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).

Answer and Explanation

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 C

Explanation

This is because cortisol exhibits a proper 24-h circadian rhythm that affects the cardiovascular system and other organs. Cortisol levels are normally low at the beginning of sleep and high at the moment of awakening. Taking corticosteroids at this time mimics the natural cortisol rhythm and may reduce side effects such as adrenal suppression, sleep disturbances and cardiovascular complications.

Choice A is wrong because taking corticosteroids at 08:00 may not coincide with the client’s natural cortisol peak and may cause insomnia or unpleasant dreams.

Choice B is wrong because taking corticosteroids at 22:00 may disrupt the client’s sleep quality and increase the risk of nocturnal hypertension.

Choice D is wrong because taking corticosteroids at 16:00 may interfere with the client’s natural cortisol decline and cause hyperglycemia or dyslipidemia.

A. Abdominal pain. B. Tinnitus. C. Alteration in consciousness. D. Changes in vision.

Correct Answer is A

Explanation

Octreotide is a synthetic analog of somatostatin, a hormone that inhibits the secretion of growth hormone, insulin, glucagon, and other hormones. Octreotide can cause gastrointestinal side effects such as abdominal pain, diarrhea, constipation, nausea, vomiting, and flatulence. These side effects are more common and severe with the oral route than with the injectable route.

Choice B is wrong because tinnitus, or ringing in the ears, is not a common or serious side effect of octreotide.

Choice C is wrong because alteration in consciousness is not a common or serious side effect of octreotide.

However, octreotide can affect blood glucose levels and cause hypoglycemia or hyperglycemia, which can lead to confusion, dizziness, fainting, seizures, or coma in severe cases.

Choice D is wrong because changes in vision are not a common or serious side effect of octreotide.

However, octreotide can cause rare but serious eye problems such as blurred vision, double vision, eye pain, or blindness due to optic nerve damage or retinal detachment.

These eye problems require immediate medical attention.

Normal ranges for blood glucose are 70 to 100 mg/dL (3.9 to 5.6 mmol/L) for fasting and less than 140 mg/dL (7.8 mmol/L) for postprandial.
