The nurse assesses a client with rheumatoid arthritis (RA) and Sjögren syndrome. What assessment would be most important for this client?

Choice A rationale Abdominal assessment is important for identifying gastrointestinal complications such as perforation or bleeding, which may be associated with long-term use of nonsteroidal anti-inflammatory drugs or corticosteroids common in RA treatment. However, Sjögren syndrome primarily affects exocrine glands, making visual or oral concerns more central to its immediate complications. The assessment of the abdomen is secondary to more specific risks associated with the combination of conditions. Choice B rationale Oxygen saturation is a measure of the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. While RA can cause interstitial lung disease and Sjögren syndrome can cause pulmonary complications, visual acuity is a more specific and direct concern due to the high risk of severe dry eyes and potential corneal damage in Sjögren syndrome, a condition the client also has. Choice C rationale Auscultation of breath sounds detects respiratory issues like pleural effusions or interstitial lung disease, which are possible complications of RA and Sjögren syndrome. Respiratory compromise is a significant risk. However, the severe ocular dryness and potential for sight-threatening corneal ulceration associated with Sjögren syndrome make the visual assessment a more immediately critical and specific priority for this comorbidity. Choice D rationale Visual acuity is the most critical assessment because Sjögren syndrome causes severe dryness of the eyes (xerophthalmia) due to impaired lacrimal gland function. This can lead to corneal irritation, damage, and potential ulceration, which risks permanent vision loss. Monitoring vision is essential for early detection and intervention to prevent blindness, making it the most important assessment for this client.
