A nurse enters a client's room and sees smoke coming from the trash can next to the client's bed. Which of the following actions should the nurse take first?

Choice A reason: This is not an appropriate action because performing hand hygiene with hands at elbow level can contaminate or recontaminate hands by allowing water or soap to drip from elbows to hands or wrists. The nurse should perform hand hygiene with hands lower than elbows and avoid touching faucets or sinks with hands or forearms.

Choice B reason: This is an appropriate action because cleaning a blood spill with chlorine bleach can disinfect and decontaminate surfaces that have been exposed to bloodborne pathogens, such as hepatitis B virus or human immunodeficiency virus. The nurse should wear gloves and use a 1:10 dilution of bleach and water to clean the spill.

Choice C reason: This is not an appropriate action because instructing a female client to wipe her perineal area from back to front can increase the risk of urinary tract infection or vaginal infection by introducing bacteria from the anus to the urethra or vagina. The nurse should instruct the client to wipe her perineal area from front to back and use a clean tissue for each wipe.

Choice D reason: This is not an appropriate action because rolling soiled linen with clean side in before placing it in laundry bag can spread microorganisms or body fluids to hands, clothing, or environment. The nurse should fold or roll soiled linen with dirty side in and avoid shaking or tossing it.

Choice A reason: This is not a food that the nurse should recommend because oatmeal is high in fiber and phytates, which are compounds that can bind to iron and reduce its absorption in the gastrointestinal tract. The nurse should advise the client to avoid consuming foods high in fiber or phytates within 2 hours before or after taking ferrous sulfate.

Choice B reason: This is a food that the nurse should recommend because raw oranges are high in vitamin C, which is an antioxidant that can enhance iron absorption by reducing it to its more soluble form. The nurse should advise the client to consume foods high in vitamin C, such as citrus fruits, tomatoes, or peppers, along with ferrous sulfate.

Choice C reason: This is not a food that the nurse should recommend because cheese is high in calcium and casein, which are substances that can interfere with iron absorption by forming insoluble complexes with it. The nurse should advise the client to avoid consuming foods high in calcium or casein, such as dairy products, eggs, or soybeans, within 2 hours before or after taking ferrous sulfate.

Choice D reason: This is not a food that the nurse should recommend because baked potatoes are high in starch and oxalates, which are compounds that can inhibit iron absorption by forming insoluble salts with it. The nurse should advise the client to avoid consuming foods high in starch or oxalates, such as potatoes, spinach, or rhubarb, within 2 hours before or after taking ferrous sulfate.
