Which type of vomiting may a patient with hyperemesis gravidarum experience?
A. Motion sickness
B. Morning sickness
C. Psychogenic vomiting
D. Postoperative vomiting
Morning sickness
Hyperemesis gravidarum is a condition in which starvation, dehydration, and acidosis are
superimposed on the vomiting syndrome. This condition occurs in pregnant women when
severe persistent vomiting (described as morning sickness) interferes with nutrition, fluid,
and electrolyte balance. Motion sickness is nausea and vomiting associated with motion; it
is thought to result from stimulation of the ear's labyrinth system. Psychogenic vomiting can
either be self-induced or occur involuntarily in response to situations that the person
considers threatening or distasteful. Postoperative vomiting is a relatively common
complication that occurs after surgery.
Which condition is also known as dry heaves?
Retching
Dry heaves, or retching, is the involuntary labored, spasmodic contraction of the abdominal
and respiratory muscles without emesis. Nausea is a sensation of abdominal discomfort that
is intermittently accompanied by a desire to vomit. Vomiting is the forceful expulsion of
gastric contents up the esophagus and out the mouth. Regurgitation occurs when gastric or
esophageal contents rise to the pharynx because of pressure.
Which drug has a high potential for emesis when given intravenously?
, Cisplatin (Platinol-AQ) has a high potential for emesis with IV antineoplastic agents.
Paclitaxel (Taxol) has a low potential for emesis. Carboplatin (Paraplatin) and daunorubicin
(Cerubidine) have moderate potentials for emesis.
Which condition may be a cause of nausea and vomiting during pregnancy?
Obesity
Nausea and vomiting in pregnancy is commonly known as morning sickness. Vomiting is
much more common among obese women. Diabetes, thyroid disease, and gall bladder
disease do not have an effect on morning sickness.
Which type of vomiting is best treated by the anticholinergic properties of antihistamine
drugs?
The effectiveness of antihistamines in treating motion sickness results from their
anticholinergic properties, not from their ability to block histamines. A combination of
prochlorperazine (Compazine), lorazepam (Ativan), and diphenhydramine (Benadryl)
successfully controls delayed emesis. Drugs generally used to treat morning sickness include
vitamin B 6 and phenothiazines. Antihistamines may also be used but they are more
effective in treating motion sickness. Drugs used to treat anticipatory nausea and vomiting
includes benzodiazepines.
Which drug causes profound hypotension and loss of consciousness when used with
serotonin antagonists?
Apromorphine (Apokyn)
Which class of drugs may intensify postoperative nausea and vomiting (PONV)?
Analgesics are emetogenic in nature; therefore the use of these drugs may intensify PONV.
Anticholinergic agents are antiemetic agents that decrease the risk of PONV. Histamine-2
antagonists are used to reduce gastric secretions, which minimize nausea and vomiting.
Nonsteroidal antiinflammatory agents are not emetogenic; they reduce the risk of PONV by
providing pain relief.
