The nurse is caring for a client who is scheduled to have a liver biopsy. Before the procedure, it is important for the nurse to assess which parameter to assure client safety?

A liver biopsy is an invasive procedure that involves inserting a needle into the liver to obtain a tissue sample. To ensure client safety, the nurse must assess the client's ability to lie still and hold their breath during the procedure, as movement or breathing can cause complications such as bleeding or injury to surrounding organs. Assessing pain tolerance, allergies to iodine or shellfish, or a history of nausea and vomiting is not directly related to the safety of the liver biopsy procedure.
