A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?
Aspirate prior to injecting the medication.
Gently massage the site following the injection.
Expel the air bubble before injecting the medication.
Inject the medication into abdominal tissue.
The Correct Answer is D
Choice A rationale:
Aspiration (pulling back on the syringe before injection) is not recommended when administering enoxaparin. This could cause bruising.
Choice B rationale:
You should not massage the site following the injection as this could cause bruising.
Choice C rationale:
With enoxaparin and other low molecular weight heparins, you do not need to expel the air bubble before injecting the medication. The air bubble ensures that all the medication is delivered.
Choice D rationale:
Enoxaparin should be injected into abdominal tissue. This helps ensure proper absorption and reduces the risk of bruising.

Correct Answer is C
Explanation
Choice A rationale:
Dry mouth is a common side effect of diphenhydramine. Diphenhydramine is an antihistamine that is often used to treat allergies, insomnia, and symptoms of the common cold. It works by blocking the effects of histamine, a substance in the body that causes allergy symptoms. One of the effects of histamine is increased salivation, so when diphenhydramine blocks this effect, it can lead to dry mouth.
Choice B rationale:
Nausea is also a common side effect of diphenhydramine. This can occur because diphenhydramine can slow down the emptying of the stomach, leading to feelings of nausea. Additionally, diphenhydramine can affect the vestibular system in the inner ear, which can also lead to feelings of nausea.
Choice C rationale:
Agitation is considered an idiosyncratic reaction to diphenhydramine. An idiosyncratic reaction is an unusual or unexpected reaction to a drug that is not related to the usual pharmacological action of the drug. While diphenhydramine is typically used for its sedative effects, in some cases it can cause paradoxical central nervous system stimulation, leading to agitation.
Choice D rationale:
Dizziness is another common side effect of diphenhydramine. This occurs because diphenhydramine can affect the vestibular system in the inner ear, which plays a key role in maintaining balance. When this system is affected, it can lead to feelings of dizziness.
Correct Answer is B
Explanation
Choice A rationale:
While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.
Choice B rationale:
Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.
Choice C rationale:
Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.
Choice D rationale:
Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.
