A client is receiving a secondary IV infusion of potassium chloride (KCI) 30 mEq at a rate of 10 mEq an hour. The pharmacy dispenses a 100 mL of 0.9% normal saline (NS) containing KCI 30 mEq. The nurse should program the infusion pump to deliver how many mL/hour (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["33"]

Rationale:

Given:

Total dose of Potassium Chloride: 30 mEq

Volume of solution: 100 mL

Infusion rate: 10 mEq/hour

Step 1: Determine the concentration of Potassium Chloride in the solution:

Concentration (mEq/mL) = Total Potassium Chloride (mEq) / Volume of solution (mL)

Concentration (mEq/mL) = 30 mEq / 100 mL

Concentration (mEq/mL) = 0.3 mEq/mL

Step 2: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Infusion rate (mEq/hr) / Concentration (mEq/mL)

Infusion rate (mL/hr) = 10 mEq/hr / 0.3 mEq/mL

Infusion rate (mL/hr) = 33.33 mL/hr

Step 3: Round to the nearest whole number:

Infusion rate (mL/hr) ≈ 33 mL/hr

Correct Answer is ["17"]

Explanation

Given:

Volume of fluid: 50 mL

Infusion time: 30 minutes

Drop factor: 10 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

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

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 50 mL / 30 min

Infusion rate (mL/min) = 1.67 mL/min

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 1.67 mL/min x 10 gtt/mL

Flow rate (gtt/min) = 16.7 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 17 gtt/min

Correct Answer is ["1.5"]

Explanation

Given:

Ordered dose of Ketorolac: 45 mg IM every 6 hours

Concentration of Ketorolac: 30 mg/mL

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

45 mg / Volume = 30 mg/mL

Step 3: Solve for the unknown volume:

Volume = 45 mg / (30 mg/mL)

Volume = 45 mg x (1 mL / 30 mg)

Volume = 1.5 mL
