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 B
Explanation
Choice A rationale:
The nurse should not inform the client of the need to pre-pay for the consent of authorization. Precertification for surgery is related to obtaining approval from the client's insurance provider and not about pre-payment.
Choice B rationale:
Contacting the client's insurance carrier to obtain authorization is the correct action to take when obtaining precertification for surgery. Many insurance companies require pre-authorization for surgical procedures to ensure coverage and to confirm that the procedure is medically necessary. This step is essential to prevent financial burdens on the client and ensure they have coverage for the surgery.
Choice C rationale:
Notifying the provider to obtain approval for the surgery is not the nurse's responsibility in the context of precertification. The primary responsibility lies with obtaining approval from the client's insurance carrier.
Choice D rationale:
Witnessing the client sign the surgical consent form is an essential step in the surgical preparation process but is not the same as obtaining precertification. Precertification involves confirming insurance coverage and approval for the surgery, which is the responsibility of the insurance carrier, not the client's consent.
