A client who has heart failure with paroxysmal atrial tachycardia is receiving digoxin (Lanoxin) 0.45 mg IV as the initial digitalizing dose. The pharmacy provides 0.25 mg/ml. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.8"]
To calculate the volume of digoxin to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 0.45 mg / 0.25 mg/mL
Calculating the result:
Volume (mL) = 1.8 mL
Therefore, the nurse should administer 1.8 mL of digoxin.

Correct Answer is ["1"]
Explanation
To calculate the number of capsules needed, we'll first convert grams to milligrams:
0.1 grams x 1000 mg/gram = 100 mg
Then, we can set up a proportion:
x capsules / 100 mg = 1 capsule / 100 mg
Cross-multiplying:
100x = 100
Solving for x:
x = 100 / 100
x = 1
Therefore, the nurse should administer 1 capsule of Dantrolene.
Correct Answer is ["160"]
Explanation
Calculate the average hourly NGT output:
Average Hourly NGT Output = Total NGT Output / Number of Hours
Average Hourly NGT Output = 240 mL / 4 hours
Average Hourly NGT Output = 60 mL/hour
Adjust the IV rate:
New IV Rate = Current IV Rate + Average Hourly NGT Output
New IV Rate = 100 mL/hour + 60 mL/hour
New IV Rate = 160 mL/hour
Therefore, the nurse should regulate the IV to deliver 160 mL/hour to replace the fluid loss.
