A nurse in an emergency department is performing triage on a group of clients.
Which of the following clients should the nurse see first?

Step 1: Identify the amount of lidocaine required, which is50 mg.

Step 2: Identify the concentration of available lidocaine, which is200 mg/mL.

Step 3: Calculate the volume of lidocaine to be administered using the formula:

Volume (mL) = Amount (mg) ÷ Concentration (mg/mL)

So, the calculation is:

Volume (mL) = 50 mg ÷ 200 mg/mL = 0.25 mL

Therefore, the nurse should administer0.25 mLof lidocaine per dose. This is the final answer and it is rounded off to the nearest hundredth as required.

Choice A rationale:

Charting by exception (CBE) is a documentation method in which the nurse documents only unexpected findings or significant deviations from the client's normal condition. It is based on the assumption that the client's baseline status remains within the expected range, and deviations from this norm are documented. CBE is efficient and allows nurses to focus on relevant and critical information, reducing unnecessary documentation. It is particularly useful in clinical settings where frequent assessments are needed.

Choice B rationale:

Focus charting (DAR) is another method of documenting client care that emphasizes a structured approach to documentation, with a focus on data, action, and response (DAR). While it provides a systematic way to document care, it does not necessarily limit documentation to only unexpected findings. Focus charting encourages documentation of care in a problem-oriented manner, which may include expected or routine assessments.

Choice C rationale:

Problem-oriented medical record (POMR) is a documentation system that focuses on organizing client information around specific healthcare problems or diagnoses. It encourages a problem-solving approach to care and promotes the inclusion of a comprehensive client history and care plan. POMR documentation may involve both expected and unexpected findings, so it does not limit documentation to only unexpected findings.

Choice D rationale:

SOAP documentation stands for Subjective, Objective, Assessment, and Plan. It is a structured method of documenting healthcare encounters. SOAP notes include a wide range of information, including both subjective (patient's description of symptoms) and objective (clinician's observations) data. While SOAP notes are organized, they do not specifically limit documentation to only unexpected findings.
