Haldol (haloperidol) 5.0 mg PO tid was ordered for a patient who is agitated.
Which action should a nurse take before administering the medication?
Discuss the use of PO with the healthcare provider.
Discuss the use of tid with the healthcare provider.
Discuss the use of Haldol with the healthcare provider.
Discuss the use of the trailing zero with the healthcare provider.
The Correct Answer is D
This action should be taken by the nurse before administering the medication because the use of a trailing zero after a decimal point (5.0 mg) is a common cause of medication errors and should be avoided. A trailing zero may be misread or misinterpreted as a larger dose (50 mg) or omited altogether, resulting in a 10-fold overdose or underdose, respectively. For example, when prescriptions have been writen for "Coumadin 1.0 mg," patients have received 10 mg in error. Therefore, the nurse should clarify the intended dose with the healthcare provider and use the correct notation (5 mg) without a trailing zero.
The other options are not appropriate actions because:
a) Discussing the use of PO (by mouth) with the healthcare provider is not necessary, as PO is a standard route of administration for Haldol (haloperidol) and does not pose a risk of confusion or error.
b) Discussing the use of tid (three times a day) with the healthcare provider is not necessary, as tid is a standard frequency of administration for Haldol and does not pose a risk of confusion or error.
c) Discussing the use of Haldol with the healthcare provider is not relevant to the question, as Haldol is the prescribed medication for the patient who is agitated and does not need to be changed or questioned by the nurse.

Correct Answer is D
Explanation
To find the volume of fluid that will be left at 10:00 am, you need to calculate the following:
- The time elapsed in minutes from 8:45 am to 10:00 am using the formula: Time elapsed (min) = End time (min) - Start time (min)
- The volume of fluid infused in milliliters (mL) during the time elapsed using the formula: Volume infused (mL) = Flow rate (mL/min) x Time elapsed (min)
- The volume of fluid left in milliliters (mL) at 10:00 am using the formula: Volume left (mL) = Initial volume (mL) - Volume infused (mL)
First, use the formula for time elapsed to find how many minutes have passed from 8:45 am to 10:00 am:
Time elapsed (min) = End time (min) - Start time (min)
Since the end time is 10:00 am and the start time is 8:45 am, plug in these values into the formula:
Time elapsed (min) = 600 min - 525 min
Simplify and solve for the time elapsed:
Time elapsed (min) = 75 min
Next, use the formula for volume infused to find the amount of fluid infused in milliliters during the time elapsed:
Volume infused (mL) = Flow rate (mL/min) x Time elapsed (min)
Since the flow rate is 2 mL/min and the time elapsed is 75 min, plug in these values into the formula:
Volume infused (mL) = 2 mL/min x 75 min
Simplify and solve for the volume infused:
Volume infused (mL) = 150 mL
Then, use the formula for volume left to find the amount of fluid left in milliliters at 10:00 am:
Volume left (mL) = Initial volume (mL) - Volume infused (mL)
Since the initial volume is 1500 mL and the volume infused is 150 mL, plug in these values into the formula:
Volume left (mL) = 1500 mL - 150 mL
Simplify and solve for the volume left:
Volume left (mL) = 1350 mL
Therefore, the volume of fluid that will be left at 10:00 am is **1350 mL**.
