To calculate the dose of a medication based on the client’s weight, the nurse should multiply the recommended dose by the client’s weight in kg. In this case, the recommended dose is 5 mg/kg and the client weighs 70 kg, so the nurse should administer 5 mg/kg x 70 kg = 350 mg of the medication.

b. The correct dose is 350 mg, not 300 mg.

c. The correct dose is 350 mg, not 250 mg.

d. The correct dose is 350 mg, not 200 mg.

To calculate the volume of a liquid medication to administer based on its concentration and the prescribed dose, the nurse should divide the prescribed dose by the concentration and multiply by the volume in which the concentration is expressed. In this case, the concentration is 250 mg/5 mL and the prescribed dose is 500 mg, so the nurse should administer (500 mg / 250 mg) x 5 mL = 10 mL of the medication.

a. The correct volume is 10 mL, not 5 mL.

c. The correct volume is 10 mL, not 15 mL.

d. The correct volume is 10 mL, not 20 mL.

Before administering an injection,the nurse should verify patient’s identity using two identifiers such as name and date of birth.The nurse should also check injection site for any signs of infection,inflammation or injury.Finally,the nurse should check patient’s allergies to ensure that they are not allergic to any component of injection being administered.

a.Verifying patient’s identity using two identifiers such as name and date of birth is important before administering an injection.

b.Checking injection site for any signs of infection,inflammation or injury is important before administering an injection.

c.Checking patient’s allergies to ensure that they are not allergic to any component of injection being administered is important before administering an injection.

Before administering an oral tablet to a patient who has difficulty swallowing,the nurse should consult with provider.Some tablets are designed to be swallowed whole and should not be crushed or cut as this may alter their pharmacokinetics.In such cases,alternative formulations such as liquid or chewable tablets may be available.

a.Crushing tablet and mixing with applesauce may alter pharmacokinetics and should only be done if approved by provider.

b.Cutting tablet in half may alter pharmacokinetics and should only be done if approved by provider.

c.Administering tablet with large glass of water may help patient swallow but does not address underlying difficulty.

To calculate drops per minute,the nurse should multiply infusion rate in mL/hr by drop factor in gtt/mL and divide by60min/hr.In this case,the infusion rate is125mL/hr and drop factor is15gtt/mL so,the nurse should deliver(125mL/hrx15gtt/mL)/60min/hr=31gtt/min.

To calculate infusion rate in mL/hr,the nurse should divide total volume in mL by total infusion time in hours.In this case,the total volume is1000mL and total infusion time is8hours so,the nurse should deliver1000mL/8hr=125mL/hr.

To calculate the dose of a medication based on client’s weight,the nurse should multiply recommended dose by client’s weight in kg.In this case,the recommended dose is2mg/kg and client weighs 60kg so,the nurse should administer2mg/kg x60kg=120mg of medication.

To calculate infusion rate in mL/hr,the nurse should divide total volume in mL by total infusion time in hours.In this case,the total volume is2000mL and total infusion time is12hours so,the nurse should deliver2000mL/12hr=166mL/hr.

To calculate infusion rate in mL/min,the nurse should divide total volume in mL by total infusion time in minutes.In this case,the total volume is6ml and total infusion time is3minutes so,the nurse should deliver6ml/3min=2ml/min.
