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 A

Explanation

Choice A reason: Alcohol and hepatitis C impair liver function; acetaminophen’s metabolite NAPQI accumulates, causing hepatotoxicity in an already compromised organ.

Choice B reason: COPD and smoking affect lungs, not liver; acetaminophen metabolism is minimally impacted, posing lower hepatic risk compared to liver disease states.

Choice C reason: Renal disease affects drug excretion, not liver metabolism; acetaminophen’s hepatic load is unchanged, making liver damage less likely here.

Choice D reason: Prostate issues involve urinary tract; liver metabolism of acetaminophen remains intact, with no heightened risk of hepatotoxicity from this condition.

A. Used by retailers to sell the drug. B. Recognized as its chemical makeup. C. Used in an order. D. Trademarked.

Correct Answer is D

Explanation

Choice A reason: Retailers use trade or generic names; trade isn’t exclusive here, as generics are sold too, making this a shared rather than unique trait.

Choice B reason: Chemical names define molecular structure (e.g., acetaminophen); trade names (e.g., Tylenol) are brand-specific, not tied to chemistry recognition.

Choice C reason: Orders use trade or generic names (e.g., Zestril or lisinopril); trade isn’t the only option, as generics are equally valid in prescriptions.

Choice D reason: Trade names are trademarked (e.g., Viagra); this legal protection distinguishes them from generic or chemical names, ensuring brand exclusivity.
