A client has responded poorly to conservative treatment for nausea and vomiting and has subsequently been prescribed dronabinol.
In addition to monitoring the client’s nausea, the nurse should prioritize what assessment after administering the drug?
Apical heart rate.
Blood pressure.
Mental status.
Skin integrity.
The Correct Answer is C
Dronabinol is a synthetic cannabinoid that can cause psychoactive effects such as euphoria, anxiety, hallucinations, and paranoia. The nurse should monitor the client’s mental status after administering the drug and report any changes or adverse reactions.
Choice A is wrong because dronabinol does not affect the heart rate significantly.
Choice B is wrong because dronabinol may lower or raise the blood pressure depending on the dose and the individual response, but this is not a priority assessment.
Choice D is wrong because dronabinol does not affect the skin integrity directly.

Correct Answer is C
Explanation
The CTZ has to be stimulated in order for vomiting to occur. The CTZ is located in the area postrema of the medulla oblongata and receives input from various sources, such as the blood, the vestibular system, and the gastrointestinal tract.
Choice A is wrong because the limbic system involves emotion, not vomiting or other forms of GI function.
Choice B is wrong because the hypothalamus regulates various functions such as body temperature, hunger, thirst, and circadian rhythms, but not vomiting.
Choice D is wrong because the medulla oblongata is responsible for autonomic functioning such as ventilation, cardiac conduction, and vomiting, but it is not the site of stimulation for vomiting.
The medulla oblongata contains the vomiting center, which receives signals from the CTZ and other sources and initiates the act of vomiting.
Correct Answer is B
Explanation
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.
