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.
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 D
Explanation
Choice A rationale:
There are actually five rights of delegation: right task, right circumstance, right person, right direction/communication, and right supervision/evaluation. This statement is not accurate.
Choice B rationale:
It is not the duty of the delegatee to perform a task without asking questions. Effective delegation involves clear communication, including the opportunity for the delegatee to ask questions and seek clarification as needed.
Choice C rationale:
While the nurse manager plays a role in delegation, the responsibility for delegation does not solely rest on the nurse manager. Delegation is a shared responsibility among all nurses, and the person delegating the task must ensure it is appropriate and clear.
Correct Answer is A
Explanation
Choice B rationale:
The statement "The ACA is primarily for individuals requiring tertiary care" is not accurate. The Affordable Care Act (ACA) is designed to improve access to healthcare for a broad range of individuals, not just those in need of tertiary care. It aims to make healthcare coverage more affordable and accessible for all, regardless of the level of care needed.
Choice C rationale:
The statement "Individuals must qualify to participate in ACA insurance coverage" is correct to some extent. Individuals must meet certain eligibility criteria to enroll in ACA insurance plans, such as being a U.S. citizen or lawfully present, but it does not capture the full scope of the ACA's purpose. The primary goal of the ACA is to expand access to healthcare and reduce disparities, not just limited to qualification requirements.
Choice D rationale:
The statement "Individuals with pre-existing conditions are not eligible for ACA coverage" is incorrect. One of the significant achievements of the ACA is that it prohibits insurance companies from denying coverage to individuals with pre-existing conditions. In fact, the ACA has provisions to protect individuals with pre-existing conditions and ensure their access to insurance coverage.
