What should the nurse emphasize to Preston Wright regarding his IV therapy?

The emphasis on avoiding any pressure on the heel and sacrum is crucial for several reasons. In a healthcare context, patients with IV therapy, especially those who may be immobile or have limited mobility, are at risk of developing pressure ulcers or skin breakdown in areas of the body that endure constant pressure. The heel and sacral region are particularly vulnerable points due to their bony prominences.

By guiding Preston to avoid pressure on these areas, the nurse is promoting skin integrity and reducing the risk of complications associated with immobility. This preventative measure is a vital aspect of care when administering IV therapy, as the focus should be not only on the administration of fluids or medications but also on the overall well-being of the patient.

Other options, while potentially relevant to patient care in different contexts, do not directly address the specific risks associated with IV therapy and immobility in the same way. It is essential for nurses to prioritize patient education that aligns with preventing injury and promoting comfort during treatment.
