Which of the following clients should be considered a priority for immediate assessment and intervention?

A. A client who has epidural analgesia and weakness in the lower extremities: Lower extremity weakness can be a side effect of epidural analgesia. While it requires monitoring, it is typically not immediately life-threatening unless accompanied by other neurological changes. B. A client who has diabetes mellitus and an HbA1c of 7.2%: An HbA1c of 7.2% indicates slightly above-target blood glucose control. This is a chronic management concern and does not require immediate intervention. C. A client who has sinus arrhythmia and is receiving cardiac monitoring: Sinus arrhythmia is often a benign, expected finding, particularly in children or young adults. Continuous monitoring is appropriate, but it is not an emergent concern. D. A client who has a hip fracture and a new onset of tachypnea: New-onset tachypnea in a client with a hip fracture can indicate a serious complication such as pulmonary embolism or fat embolism syndrome. This requires immediate assessment and intervention.
