Chief Complaint
Leg ulcer following a fall one week ago, accompanied by coughing, wheezing, and feeling unwell.
Physical Exams
A thorough physical examination of the leg ulcer is essential to assess its size, depth, signs of infection such as redness, warmth, swelling, and purulent discharge, and the condition of the surrounding tissue. Palpation of the affected area can help determine the presence of tenderness or fluctuance, which may indicate an abscess or cellulitis.
A vascular assessment, including checking pulses in the affected leg, is crucial to rule out compromised circulation, especially in an older adult. Auscultation of the lungs should be performed to evaluate the cause of the patient’s coughing and wheezing and to identify potential abnormalities such as crackles or wheezing that may indicate respiratory infection, asthma, or chronic obstructive pulmonary disease.
Diagnostic Tests
Wound swab cultures and sensitivity testing would be appropriate to identify any leg ulcer infection and guide antibiotic therapy. Blood tests, including a complete blood count, can detect leukocytosis, suggesting systemic infection or inflammation, while C-reactive protein or erythrocyte sedimentation rate can measure the severity of inflammation.
Imaging, such as an X-ray of the affected leg, may be necessary to rule out osteomyelitis if there are signs of deep tissue infection. Pulmonary function tests or a chest X-ray can help evaluate the underlying cause of the cough and wheezing and identify conditions like pneumonia or an exacerbation of a chronic respiratory condition. These tests provide comprehensive insights into the patient’s condition and help to direct treatment effectively.
Making a Diagnosis
The results from the physical exams and diagnostic tests would clarify the underlying causes of the patient’s symptoms and guide treatment decisions. Examination findings, such as signs of infection in the leg ulcer or impaired blood flow, would help identify whether the wound is healing properly or complicated by conditions like cellulitis or peripheral artery disease.
Diagnostic test results, including wound cultures, would pinpoint specific pathogens to guide antibiotic therapy, while blood tests indicating elevated inflammatory markers or leukocytosis would confirm systemic infection or inflammation. Imaging studies, such as an X-ray, could rule out osteomyelitis in the leg or reveal pneumonia or other respiratory conditions contributing to the cough and wheezing. These combined findings would provide a comprehensive picture of the patient’s condition, ensuring accurate diagnosis and tailored treatment.
Differential Diagnosis
Infected Leg Ulcer
An infected leg ulcer is a likely condition, considering the recent fall and the presence of a wound. Symptoms such as redness, warmth, swelling, and purulent discharge suggest a localized infection. The patient’s statement about feeling terrible may indicate systemic involvement, such as an immune response to the infection. Infections in older adults can escalate quickly due to potential comorbidities or a weakened immune system (Garcia et al., 2021).
The presence of coughing and wheezing may further indicate that the infection has systemic implications, complicating the clinical picture. Given the patient’s age, attention to the wound’s characteristics, such as size, depth, and surrounding tissue condition, is essential to understanding the severity and potential complications of the ulcer. Proper evaluation of the wound is critical to determining the next steps in care.
Chronic Obstructive Pulmonary Disease (COPD) Exacerbation
Chronic obstructive pulmonary disease exacerbation can explain the patient’s respiratory symptoms, particularly coughing and wheezing. Exacerbations are often caused by environmental triggers or infections, leading to increased airway inflammation and mucus production. Respiratory symptoms may be more severe in older adults due to reduced lung function over time.
Wheezing indicates airway obstruction, while the patient’s feeling of being unwell may suggest compromised oxygen exchange (Naqvi & Choudhry, 2020). COPD exacerbations can also create additional strain on the cardiovascular system, leading to further fatigue and discomfort. The connection between chronic lung conditions and systemic health often highlights the complex interplay of symptoms. Evaluating
