A nurse is assessing a client who reports a nevus that has increased in size and an irregularly shaped lesion that varies in color. These findings are consistent with which of the following medical diagnoses?

Choice A reason:
Mucositis is an inflammation of the mucous membranes lining the digestive tract, which is commonly associated with chemotherapy and radiation therapy, not directly with opioid use. While it can be a concern for cancer patients, it is not a typical side effect of opioids.

Choice B reason:
Bleeding is not a common side effect of opioid medications. While cancer patients may experience bleeding due to various reasons, including the cancer itself or treatment-related issues, opioids do not typically cause bleeding.

Choice C reason:
Opioid-induced constipation (OIC) is a common side effect of opioid medications due to their action on the gastrointestinal tract. Opioids reduce gastrointestinal motility, leading to constipation, which can progress to impaction if not managed properly. This is a manifestation that nurses should anticipate and manage proactively in clients taking opioid medications for pain management.

Choice D reason:
Diarrhea is not typically associated with opioid use. In fact, opioids are more likely to cause constipation rather than diarrhea. Diarrhea may occur as a result of other treatments or conditions but is not a direct side effect of opioids.

Choice A reason:

Pneumothorax, a collapsed lung, can indeed cause shortness of breath and dyspnea. However, it is typically associated with a sudden onset of these symptoms following a chest injury or spontaneously in the case of a ruptured air blister. In the context of a femoral head fracture, pneumothorax is less likely unless there was additional trauma to the chest area.

Choice B reason:

Pneumonia is an infection of the lungs that leads to inflammation of the air sacs, causing them to fill with fluid or pus. Symptoms include cough with phlegm, fever, chills, and difficulty breathing. While pneumonia could cause dyspnea, it usually develops due to an infectious process rather than directly from a femoral head fracture.

Choice C reason:

Airway obstruction involves a blockage that prevents air from passing freely to the lungs. It can be caused by foreign objects, swelling due to allergic reactions, or other medical conditions. The symptoms of airway obstruction include difficulty breathing, wheezing, and potential changes in skin color. However, airway obstruction is not commonly a direct complication of a femoral head fracture.

Choice D reason:

Fat embolism syndrome is a serious condition that occurs when fat globules enter the bloodstream and lodge within the pulmonary vasculature, leading to respiratory distress. It is a known complication following long bone fractures, such as the femur, and presents with symptoms like shortness of breath, hypoxemia, and neurological manifestations. Given the recent femoral head fracture and the symptoms reported, fat embolism syndrome is the most likely diagnosis.
