Final answer:
The nurse should contact the provider for urine culture and sensitivity testing if the elderly patient with worsening dementia exhibits fever and dysuria.
Step-by-step explanation:
The nurse should contact the provider to obtain an order for urine culture and sensitivity testing based on the following assessment findings:
- Worsening dementia: The decline in mental function in an elderly patient can be a sign of a urinary tract infection (UTI) in this population.
- Fever: A sudden onset of fever can indicate an infection, including a UTI.
- Dysuria: Pain or discomfort during urination is a common symptom of a UTI.
Obtaining a urine sample for culture and sensitivity testing is important to confirm the presence of infection and identify the causative agent, guiding appropriate antibiotic treatment.
