Epinephrine is contraindicated because of possible

oxygen therapy. Epinephrine is contraindicated because of possible cardiac
stimulation. Arrhythmias may occur. Monitoring blood pressure and pulse is
important; however, the patient could be short of breath due to the hypoxia.
Therefore, monitoring respirations would be the priority. Nausea and vomiting
could be present, and the nurse would need to provide the patient with an
emesis basin, but it would not be the most important nursing intervention.
 Question 7

Which of the following would be an expected outcome in a patient who has been given
atropine during a medical emergency?
Response
Feedback:
Atropine is used to help restore normal sinus rhythm in emergency situations,
such as symptomatic bradycardia, pulseless electrical activity, ventricular
asystole, or cardiopulmonary resuscitation. It does not resolve acid-based
imbalances or decreased level of consciousness and atropine increases, rather
than decreases, blood pressure.

A nurse is talking to an 18-year-old patient who has had a seizure disorder since she was 10
years old and is taking phenytoin (Dilantin). The nurse should suggest that she take which of
the following?
Response
Feedback:
Long-term phenytoin therapy is associated with folate deficiency. Folic acid
and phenytoin are structurally similar and thought to compete with each other
for the same receptors. A deficiency in folic acid in a pregnant woman can
cause birth defects. Potassium, iron, and vitamin C do not compete with
phenytoin nor are they directly affected by phenytoin.
 Question 9

Which of the following drugs used to treat anxiety would be appropriate for a patient who is a
school teacher and is concerned about feeling sedated at work?
Response
Feedback:
Buspirone does not cause as much sedation and functional impairment as
lorazepam, alprazolam, and diazepam. However, it can cause dizziness,
nausea, headache, nervousness, lightheadedness, or excitement.
 Question 10

A nurse who works at an outpatient mental health clinic follows numerous clients who have
schizophrenia, many of whom are being treated with olanzapine (Zyprexa). Which of the
following clients likely has the highest susceptibility to the adverse effects of olanzapine?
Response
Feedback:
The use of olanzapine creates a significant risk of hyperglycemia. This is of
particular concern in patients and clients who have diabetes mellitus. Smoking
affects the pharmacodynamics of olanzapine, but this is less likely to result in
serious adverse effects. Obesity, low BMI, and recent antibiotic use are not
associated with a significantly increased risk of adverse effects.
