A nurse is preparing to administer lidocaine 50 mg IV bolus. Available is lidocaine 200 mg/mL. How many mL should the nurse administer (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.3"]

Calculating the Lidocaine Dose

Problem: Administer 50 mg of lidocaine IV bolus. The available concentration is 200 mg/mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (50 mg) and the concentration of the medication (200 mg/mL).

Proportion:

x mL / 50 mg = 1 mL / 200 mg

Cross-multiply:

200x = 50

Solve for x:

x = 50 / 200

x = 0.25

Answer: The nurse should administer 0.3 mL of lidocaine per dose(rounded to the nearest tenth).

Correct Answer is A

Explanation

A) Catheter dislodgment:
Hearing a gurgling sound near the catheter insertion site may indicate that the catheter is partially dislodged. This dislodgment can cause air to enter the catheter or affect the proper flow of fluids. Immediate assessment and intervention are required to address the dislodgment and prevent complications such as air embolism.

B) Catheter rupture:
A catheter rupture would typically present with signs of leakage or blood in the surrounding area, rather than a gurgling sound. While a rupture is a serious complication, it does not usually cause a gurgling noise.

C) Catheter migration:
Catheter migration occurs when the catheter moves from its original position, which could lead to issues with catheter function or placement. However, migration is less likely to cause a gurgling sound and more likely to present with changes in catheter function or resistance during infusion.

D) Catheter occlusion:
Catheter occlusion usually presents with difficulty in infusing fluids or withdrawing blood, not a gurgling sound. An occlusion is characterized by blockage or reduced flow rather than an audible gurgling.

A. Flumazenil B. Acetylcysteine C. Naloxone D. Fab antibody fragments

Correct Answer is D

Explanation

A) Flumazenil: Flumazenil is an antidote used to reverse the effects of benzodiazepines, which are central nervous system depressants. It is not effective in treating digoxin toxicity, as it does not interact with the cardiac glycoside effects of digoxin.

B) Acetylcysteine: Acetylcysteine is primarily used as an antidote for acetaminophen overdose and to help manage mucus in respiratory conditions. It has no effect on digoxin toxicity and would not be appropriate for treating this condition.

C) Naloxone: Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. Like flumazenil and acetylcysteine, naloxone is not effective in addressing digoxin toxicity and does not counteract the effects of cardiac glycosides.

D) Fab antibody fragments: Fab antibody fragments, also known as Digoxin-specific antibody fragments (Digibind or DigiFab), are the appropriate treatment for severe digoxin toxicity. These fragments bind to digoxin, neutralizing its effects and allowing the body to eliminate it safely. This is the most effective and specific treatment for life-threatening digoxin toxicity.
