A nurse is preparing to administer lidocaine 50 mg IV bolus.
Available is lidocaine 200 mg/mL. How many mL should the nurse administer per dose? rounded off to the nearest hundredth

0.3 mL.

0.25 mL.

0.4 mL.

0.15 mL.

Answer and Explanation

The Correct Answer is B

Step 1: Identify the amount of lidocaine required, which is 50 mg.

Step 2: Identify the concentration of available lidocaine, which is 200 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 administer 0.25 mL of lidocaine per dose. This is the final answer and it is rounded off to the nearest hundredth as required.

Correct Answer is C

Explanation

Choice A rationale:

Material safety data sheets (MSDS) primarily contain information related to hazardous chemicals and substances used in healthcare settings. While MSDS can be valuable for safety purposes, they do not provide comprehensive information on specimen collection protocols. Therefore, MSDS is not the most appropriate source for revising the specimen collection protocol.

Choice B rationale:

Client medical records are essential for individual patient care and documentation. However, they do not contain the information needed to revise the protocol for specimen collection on the unit. Medical records are specific to individual patient histories, diagnoses, and treatments, and do not address broader unit-wide protocols.

Choice C rationale:

Facility policy and procedures are the most appropriate source for retrieving information to revise the protocol for specimen collection on the unit. These policies and procedures are specifically designed to guide healthcare providers in delivering safe and effective care within the facility. They encompass standardized protocols for various clinical procedures, including specimen collection, making them the ideal source for the nurse's research.

Choice D rationale:

Evidence-based practice (EBP) involves using the best available research evidence, clinical expertise, and patient values to guide healthcare decisions. While EBP is crucial in healthcare, it is not the primary source for revising unit-specific protocols. EBP provides a broader framework for making clinical decisions but may not cover the specific policies and procedures unique to the facility.

A. Telephone the interpreter that is designated for the facility to interpret the information. B. Call a nursing colleague who speaks the same language as the client to interpret the information. C. Ask the client's partner to interpret the information. D. Use an electronic translating service from the internet to interpret the information.
