A nurse is mixing regular insulin and NPH insulin in the same syringe prior to administering it to a client who has diabetes mellitus.
Which of the following actions should the nurse take first?
Inject air into the NPH vial.
Withdraw the NPH insulin from the vial.
Withdraw the regular insulin from the vial.
Inject air into the regular insulin vial.
The Correct Answer is A
The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:
-
Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
-
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
-
Withdraw the regular insulin from the vial : The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
-
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.
This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

Correct Answer is ["A","B"]
Explanation
Fluticasone is an inhaled steroid that prevents the symptoms of asthma by decreasing inflammation in the airways. It is not used to treat a sudden asthma attack.
Some additional information to explain why the other choices are wrong are:
Choice C is wrong because soaking the inhaler in water after use can damage the device and affect its performance.
Choice D is wrong because fluticasone is not a rescue inhaler that can be used as needed for shortness of breath.It is a controller inhaler that should be used regularly as prescribed by the doctor.
Choice E is wrong because shaking the device prior to administration is not necessary for a fluticasone metered-dose inhaler (MDI).However, it is recommended for fluticasone inhalation powder (Flovent Diskus). Some normal ranges that may be applicable are:
The usual dose of fluticasone MDI for adults and children 12 years and older is 55 to 232 mcg twice a day.The usual dose of fluticasone MDI for children 4 to 11 years old is 30 mcg twice a day. The maximum dose of fluticasone MDI for adults and children 12 years and older is 1000 mcg twice a day.
Correct Answer is D
Explanation
The correct answer is d. Administer the medication over 2 hr.
Choice A reason: Discarding the medication if it is yellow is not necessary. The color of amphotericin B lipid complex does not indicate its effectiveness or safety.
Choice B reason: Using a gravity flow set is not specifically required for the administration of amphotericin B lipid complex. Gravity infusion can be used to administer fluids and drugs where the rate is not critical and serious adverse effects are not anticipated. However, the use of a gravity flow set is not specifically mentioned in the guidelines for administering amphotericin B lipid complex.
Choice C reason: Priming the tubing with 0.9% sodium chloride is not recommended for amphotericin B lipid complex. This is because amphotericin B lipid complex is incompatible with saline solutions and should be diluted only with 5% dextrose injection. Priming the tubing is a common practice in IV therapy to remove air from the tubing before attaching it to the patient.
Choice D reason: Administering the medication over 2 hr is the correct action. Amphotericin B lipid complex is typically administered over a longer period, often 2-6 hours. This allows for a slow and steady delivery of the medication, which can help to minimize potential side effects.
