ATI VATI Pharmacology Assessment Questions
Question 1 of 5
Prescribed if a patient is allergic with Penicillin:
Correct Answer: B
Rationale: Erythromycin is a suitable alternative for patients allergic to penicillin. Erythromycin belongs to the macrolide class of antibiotics and is effective against a wide range of bacterial infections. It is generally well-tolerated and can be used as an alternative in cases of penicillin allergy.cephalosporins, tetracyclines, sulfonamides, and aminoglycosides like gentamicin should not be prescribed to a patient with a known penicillin allergy as they can potentially cross-react and cause allergic reactions.
Question 2 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 3 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 4 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 5 of 5
Which of the following contributes most to the debilitation of an individual during a course of chemotherapy?
Correct Answer: A
Rationale: Diarrhea is one of the most debilitating side effects of chemotherapy because it can lead to severe dehydration, electrolyte imbalances, and malnutrition. Persistent diarrhea can significantly impact the patient's quality of life, causing fatigue, weakness, and discomfort. While alopecia, constipation, and pain are also common side effects, diarrhea poses a greater immediate risk to the patient's physical health and ability to continue treatment. Managing diarrhea is therefore a priority in chemotherapy care.
