The nurse admits a client who reports taken a proton pump inhibitor for more than a decade. What question will the nurse ask this client?

A. "The different onsets and peaks of the two types provide better overall glucose control.": Regular insulin has a rapid onset and short duration, while NPH insulin has a slower onset and longer duration. When used together, they mimic the body's natural insulin release pattern, offering both immediate and sustained glucose control throughout the day.

B. "NPH prevents regular insulin from being broken down in the body, allowing the use of a lower dose.": NPH does not alter how regular insulin is metabolized. Each insulin type acts independently, and NPH does not preserve or enhance the activity of regular insulin.

C. "The combination negates the risk of adverse effects that would likely accompany a single, larger dose.": The primary reason for using two types is to align insulin activity with the body’s varying needs. Risk reduction from side effects is not the primary purpose.

D. "NPH stimulates the pancreas to produce more insulin, while regular insulin provides your body's short-term needs.": NPH insulin is synthetic and does not stimulate pancreatic insulin production. Clients with type 1 diabetes lack insulin production altogether, so both types must be provided exogenously.

A. Allergies: Although histamine is involved in allergic reactions, H2 antagonists target histamine receptors in the stomach, not the ones responsible for allergic symptoms. H1 blockers, such as diphenhydramine or loratadine, are used to manage allergies, not H2 antagonists.

B. Gastroesophageal Reflux Disease (GERD): Histamine-2 antagonists like ranitidine and famotidine reduce gastric acid secretion by blocking H2 receptors on parietal cells. This helps relieve symptoms of GERD, such as heartburn and acid regurgitation.

C. Constipation: Constipation is unrelated to histamine activity in the gastrointestinal tract. Treatment involves stool softeners, laxatives, or dietary fiber, not acid-suppressing agents like H2 blockers.

D. Diarrhea: H2 antagonists do not reduce intestinal motility or fluid secretion and have no therapeutic role in treating diarrhea. Antidiarrheal agents like loperamide are more appropriate for managing this condition.
