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 B

Explanation

Calculate the dosage using the ratio and proportion:

Given:

Order: 200 mg p.o. t.i.d.

Available: Tegretol 100 mg chewable tablets.

Step 1: Set up the proportion

Availabledose(100mg) : 1tablet = Ordereddose(200mg) : xtablets

Step 2: Solve for 𝑥

100 mg : 1 tab = 200 mg : 𝑥 tabs

𝑥 = 200/100 = 2 tablets

Correct Answer is B

Explanation

Given:

Ordered dose of amoxicillin: 300 mg

Concentration of amoxicillin oral solution: 250 mg/5 mL

Step 1: Set up the proportion:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Step 2: Substitute the values:

300 mg / Volume = 250 mg/5 mL

Step 3: Solve for the unknown volume:

Volume = 300 mg / (250 mg/5 mL)

Volume = 300 mg x (5 mL / 250 mg)

Volume = 6 mL
