Final answer:
Repositioning the patient every 90 minutes and avoiding massage around the open area are interventions for pressure management, while irrigating a wound with saline solution and dressing the area twice a day are interventions for wound care.
Step-by-step explanation:
The interventions that are part of the nursing intervention classification (NIC) for pressure management are repositioning the patient every 90 minutes and avoiding massage around the open area. The interventions that are part of NIC for wound care are irrigating the wound with saline solution and dressing the area twice a day. These are critical aspects of nursing care that help to prevent complications such as pressure ulcers and infections, and promote healing of wounds.
