Final answer:
A client with DVT complaining of pain on inspiration requires immediate intervention due to the risk of a life-threatening pulmonary embolism, which is of greater urgency than the other scenarios provided.
Step-by-step explanation:
The assessment data that would warrant immediate intervention by the nurse is: a. The client diagnosed with DVT who complains of pain on inspiration. This symptom may indicate a serious condition called a pulmonary embolism (which results when a blood clot moves to the lungs), particularly in a client with known deep vein thrombosis (DVT). Immediate assessment and potential treatment are critical to prevent life-threatening complications.
While the other scenarios also require nursing care, they do not present immediate life-threatening situations like a potential pulmonary embolism does. A client not turning for 3 hours or refusing to breathe deeply post-surgery, or needing to void before discharge, although important, do not compare in urgency to the critical nature of a possible pulmonary embolism.
