At 9:00 a.m. a nurse starts an intravenous (IV) infusion for a client at the rate of 120 mL/hr. If the volume of the fluid is 0.75 L, when will this infusion be completed?
3:01 p.m.
3:15 p.m.
3:25 p.m.
3:45 p.m.
The Correct Answer is B
We can use the formula for calculating infusion time:. Infusion time = Total volume / Infusion rate.
First, we need to convert the volume of the fluid from liters to milliliters:.
0.75 L = 750 mL.
Next, we can plug in the values we have:. Infusion time = 750 mL / 120 mL/hr.
Infusion time = 6.25 hours.
Since the infusion was started at 9:00 a.m., we can add 6.25 hours to determine when the infusion will be completed:.
9:00 a.m. + 6.25 hours = 3:15 p.m..
Therefore, the infusion will be completed at 3:15 p.m.

Correct Answer is D
Explanation
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
We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.
275/X = 500/2.
Cross-multiplying, we get:. 500X = 275 x 2.
X = (275 x 2)/500. X = 1.1 mL.
Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.
