A client is receiving an intravenous infusion of 1.5 L saline solution at a rate of 75 mL/hr. How many hours
will it take to finish the infusion at the current rate?
10 hours
7.5 hours
15 hours
20 hours
20 hours
The Correct Answer is C
The client is receiving an intravenous infusion of 1.5 L saline solution at a rate of 75 mL/hr. Since 1 L = 1000 mL, the total volume of the infusion is 1.5 L x 1000 mL/L = 1500 mL. At a rate of 75 mL/hr, it will take the client 1500 mL / 75 mL/hr = **15 hours** to finish the infusion.
A. 10 hours is not the correct answer because it does not account for the total volume of the infusion.
B. 7.5 hours is not the correct answer because it does not account for the total volume of the infusion.
d. 20 hours is not the correct answer because it does not account for the total volume of the infusion.

Correct Answer is A
Explanation
According to the Joint Commission's official "Do Not Use" list, QD (daily) is on the list because it can be mistaken for other abbreviations such as QOD (every other day). The period after the Q can be mistaken for "I" and the "O" can be mistaken for "I". Instead of using QD, it is recommended to write out "daily"¹.
Correct Answer is D
Explanation
The client is prescribed a dosage of 5 mg/kg of ipratropium every 12 hours. To calculate the appropriate daily dose for a 60 kg client, we can multiply the weight (60 kg) by the prescribed dosage (5 mg/kg):
60 kg * 5 mg/kg = 300 mg/day
The client reports taking 300 mg/day, which matches the prescribed dose. Therefore, the client is already taking the correct dose of ipratropium.
Based on this information, there is no need to double the dose (option a) or halve the dose (option b) because the client is already taking the prescribed amount.
Changing to an alternative medication (option c) would not be necessary as the client is effectively managing their asthma symptoms with the currently prescribed medication.
Thus, the appropriate instruction for the client is to continue the same dose of medication (option d) as prescribed.
