A college student with migraine headaches that cause nausea and vomiting has been prescribed trimethobenzamide.
The nurse should caution the student to avoid using which substance?
St. John’s wort.
Alcohol.
Calcium channel blockers.
Selective serotonin reuptake inhibitors (SSRIs).
The Correct Answer is B
The nurse should caution the student to avoid using alcohol with trimethobenzamide because this combination can cause side effects such as drowsiness, dizziness, and impaired reactions. Alcohol can also worsen the symptoms of nausea and vomiting.
Choice A is wrong because St.
John’s wort is a herbal supplement that is used to treat depression and anxiety.
It does not interact with trimethobenzamide.
Choice C is wrong because calcium channel blockers are a class of medications that are used to treat high blood pressure and heart problems.
They do not interact with trimethobenzamide.
Choice D is wrong because selective serotonin reuptake inhibitors (SSRIs) are a class of medications that are used to treat depression and anxiety.
They do not interact with trimethobenzamide.
Trimethobenzamide is an antihistamine that works by blocking the D receptor in the brain and suppressing the chemoreceptor trigger zone that causes nausea and vomiting.
It is available as an oral capsule or an intramuscular injection.
It can cause side effects such as skin rash, tremors, parkinsonism, and jaundice.
It should not be used in children or people with liver or kidney disease.

Correct Answer is A
Explanation
The nurse should ask this question because the client is taking a chemical stimulant laxative, which can cause dehydration and electrolyte imbalance, especially in combination with medications for heart failure and osteoarthritis that may also affect fluid and electrolyte balance. The nurse should assess the client’s hydration status and risk of hypovolemia or hypotension.
Choice B. Timing of medication administration is wrong because it is not the priority question in this situation.
The nurse should ask this question later to determine if the client is taking the medications as prescribed and if there are any drug interactions or adverse effects.
Choice C. Previous effectiveness of laxatives is wrong because it is not relevant to the client’s current condition.
The nurse should ask this question later to evaluate the client’s bowel habits and history of constipation.
Choice D. The amount of fiber intake is wrong because it is not the priority question in this situation.
The nurse should ask this question later to educate the client about dietary measures to prevent constipation and promote bowel health.
Correct Answer is C
Explanation
This statement indicates that the patient understands the common side effect of codeine and how to prevent accidents while taking it.
Choice A is wrong because the patient should not take the medication anytime he starts to cough, but only as prescribed by the doctor.
Taking too much codeine can lead to overdose, addiction, or respiratory depression.
Choice B is wrong because this medication may not make the patient anxious and nervous, but rather sedated and relaxed.
Anxiety and nervousness are more likely to occur with decongestants, which are stimulants.
Choice D is wrong because diarrhea is not a common side effect of codeine.
In fact, codeine may cause constipation, so the patient should increase fluid and fiber intake while taking it.
