ATI LPN Pharmacology Quiz Questions
Question 1 of 5
A patient who has just been prescribed an incretin enhancer, asks the nurse how it works. The nurse informs the patient that these types of medications:
Correct Answer: B
Rationale: Incretin enhancers (e.g., DPP-4 inhibitors, GLP-1 agonists) amplify incretin hormones, which stimulate insulin secretion from the pancreas in response to meals, aiding glucose control. They don’t increase insulin production, primarily reduce glucagon (a secondary effect), or decrease glucose uptake.
Question 2 of 5
The client asks the nurse which type of diabetes is caused by no insulin secretion by the pancreas. What is the best response by the nurse?
Correct Answer: D
Rationale: Type 1 diabetes is caused by autoimmune destruction of pancreatic beta cells, resulting in no insulin secretion, requiring insulin therapy. Type 2 diabetes involves insulin resistance and relative deficiency, not a complete lack of insulin. The other options misrepresent the pathophysiology of diabetes types.
Question 3 of 5
Children younger than 9 years should not be given tetracyclines because:
Correct Answer: D
Rationale: Tetracyclines deposit in developing teeth, causing permanent discoloration in children under 9. They can also affect bone growth, but tooth discoloration is the primary concern. Dehydration and photosensitivity are not age-specific tetracycline issues.
Question 4 of 5
Jennifer takes birth control pills. Recently she was diagnosed with a urinary tract infection and is taking ciprofloxacin (Cipro). To maximize the therapeutic effects of both types of drugs, what should the nurse tell Jennifer?
Correct Answer: C
Rationale: Ciprofloxacin may reduce birth control pill effectiveness, risking pregnancy. Completing the antibiotic therapy with a backup contraception method ensures infection treatment and pregnancy prevention. Changing drugs or abstaining is less practical.
Question 5 of 5
Why must the nurse instruct a patient receiving metformin (Glucophage XL) to avoid crushing or chewing the medication?
Correct Answer: D
Rationale: Glucophage XL is an extended-release formulation designed for slow metformin release. Crushing or chewing disrupts this, causing rapid drug release, which can increase side effects like hypoglycemia or GI distress, altering the intended effect.
