A nurse is caring for a client who is taking digoxin for heart failure and develops indications of severe digoxin toxicity. Which of the following medications should the nurse prepare to administer?

Flumazenil

Acetylcysteine

Naloxone

Fab antibody fragments

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is C

Explanation

A) Wear sterile gloves and break off the neck of the glass ampule with a single snap to the right side:
While wearing gloves can be part of the technique, breaking the ampule to the right side is not standard practice. It is more important to use a sterile gauze pad and break the ampule carefully to avoid glass shards falling into the medication.

B) Tap the bottom of the ampule, place a gauze pad around the ampule neck, and break off the bottom with a forward motion away from the body:
Tapping the bottom of the ampule is not the recommended practice; the top of the ampule should be tapped instead. Additionally, breaking the ampule away from the body is good practice, but it’s crucial to break the top of the ampule, not the bottom.

C) Tap the top of the ampule, place a sterile gauze pad around the ampule neck, and break off the top by bending it toward the body:
This is the correct technique. Tapping the top of the ampule helps to ensure that all the liquid is at the bottom, and placing a sterile gauze pad around the neck protects against glass shards. Breaking the top away from the body reduces the risk of injury and contamination.

D) Wear sterile gloves and break off the neck of the glass ampule with a single snap in a downward motion:
Breaking the ampule downward is not recommended because it can increase the risk of glass shards falling into the medication or causing injury. Proper technique involves breaking the ampule away from the body to ensure safety and avoid contamination.

Correct Answer is ["0.2"]

Explanation

Calculating the Morphine Sulfate Dose:Problem: Administer 2 mg of morphine sulfate IV bolus. The available concentration is 10 mg/mL.

Steps:

Set up a proportion:

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

We know the desired dose (2 mg) and the concentration of the medication (10 mg/mL).

Proportion:

x mL / 2 mg = 1 mL / 10 mg

Cross-multiply:

10x = 2

Solve for x:

x = 2 / 10

x = 0.2

Answer: The nurse should administer 0.2 mL of morphine sulfate per dose.
