When mixing NPH and regular insulin in a syringe, what is the correct sequence?
Mix both insulins in the vial before drawing them up.
It does not matter which insulin is drawn up first.
Draw up regular insulin first, then NPH insulin.
Draw up NPH insulin first, then regular insulin.
The Correct Answer is C
A. Mix both insulins in the vial before drawing them up: Mixing insulins directly in the vial is unsafe and can alter their pharmacokinetics, potentially causing unpredictable blood glucose control.
B. It does not matter which insulin is drawn up first: The order of drawing up insulins matters because improper sequence can contaminate the short-acting insulin with intermediate-acting insulin, affecting onset and duration of action.
C. Draw up regular insulin first, then NPH insulin: Regular insulin (short-acting) should always be drawn up before NPH insulin (intermediate-acting) to prevent contaminating the regular insulin with NPH, maintaining the intended onset and duration of both insulins.
D. Draw up NPH insulin first, then regular insulin: Drawing up NPH first increases the risk of contaminating the short-acting insulin with intermediate-acting insulin, which can delay its onset and compromise glycemic control.

Correct Answer is A
Explanation
Calculation:
Concentration: 200 mg/mL
Ordered Dose: 600 mg
- Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 600 ÷ 200
Volume to administer = 3 mL
Correct Answer is B
Explanation
A. Graduated cylinder and a funnel: While a graduated cylinder can measure liquid medications, a funnel is not practical for nasogastric tube administration and may increase the risk of spillage or contamination.
B. Syringe without a needle: A syringe without a needle is essential for safely delivering medications through a nasogastric tube. It allows controlled administration directly into the tube without causing injury or clogging.
C. Needle and syringe: Needles are not used for nasogastric tube administration because they can damage the tube and pose a risk of injury; medication should be delivered directly via the syringe.
D. Pill crusher and a stethoscope: A pill crusher may be used to prepare solid medications for tube administration, but a stethoscope is unnecessary for the act of administering medication itself. The syringe is the primary equipment needed.
