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 B
Explanation
To find the maximum number of tablets the patient may have in 24 hours, you need to calculate the following:
- The number of doses the patient may have in 24 hours using the formula: Number of doses = 24 hours / Dosing interval (hours)
- The total dose of ibuprofen in milligrams (mg) for 24 hours using the formula: Total dose (mg) = Number of doses x Prescribed dose (mg)
- The number of tablets of ibuprofen using the formula: Number of tablets = Total dose (mg) / Strength per tablet (mg)
First, use the formula for number of doses to find how many times the patient may take ibuprofen in 24 hours:
Number of doses = 24 hours / Dosing interval (hours)
Since the dosing interval is 6 hours, plug in this value into the formula:
Number of doses = 24 hours / 6 hours
Simplify and solve for the number of doses:
Number of doses = 4
Next, use the formula for total dose to find the amount of ibuprofen in milligrams for 24 hours:
Total dose (mg) = Number of doses x Prescribed dose (mg)
Since the number of doses is 4 and the prescribed dose is 600 mg, plug in these values into the formula:
Total dose (mg) = 4 x 600 mg
Simplify and solve for the total dose:
Total dose (mg) = 2400 mg
Then, use the formula for number of tablets to find how many tablets of ibuprofen are needed:
Number of tablets = Total dose (mg) / Strength per tablet (mg)
Since the total dose is 2400 mg and the strength per tablet is 200 mg, plug in these values into the formula:
Number of tablets = 2400 mg / 200 mg
Simplify and solve for the number of tablets:
Number of tablets = 12
Therefore, the maximum number of tablets the patient may have in 24 hours is **12**.
Correct Answer is C
Explanation
the correct rate to administer the maintenance dose is 50 mL/hr.
Step 1: Determine the concentration of magnesium sulfate in the solution.
- There are 40 grams of magnesium sulfate in 1 liter of solution.
- 1 liter = 1000 mL.
Step 2: Calculate the concentration in grams per mL.
- 40 grams ÷ 1000 mL = 0.04 grams per mL.
- Result: 0.04 grams per mL.
Step 3: Determine the required dose per hour.
- The physician ordered 2 grams per hour.
Step 4: Calculate the volume of solution needed to provide 2 grams of magnesium sulfate.
- Required dose (2 grams) ÷ concentration (0.04 grams per mL) = volume in mL.
- 2 grams ÷ 0.04 grams per mL = 50 mL.
- Result: 50 mL.
- The calculated rate is 50 mL/hr.
the correct rate to administer the maintenance dose is 50 mL/hr.
