75. Which of the following prescription instructions should be considered an abnormal dose?
Answer: D
Zolpidem 10 mg: 1 tab PO q.a.m. is considered an abnormal dose.
Zolpidem is typically prescribed as a sleep aid that should be taken at bedtime, making the instruction to take it in the morning (q.a.m.) abnormal and potentially unsafe.
A) Pantoprazole 40 mg: 1 tab PO daily
This dosage for Pantoprazole, a proton pump inhibitor used to treat gastroesophageal reflux disease (GERD), is standard and widely accepted. A dose of 40 mg once daily is within the typical prescribing guidelines.
B) Ciprofloxacin 500 mg: 1 tab PO b.i.d.
Ciprofloxacin, a fluoroquinolone antibiotic, is often prescribed at a dosage of 500 mg taken twice daily (b.i.d.) for various infections. This dosage aligns with common medical practices and therefore is not considered abnormal.
C) Rosuvastatin 40 mg: 1 tab PO q.h.s.
Rosuvastatin is a statin medication used to lower cholesterol, and a dose of 40 mg taken at bedtime (q.h.s.) is within the acceptable range for managing high cholesterol. This is a standard practice and does not represent an abnormal dose.
D) Zolpidem 10 mg: 1 tab PO q.a.m.
Zolpidem is intended for use as a sleep aid, and taking it in the morning (q.a.m.) is contrary to its intended purpose. This timing can lead to excessive sedation during the day, making this instruction abnormal and inappropriate.
Conclusion
The abnormality of the Zolpidem dosing instruction lies in its timing, as it is intended for nighttime use. All other options reflect appropriate dosages and timings for their respective medications, confirming that only the Zolpidem instruction is abnormal. Hence, D is the definitive choice.
