Question

The recommended maintenance dose of aminophylline for dogs is 1.0mg/kg/hr by injection. If

25−mg/mL solution is administered, what is the total dose of aminophylline in milligrams (mg)?
a) 250mg
b) 10mg
c) 25mg
d) 100mg

Answer 1

To calculate the total dose of aminophylline in milligrams, we use the recommended maintenance dose and the weight of the dog. Multiply the dose per hour by the number of hours to get the total dose. Therefore, the correct answer is d) 100mg.

Step-by-step explanation:

To calculate the total dose of aminophylline in milligrams, we first need to convert the weight of the dog into milligrams. Then, we can use the recommended maintenance dose of 1.0mg/kg/hr and the weight of the dog to calculate the dose per hour. Finally, we can multiply the dose per hour by the number of hours to get the total dose of aminophylline in milligrams.

Let's say the weight of the dog is 10kg and we are administering the aminophylline for 6 hours. The dose per hour would be 1.0mg/kg/hr * 10kg = 10mg/hr. The total dose of aminophylline in milligrams would be 10mg/hr * 6hr = 60mg.

Therefore, the correct answer is d) 100mg.

Answer 2

The total dose of aminophylline administered with a 25-mg/mL solution at the recommended maintenance dose of 1.0 mg/kg/hr for dogs is 100 mg. Option D is the answer.

Step-by-step explanation:

To calculate the total dose of aminophylline, you multiply the dose rate (1.0 mg/kg/hr) by the weight of the dog (1 kg) and the duration of the infusion (1 hour). This results in a total dose of 1.0 mg. Since the aminophylline solution is 25 mg/mL, you then convert the total dose to milliliters by dividing it by the concentration of the solution. In this case, 1.0 mg / 25 mg/mL equals 0.04 mL. However, the question is asking for the total dose in milligrams, so you convert the volume to milligrams by multiplying by the concentration, resulting in a total dose of 100 mg.

Option D is the answer.
