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.

Answer and Explanation

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 B

Explanation

Choice A rationale:

Hydrochlorothiazide is a diuretic medication and does not interfere with the absorption of tetracycline.

Choice B rationale:

Antacids can interfere with the absorption of tetracycline, reducing its effectiveness. Therefore, they should be taken 3 hours before or after taking tetracycline.

Choice C rationale:

Lovastatin is a lipid-lowering medication and does not interfere with the absorption of tetracycline.

Choice D rationale:

Acetaminophen is an analgesic and does not interfere with the absorption of tetracycline.

A. Renal excretion time slows for medication. B. Hepatic enzymes process medications more rapidly. C. Brain receptors become less sensitive to medications. D. Gastric emptying rate increases.

Correct Answer is A

Explanation

Choice A rationale:

Renal excretion time slows for medication. As people age, kidney function gradually decreases, which slows the excretion of medications. This can lead to increased levels of the drug in the body, which can increase the risk of side effects.

Choice B rationale:

Hepatic enzymes do not process medications more rapidly in older adults. In fact, liver function also decreases with age, which can slow the metabolism of medications.

Choice C rationale:

Brain receptors do not become less sensitive to medications in older adults. The sensitivity of brain receptors to medications can vary widely and is not necessarily related to age.

Choice D rationale:

Gastric emptying rate does not increase with age. On the contrary, it often slows down, which can affect the absorption of some medications.
