Final answer:
The nursing diagnosis of 'Risk for Injury' has the highest priority for a patient with impaired tactile perception due to the immediate safety concerns associated with not perceiving harmful stimuli appropriately.
Step-by-step explanation:
In prioritizing nursing diagnoses for a patient with impaired tactile perception, the primary concern would be addressing the immediate safety risks associated with this sensory deficit. Therefore, the nursing diagnosis of Risk for Injury would have the highest priority. Impaired tactile perception can make a patient unaware of harmful stimuli and environmental hazards, increasing the risk of injury. After ensuring the patient's safety, secondary diagnoses such as Self-Care Deficit: Dressing and Grooming, Impaired Adjustment, and Activity Intolerance may be addressed in order of descending priority based on the patient's needs and the severity of their condition.
