When preparing medications for delivery to an assigned patient, the nurse should check each medication for accuracy of drug and dose:

One time.

Two times.

Three times.

Five times.

Answer and Explanation

The Correct Answer is C

Choice A reason: Checking medications only once increases the likelihood of errors. Safe practice requires multiple verification steps.

Choice B reason: While better than a single check, verifying only twice may still miss potential discrepancies in drug or dosage accuracy.

Choice C reason: The three-check system (when retrieving, preparing, and administering medication) minimizes errors, ensuring patient safety through consistent validation at each step.

Choice D reason: Excessive verification may delay administration, reducing practicality without significantly improving safety beyond three checks.

Correct Answer is B

Explanation

Choice A reason: A 12-degree angle is too shallow, increasing the risk of incorrect placement and ineffective administration of the intradermal injection.

Choice B reason: The 15-degree angle ensures precise intradermal placement, forming a wheal that indicates proper administration into the dermis for optimal absorption.

Choice C reason: A 30-degree angle places the medication too deep into subcutaneous tissue, compromising intended drug absorption.

Choice D reason: A 45-degree angle results in subcutaneous rather than intradermal injection, altering the drug’s effectiveness and purpose.

A. Lungs B. Liver C. Kidney D. Colon

Correct Answer is B

Explanation

Choice A reason: Lungs excrete volatile drugs like anesthetics; most medications aren’t metabolized here, as they lack the cytochrome enzymes needed for broad drug breakdown.

Choice B reason: The liver is the primary site; cytochrome P450 enzymes metabolize most drugs, converting them into active or excretable forms, critical for pharmacokinetics.

Choice C reason: Kidneys excrete metabolites; they filter, not metabolize, most drugs, relying on prior liver processing, making them secondary in the metabolic pathway.

Choice D reason: The colon absorbs some drugs but doesn’t metabolize most; its role is minimal compared to the liver’s extensive enzymatic drug transformation capacity.
