A nurse is preparing to administer mannitol 0.2 g/kg IV bolus over 5 min as a test dose to a client who has severe oliguria. The client weighs 198 lb. What is the amount in grams the nurse should administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

- A. Incorrect. The nurse should check the functioning of oxygen equipment daily, not weekly, to ensure safety and proper delivery of oxygen.

- B. Correct. The nurse should instruct the client to wear clothing made with cotton fabrics while oxygen is in use, as synthetic fabrics can generate static electricity and cause sparks that could ignite the oxygen.

- C. Incorrect. The nurse should instruct the client to avoid petroleum-based lubricants, such as Vaseline, as they are flammable and could cause burns if exposed to oxygen. The nurse should recommend water-soluble lubricants, such as K-Y jelly, instead.

- D. Incorrect. The nurse should instruct the client to store full oxygen tanks upright, not on their side, to prevent them from rolling and damaging the valve or regulator.

A: Incorrect. Aspirin can trigger asthma attacks in some children and should be avoided.

B: Incorrect. The peak expiratory flow meter should be used daily, not just when the child has symptoms, and the highest reading should be recorded, not the average.

C: Incorrect. Carpet can harbor dust mites, mold, and other allergens that can worsen asthma. It is better to have hardwood or tile floors and washable rugs.

D: Correct. Influenza immunization can prevent serious complications from respiratory infections in children with asthma.
