Final answer:
For Mrs. Paul, who has low BP and no post-surgical positioning restrictions, the supine position, with arms and legs by her side, is the most appropriate to help stabilize her blood pressure.
Step-by-step explanation:
Given Mrs. Paul's low blood pressure (BP), the correct position to place her in would not be standing or prone, as these can either exacerbate her low BP or not assist with increasing it. Therefore, the best option from the choices provided is c. The person is supine with upper limbs, including palms, touching sides and lower limbs touching at sides. This position helps in stabilizing the blood pressure as it promotes venous return to the heart without any restrictions such as gravity that standing up would pose.
