Loperamide (mad um)
Cimet dine Tagamer HB)
Docusate sad bin (Colace)
Sucralfate (Carafate)
The Correct Answer is D
A. Loperamide (Imodium): This is an anti-diarrheal medication and does not protect mucosal ulcers.
B. Cimetidine (Tagamet HB): Cimetidine is an H2 blocker used to reduce stomach acid, but it does not form a protective barrier like sucralfate.
C. Docusate sodium (Colace): This is a stool softener and is not used for protecting gastric ulcers.
D. Sucralfate (Carafate): Sucralfate is a mucosal protectant that binds to the ulcer and creates a protective barrier, preventing further injury from stomach acid and pepsin.

Correct Answer is B
Explanation
A. This is not the correct action because the issue with misoprostol in pregnancy is not related to the route of administration, but rather its potential to cause uterine contractions and harm to the pregnancy. The nurse should not administer the medication at all, regardless of the route, and should notify the physician for further clarification.
B. Misoprostol is contraindicated in pregnancy because it can cause uterine contractions, which may result in a miscarriage or preterm labor. The nurse should not administer this medication and must inform the healthcare provider to reconsider the prescription or explore alternative options to prevent stomach ulcers in pregnant clients.
C. Administering misoprostol to a pregnant client is dangerous, as it can stimulate uterine contractions and threaten the pregnancy. Monitoring for adverse reactions would not be an appropriate course of action, as the medication should not be given to begin with.
D. Even though verifying the patient's identity is always an important step, the main concern here is that misoprostol is contraindicated during pregnancy. The nurse should not administer this medication and must first clarify with the healthcare provider if it is suitable for the pregnant patient.
