A patient is ordered Amoxil (amoxicillin) 0.5 grams by mouth three times per day. The concentration is 125 mg/5 mL.
How many milliliters per dose should the nurse administer to the patient?
5 mL
10 mL
15 mL
20 mL
The Correct Answer is D
The patient is ordered to receive 0.5 grams of amoxicillin three times per day, which is equivalent to 500 mg per dose.
The concentration of amoxicillin is 125 mg/5 mL, which means there is 125 mg of amoxicillin in 5 mL of solution. To calculate how many milliliters per dose the nurse should administer, we can use the following formula:
500 mg / 125 mg per 5 mL = X mL X = 20 mL per dose
Amoxicillin is a type of antibiotic that belongs to the penicillin group of drugs. It is used to treat various bacterial infections, such as ear infections, sinus infections, throat infections, urinary tract infections, and skin infections. Amoxicillin works by interfering with the cell wall synthesis of bacteria, causing them to die or stop growing. Amoxicillin can also be used in combination with other drugs to treat stomach ulcers caused by Helicobacter pylori bacteria.

Correct Answer is C
Explanation
To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.
Total infusion time = Total volume to be infused / Infusion rate.
In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.
Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.
Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.
Correct Answer is B
Explanation
To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.
30 lb / 2.205 = 13.61 kg.
Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.
Dose (in mcg) = 136.1 mcg.
Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.
1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.
Cross-multiplying, we get:. 1X = 136.1 x 1.
X = 136.1 mL.
Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
