Chapter 47: Drugs for Gastrointestinal Tract Disorders

1. A patient who experiences motion sickness when flying asks the nurse the best time to take the
medication prescribed to prevent motion sickness for a 0900 flight. The nurse will instruct the
patient to take the medication at which time?
a. As needed, at the first sign of nausea
b. At 0700, before leaving for the airport
c. At 0830, just prior to boarding the plane
d. When seated, just prior to takeoff
ANS: C
Motion sickness medication has its onset in 30 minutes. The patient should be instructed to take
the medication a half hour prior to takeoff. It is not used as needed.

2. The nurse is caring for a patient who has unexplained, recurrent vomiting and who is unable to
keep anything down. Until the cause of the vomiting is determined, the nurse will anticipate
administering which medications?
a. Antibiotics and antiemetics
b. Intravenous fluids and electrolytes
c. Non-prescription antiemetics
d. Prescription antiemetics
ANS: B
Antiemetics can mask the underlying cause of vomiting and should not be used until the cause is
determined unless vomiting is so severe that dehydration and electrolyte imbalance occurs.
Nonpharmacologic measures, such as fluid and electrolyte replacement, should be used.
Antibiotics are only used if an infectious cause is determined.

3. The parent of an 18-month-old toddler calls the clinic to report that the child has vomited 5
times that day. The nurse determines that the child has had three wet diapers in the past 6 hours.
What will the nurse recommend for this child?
a. Administering an OTC antiemetic medication such as diphenhydramine
b. Giving frequent, small amounts of Pedialyte
c. Keeping the child NPO until vomiting subsides
d. Taking the child to the emergency department for IV fluids
ANS: B
The child is not dehydrated as evidenced by adequate wet diapers, so nonpharmacologic
measures, such as oral fluids, are recommended. Antiemetics are not recommended unless
dehydration occurs. Intravenous fluids are given when dehydration is present.

4. The nurse is teaching a patient who is about to take a long car trip about using dimenhydrinate
(Dramamine) to prevent motion sickness. What information is important to include when
teaching this patient?
a. “Do not drive while taking this medication.”
b. “Dry mouth is a sign of toxicity with this mediation.”
c. “Take the medication 1 to 2 hours prior to beginning the trip.”
d. “Take 100 mg up to 6 times daily for best effect.”

,ANS: A
Drowsiness is a common side effect of dimenhydrinate, so patients should be cautioned against
driving while taking this drug. Dry mouth is a common side effect and not a sign of toxicity. The
drug should be taken 30 minutes prior to travel. The maximum recommended dose is 400 mg per
day.

5. The nurse is caring for a patient who has postoperative nausea and vomiting. The surgeon has
ordered promethazine HCl (Phenergan). Which aspect of this patient’s health history would be of
concern?
a. Asthma
b. Diabetes
c. GERD
d. Glaucoma
ANS: D
Promethazine is contraindicated in patients with glaucoma since it is an anticholinergic
medication. It should be used with caution in patients with asthma. The other two conditions are
not concerning with this medication.

6. The nurse is teaching a group of nursing students about the use of antipsychotic drugs for
antiemetic purposes. The nurse will explain that, when given as antiemetics, these drugs are
given
a. in smaller doses.
b. less frequently.
c. with anticholinergics.
d. with antihistamines.
ANS: A
Antipsychotic medications have antiemetic properties in smaller doses.

and vomiting. The nurse will tell the patient that this drug will be given at which time?
a. Before and after the chemotherapy
b. During chemotherapy
c. Immediately prior to chemotherapy
d. 24 hours prior to chemotherapy
ANS: A
Cannabinoids are given prior to chemotherapy and for 24 hours after chemotherapy.

8. A woman who is 2 months pregnant reports having morning sickness every day and asks if she
can take any medications to treat this problem. The nurse will recommend that the patient take
which action first?
a. Contact the provider to discuss a possible need for intravenous fluids.
b. Contact the provider to discuss a prescription antiemetic.
c. Use nonpharmacologic measures such as saltines.
d. Take over-the-counter antiemetics such as diphenhydramine.
ANS: C
Pregnant women should avoid antiemetics during the first trimester of pregnancy because of

, possible teratogenic effects. The nurse should recommend nonpharmacologic measures such as
saltines. If this is not effective, intravenous fluids may become necessary. Pregnant women
should consult with their provider before taking prescription or over-the-counter antiemetics.

9. The parent of a child who is receiving chemotherapy asks the nurse why metoclopramide
(Reglan) is not being used to suppress vomiting. The nurse will explain that, in children, this
drug is more likely to cause which effect?
a. Excess sedation
b. Extrapyramidal symptoms
c. Paralytic ileus
d. Vertigo
ANS: B
Metoclopramide can cause extrapyramidal symptoms, and these effects are more likely in
children. Children are not more prone to sedative effects, paralytic ileus, or vertigo while taking
this drug.

10. The child who is a candidate for treatment with syrup of ipecac after ingestion of a toxic
substance or overdose is the child who has ingested which substance?
a. Acetaminophen elixir
b. Chlorine bleach
c. Kerosene
d. Toilet cleanser
ANS: A
Ipecac should not be given to patients who have ingested caustic substances or petroleum
distillates since regurgitation carries a risk of aspiration. Acetaminophen is not a caustic
substance or a petroleum distillate. Chlorine bleach and toilet cleanser are caustic substances.
Kerosene is a petroleum distillate.

11. The nurse is teaching a group of parents about the use of syrup of ipecac. Which instruction
will the nurse provide?
a. “Do not administer ipecac without consulting a poison control center.”
b. “Expect the onset of emesis to be immediate.”
c. “Give ipecac with a glass of milk to increase its emetic effect.”
d. “Use ipecac fluid extract and not ipecac syrup.”
ANS: A
Ipecac should not be used for caustic substances or petroleum distillates. Ipecac should be given
only after determining whether it is safe. The onset of emesis is in 15 to 30 minutes. Ipecac
should not be given with milk or carbonated beverages. Ipecac syrup should be used.

12. A patient asks the nurse about using loperamide (Imodium) to treat infectious diarrhea.
Which response will the nurse give?
a. “Loperamide results in many central nervous system (CNS) side effects.”
b. “Loperamide has no effect on infectious diarrhea.”
