A nurse is caring for a client who has a prescription for atorvastatin. Which of the following client conditions is a contraindication to this medication?

A.

A. Auscultating the client's left arm for a bruit helps assess the patency and function of the arteriovenous fistula. A bruit indicates normal blood flow through the fistula.

B. Comparing blood pressure in both arms every 2 hours is not specifically related to monitoring the arteriovenous fistula. Blood pressure comparison may be done periodically but is not as directly relevant to postoperative care of the fistula.

C. Instructing the client to keep the left arm in a dependent position may help with venous return but is not the primary action for monitoring the arteriovenous fistula's patency and function.

D. Encouraging the client to restrict movement of the left arm is not necessary unless there are specific instructions from the surgeon. Encouraging gentle movement and range of motion exercises may actually be beneficial for preventing stiffness and promoting healing.

A. While hydrogen peroxide has some disinfectant properties, it is not as effective as other agents like chlorine bleach for cleaning surfaces contaminated with blood.

B. Isopropyl alcohol is effective against many pathogens but may not be as effective as chlorine bleach specifically for bloodborne pathogens.

C. Chlorine bleach is an effective agent for cleaning surfaces contaminated with blood and other bodily fluids, as it has strong disinfectant properties.

D. Chlorhexidine is primarily used as an antiseptic for skin preparation and may not be as effective for surface cleaning of blood contamination.
