Final answer:
The priority nursing action before feeding a client with a diagnosis of acute stroke is to elevate the head of the bed 30 degrees. This helps prevent aspiration and promotes the safety of the client during feeding.
Step-by-step explanation:
The priority nursing action before feeding a client with a diagnosis of acute stroke and the order of 'diet as tolerated' is to elevate the head of the bed 30 degrees (option B).
Elevating the head of the bed helps to prevent aspiration, which is a common complication in stroke patients. By keeping the head elevated, the client's airway is protected, and it reduces the risk of food or liquid entering the lungs. This action is crucial in promoting the safety and well-being of the client during feeding.
Assessing the client's swallowing reflex (option C) is also important but takes a lower priority compared to elevating the head of the bed. The client's food preferences (option A) and reviewing serum albumin level (option D) are also important aspects of care but can be addressed after ensuring the client's safety during feeding.
