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 B
Explanation
Choice A rationale:
Assessment Assessment is the first step of the nursing process, where the nurse collects data about the patient's condition. While this step is crucial for understanding the patient's needs, it does not involve formulating goals for a positive outcome. Therefore, it is not the correct choice in this context.
Choice B rationale:
Planning Planning is the step of the nursing process where the nurse formulates goals and develops a care plan to achieve those goals. This includes setting objectives for the patient's care and determining the best course of action. In this case, the nurse is formulating goals for a positive outcome, making choice B the correct answer.
Choice C rationale:
Evaluation Evaluation is the step where the nurse assesses the patient's response to the care provided and determines whether the goals have been met. While important, it does not involve the initial formulation of goals, so it is not the correct choice for this question.
Choice D rationale:
Implementation Implementation involves carrying out the plan of care, putting the planned interventions into action. It doesn't focus on goal formulation, so it is not the correct answer in this context.
