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 A
Explanation
To calculate the dose of brentuximab in mg that the client should receive, we need to multiply the weight of the client in kg by the prescribed dose of 1.8 mg/kg:.
Dose (in mg) = Weight (in kg) x Dose (in mg/kg).
Dose (in mg) = 60 kg x 1.8 mg/kg. Dose (in mg) = 108 mg.
Now we need to calculate the volume of medication to administer. Since the medication available is 50 mg per 10 mL, we can use proportion to calculate the volume:.
50 mg is to 10 mL as 108 mg is to X mL. 50/10 = 108/X.
Cross-multiplying, we get:. 50X = 108 x 10.
X = (108 x 10)/50. X = 21.6 mL.
Therefore, the nurse should administer 21.6 mL of brentuximab to the client.
