Final answer:
An effective client statement would demonstrate understanding that antacids provide temporary relief from heartburn, whereas famotidine reduces stomach acid production over a longer duration, and that these medications should be taken at different times to avoid interference.
Step-by-step explanation:
The client statement that indicates to the practical nurse (PN) that teaching was effective regarding the concurrent use of the H2 receptor blocker famotidine (Pepcid) and antacids would likely be an acknowledgment that antacids neutralize stomach acid temporarily, providing quick relief from heartburn and indigestion, while famotidine works over a longer period to reduce the production of stomach acid.
Antacids should generally be taken as needed for symptoms, but not at the same time as famotidine, as they can interfere with the absorption of the H2 blocker. The client should understand that while antacids provide symptomatic relief, they do not treat the underlying cause of chronic gastritis or GERD, for which famotidine is prescribed. If the client understands that taking famotidine regularly at prescribed intervals, and using antacids separately when needed, they are demonstrating effective understanding of their medication regimen.
