The nurse is screening a group of clients. Which client has the greatest risk for developing type 2 diabetes?

A. Erythromycin (E-mycin): Erythromycin is a macrolide antibiotic, which has a different chemical structure from penicillins, making it safe for patients with penicillin allergies.
B. Piperacillin-tazobactam (Zosyn): Piperacillin-tazobactam is a penicillin derivative and should be avoided in patients with penicillin allergies due to the risk of cross-reactivity.
C. Ampicillin sulbactam (Unasyn): Ampicillin is a penicillin antibiotic, and therefore, should not be used in patients with penicillin allergies.
D. Cefazolin (Kefzol): Cefazolin is a cephalosporin antibiotic. There is a potential for cross-reactivity in patients with penicillin allergies, especially if the allergy is severe. It may be used with caution or avoided depending on the patient's allergy history.

A. Increase insulin production by the pancreas: This is incorrect because incretin enhancers don't increase the production of insulin itself but rather enhance the secretion of insulin in response to meals.
B. Increase insulin secretion from the pancreas: This is correct. Incretin enhancers (e.g., DPP-4 inhibitors or GLP-1 receptor agonists) work by amplifying the effect of incretins, which are hormones that increase insulin secretion in response to meals.
C. Decrease the amount of glucagon produced by the pancreas: This is partly true but not the primary mechanism. Incretins do reduce glucagon release, which helps lower blood glucose, but the main action is to increase insulin secretion.
D. Decrease the uptake of glucose by the body's cells: This is incorrect. Incretin enhancers do not work by decreasing glucose uptake by cells; rather, they enhance insulin secretion which in turn helps cells to uptake glucose.
