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 D
Explanation
Saw palmetto is a natural herbal supplement that may help reduce the symptoms of benign prostate hypertrophy (BPH) by inhibiting the enzyme 5- alpha-reductase, which converts testosterone to dihydrotestosterone (DHT), a hormone that stimulates prostate growth. Some studies have shown that saw palmetto can improve urinary flow and reduce nocturia in men with BPH.
Choice Ais wrong because black cohosh is a plant that contains phytoestrogens, which are compounds that mimic estrogen in the body.Black cohosh is mainly used for menopausal symptoms in women, such as hot flashes and mood swings.
Choice Bis wrong because garlic has no proven effect on BPH. Garlic may have some benefits for cardiovascular health and immune system, but it does not affect prostate size or function.It has no effect on BPH and may even worsen it by altering the hormonal balance.
Choice C is wrong because feverfew is a herb that has anti-inflammatory and anti-migraine properties.
It may help prevent or treat headaches, arthritis, and allergies, but it has no effect on BPH or urinary symptoms.
Correct Answer is B
Explanation
Choice A rationale:
The air bubble should not be expelled from the syringe before administering enoxaparin. The air bubble is included to ensure that the entire dose is administered and to help prevent leakage of the medication into the subcutaneous tissue, which can reduce bruising.
Choice B rationale:
After administering enoxaparin, applying firm pressure (but not massaging) to the injection site helps minimize bruising and bleeding. It's important not to massage the site as this can increase the risk of bleeding.
Choice C rationale:
The needle should be inserted fully into the subcutaneous tissue at a 90-degree angle (or at a 45-degree angle if the client has little subcutaneous tissue). Inserting the needle halfway may result in improper administration.
Choice D rationale:
Enoxaparin is a low-molecular-weight heparin that should be administered subcutaneously, not intramuscularly. Administering it intramuscularly could increase the risk of bleeding and is not the appropriate route for this medication.
