important nursing consideration when administering this medication?
Monitor trough levels to prevent toxicity.
2. A nurse is administering gentamicin to a patient. Which assessment is crucial to monitor for
toxicity?
Hearing and renal function, as gentamicin can cause ototoxicity and nephrotoxicity.
3. Which antibiotic is associated with a high risk of tendon rupture, especially in older adults?
Fluoroquinolones
4. A patient has been prescribed isoniazid for latent tuberculosis. The nurse should recommend
which supplement to prevent neuropathy?
Vitamin B6 (pyridoxine)
5. A nurse is educating a patient about metronidazole for a bacterial infection. What should the

,6. For patients with a known deficiency in G6PD, which class of drugs should be avoided due to
the risk of hemolysis?
Sulfonamides
7. A patient is prescribed clopidogrel. Genetic testing reveals the patient is a poor metabolizer of
CYP2C19. How might this impact therapy?
The patient may not effectively convert clopidogrel into its active form, reducing its
efficacy.

affect the drug's metabolism and efficacy?
CYP2D6

genetic deficiency?
