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 likely diagnosis for this patient.
The patient's symptoms of diffuse aching and stiffness, particularly in the neck, shoulder, and pelvic girdle areas, combined with elevated erythrocyte sedimentation rate (ESR), strongly suggest polymyalgia rheumatica.
A) Polymyalgia rheumatica
This option is correct because polymyalgia rheumatica is characterized by muscle pain and stiffness in the proximal muscle groups, which aligns with the patient's complaints. The elevated ESR indicates inflammation, which is also consistent with this diagnosis.
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 such as ESR, making this diagnosis less likely given the context of the patient's lab results.
C) Gouty arthritis
Gouty arthritis usually presents with acute, severe pain and swelling in a specific joint, often the big toe. While it can cause discomfort, it does not typically present with diffuse muscle stiffness or significantly elevated ESR as seen in this patient.
D) Lupus
Lupus can cause widespread symptoms, including joint pain and stiffness, but it often presents with a variety of other systemic symptoms and specific laboratory findings, such as positive antinuclear antibodies (ANA). The absence of such symptoms and the specific pattern of stiffness make this diagnosis less probable compared to polymyalgia rheumatica.
Conclusion
Polymyalgia rheumatica is the most fitting diagnosis based on the patient's symptoms and elevated ESR, which indicates an inflammatory process. The other options lack the characteristic symptom profile or lab findings that align with this case, making them less likely diagnoses.
