A nurse is preparing to provide an in-service to the community about misoprostol (Cytotec). Which of the following statements should the nurse include in her teaching to the community?
"An indication for this medication is used in clients taking short-term NSAIDs to prevent duodenal ulcers."
"This medication is indicated for female clients expecting a child or are currently pregnant."
"This medication is contraindicated for female clients expecting a child or are currently pregnant."
"An indication for this medication is used in clients to prevent stress-induced ulcers."
The Correct Answer is C
A. 4 teaspoons – This is incorrect because 4 teaspoons would provide 400 mg (100 mg x 4 = 400 mg), but the correct dose per administration is 400 mg. However, this is not the correct calculation, as only 2 teaspoons are needed.
B. 2 teaspoons – This is correct. The prescribed dose is 400 mg, and since the medication concentration is 100 mg per teaspoon, 2 teaspoons (100 mg x 2 = 200 mg) is the correct dose for each administration.
C. 1 teaspoon – This is incorrect because 1 teaspoon would only provide 100 mg, and the prescribed dose is 400 mg. This is not enough to meet the prescribed dose.
D. 3 teaspoons – This is incorrect because 3 teaspoons would provide 300 mg (100 mg x 3 = 300 mg), which is not enough to meet the prescribed 400 mg dose.

Correct Answer is D
Explanation
A. Ondansetron agonizes serotonin receptors on afferent vagal neurons. – This is incorrect. Ondansetron works by blocking, not activating, serotonin (5-HT3) receptors in areas involved in nausea and vomiting.
B. Ondansetron agonizes serotonin receptors in the medulla oblongata. – This is incorrect. Ondansetron does not act as an agonist at serotonin receptors in the medulla oblongata; instead, it antagonizes receptors to reduce nausea.
C. Ondansetron agonizes dopaminergic receptors in the vestibular apparatus. – This is incorrect. Ondansetron does not affect dopaminergic receptors or the vestibular apparatus. Medications like promethazine address dopaminergic pathways.
D. Ondansetron blocks serotonin receptors in the chemoreceptor trigger zone. – This is correct. Ondansetron acts as a 5-HT3 receptor antagonist, blocking serotonin receptors in the chemoreceptor trigger zone and vagal nerve terminals, effectively preventing nausea and vomiting.
