Question 1 of 5
Which class of antibiotic is associated with cartilage toxicity and rupture of the Achilles tendon?
Correct Answer: A
Rationale: Fluoroquinolones (e.g., ciprofloxacin) are linked to tendonitis and Achilles tendon rupture, particularly in older adults or with corticosteroid use, due to effects on connective tissue. Other classes listed do not have this association.
Question 2 of 5
Children younger than 9 years should not be given tetracyclines because:
Correct Answer: D
Rationale: Tetracyclines deposit in developing teeth, causing permanent discoloration in children under 9. They can also affect bone growth, but tooth discoloration is the primary concern. Dehydration and photosensitivity are not age-specific tetracycline issues.
Question 3 of 5
By which routes can insulin be administered? (Select All that Apply.)
Correct Answer: A,D

Question 4 of 5
The nurse is discussing treatment for a superinfection with a client and family members. The family asks the nurse what a superinfection is. What is the best response by the nurse?
Correct Answer: D
Rationale: A superinfection occurs when antibiotics kill normal flora, allowing other microbes to overgrow, causing a new infection. Drug resistance, immune weakness, or treatment difficulty are not specific to superinfections.
Question 5 of 5
The nurse is caring for a client with a diagnosis of urinary tract infection. The physician has ordered an antibiotic. What is the priority prior to administering this medication?
Correct Answer: C
Rationale: A urine culture and sensitivity test identifies the causative bacteria and effective antibiotics, ensuring targeted treatment. Platelet count, blood pressure, and PTT are not priorities for UTI antibiotic administration.
