_____________Quiz____________?
The nurse is caring for a patient treated with flumazenil (Anexate) for benzodiazepine toxicity.
After administering flumazenil what will the nurse carefully assess for?
A)Agitation, confusion, and seizures
B)Cerebral hemorrhage and dystonia
C)Hypertension and renal insufficiency
D)Hypotension, dysrhythmias, and cardiac arrest -
Answer✓✓
Ans:A
Feedback:
Administration of flumazenil blocks the action of benzodiazepines. If the patient has been taking
these medications for an extended period of time, the blockage of the drug's effects could
precipitate an acute benzodiazepine withdrawal syndrome with symptoms including agitation,
confusion, and seizures. Anexate does not cause cerebral hemorrhage and dystonia,
hypertension, renal insufficiency, hypotension, dysrhythmias, and cardiac arrest.

,_____________Quiz____________?
The nurse administers promethazine (Phenergan) to the patient before sending the patient to
the preoperative holding area. What is the rationale for administration of this drug?
A)SedationB)Oral secretions C)Hypotension and bradycardia D)Confusion -
Answer✓✓
Ans:AFeedback:
Antihistamines (promethazine, diphenhydramine [Benadryl]) can be very sedating in some
people. They are used as preoperative medications and postoperatively to decrease the need
for narcotics. Promethazine is not given for hypotension, bradycardia, confusion, or oral
secretions.
_____________Quiz____________?
What reasons can the nurse give for why barbiturates are no longer considered the mainstay
for treatment of anxiety? (Select all that apply.)
A)Adverse effects are more severe.
B)There is an increased risk of physical tolerance.
C)There is an increased risk of psychological dependence.
D)The most common adverse effects are related to cardiac arrhythmias.
E)Hypersensitivity reactions can sometimes be fatal. -
Answer✓✓
Ans:A, B, C, E Feedback:
The adverse effects caused by barbiturates are more severe than those associated with other,
newer sedatives/hypnotics. For this reason, barbiturates are no longer considered the mainstay
2
,for the treatment of anxiety. In addition, the development of physical tolerance and
psychological dependence is more likely with the barbiturates than with other anxiolytics. The
most common adverse effects are related to central nervous system (CNS) depression.
Hypersensitivity reactions to barbiturates are sometimes fatal.
_____________Quiz____________?
The nurse is teaching a class for nurses working in prenatal clinics about the danger associated
with use of benzodiazepines during pregnancy and explains that what fetal anomalies result from
maternal use of benzodiazepines during the first trimester of pregnancy? (Select all that apply.)
A)Cleft lip or palate B)Inguinal hernia C)Cardiac defects D)Microencephaly E)Gastroschises -
Answer✓✓
Ans:A, B, C, D Feedback:
Benzodiazepines are contraindicated in pregnancy because a predictable syndrome of cleft lip or
palate, inguinal hernia, cardiac defects, microcephaly, or pyloric stenosis occurs when they are
taken in the first trimester. Gastroschises, when the abdominal organs are found outside the
abdominal cavity, is not associated with use of benzodiazepine use in the first trimester.
_____________Quiz____________?
The nurse is caring for a newborn who was delivered from a woman who took
benzodiazepines for anxiety during the last 2 months of her pregnancy after her husband was
killed in war. What will the nurse assess for in this newborn?
A)Newborn withdrawal syndrome B)Hepatic dysfunctionC)Failure to thriveD)Learning
deficiencies -
3
, Answer✓✓
Ans:A Feedback:
Neonatal withdrawal syndrome may result in a baby born to a mother who was taking
benzodiazepines in the final weeks of pregnancy. The neonate may be given very small doses of
benzodiazepines that are withdrawn gradually to prevent symptoms. Hepatic dysfunction in the
neonate is not associated with use of benzodiazepines. Failure to thrive and learning deficiencies
would be long-term problems and are not assessed during the neonatal period.
_____________Quiz____________?
The nurse is caring for a patient who received a new diagnosis of cancer. The patient exhibits
signs of a sympathetic stressreaction. What signs and symptoms will the nurse assess in this
patient consistent with an acute reaction to stress? (Select all that apply.)
A)Profuse sweatingB)Fast heart rateC)Rapid breathing D)HypotensionE)Inability to interact
with others -
Answer✓✓
Ans:A, B, C
Feedback:
Anxiety is often accompanied by signs and symptoms of the sympathetic stress reaction that
may include sweating, fast heart rate, rapid breathing, and elevated blood pressure. Chronically
anxious people may be afraid to
interact with other people but this is not usually seen in an acute stress reaction.
