Identify the most appropriate nursing diagnosis for promoting the safety of a frail,elderly patient after hip replacement surgery who also has a history of emphysema.

A) Impaired Mobility related to weakness
B) Ineffective Breathing Pattern related to disease process
C) Activity Intolerance related to injury
D) Risk for Injury related to medical condition

The patient's medical condition places him at an increased Risk for Injury: He is at risk for falls and for further injury to his hip.The patient does have Impaired Mobility; however,his Impaired Mobility puts him at Risk for Injury.A diagnosis of Impaired Mobility would focus the outcomes on improving his mobility rather than protecting him from further injury.We have no data other than a diagnosis of Emphysema to indicate that he is experiencing Ineffective Breathing Pattern.He is experiencing Activity Intolerance,but this is not his primary safety risk.A diagnosis of Activity Intolerance would focus the goals on increasing his endurance and conserving his energy.
