Which product is the antidote for digitalis toxicity?

A.

Gamma globülin

B.

Cardizem

C.

Protamine

D.

Digoxin immune fab

Answer and Explanation

The Correct Answer is D

A) Gamma globulin
Gamma globulin is a blood product used to provide passive immunity by supplying antibodies to prevent or treat certain infections. It is not used for digitalis toxicity, so A is incorrect.

B) Cardizem
Cardizem (diltiazem) is a calcium channel blocker primarily used for controlling heart rate and treating conditions such as atrial fibrillation or angina. It is not used as an antidote for digoxin toxicity, so B is incorrect.

C) Protamine
Protamine is a medication used to reverse the effects of heparin, an anticoagulant. It works by neutralizing the anticoagulant activity of heparin, but it is not used to treat digitalis (digoxin) toxicity, so C is incorrect.

D) Digoxin immune fab
Digoxin immune fab is the specific antidote for digoxin toxicity. It consists of antibodies that bind to digoxin molecules, thereby neutralizing their toxic effects on the heart. This antidote is used when a patient exhibits severe symptoms of digoxin toxicity, such as arrhythmias or life-threatening effects on the heart. Therefore, D is the correct answer.

Correct Answer is C

Explanation

Convert ounces to milliliters (1 oz = 29.5735 mL):

8 oz coffee: 8 × 29.5735 = 236.588 mL

3 oz juice: 3 × 29.5735 = 88.7205 mL

12 oz soda: 12 × 29.5735 = 354.882 mL

Calculate the water intake from the water pitcher:

Total water intake: 800 mL (initial) - 200 mL (remaining) = 600 mL

Calculate the IV fluid intake:

IV fluids at 40 mL/hr for 8 hours: 40 × 8 = 320 mL

Add all the fluid amounts:

Totalfluidintake=236.588mL+88.7205mL+354.882mL+600mL+320mL=1600.1905mL

Rounding to the nearest whole number: 1600 mL.

Correct Answer is C

Explanation

Given:

Volume of fluid: 100 mL

Infusion time: 30 minutes

Drop factor: 60 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min) x Drop factor (gtt/mL)

Step 1: Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 100 mL / 30 min

Infusion rate (mL/min) = 3.33 mL/min

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 3.33 mL/min x 60 gtt/mL

Flow rate (gtt/min) = 200 gtt/min
