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 ["C","D","E"]
Explanation
The correct answer is to select the following three findings that require immediate follow-up:C. Urticaria,D. Blood pressure at 1630, andE. Report of dysphagia.
Choice A rationale:
“Breath sounds at 1600.” The breath sounds at 1600 were clear and present throughout, which is a normal finding and does not require immediate follow-up.
Choice B rationale:
“Temperature.” The temperature readings at both 1600 and 1630 are slightly elevated but not critically high. This does not require immediate follow-up compared to the other findings.
Choice C rationale:
“Urticaria.” The presence of urticaria (hives) indicates an allergic reaction, which can potentially escalate to a more severe reaction such as anaphylaxis.Immediate follow-up is necessary to prevent further complications.
Choice D rationale:
“Blood pressure at 1630.” The blood pressure at 1630 is significantly lower (78/52 mm Hg) compared to the earlier reading (110/58 mm Hg).This hypotension could indicate a serious reaction to the medication or another underlying issue that requires prompt attention.
Choice E rationale:
“Report of dysphagia.” The client’s report of difficulty swallowing and feeling a lump in their throat is concerning for a potential airway obstruction or severe allergic reaction, such as anaphylaxis.This symptom requires immediate follow-up to ensure the client’s airway remains open and to provide necessary interventions.
