Question 1 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.
Question 2 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 3 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 4 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.
Question 5 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.
