B. Stimulation of serotonin receptors found in the vestibular apparatus causes nausea and vomiting
C. The chemoreceptor trigger zone is protected from blood-borne toxins by the blood/brain barrier making chemotherapy-induced nausea and vomiting rare
D. Visceral vagal nerve fibers are rich in serotonin receptors and respond to GI distention and mucosal irritation, which contribute to nausea and vomiting
D
Option D: Correct. Visceral vagal nerve fibers are rich in serotonin receptors and result in nausea and vomiting in response to GI distention and mucosal irritation.

C. Salivation, constipation, insomnia
D. Dry mouth, diarrhea, drowsiness
B
- Which of the following adverse effects is associated with promethazine administered intra-arterially?

intra-arterially.
- A 57-year-old obese woman is scheduled to undergo lengthy abdominal surgery. She smokes one pack of cigarettes per day, does not drink alcohol, and has a history of motion sickness. Which set of risk factors predisposes this patient to postoperative nausea and vomiting (PONV)?
A. Female sex, smoking history, and alcohol history
B. Body habitus, history of motion sickness, and alcohol history
C. Female sex, history of motion sickness, and duration of surgery
D. Body habitus, smoking history, and alcohol history
C

- Which one of the following is an appropriate nonpharmacologic treatment option for motion sickness?
A. Increasing exposure to movement to acclimate to it more quickly
B. Reading in a moving vehicle to distract from the motion
C. Placing the head between the knees to reduce visual stimulation

- Which of the following statements about netupitant is true?
A. It is renally eliminated
B. It is free of CYP 450–mediated drug interactions
C. It is only available as a combination product with palonosetron
D. It is ineffective for CINV prophylaxis when used with standard antiemetics
C
Option A: Incorrect. Netupitant is primarily eliminated via hepatic and biliary clearance.
Option B: Incorrect. Like the NK-1 receptor antagonist aprepitant, netupitant interacts with substrates of the CYP P450 system. Rolapitant is the NK-1 receptor antagonist free from CYP 450–mediated drug interactions.
Option C: Correct. Netupitant is only available as a combination product with the 5-HT 3 receptor antagonist palonosetron.
Option D: Incorrect. Netupitant and the other NK-1 receptor antagonists are effective and recommended for preventing acute and delayed CINV when used with other antiemetics.
- A 40-year-old man is experiencing acute nausea and vomiting due to gastroenteritis. He has had these symptoms for approximately 12 hours and has not been able to keep any food or drink down during that time. You classify his symptoms as simple nausea and vomiting. Which monitoring parameters are the most appropriate for this patient’s symptoms?
A. Check blood urea nitrogen (BUN) and serum creatinine (SCr) to evaluate hydration status
B. Weigh the patient to determine whether he has lost weight due to his symptoms
C. Assess for dry mucous membranes or skin tenting to assess hydration status
D. Check serum electrolyte concentrations to evaluate and correct electrolyte imbalances
C
Option C: Correct. This patient’s nausea and vomiting is simple, acute nausea and vomiting and will likely resolve without significant interventions. It is reasonable to ask the patient about number and volume of vomiting episodes and assess for dehydration using simple physical assessments such as dry mucous membranes and skin tenting.
- A 73-year-old woman is going on a 7-day cruise. She has a history of car sickness on long trips. Her past medical history is significant for overactive bladder for which she takes oxybutynin 10 mg XR once daily. She is worried about motion sickness ruining her trip and asks what you recommend. Which one of the following options is the best recommendation?
A. Apply a transdermal scopolamine patch 1 hour before the trip
B. Apply acupressure wrist bands for the duration of the cruise
C. Take aprepitant 40 mg orally if nausea or vomiting occurs
D. Take meclizine 50 mg orally if nausea or vomiting occurs
B
Option A: Incorrect. Although anticholinergics and antihistamines are generally first-line therapy
for motion sickness, this patient’s age and history of anticholinergic therapy for overactive bladder make the anticholinergic side effects associated with these therapies undesirable.
Option B: Correct. Initiating a nonpharmacologic approach such as acupressure wrist bands is
effective and safer than pharmacologic therapy with anticholinergic adverse effects for this patient.
Option C: Incorrect. If aprepitant is used, it should be provided prior to exposure to motion to prevent motion sickness.
Option D: Incorrect. Meclizine has anticholinergic adverse effects.
- A 26-year-old woman in her first trimester of pregnancy (week 9) is experiencing severe nausea and vomiting that is interfering with her ability to maintain an acceptable level of nutrition. Which one of the following antiemetic regimens would be the most appropriate?
A. Dronabinol 5 to 15 mg/m 2 every 2 to 4 hours as needed
B. Droperidol 0.625 mg orally every 12 hours as needed
C. Doxylamine 10 mg/pyridoxine 10 mg, 2 tablets at bedtime
D. Dolasetron 100 mg orally every 8 hours as needed
C
Option A: Incorrect. Dronabinol is mainly used as an adjunctive agent for treating CINV and not routinely used to treat NVP.
Option B: Incorrect. Droperidol is primarily used to prevent or treat PONV and not NVP.
Option C: Correct. Doxylamine and pyridoxine are considered first line for moderate to severe NVP.
Option D: Incorrect. The 5HT 3 antagonists may be considered for treating NVP after patients have failed initial therapy with first-line agents such as doxylamine and pyridoxine.
