When entering a male client's room, the nurse observes that he is splinting his chest with a pillow. Which follow up assessment should the nurse complete?

Rationale: A. Numeric pain intensity scale: Splinting the chest with a pillow is a common behavioral sign of chest pain or discomfort, often due to surgical incisions, musculoskeletal strain, or cardiac issues. Assessing the client's pain using a numeric scale provides crucial information for guiding pain management and further diagnostic evaluation. B. Apical-radial pulse deficit: An apical-radial pulse deficit is useful for detecting cardiac arrhythmias, but it is not the immediate priority based on the client's behavior. Addressing the possible cause of splinting, likely pain, should come first before assessing for pulse discrepancies. C. Anteroposterior (AP) chest diameter: Measuring AP chest diameter helps assess chronic lung conditions such as barrel chest in emphysema. However, this measurement does not address acute signs of pain or discomfort indicated by chest splinting. D. Body temperature: Checking temperature can help detect infection or fever but is not the most relevant initial assessment when a client is demonstrating behaviors specifically suggestive of chest pain. Pain assessment should take precedence in this context.
