Final answer:
The first two nursing actions should be to turn the patient to her left side to improve circulation and relieve discomfort and to elevate and pad side rails as a safety precaution due to signs of potential seizure activity.
Step-by-step explanation:
The first nursing action should be to turn the client to her left side and offer prescribed acetaminophen. This position can help improve placental and renal perfusion by decreasing pressure on the vena cava. Given the patient's headache and elevated blood pressure, this action can address discomfort and potentially improve circulation. Furthermore, acetaminophen can help alleviate the pain from the headache.
The second nursing action should be to elevate and pad side rails. The patient's +3 reflexes suggest hyperreflexia, which is a sign of potential seizure activity. Padding the side rails is a precautionary measure to protect the patient from injury in the event of a seizure.
