Question 1 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 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
Rationale: Insulin is commonly administered subcutaneously for routine management and intravenously in emergencies like diabetic ketoacidosis. Intradermal, oral, and topical routes are ineffective due to poor absorption or degradation.
Question 4 of 5
Which of the following complaints by a man taking gentamycin would be most indicative that he is experiencing ototoxicity?
Correct Answer: A
Rationale: Gentamicin, an aminoglycoside, can cause ototoxicity, leading to hearing loss or tinnitus. Difficulty hearing the television directly indicates auditory impairment. Tingling suggests neuropathy, BUN/creatinine elevation indicates nephrotoxicity, and mental status changes are nonspecific.
Question 5 of 5
The patient with tuberculosis is now on isoniazid (INH). Which laboratory test should the nurse monitor?
Correct Answer: A
Rationale: Isoniazid is hepatotoxic, potentially causing liver damage, so monitoring liver function tests (LFTs) is essential to detect early hepatotoxicity. PT/PTT (clotting), BUN (kidney), and CBC (general health) are not primarily affected by INH.
