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.

Explanation
Hypercalcemia is a condition caused by having too much calcium in the blood, which can affect the function of nerves, muscles, kidneys and heart. Hypercalcemia can occur in children due to various causes, both acquired and genetic. One of the most common causes of hypercalcemia in children is cancer, especially cancers that affect the bones or produce substances that mimic parathyroid hormone (PTH), which regulates calcium levels.
Choice A is wrong because liver failure does not directly cause hypercalcemia, although it can affect vitamin D metabolism and calcium absorption.
Choice B is wrong because radiation injury does not cause hypercalcemia, unless it damages the parathyroid glands or causes bone destruction.
Choice D is wrong because hypothyroidism does not cause hypercalcemia, although it can affect bone turnover and calcium excretion.
