A patient is on a PCA pump following an abdominal surgery. The order states the client can have 0.5mg morphine every 15 minutes as needed. The client pushed the button 10 times in the past 60 minutes. How many doses did the client receive?
1
4
15
10
The Correct Answer is B
The PCA (patient-controlled analgesia) pump is programmed to deliver a dose of 0.5 mg of morphine every 15 minutes as needed. This setup means that only 1 dose can be administered every 15 minutes, regardless of how many times the patient presses the button.
Since 60 minutes have passed, the maximum number of doses the patient could receive is calculated as follows:
60 minutes/ 15 minutes per dose= 4 doses
Even though the patient pressed the button 10 times, the pump will only deliver a dose every 15 minutes, resulting in 4 doses.

Correct Answer is C
Explanation
The correct answer is choice C, Place all 4 side rails up to prevent the patient from getting out of bed and falling.
When considering alternatives to restraints for a confused and agitated patient who is at high risk for falls, placing all 4 side rails up to prevent the patient from getting out of bed and falling is not an appropriate alternative. This action can be considered as restraint use and can increase the patient's agitation and risk for injury. Instead, the nurse should provide the patient with activities to do while in bed, play music or video selections of the patient's choice, and reduce stimulation noise and light to calm the patient.
Correct Answer is ["0.2"]
Explanation
Each mL contains 5,000,000 units. Therefore, to administer 1,000,000 units, we need:
1,000,000 units / 5,000,000 units/mL = 0.2 mL
So, the nurse will give 0.2 mL of reconstituted penicillin G to the client.
