ATI VATI Pharmacology Assessment Questions
Question 1 of 5
The most productive way of managing stress would be to
Correct Answer: A
Rationale: Combining drugs (e.g., benzos) with nonpharmacological methods (e.g., meditation) balances quick relief and long-term coping, per stress management best practices. Anxiolytics alone risk dependence. Meditation helps but may not suffice. Addressing the cause is ideal but often slow-combined approach leverages both, enhancing outcomes.
Question 2 of 5
What route can ondansetron be given? (select all that apply)
Correct Answer: A
Rationale: Ondansetron, which is commonly used to prevent nausea and vomiting, can be administered via three routes: Orally (PO), Intravenously (IV), and Rectally (Rectal). These routes allow for flexible administration based on the patient's condition and needs. Intramuscular (IM) administration is not a recognized route for ondansetron administration.
Question 3 of 5
Chemotherapy induces vomiting by:
Correct Answer: A
Rationale: Chemotherapy-induced vomiting is primarily caused by the stimulation of neuroreceptors in the medulla oblongata, particularly the chemoreceptor trigger zone (CTZ). The CTZ is sensitive to chemical stimuli and responds to the presence of chemotherapy drugs by triggering the vomiting reflex. While irritation of the gastric mucosa can contribute to nausea, it is not the primary mechanism. Autonomic instability and inhibition of catecholamines are not directly related to chemotherapy-induced vomiting. Anti-emetic medications often target these neuroreceptors to prevent or reduce vomiting.
Question 4 of 5
A 27-year-old man with recurrent asthma attacks is being considered for preventative therapy with cromolyn sodium. This agent is not effective as an acute treatment of an asthma attack because of the lack of which of the following properties?
Correct Answer: B
Rationale: Cromolyn sodium prevents asthma by stabilizing mast cells, but lacks bronchodilator action. It has anti-inflammatory and mast cell stabilizer properties, and some immune modulation , but doesn't relieve acute bronchospasm, limiting it to prophylaxis.
Question 5 of 5
The nurse provides patient teaching for a patient who has a new order for nadolol (Corgard) to treat hypertension. What statement by the patient concerning nadolol (Corgard) would indicate that the teaching has been effective?
Correct Answer: C
Rationale: A patient receiving an adrenergic blocker must be aware that abruptly stopping the medication may result in a serious reaction. When changing medications or discontinuing their use, these drugs need to be tapered off gradually. This drug is not associated with photophobia or the anticholinergic effect of dry mouth. If the teaching were effective, the patient would be aware that he would need to continue lifestyle modifications, including diet and exercise.
