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.

Answer and Explanation

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 ﬂow rate in mL/hr, you need to use the formula for infusion rate:

Infusion rate (mL/h) = Total volume (mL) / Time (h)

Since the total volume is 2.5 L and the time is 15 hours, plug in these values into the formula:

Infusion rate (mL/h) = 2.5 L / 15 h

However, before you can simplify and solve for the infusion rate, you need to convert the volume from liters to milliliters by multiplying by 1000:

Infusion rate (mL/h) = 2500 mL / 15 h

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 166.67 mL/h

Therefore, the ﬂow rate for continuous infusion is **166.67 mL/h**.

A. 6 tablets B. 12 tablets C. 4 tablets D. 3 tablets

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**.
