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 B
Explanation
According to the CDC, people with severe, life-threatening allergies to any ingredient in a flu vaccine (other than egg proteins) should not get that vaccine. However, people with egg allergy can get a flu vaccine. The CDC also states that people who have had a severe allergic reaction to a dose of influenza vaccine should not get that flu vaccine again and might not be able to receive other influenza vaccines. Therefore, a nurse should report an egg allergy to the provider as a possible contraindication to receiving the vaccine.
Choice A is wrong because shellfish is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice C is wrong because milk is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice D is wrong because peanuts are not an ingredient in a flu vaccine and are not a contraindication to receiving the vaccine.
Correct Answer is A
Explanation
This is because fentanyl transmucosal is a fast-acting opioid that can be used for breakthrough pain in patients who are already receiving opioids for chronic pain. Breakthrough pain is a sudden and severe increase in pain that occurs despite the use of regular pain medication. Fentanyl transmucosal has a rapid onset of action (1-3 minutes) and a short duration of effect (1-2 hours), which makes it suitable for treating episodic pain.
Choice B. Lidocaine patch is wrong because lidocaine patch is a topical anesthetic that can be used for localized neuropathic pain, but not for acute or severe pain.
Choice C. Morphine tablet is wrong because morphine tablet is a long-acting opioid that can be used for chronic pain, but not for breakthrough pain. Morphine tablet has a slow onset of action (30-60 minutes) and a long duration of effect (3-4 hours), which makes it unsuitable for treating episodic pain.
Choice D. Naloxone IV is wrong because naloxone IV is an opioid antagonist that can reverse the effects of opioids, but not relieve pain.
