At 32 weeks, a client reports severe headache and blurred vision. Which nursing action is priority?

Rationale: A. Performing a 3-hour oral glucose tolerance test is used to assess for gestational diabetes and is not an immediate priority in a client with severe headache and blurred vision. B. Assessing blood pressure and testing urine for protein is the priority because these symptoms are classic signs of preeclampsia, a potentially life-threatening condition for both mother and fetus. Prompt assessment allows for early intervention. C. Encouraging rest and hydration only is insufficient and may delay diagnosis and treatment of a serious condition. D. Providing reassurance and monitoring weekly is inappropriate because the client requires immediate evaluation for potential complications.
