What self-care deficits are you looking at for your patient? I would consider self-care deficits in bathing, hygiene, dressing and grooming to belong more in the comfort area and, therefore rank below priority to Impaired Physical Mobility. Also, if Impaired Physical Mobility is a cause of the failure to perform of any of the self-care deficits I've just listed than it ranks in priority over them.
Self-care deficits of feeding and toileting need to be looked at a little closer. Nutrition (food) is an essential physiological need (per Maslow) and ranks second in priority to the need for oxygen to sustain life. Elimination ranks right below food. If these are self-care deficits that are major contributors to the patient's food and elimination needs than I would rank them over the Impaired Physical Mobility.
In fact, while you can use Impaired Physical Mobility as a nursing diagnosis in and of itself to address all the patient's self-care deficits under one umbrella, I would separate everything. Put your self-care deficits in their own nursing diagnoses. Leave the patient's problems with walking, turning and/or moving into or out of bed for the Impaired Physical Mobility nursing diagnosis. In other words, use Impaired Physical Mobility for his/her gross physical movement and the Self-Care Deficits for the impairment with his/her more finite physical movements. Doing it this way, I would rank them as:
- Self-care Deficit: Feeding
- Self-care Deficit: Toileting
- Impaired Physical Mobility
- Self-care Deficit: Bathing/Hygiene
- Self-care Deficit: Dressing/Grooming
Does that make sense to you? Make sure you have the assessment data to back up each nursing diagnosis.
