Answer and Explanation

The Correct Answer is A

Given:

Volume of fluid: 1 liter = 1000 mL

Infusion time: 6 hours

Drop factor: 10 gtt/mL

 

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

 

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

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

Infusion rate (mL/hr) = 1000 mL / 6 hr

Infusion rate (mL/hr) = 166.67 mL/hr

 

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

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (166.67 mL/hr x 10 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1666.7 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 27.78 gtt/min

 

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 28 gtt/min

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

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.
