive transfusions are often already at an elevated risk of PE due to other underlying conditions or surgeries. It's essential to assess for other risk factors in these patients.
