A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify that which of the following supplements is contraindicated for concurrent use with warfarin?

A) Elevate the extremity: This action helps reduce swelling and minimizes the spread of infiltrated fluid into surrounding tissues by using gravity to assist in draining the excess fluid back into the bloodstream. Elevating the affected limb above the level of the heart promotes venous return and can help prevent further tissue damage.

B) Flush the IV catheter: Flushing the IV catheter could exacerbate infiltration by pushing more fluid into the surrounding tissue. It is not the appropriate action for managing infiltration and could worsen the client's condition.

C) Slow the infusion rate: Slowing the infusion rate is a reasonable action to reduce the flow of fluid into the tissues and minimize further infiltration. However, it may not be sufficient to manage existing infiltration effectively or prevent tissue damage.

D) Apply pressure to the IV site: Applying pressure to the IV site is not recommended for managing infiltration. It could cause further tissue damage and discomfort for the client and is not considered a standard practice in managing this complication.

A) A client vomits after receiving an oral medication: While vomiting after medication administration should be documented in the client's medical record as it could indicate a ’otential adverse reaction or medication intolerance, it does not necessarily require an incident report unless there are unusual circumstances surrounding the event.

B) A client receives their meal tray 20 minutes before time: This situation does not require an incident report. It may be considered a minor deviation from the usual mealtime schedule, and no harm or adverse outcome is implied.

C) A client receives their insulin before scheduled time: This is the correct answer. Administering insulin before the scheduled time can pose significant risks to the client, potentially leading to hypoglycemia or other adverse effects. Such deviations from the prescribed administration time should be documented in an incident report to ensure appropriate investigation and prevention of recurrence.

D) A client experiences a seizure: While a client experiencing a seizure is a critical event that requires immediate nursing intervention and documentation, it does not typically warrant an incident report unless it occurs in unusual circumstances or if there are concerns about the client's safety or well-being during the seizur’.
