Question 23 1 out of 1 points 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? Selected Answer: D. A client who has type 1 diabetes and who practices poor glycemic control Correct Answer: D. A client who has type 1 diabetes and who practices poor glycemic control 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. Question 24 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? Selected Answer: D. Restoration of normal sinus rhythm Correct Answer: D. Restoration of normal sinus rhythm 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 25 1 out of 1 points A nurse is caring for a patient who has been admitted with acute cocaine intoxication. Which of the following vital signs would the nurse expect to
find initially when assessing the patient? Selected Answer: C. BP: 170/98, P:110, R: 20 Correct Answer: C. BP: 170/98, P:110, R: 20 Response Feedback: CNS stimulants like cocaine initially increase heart rate and blood pressure. Cocaine impairs the uptake of norepinephrine and epinephrine by presynaptic nerve endings, thus activating the adrenergic systems and causing hypertension, tachycardia, and vasoconstriction.
