A client is to receive a medication at 9:00 A.M. To prevent a medication error by administering at the incorrect time, the nurse can administer the medication anytime between:
8:00 and 10:00 A.M.
8:30 and 9:30 A.M.
8:30 and 9:00 A.M.
8:45 and 9:15 A.M.
The Correct Answer is D
Choice A reason: Two-hour window (8:00-10:00) is too broad; most protocols allow 30 minutes before/after, as wider ranges risk altering drug pharmacokinetics significantly.
Choice B reason: One-hour window (8:30-9:30) is common but exceeds some strict policies; it’s less precise, potentially affecting drugs with tight timing needs.
Choice C reason: 8:30-9:00 is only before; it excludes post-9:00 flexibility, limiting administration to early dosing, which may not align with full protocol windows.
Choice D reason: 8:45-9:15 (30 minutes either side) fits standard policy; it ensures therapeutic levels for most drugs, balancing efficacy with practical scheduling.

Correct Answer is A
Explanation
Choice A reason: Right patient ensures identity verification; errors here cause harm via misadministration, as drugs affect individuals differently based on physiology and condition.
Choice B reason: Right drug prevents wrong medication errors; each drug’s pharmacokinetics targets specific issues, and mistakes disrupt therapy or cause adverse reactions.
Choice C reason: Color isn’t a standard right; it’s not a reliable identifier, as formulations vary, and clinical safety relies on name, dose, and route, not appearance.
Choice D reason: Right route ensures correct delivery (e.g., IV vs. oral); wrong routes alter bioavailability and onset, risking toxicity or inefficacy per drug design.
Choice E reason: Right time optimizes efficacy; timing aligns with drug half-life and patient needs, preventing under- or overdosing from improper administration schedules.
Correct Answer is B
Explanation
Choice A reason: Checking with another nurse may occur, but it’s not mandatory for all schedule II drugs; documentation is the primary legal responsibility to track controlled substances accurately.
Choice B reason: Signing out on a narcotic sheet is required; schedule II drugs like opioids need strict tracking to prevent diversion, ensuring accountability per federal and hospital regulations.
Choice C reason: Leaving medication at the bedside violates security; schedule II drugs must remain controlled, as unattended narcotics risk theft or misuse, breaching safety protocols entirely.
Choice D reason: Extra water is irrelevant to responsibility; it’s a hydration tip, not a legal or safety duty tied to administering highly regulated schedule II controlled substances.
