A client diagnosed with schizophrenia is prescribed clozapine. The nurse teaches the client and family to call the physician immediately if:
A patient with fluid volume deficit must receive a 250 mL IV bolus of NS over 25 minutes via a peripherally inserted central line (PICC) on an IV pump. At what rate will the nurse program the pump? Round to the nearest whole number. Do not use trailing zeros.
Explanation
Step 1: Identify the total volume to be infused.
- Total volume = 250 mL
Step 2: Identify the total time for infusion.
- Total time = 25 minutes
Step 3: Calculate the rate in mL per minute.
- Rate = Total volume ÷ Total time
- Rate = 250 mL ÷ 25 minutes
- Rate = 10 mL per minute
Step 4: Convert the rate to mL per hour.
- Since there are 60 minutes in an hour, multiply the rate by 60.
- Rate per hour = 10 mL per minute × 60
- Rate per hour = 600 mL per hour
The nurse should program the pump to infuse at a rate of 600 mL per hour.
A nurse is caring for a client who has schizophrenia and is experiencing command auditory hallucinations. Which of the following actions should the nurse take?
A patient is prescribed morphine sulfate 5 mg IV every 4 hours as needed for a pain level greater than 7 on a scale of 0-10. Morphine is available in 8 mg/mL vials. How many mL will the nurse give for the correct dose?
Round to the nearest hundredth. Use a preceding zero if necessary. Do not use trailing zeros.
Explanation
To calculate the correct dose:
- Identify the prescribed dose: 5 mg
- Identify the concentration of the available morphine: 8 mg/mL
- Calculate the volume to be administered:
- Volume (mL) = Prescribed dose (mg) ÷ Concentration (mg/mL)
- Volume (mL) = 5 mg ÷ 8 mg/mL
- Volume (mL) = 0.625 mL
The nurse will give 0.63 mL (rounded to the nearest hundredth) for the correct dose.
