Which type of tablet is specifically designed to bypass dissolution in the stomach to protect the gastric lining?
Suspension
Capsule
Powder
Enteric coated
The Correct Answer is D
A. Suspension: A suspension is a liquid preparation in which solid drug particles are dispersed in a liquid. It does not provide protection from gastric acid or prevent irritation of the stomach lining.
B. Capsule: Capsules enclose medication in a gelatin shell, which dissolves in the stomach or intestine. Standard capsules do not prevent gastric irritation unless they are specifically formulated with protective coatings.
C. Powder: Powders are solid medications that are usually mixed with liquid before administration. They dissolve quickly and do not protect the gastric mucosa from irritation.
D. Enteric coated: Enteric-coated tablets are designed with a special coating that resists dissolution in the acidic environment of the stomach. They remain intact until reaching the more neutral pH of the small intestine, protecting the gastric lining and preventing acid-mediated drug degradation.

Correct Answer is D
Explanation
Calculation:
- Identify the total volume and infusion rate
Total Volume: 720 mL
Infusion Rate: 60 mL/hr
- Calculate the time the bag will last
Time (hours) = Total Volume ÷ Infusion Rate
Time = 720 ÷ 60
= 12 hours
Correct Answer is D
Explanation
A. Skip manual checks since barcoding ensures accuracy: Barcoding significantly reduces errors but is not infallible. System errors, mislabeling, or scanning failures can occur, so skipping verification can compromise patient safety.
B. Use the barcoding system only for high-risk medications: Barcoding should be applied to all medications to ensure consistency and safety, not limited to high-risk drugs. Limiting its use increases the potential for errors with routine medications.
C. Rely solely on the barcoding system for verification: While barcoding aids in verification, nurses must also apply clinical judgment and confirm correct patient, medication, dose, route, and timing. Sole reliance on technology can miss errors the system does not detect.
D. Conduct a manual check of the medication with the MAR before administration to ensure the medications match: Performing a manual comparison between the medication and the MAR provides an additional safety layer. This step verifies that the correct drug, dose, and route are administered to the right patient, complementing the barcoding system.
