ATI VATI Pharmacology Assessment Questions
Question 1 of 5
What makes cocaine unique among llocal anesthetics:
Correct Answer: B
Rationale: Cocaine is unique among local anesthetics because it undergoes metabolism by plasma esterases, unlike other local anesthetics which are typically metabolized by the liver. This rapid metabolism by plasma esterases contributes to its short duration of action as a local anesthetic. This property of cocaine also contributes to its potential for systemic toxicity and drug interactions, making it important to consider when using cocaine in a clinical setting.
Question 2 of 5
A patient who is taking amitriptyline (Elavil) reports constipation and dry mouth. The patient notes that these
Correct Answer: A
Rationale: The correct instruction the nurse should give the patient who is experiencing constipation and dry mouth as side effects of amitriptyline (Elavil) is to increase fluid intake. Increasing fluid intake can help alleviate these side effects. Adequate hydration can help with constipation by softening stools and making bowel movements easier, and it can also help relieve dry mouth by promoting saliva production. It is a simple and effective measure that can be taken to manage these common side effects without the need to stop the medication or switch to a different antidepressant.
Question 3 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.
Question 4 of 5
A patient complains of night blindness. The nurse correctly recommends which foods?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 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.
