The term used to describe the space outside the cell that includes interstitial and intravascular areas is:

A. Check the medication's expiration date after administration: Verifying expiration after giving a medication does not prevent the administration of an ineffective or potentially harmful drug. Safety requires checking the expiration before administration.

B. Ask the client if they have any questions about the medication after administration: While educating the client is important, this should occur before the medication is given to ensure understanding, consent, and safe use. Post-administration questions cannot prevent errors.

C. Confirm the medication with the client's family: Family input may be helpful, but the primary responsibility for verifying the correct medication lies with the nurse and the prescribed orders. Family confirmation cannot replace independent verification.

D. Review the medication label against the MAR at the client's bedside: Comparing the medication label with the MAR at the bedside ensures the right client, drug, dose, route, and time, adhering to the “five rights” of medication administration. This verification is the most important step to prevent medication errors.

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.
