The client with severe otitis media and mastoiditis is prescribed levofloxacin IV, 250 mg every 12 hours. The medication is diluted in 100 mL of NS. To deliver the antibiotic in 30 minutes, the nurse must infuse the solution at a rate of how many mL per hour?
- A. 200
Correct Answer: A
Rationale: The rate of IV infusion is calculated as follows: 100 mL over 30 minutes equals X mL over 60 minutes. Thus, 100/30 = X/60, so X = (100 × 60) / 30 = 200 mL/hr.
The elderly male client tells the nurse, 'My wife says her cooking hasn't changed, but it is bland and tasteless.' Which response by the nurse is most appropriate?
- A. Would you like me to talk to your wife about her cooking?
- B. Taste buds change with age, which may be why the food seems bland.
- C. This happens because the medications sometimes cause a change in taste.
- D. Why don't you barbecue food on a grill if you don't like your wife's cooking?
Correct Answer: B
