Here, where a patient removed the tube herself and refused replacement, important questions about the procedures, protocols, and duties of a licensed nurse in these circumstances must be explained in order to establish a deviation in the standard of care. In addition, important considerations about patient autonomy complicate the standard-of-care analysis. A jury could not reach a determination as to a nurse’s responsibility under these circumstances without the benefit of expert opinion as to the appropriate balance between patient autonomy and prescribed treatment. An affidavit of merit was therefore required.
