A nurse is preparing to reconstitute a vial of powdered medication for a pediatric patient. Which assessment should the nurse perform FIRST before beginning the reconstitution process?

## 보기

1. Check the patient's allergy history and current vital signs
2. Verify the correct needle size for intramuscular injection
3. Examine the vial for cracks, expiration date, and label accuracy **✔ 정답**
4. Calculate the correct dosage based on the patient's weight

**정답: 3**

## 해설

Before reconstituting any medication, the nurse must first assess the vial for cracks, expiration date, and label accuracy to ensure physical integrity and safety. Other assessments are important but should follow this initial check.

Understanding the Priority Assessment Before Reconstitution

Before you even open the packaging, your first action must be a physical and visual inspection of the medication vial itself. This aligns directly with the fundamental Rights of Medication Administration, specifically the "right drug" and the "right time" (checking expiration). The framework described in the literature emphasizes that medication errors are preventable events that require systematic safety checks at every step, starting with the integrity of the product .

When you examine the vial, you are performing a critical safety barrier. Checking for cracks is non-negotiable because a breach in the container compromises sterility; reconstituting a drug in a cracked vial introduces a direct risk of bacterial contamination and local sterile abscess formation, a complication highlighted in pediatric injection safety research [3]. Verifying the expiration date ensures the chemical stability and potency of the powder, which is a cornerstone of pharmaceutical product care and safe compounding practices . Confirming label accuracy against the medication administration record (MAR) closes the loop on the "right drug" and "right patient" before you invest time in preparation.

The other options represent steps that are clinically important but occur at different points in the workflow. Calculating the dosage based on weight is a cognitive step that should happen when the order is received and verified, but if the vial is expired or damaged, that calculation is moot. Checking allergy history and vital signs is a pre-administration assessment, not a pre-reconstitution step. Selecting the needle size is a consideration for the administration route, which comes after the drug is correctly prepared. By prioritizing the physical inspection of the vial, you prevent the waste of resources and, more importantly, avoid the risk of inadvertently administering a contaminated or incorrect product to a pediatric patient .References (research sources)

Clinical Practice Guide: Reconstituting Medication for a Pediatric Patient

Priority Assessment Sequence

The first physical action before reconstitution is a visual inspection of the vial. Examine the glass or plastic for cracks, chips, or breaches that compromise sterility. Verify the medication label against the Medication Administration Record (MAR) for the correct drug, strength, and patient. Check the expiration date to ensure potency and chemical stability. This aligns with the "right drug" and "right time" principles and prevents contamination risks such as sterile abscess formation.

Workflow Integration

Dosage calculation based on weight is a cognitive verification step completed when the order is received. Patient allergy history and vital signs are assessed at the bedside prior to administration. Needle size selection occurs after the medication is prepared. Integrating these steps in the correct sequence—inspect, calculate, prepare, assess, administer—establishes multiple safety barriers against medication errors.

Pediatric Considerations

Pediatric patients are at increased risk for dosing errors and injection site complications. Strict aseptic technique during reconstitution is critical due to immature immune responses. Always use the exact diluent type and volume specified by the manufacturer to achieve the correct concentration for weight-based dosing.

## 핵심 개념

- **Rights of Medication Administration** — A systematic checklist including right patient, right drug, right dose, right route, right time, and right documentation to prevent errors.
- **Reconstitution** — The process of adding a diluent to a powdered medication to create a liquid solution or suspension for administration.
- **Sterile Abscess** — A localized collection of pus that forms at an injection site due to contamination, often from non-sterile equipment or medication.
