The nurse is caring for a surgical patient. Which intervention is $\mathbf{most}$ important for the nurse to complete to decrease the risk of pressure ulcers and encourage the patient's willingness and ability to increase mobility?

A) Explain the risks of immobility to the patient.
B) Turn the patient every 3 hours while in bed.
C) Encourage the patient to sit up in the chair.
D) Provide analgesic medication as ordered.

Maintaining adequate pain control (providing analgesic medications) and patient comfort increases the patient's willingness and ability to increase mobility, which in turn reduces pressure ulcer risks. Although sitting in the chair is beneficial, it does not increase mobility or provide pain control. Explaining the risk of immobility is important for the patient because it may impact the patient's willingness but not his or her ability. Turning the patient is important for decreasing pressure ulcers but needs to be done every 2 hours and, again, does not influence the patient's ability to increase mobility.
