Final answer:
Duramorph (morphine sulfate) should be avoided by clients with acute pancreatitis due to its potential to cause spasm of the Sphincter of Oddi. Alternative analgesics are preferable, though meperidine (Demerol) is also controversial. Pepcid (famotidine) and Zantac (ranitidine) are safe H2-receptor antagonists in this condition.
Step-by-step explanation:
The medication that should be avoided by a client with acute pancreatitis is Duramorph (morphine sulfate). Morphine can cause spasm of the Sphincter of Oddi, potentially worsening pain and exacerbating the condition in acute pancreatitis. It is generally recommended to use alternative pain management options, such as meperidine (Demerol), which is less likely to affect the sphincter. However, the use of meperidine is also controversial due to its metabolites and potential for neurotoxicity, so its use has declined in favor of other analgesics. On the other hand, Pepcid (famotidine) and Zantac (ranitidine) are H2-receptor antagonists used to reduce stomach acid production and are considered safe for use in patients with acute pancreatitis.
