Order: lidocaine 2 g in 250 mL of D5W at 30 mL/h
What is the flow rate?

A.

250 mL/hr

B.

30 mL/hr

C.

15 mL/hr

D.

150 mL/hr

E.

150 mL/hr

Answer and Explanation

The Correct Answer is B

The order directly states that the infusion rate is 30 mL/hr.

The information about the amount of Lidocaine (2 g) and the volume of D5W (250 mL) is irrelevant to determining the flow rate in this case.

The flow rate is already specified as 30 mL/hr in the order.

Correct Answer is A

Explanation

A) 0.2 mg
The correct way to write the dosage is 0.2 mg. In pharmacology and medication administration, it is important to follow the guidelines set by the Institute for Safe Medication Practices (ISMP) and other standard bodies, which recommend that a leading zero be used before a decimal point. This helps to prevent errors in interpreting the dosage. Writing 0.2 mg clearly indicates two-tenths of a milligram, and the leading zero makes it easier to avoid misreading the dose as a whole number (2.0 mg) or omitting the decimal point entirely.

B) .2 mg
Writing the dosage as .2 mg (without the leading zero) is considered unsafe and is a poor practice. The absence of the leading zero before the decimal point increases the likelihood that the dose may be misread. For example, someone could confuse .2 mg with 2.0 mg or misinterpret it in a hurried situation, which could lead to a tenfold dosing error

C) 2.0 mg
Writing 2.0 mg would indicate two milligrams, which is not the correct dosage for "two-tenths of a milligram." While this format does use a decimal point, it does not represent the correct dose. This error could lead to an overdose if misread as a whole number.

D) 0.20 mg
While 0.20 mg is technically correct, it is not the preferred or necessary format. The use of two decimal places is unnecessary in this case. Since the dosage is two-tenths of a milligram, 0.2 mg is simpler and clearer. Using an unnecessary trailing zero (the second "0") can cause confusion or misinterpretation, especially in critical settings where every detail counts.

Correct Answer is A

Explanation

Given:

Volume of fluid: 3,000 mL

Infusion time: 24 hours

Formula:

Flow rate (mL/hr) = Volume (mL) / Time (hr)

Step 1: Calculate the infusion rate in mL/hr:

Flow rate (mL/hr) = 3,000 mL / 24 hr

Flow rate (mL/hr) = 125 mL/hr
