ATI LPN Pharmacology Quiz Questions
Extract:
Question 1 of 5
The nurse is admitting a client to the acute care floor with methicillin-resistant S. aureus. The nurse would expect the physician to order which of the following medications for the client?
Correct Answer: B
Rationale: Vancomycin is a standard treatment for MRSA, which is resistant to penicillin. Streptomycin and kanamycin are not typically first-line for MRSA infections.
Question 2 of 5
Which of the following common habit of patients may cause microbes to repopulate and re-establish an infection?
Correct Answer: B
Rationale: Stopping antibiotics prematurely allows surviving microbes to multiply, leading to infection recurrence or resistance. Prophylactic OTC use, switching therapies, or increasing doses are less likely to directly cause repopulation if managed appropriately.
Question 3 of 5
Which of the following orders would the LPN question in a patient with Type I diabetes?
Correct Answer: B
Rationale: Acarbose is an alpha-glucosidase inhibitor used for Type 2 diabetes to slow carbohydrate absorption, not typically for Type 1 diabetes where insulin is the primary treatment due to the absence of insulin production. Insulin glargine, lispro, and regular are all appropriate for Type 1 diabetes management, providing basal or bolus insulin coverage.
Question 4 of 5
Mr. Carter has been recently started on an antibiotic, and has developed a rash and pruritis. You suspect an allergic reaction and immediately assess him for other more serious symptoms. What question would be most important to ask Mr. Carter?
Correct Answer: D
Rationale: Difficulty breathing indicates potential anaphylaxis, a life-threatening allergic reaction requiring immediate intervention. Blood in stool, hearing issues, or headaches are less urgent and not specific to severe allergic responses.
Question 5 of 5
Which of the following stimulates the pancreas to secrete insulin?
Correct Answer: B
Rationale: Hyperglycemia (elevated blood glucose) triggers pancreatic beta cells to secrete insulin to lower glucose levels. Ketoacids result from low insulin, hypoglycemia reduces insulin secretion, and glucagon raises glucose, not directly stimulating insulin.
