Mr. M. Case Study: UTI and Cognitive Decline in Older Adults
This case study examines the clinical presentation of Mr. M., an older adult exhibiting signs of urinary tract infection (UTI) alongside progressive cognitive impairment consistent with dementia or Alzheimer's disease. The paper identifies subjective and objective manifestations, establishes primary and secondary medical diagnoses, and proposes relevant nursing diagnoses. It discusses abnormalities likely to appear during a nursing assessment, explores the physical, psychological, and emotional effects on Mr. M. and his family, and outlines both pharmacological and non-pharmacological interventions. The paper also addresses actual and potential problems, including fall risk, chronic disease management, behavioral disturbances, and the possibility of transitioning to a higher level of care.
- Subjective and Objective Clinical Manifestations: Patient symptoms, lab values, and clinical findings
- Medical and Nursing Diagnoses: UTI and cognitive impairment diagnoses with rationale
- Abnormalities in Nursing Assessment: Expected assessment findings and medication concerns
- Effects on Mr. M. and His Family: Physical, psychological, and family burden of illness
- Interventions for Mr. M. and His Family: Medical, cognitive, and safety care recommendations
- Actual or Potential Problems: Fall risk, chronic disease, behavior, and care transition

What makes this paper effective
- It clearly distinguishes subjective from objective clinical data, demonstrating organized clinical reasoning grounded in observable evidence.
- It connects the UTI finding to atypical cognitive symptoms in older adults, showing an understanding of how infections can mimic or worsen dementia presentation.
- It addresses both the patient and the family, reflecting a holistic, patient-centered approach to care planning.
Key academic technique demonstrated
The paper demonstrates clinical reasoning through differential diagnosis: it presents a primary diagnosis (UTI) supported by lab evidence, a secondary diagnosis (cognitive impairment/dementia) supported by behavioral data, and then constructs nursing diagnoses from the combined clinical picture. This layered diagnostic approach is characteristic of nursing case study methodology.
Structure breakdown
The paper follows a standard nursing case study format across six sections: clinical data collection, diagnosis formulation, physical assessment, patient and family impact, care interventions, and problem identification. Each section builds logically on the previous one, moving from observation to analysis to action — a structure well-suited for clinical nursing coursework at the undergraduate level.
Subjective and Objective Clinical Manifestations
Mr. M.'s subjective manifestations include difficulty recalling the names of family members and remembering his room number. He has trouble repeating what he just read and experiences rapid mood swings. He is agitated and aggressive, and also appears fearful. He has shown an increased tendency to wander at night and frequently gets lost. He is also dependent on assistance for many Activities of Daily Living (ADLs), including dressing, bathing, and feeding.
The objective manifestations include a WBC count of 19.2 (1,000/uL), which is elevated, and urinalysis results positive for a moderate amount of leukocytes with cloudy appearance. His vital signs are within normal range, and his physical parameters are unremarkable. The CT scan of the head shows no changes from the previous scan.
