therapeutic drug level monitoring.
True or False: Fluoroquinolones can be taken with dairy products.
False. Dairy can interfere with absorption.

Severe infections caused by Gram-negative bacteria.
Sulfonamides and Miscellaneous Antibiotics(12)
Sulfonamides are primarily used to treat?
Urinary tract infections, respiratory infections, and some gastrointestinal infections.
True or False: Sulfonamides can cause photosensitivity.
True. Nursing actions include advising patients to avoid direct sunlight and use sunscreen.

What should be monitored in patients taking sulfonamides?
Renal function and signs of hypersensitivity reactions.
What is a serious side effect of sulfonamides?
Stevens-Johnson syndrome, a potentially life-threatening skin reaction.
Fill in the blank: Sulfonamides inhibit bacterial growth by interfering with _______.
folic acid synthesis.
Compare sulfonamides and penicillins.
Sulfonamides: Bacteriostatic, inhibit folic acid. Penicillins: Bactericidal, inhibit cell wall synthesis.
Nursing action for patients on trimethoprim/sulfamethoxazole?
Encourage fluid intake to prevent crystalluria.
What are miscellaneous antibiotics?
Antibiotics not classified under major groups; examples include clindamycin and metronidazole.
Common side effects of clindamycin include?
