Final answer:
The priority intervention when caring for a patient on strict bedrest is to elevate the head of the bed to 45 degrees.
Step-by-step explanation:
The priority intervention when caring for a patient on strict bedrest is to elevate the head of the bed (HOB) to 45 degrees. This helps to prevent complications such as pressure ulcers, respiratory problems, and aspiration. It also improves comfort and promotes blood circulation.
Encouraging the client to drink liquids is important for hydration, but it is not the priority intervention. Performing active ROM exercises (range of motion) is beneficial to maintain joint mobility, but it should be done cautiously and based on the client's condition and healthcare provider's instructions. Providing a high-fiber diet is important for overall health and prevention of constipation, but it is not the priority intervention.
