## 문제

A nurse is preparing to administer medications to multiple patients during the evening shift. Which action by the nurse best demonstrates proper medication error prevention?

## 보기

1. Preparing all medications for multiple patients at once to save time and increase efficiency
2. Relying on memory to recall patient allergies and medication orders without checking the medical record.
3. Performing the "five rights" of medication administration for each patient before giving any medication **✔ 정답**
4. Administering medications based on the previous shift's verbal report without verification

**정답: 3**

## 해설

The 'five rights' are fundamental safety checks that must be performed for every medication administration to prevent errors. Other options represent unsafe practices like relying on memory or skipping verifications.

## 심화 해설

Core Nursing Explanation
**Key Concept Analysis**: This question assesses the foundational principle of safe medication administration. The core theme is identifying the single most effective action to prevent medication errors, which is a critical patient safety priority in nursing. The Five Rights of Medication Administration (Right patient, Right drug, Right dose, Right route, Right time) are a systematic, non-negotiable checklist designed to create a cognitive pause and verification process before any drug is given.

**Answer Rationale**: Key Point! Performing the "five rights" for **each patient** before **each medication** is the gold standard for error prevention. It is a proactive, structured approach that forces the nurse to verify multiple data points against the original order and patient identifiers, thereby catching potential discrepancies. This action embodies the principle of independent double-check, which is a cornerstone of safe practice.

**Distractor Analysis**:

Watch out for confusion! Option ①, preparing all medications at once, is a dangerous time-saving tactic that increases the risk of mix-ups between patients and is a direct violation of safe medication practice principles.

Option ②, relying on memory, is a high-risk behavior. Patient conditions and orders change; the medical record (MAR - Medication Administration Record) is the legal source of truth and must be checked every time.

Option ④, administering based on a verbal report without verification, is a critical error. Medication orders must be verified against the physician's written or electronic order and the current MAR. A shift report is for information, not for direct medication administration.

**Related Concepts**: Beyond the Five Rights, modern safety protocols often include additional "rights" such as the Right documentation, Right reason/indication, and Right response (evaluation). The use of barcode scanning at the bedside is a technological enhancement designed to automate and enforce the verification of the Five Rights.

Concept Summary
The Five Rights of Medication Administration are a mandatory safety procedure. Their purpose is to create a fail-safe routine to prevent errors that could cause patient harm. Adherence to this protocol is a legal and ethical nursing responsibility.

Side-by-Side Comparison!

| Safe Practice (Correct Answer) | Unsafe Practice (Distractors) |
| --- | --- |
| Performing the Five Rights systematically for each dose. | Preparing multiple patients' drugs together (increases cross-contamination risk). |
| Using the MAR (Medication Administration Record) and patient ID for verification. | Relying on memory for allergies or orders. |
| Verifying all orders against the original source. | Acting on verbal reports or assumptions without independent check. |

Anatomy, Physiology & Pharmacology Points
While this is primarily a safety procedure question, understanding pharmacokinetics (what the body does to the drug) and pharmacodynamics (what the drug does to the body) underscores why the Right dose and Right route are critical. Administering an IV push medication intended for oral use, for example, could cause immediate, severe harm due to rapid systemic absorption.

Memory Tips
Use the mnemonic **"Patients Do Drugs Round The Clock"** to remember the Five Rights: **P**atient, **D**rug, **D**ose, **R**oute, **T**ime. Think of it as your personal "pre-flight checklist" before every medication administration.

High-Frequency NCLEX Topics
Medication safety and the Five Rights are **extremely high-yield** for the NCLEX. The exam tests not only your knowledge of what the rights are, but also your ability to recognize correct and incorrect application of them in clinical scenarios. Questions often focus on the nurse's **first** or **priority** action when administering drugs.

