A client requires a combined dose of regular and NPH insulin for morning glycemic control. What is the correct sequence of actions for drawing up these medications into a single syringe? Arrange the steps in chronological order.

  1. 1Inject a volume of air equal to the prescribed dose into the NPH insulin vial.
  2. 2Inject a volume of air equal to the prescribed dose into the regular insulin vial.
  3. 3Invert the vial and withdraw the prescribed dose of regular insulin.
  4. 4Insert the needle into the NPH vial and withdraw the prescribed dose.

Cevap

The correct sequence is: inject air into NPH, inject air into regular, draw up regular, and finally draw up NPH insulin.
When mixing NPH (cloudy) and regular (clear) insulin, the 'clear before cloudy' rule is strictly followed to prevent contamination of the short-acting regular insulin with the longer-acting NPH insulin. The sequence ensures air is placed in both vials to equalize pressure before drawing up the clear medication first, followed by the cloudy medication.

Adım Adım Çözüm

1
Inject air into the NPH insulin vial.
Pressure is equalized in the NPH vial.
Prevents vacuum formation when withdrawing medication later without contaminating the needle.
2
Inject air into the regular insulin vial.
Pressure is equalized in the regular insulin vial.
Prepares the vial for immediate withdrawal of the medication.
3
Withdraw the regular insulin.
The short-acting, clear insulin enters the syringe first.
Prevents contamination of the short-acting insulin vial with intermediate-acting insulin.
4
Withdraw the NPH insulin.
The intermediate-acting, cloudy insulin is added to the syringe to reach the total combined dose.
Completes the combined dose safely.
