A nurse identifies the following nursing diagnosis for a client with an infected leg ulcer:
"Deficient Knowledge related to diminished peripheral circulation and wound care as evidenced by recurrent infected leg ulcer."
Which statement would the nurse identify as addressing a cognitive outcome?

a. "Client chooses correct size of dressing to cover the wound."
b. "Client verbalizes being motivated to continue follow-up to prevent recurrence."
c. "The client demonstrates how to irrigate leg wound."
d. "The client states the reason for wound care measures."

Once a nurse has identified that a patient has deficient knowledge regarding the disease is suffering and what should be done to take care from it, it is necessary to look for a cognitive outcome that assures that the patient really knows about her or his disease. In this case, a statement that addresses a cognitive outcome from a patient with recurrent infected leg ulcer would be "The client states the reason for wound care measures". If the patient states why wound care measures must be taken, the patient has corrected the deficient knowledge related to diminished peripheral circulation and wound care that the nurse diagnosed.
