How much does Rn cost?

Answer 1

Answer 2

The cost of hiring a Registered Nurse (RN) can vary depending on location, experience, and employer. On average, hourly rates for RNs range from $25 to $45, with additional costs for benefits and overtime. Employers may also offer salary packages instead of hourly rates.
