A client is prescribed cimetidine 400 mg PO twice daily. It is available as an oral liquid of 100 mg per teaspoon. How many teaspoons should the client take per dose?
4 teaspoons
2 teaspoons
1 teaspoon
3 teaspoons
The Correct Answer is B
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. Sucralfate does not neutralize gastric acid; antacids are responsible for neutralization.
B. Sucralfate does not mimic endogenous prostaglandins. Medications like misoprostol act as prostaglandins to protect the stomach lining.
C. Sucralfate does not block H2 receptors. Medications like cimetidine or ranitidine work through this mechanism to reduce acid production.
D. Sucralfate creates a viscous, protective barrier that adheres to the ulcer site, shielding it from further damage by gastric acid, bile, and pepsin for up to 6 hours, thereby promoting healing.
Correct Answer is A
Explanation
A. Prolonged QT interval – This is correct. Ondansetron can cause prolongation of the QT interval, increasing the risk of arrhythmias, including torsades de pointes. This is a serious complication that requires monitoring, particularly in clients with cardiac risks.
B. Extrapyramidal symptoms – This is incorrect. Ondansetron does not typically cause extrapyramidal symptoms, which are more associated with dopamine antagonists like metoclopramide or prochlorperazine.
C. Nausea – This is incorrect. Ondansetron is specifically used to treat nausea and vomiting, not to cause them. If nausea persists, it may indicate treatment failure or another underlying issue.
D. Vomiting – This is incorrect. Ondansetron is an antiemetic and works to prevent vomiting. Vomiting would not be a complication of this medication under proper use.
