If a patient comes in to the hospital for an OB check with heart rate in 115-120's consistently, do you need the patient's consent to send urine sample for tox screen? Pt was scared and complaining of ABD pain. OB patients always give sample every visit to dip anyway so can you just tell them after they give you a sample that you're going to send it to the lab for a tox screen and U/A? As an OB nurse, what would you do in this situation. I'm a student. Thanks.
