Correct Answer is B
Explanation
Choice A rationale
BNP is used to diagnose heart failure, not to monitor gentamicin’s adverse effects.
Choice B rationale
Creatinine levels should be monitored as gentamicin can cause nephrotoxicity, leading to impaired kidney function.
Choice C rationale
Amylase levels are not relevant for detecting gentamicin’s adverse effects.
Choice D rationale
ESR is used to detect inflammation, not specific to gentamicin’s adverse effects.
Correct Answer is D
Explanation
Choice A rationale
Taking ibandronate immediately after a meal is incorrect because food and beverages can significantly decrease the absorption of ibandronate. It should be taken on an empty stomach at least 60 minutes before any food or drink.
Choice B rationale
Drinking 8 ounces of milk when taking ibandronate is incorrect because calcium in milk can interfere with the absorption of the medication. It should be taken with plain water only.
Choice C rationale
Taking ibandronate before bedtime is incorrect because the patient needs to remain upright for at least 60 minutes after taking the medication to prevent esophageal irritation.
Choice D rationale
Taking one tablet of ibandronate on the same date each month is correct. This ensures consistent dosing and helps maintain the medication’s effectiveness.
