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 B
Explanation
The amount of solution the nurse should withdraw from the vial can be calculated using the following formula:
Amount of solution = Amount of medication needed / Concentration of medication in the solution.
In this case, the amount of medication needed is 17.1 mg and the concentration of medication in the solution is 3 mg/mL. Substituting these values into the formula, we get:
Amount of solution = 17.1 mg / 3 mg/mL = 5.7 mL
Therefore, the answer is B. The nurse should withdraw 5.7 mL of solution from the vial.
Correct Answer is B
Explanation
To calculate the flow rate in mL/hr for a continuous infusion, we need to divide the total volume to be infused by the total time of infusion, and then convert the units as necessary.
In this case, the total volume is 2.5 L, which is equivalent to 2500 mL (1 L = 1000 mL), and the total time is 15 hours.
Flow rate = Total volume to be infused / Total time of infusion Flow rate = 2500 mL / 15 hours
Flow rate = 166.67 mL/hr
Therefore, the flow rate for continuous infusion of 0.9% sodium chloride solution in this case is 166.67 mL/hr.
