ATI TEAS (Test of Essential Academic Skills) Version 7ReadingHard
A patient is given a prescription for a new medication. The pharmacist explains, 'Take one tablet by mouth twice daily, preferably with food, for 10 days. Do not crush or chew the tablet. If you miss a dose, take it as soon as you remember, unless it's almost time for your next dose; in that case, skip the missed dose and continue your regular schedule. Do not take two doses at once.' What is the most critical piece of information for preventing potential harm to the patient?
- ANot crushing or chewing the tablet.
- BTaking the medication with food.
- CThe duration of the medication course.
- DThe instructions for a missed dose.
Show answer & explanationAnswer & explanation
Correct answer: A. Not crushing or chewing the tablet.
Not crushing or chewing the tablet is critical because altered administration can destroy an enteric coating, lead to rapid absorption of a sustained-release drug, or cause local irritation, potentially resulting in overdose, reduced efficacy, or severe side effects. This directly prevents harm.
Why the other options are wrong
- B. Taking with food helps reduce gastrointestinal upset or improve absorption but usually doesn't prevent direct harm if omitted.
- C. The duration is important for treatment efficacy, but incorrectly ending the course doesn't typically cause immediate harm as severe as improper administration.
- D. Missed dose instructions prevent accidental double dosing, but crushing/chewing can lead to a more immediate and severe adverse event due to altered pharmacokinetics.
Critical Medication Instructions
Critical medication instructions are those that, if not followed precisely, can lead to significant patient harm, such as overdose, severe side effects, or complete loss of drug efficacy, often due to altered pharmacokinetics.
- Instructions regarding crushing/chewing are often due to extended-release formulations or enteric coatings.
- Altering these can lead to 'dose dumping' or drug degradation.
- These instructions directly impact drug absorption and concentration.
- Failure to follow can result in immediate adverse reactions.
Memory trick: Harm prevention is priority one, beyond comfort or completion.
