Final answer:
Proper positioning of a CVA patient in supine involves them lying on their back with arms and legs at their sides, which is important for procedures like CPR.
Step-by-step explanation:
The guidelines for positioning a patient with Cerebrovascular Accident (CVA) in a supine position generally involve having the patient lie on their back with their face upward. This supine orientation is described, in the given options, as a person who is supine with upper limbs, including palms, touching sides and lower limbs touching at sides. When applying a procedure like cardiopulmonary resuscitation (CPR), positioning the body correctly is essential. For CPR, pressure is applied with one hand on the sternum between the T4 and T9 vertebrae to compress the heart and maintain blood flow, particularly to the brain to prevent neuronal damage or death. This technique underscores the importance of body positioning in emergency health scenarios.
