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

A.

0.3 mL.

B.

0.25 mL.

C.

0.4 mL.

D.

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 B

Explanation

Choice A rationale:

"The use of social media is not included in the COE.”. This statement is not accurate. The use of social media is addressed in the Code of Ethics (COE) for nurses. The COE provides guidance on how nurses should maintain professional boundaries and ethical behavior in the digital age, which includes considerations for social media use.

Choice B rationale:

"Professional expectations are included in the COE.”. This statement is correct. The Code of Ethics (COE) for nurses outlines the professional expectations and standards that nurses are expected to adhere to. It provides guidance on ethical conduct, accountability, and the responsibilities of nurses in their practice.

Choice C rationale:

"Student nurses are not held accountable to COE.”. This statement is not accurate. Student nurses are expected to adhere to the same ethical standards outlined in the Code of Ethics (COE) as registered nurses. While there may be some variations in practice expectations based on the level of training, ethical principles apply to all nurses, including student nurses.

Choice D rationale:

"Criteria for obtaining licensure is included in the COE.”. This statement is not accurate. The Code of Ethics (COE) primarily focuses on ethical principles, professional behavior, and the responsibilities of nurses in their practice. It does not typically include criteria for obtaining licensure, as licensure requirements are determined by licensing boards and regulatory bodies.

Correct Answer is ["4"]

Explanation

To calculate the correct dose in milliliters (mL), you can use the formula: Desired Dose (in mg) = Available Dose (in mg/mL) * Volume (in mL)

Desired Dose (in mg) = 40 mg Available Dose (in mg/mL) = 10 mg/1 mL Now, plug these values into the formula: Volume (in mL) = 40 mg / 10 mg/1 mL Volume (in mL) = 4 mL.

The nurse should administer 4 mL of furosemide per dose.
