North Dakota Med Spa Owner Arrested After Allegedly Posing as Nurse and Performing IV as Patient’s Hand Turned Purple
WATFORD CITY, NORTH DAKOTA — The owner of a North Dakota medical spa is facing multiple criminal charges after police say she posed as a licensed nurse, performed medical procedures without proper credentials, and recklessly endangered a patient during an IV treatment that caused the patient’s hand to turn purple.
Investigation Launched After Complaints
Kendra Cain, owner of Royals Medical Spa, was arrested Sunday following an investigation by the Watford City Police Department, according to reporting by the McKenzie County Farmer.
Police said Cain did not possess any medical or nursing license, despite advertising and performing medical procedures at the spa. Investigators allege Cain used one of her employee’s professional licenses to schedule patients, prescribe medications, and carry out treatments that legally require licensed medical personnel.
Royals Medical Spa reportedly opened in September 2025 and abruptly closed on Jan. 22 amid mounting complaints.
Nurse Patient Raises Alarm
One of the key complaints came from a registered nurse who was herself a patient at the spa, police said.
According to investigators, the nurse told officers that during an IV treatment, she had to coach Cain on how to insert the IV, raising immediate concerns about Cain’s qualifications.
The patient said Cain allegedly left a tourniquet on her arm for too long, causing her hand to turn purple during the procedure.
Air Spotted in IV Tube Raised Life-Threatening Concern
The nurse patient further told police that she observed air inside the IV tubing, a dangerous situation that could potentially lead to an air embolism, a condition that can cause serious injury or death.
Police noted that the patient recognized the risk because of her own medical training and reported the incident to authorities shortly afterward.
Search Warrant Reveals Concerning Conditions
When officers executed a search warrant at the med spa on Jan. 22, they found a patient treatment area containing a used IV bag, tubing, syringe, needle, bandages, and an open sharps container, police said.
Investigators also reported seeing fresh blood on the floor near the IV treatment area, further supporting concerns about unsafe medical practices inside the spa.
No Medical License on Record
Police confirmed that no records exist showing Cain ever held a nursing license or any other medical certification in North Dakota or elsewhere.
Despite this, investigators allege she represented herself as a registered nurse and continued performing invasive medical procedures.
Charges Filed, Court Date Set
Cain was arrested and charged with:
- Reckless endangerment
- Practicing as a nurse without proper certification
- Unauthorized use of personal identifying information
- Deceptive writings
She was booked into the McKenzie County Correctional Facility and later released from custody.
Cain’s next court appearance is scheduled for March 26, court records show.
Authorities Urge Patients to Verify Credentials
Police said the investigation remains ongoing and encouraged anyone who received treatment at the spa to contact law enforcement.
The case has renewed warnings from officials about the importance of verifying medical credentials, especially in rapidly growing industries like IV therapy and cosmetic wellness services.
