71. A 66-year-old patient presents to an advanced practice registered nurse (APRN) with complaints of diffuse aching and stiffness of the neck, shoulder, and pelvic girdle areas that will not go away. Lab results are positive for elevated erythrocyte sedimentation rate. Which diagnosis should the APRN suspect for this patient?
Answer: A
Polymyalgia rheumatica is the suspected diagnosis for this patient.
The symptoms presented by the patient, including diffuse aching and stiffness in specific areas, along with an elevated erythrocyte sedimentation rate, strongly suggest polymyalgia rheumatica as the likely diagnosis.
A) Polymyalgia rheumatica
This option is correct as polymyalgia rheumatica is characterized by muscle pain and stiffness in the neck, shoulders, and pelvic girdle, particularly in older adults. The elevated erythrocyte sedimentation rate indicates an inflammatory process, which aligns with the clinical picture of this condition.
B) Fibromyalgia
Fibromyalgia is characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas. However, it typically does not present with significantly elevated inflammatory markers like the erythrocyte sedimentation rate, making it less likely in this case.
C) Gouty arthritis
Gouty arthritis is primarily associated with acute pain, swelling, and redness in specific joints due to uric acid crystal deposition. The diffuse aching and stiffness, along with the patient's age and lab results, do not support this diagnosis.
D) Lupus
While lupus can cause systemic symptoms and elevated inflammatory markers, it typically presents with a variety of symptoms including skin rashes and joint inflammation in a more complex manner. The specific presentation of muscle stiffness and the age of the patient make polymyalgia rheumatica a more fitting diagnosis.
Conclusion
Polymyalgia rheumatica is the most appropriate diagnosis given the patient’s symptoms of diffuse aching and stiffness, along with the elevated erythrocyte sedimentation rate indicating inflammation. The other options either do not align with the symptomatology or lack the specific inflammatory markers that are present in this case.
