Which medication would you question if ordered by the provider to treat a person that is complaining of nausea and vomiting?

Famotidine (Pepcid) is a medication that acts as an H2 receptor antagonist, primarily used to reduce stomach acid production. While it is effective for conditions like gastroesophageal reflux disease (GERD) and peptic ulcers, it does not directly address symptoms of nausea and vomiting.

In the context of treating nausea and vomiting, other options like promethazine, metoclopramide, and ondansetron are more appropriate as they have specific actions to alleviate these symptoms. Promethazine and metoclopramide are both antiemetics, with metoclopramide also enhancing gastric motility, which can be beneficial in certain cases of nausea. Ondansetron, a serotonin antagonist, is particularly effective for preventing nausea associated with chemotherapy and surgery.

Thus, questioning the order of famotidine for a patient experiencing nausea and vomiting makes sense, as this medication does not effectively treat the underlying symptoms, unlike the other options listed.
