Which of the following actions could expose the nurse to malpractice issues?

Administering potassium via IV bolus can expose a nurse to malpractice issues due to the potential for serious complications associated with this action. Potassium infusion requires careful consideration of several factors, including the patient's current potassium levels, renal function, and overall cardiovascular status. Administering potassium too quickly or inappropriately can lead to hyperkalemia, which can result in life-threatening cardiac arrhythmias.

Proper protocols and guidelines mandate that potassium should typically be administered as a slow infusion rather than as a bolus to minimize the risk of adverse effects. Failure to adhere to these protocols could be seen as a breach of the standard of care, potentially leading to legal ramifications if a patient suffers harm as a result. Hence, this action poses a significant risk for malpractice issues, as it may lead to serious patient harm if not performed with proper caution and within established guidelines.
