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 ["60"]

Explanation

Given:

Ordered dose: 25 mL PO every 6 hours PRN

Medication label: "Acetaminophen and Codeine Phosphate Oral Solution, USP: 120/12 mg per 5 mL"

Step 1: Determine the concentration of codeine in the solution:

Concentration of Codeine = Amount of Codeine / Volume of Solution

Concentration of Codeine = 12 mg / 5 mL

Concentration of Codeine = 2.4 mg/mL

Step 2: Calculate the amount of codeine per dose:

Amount of Codeine per Dose = Concentration of Codeine x Volume per Dose

Amount of Codeine per Dose = 2.4 mg/mL x 25 mL

Amount of Codeine per Dose = 60 mg

Correct Answer is ["1.5"]

Explanation

Given:

Ordered loading dose of Heparin: 80 units/kg

Patient weight: 95 kg

Concentration of Heparin: 5,000 units/mL

Step 1: Calculate the total loading dose of Heparin:

Total loading dose (units) = Ordered dose (units/kg) x Patient weight (kg)

Total loading dose (units) = 80 units/kg x 95 kg

Total loading dose (units) = 7600 units

Step 2: Calculate the volume to be administered:

Volume (mL) = Total loading dose (units) / Concentration (units/mL)

Volume (mL) = 7600 units / 5000 units/mL

Volume (mL) = 1.52 mL

Step 3: Round to the nearest tenth:

Volume (mL) ≈ 1.5 mL
