  1. So the PCA questions are back this semester...if someone could take a look at this and see if it's correct, I'd appreciate it.


    1. A patient has a PCA. It is delivering 3mg as a basal rate. The patient can have 1mg every 15 minutes on demand. What is the maximum amount of Morphine that a patient can have in a four hour period?

    3 mg/hr x (4 hours)=12 mg
    4 mg/hr x (4 hours)=16 mg

    Answer=28 mg/4 hours

    Correct =)

  4. Correct! Just remember that if a patient is receiving a basal rate, they are receiving that amount regardless of if they press the button. The basal rate is like a continuous infusion...no matter what, they will receive that amount per hour.
    So, for example, if the order is: 4mg/hour basal rate, 1mg with a lock-out time of 6 minutes...
    Total amount = Basal rate (4mg) + patient demand (60minutes/6minutes=10 demands; 10 demands x 1mg= 10mg)
    The patient would receive 14mg/hour maximum
  5. Thanks for the breakdown! Great example to print out and carry with me so I won't forget. Thanks everyone, I really appreciate all the help!
