Emergency Testing and Treatment in One Location
In an emergency, the right diagnosis guides the right treatment. Our physicians begin with your symptoms, medical history and physical exam, then order appropriate testing when it can help clarify what is happening. Because core emergency imaging and laboratory capabilities are available on site, your care team can move from assessment to results and physician-directed treatment without sending you to multiple offices. The tests you receive depend on your individual medical needs.

About MRI
NorthStar's confirmed on-site imaging capabilities are multi-slice CT, digital X-ray and bedside ultrasound. We do not claim on-site MRI availability.

The safest imaging choice is determined by your physician after evaluating your symptoms and medical history.
Physician-Directed Care
IV Fluids and Dehydration Treatment
Vomiting, diarrhea, fever, heat exposure and difficulty keeping fluids down can lead to dehydration. After assessing your condition, a physician may recommend oral hydration, IV fluids, medication, laboratory testing or monitoring.
Possible dehydration symptoms include intense thirst, dry mouth, dizziness, weakness, reduced urination, fast heart rate or confusion. Severe symptoms warrant urgent evaluation.
Important distinction: Emergency IV hydration is not an iron-infusion program. NorthStar does not advertise elective iron infusions on this page.
Treatment Follows the Diagnosis
Depending on the evaluation, emergency treatment may include:
- IV hydration and physician-ordered medication
- Pain, nausea or fever management
- Monitoring and repeat assessment
- Injury, wound or symptom-specific care
- Discharge guidance, referral or transfer when needed
