Correct Answer is D

Explanation

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 D

Explanation

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

6oz×29.5735mL/oz=177.441mL6

Calculate the frequency of doses per day:

The patient receives a dose every 4 hours, so in 24 hours, the number of doses is:

24hours/4hours/dose=6doses

Calculate the total volume for all doses:

177.441mL/dose×6doses=1064.646mL

Rounding to the nearest whole number=1080 mL
