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 1 out of 1 points 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.
Question 8 1 out of 1 points 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 1 out of 1 points 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.

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.