Watch Out for Question Variations!
The NCLEX might test this concept by:
1. Presenting a scenario where a medication error **has occurred** and asking for the nurse's **priority action** (e.g., assess the patient, notify the provider).
2. Asking which action by a **nursing assistant** would require **immediate intervention** by the nurse (e.g., the assistant brings a medication to a patient).
3. Testing knowledge of **additional safety checks**, like checking patient allergies or assessing lab values (e.g., potassium level before giving digoxin).

## 임상 시나리오

Nursing Clinical Practice Guide
**Clinical Scenario**: You are on a medical-surgical floor. Your assignment includes Mr. Jones in room 204 (receiving Lasix 40 mg PO and Metoprolol 25 mg PO) and Mrs. Smith in room 206 (receiving Insulin Aspart 6 units subcutaneously before dinner). The unit is busy, and the previous nurse gives a hurried report.

**Nursing Intervention Strategy**:
1. **Assessment & Planning**: Before entering any room, review the electronic MAR for each patient. Note the drugs, doses, times, and any specific instructions (e.g., check blood glucose before insulin).
2. **Preparation**: Prepare medications for **one patient at a time**. Use the dispensing machine or medication cart. Keep each patient's medications separate.
3. **Administration & Verification**: At the bedside:
- Use two patient identifiers (e.g., name and date of birth). Key Point! Do not use room number as a sole identifier.
- Scan the patient's wristband and the medication barcode if available (this electronically verifies 4 of the 5 rights).
- Verbally state the medication, dose, and purpose to the patient when appropriate ("Mr. Jones, this is your 40 mg Lasix pill to help remove extra fluid").
- Stay with the patient until the medication is taken.
4. **Documentation & Evaluation**: Document administration immediately in the MAR. Later, evaluate for therapeutic effect and side effects (e.g., did Mr. Jones' urine output increase?).

**Patient Safety and Precautions**:
- **Contraindication Check**: Always check for known allergies (marked in the chart and often on the wristband) and relevant lab values before administration.
- **Never Interrupt**: If interrupted during medication preparation or administration, go back and restart the verification process. Do not try to "pick up where you left off."
- **High-Alert Medications**: For drugs like insulin, opioids, or anticoagulants, many facilities require an independent double-check by a second nurse before administration.

Nursing Procedure & Medication Flow
**Step-by-Step for Safe Administration**:
1. Check the original order against the MAR.
2. Perform the first check of the Five Rights when **removing** the drug from storage.
3. Perform the second check when **preparing** the drug (e.g., drawing up in a syringe).
4. Perform the third and final check at the **bedside, before giving** the drug to the patient.
5. Administer the drug via the correct route (know the landmarks for IM injections, angle for subQ, etc.).
6. Dispose of supplies safely (e.g., in a sharps container).
7. Document promptly and accurately.

A Word from Your Senior Nurse
"Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In clinical practice, the simple act of consistently performing the Five Rights is your most powerful shield against harm. I've seen near-misses caught because a nurse took that extra three seconds to verify the dose. When studying for your boards, don't just memorize the list — internalize it as a non-negotiable ritual. That mindset will not only earn you a great score on the NCLEX but will make you a truly confident, professional nurse who patients can trust with their lives."

## 핵심 개념

- **Five Rights of Medication Administration** — The fundamental safety checks: Right Patient, Right Drug, Right Dose, Right Route, Right Time. It is the cornerstone of safe medication practice.
- **Medication Administration Record** — The legal document that details a patient's medication orders, schedules, and administration history. It is the primary reference for nurses during medication passes.
- **High-Alert Medications** — Drugs that bear a heightened risk of causing significant patient harm when used in error (e.g., insulin, opioids, anticoagulants). Often require special safeguards like independent double-checks.
- **Independent Double-Check** — A safety procedure where two qualified healthcare professionals separately verify critical components of a medication order and product before administration.
- **Patient Identification** — The process of using at least two patient-specific identifiers (e.g., name, date of birth, medical record number) to verify identity before providing care, treatment, or services. Room number is not an acceptable identifier.
