Final answer:
Understanding the use of levofloxacin involves knowing that avoiding exposure to direct sunlight is important due to increased skin sensitivity caused by this antibiotic.
Step-by-step explanation:
Levofloxacin is a fluoroquinolone antibiotic that is effective against a variety of bacterial infections, such as urinary tract infections (UTIs). When a woman with symptoms of urinary frequency and burning is prescribed levofloxacin, she demonstrates understanding of the medication by stating she will avoid exposure to direct sunlight. This is because fluoroquinolones can make the skin more sensitive to sunlight, leading to a higher risk of sunburn or skin reactions.
It is important for patients to follow specific guidelines while taking antibiotics to ensure effectiveness and minimize side effects. For example, taking levofloxacin with an antacid could interfere with the absorption of the medication, and increasing caffeine intake or limiting fluid intake would not be advisable adjustments during UTI treatment.
