The nurse is most concerned about which of these findings in a client with systemic lupus erythematosus (SLE)?

Choice A reason: Obtaining a PAPR mask is not a step in preparing a sterile field. A PAPR mask is a powered airpurifying respirator that protects the wearer from airborne contaminants. It is not required for setting up a sterile field, unless the client has a highly infectious disease.

Choice B reason: Do not turn away from the sterile field is a step in preparing a sterile field. Turning away from the sterile field can contaminate the field or the items on it. The nurse should always face the sterile field and keep it in view.

Choice C reason: Add items to the sterile field by dropping them gently is a step in preparing a sterile field. Dropping items gently onto the sterile field prevents splashing or touching the field or the items. The nurse should open the sterile packages away from the field and drop the items close to the edge of the field.

Choice D reason: Covering the sterile field once it is set up is not a step in preparing a sterile field. Covering the sterile field can compromise its sterility and create moisture that can harbor microorganisms. The nurse should not cover the sterile field unless it is necessary to move it or store it for later use.

Choice E reason: Preparing the client before setting up the sterile field is a step in preparing a sterile field. Preparing the client involves explaining the procedure, obtaining consent, providing privacy, and positioning the client. The nurse should prepare the client before setting up the sterile field to avoid leaving the field unattended or exposing it to the client's body fluids.

Choice A reason: Truck driver is not an occupation that increases the risk for carpal tunnel syndrome, because it does not involve repetitive or forceful flexion or extension of the wrist. Carpal tunnel syndrome is a condition that occurs when the median nerve, which runs through the carpal tunnel in the wrist, is compressed or irritated by inflammation, swelling, or pressure. Truck drivers may experience other musculoskeletal problems, such as back pain, neck pain, or shoulder pain, due to prolonged sitting, vibration, or poor posture.

Choice B reason: Nursing assistant is an occupation that increases the risk for carpal tunnel syndrome, but it is not the best answer, because it involves other factors besides repetitive motion that can contribute to the condition. Nursing assistants may perform repetitive tasks, such as lifting, transferring, or bathing patients, that can strain the wrist and the median nerve. However, they may also experience other risk factors, such as trauma, infection, arthritis, or pregnancy, that can cause carpal tunnel syndrome.

Choice C reason: Elementary school teacher is not an occupation that increases the risk for carpal tunnel syndrome, because it does not involve repetitive or forceful flexion or extension of the wrist. Elementary school teachers may perform some tasks, such as writing, typing, or grading papers, that can involve wrist movement, but they are not likely to be frequent or intense enough to cause carpal tunnel syndrome. Elementary school teachers may experience other stressrelated problems, such as headaches, fatigue, or burnout, due to the demands of their work.

Choice D reason: Assembly line worker is the best answer, because it is an occupation that increases the risk for carpal tunnel syndrome, due to the nature and duration of the work. Assembly line workers may perform repetitive, forceful, or awkward movements of the wrist, such as twisting, bending, or gripping, that can cause compression or irritation of the median nerve. Assembly line workers may also work for long hours, with little rest or variation, that can exacerbate the condition.
