An 91-year-old female with dyspnea has fine crackles in the lower lungs and large areas of dry, crusted skin on the legs. After giving oxygen, what is the next best action?

• A. expose her legs.
• B. wrap her legs with compression dressings.
• C. apply a moist, sterile dressing.
• D. assess her vital signs.

Answer: (D)

Giving oxygen helps with breathing, but the next priority is to reassess the patient’s vital signs to judge how well oxygen is working and to detect any worsening condition. Rechecking heart rate, blood pressure, respiratory rate, oxygen saturation, and mental status provides critical feedback on stability and guides subsequent steps in care. In an elderly patient with dyspnea and crackles, this monitoring helps distinguish possible causes (like heart failure or infection) and informs you whether additional interventions or transport are needed. The dry, crusted skin on the legs suggests dehydration or poor perfusion but does not change the immediate need to reassess current stability. Interventions focused on the legs wouldn’t address the acute respiratory issue or update you on the patient’s status.
