A nurse is caring for a client who is taking digoxin to treat heart failure. Which of the following factors predisposes this client to developing digoxin toxicity?

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.

This will help reduce swelling and discomfort caused by the infiltration of fluid into the tissues. Elevating the extremity also promotes venous return and prevents further fluid accumulation.

Choice A is wrong because applying pressure to the IV site can increase the risk of tissue damage and infection.

Pressure can also obstruct blood flow and cause thrombophlebitis.

Choice C is wrong because slowing the infusion rate will not stop the infiltration of fluid into the tissues.

Slowing the infusion rate can also delay the delivery of medication or fluid to the client.

Choice D is wrong because flushing the IV catheter can worsen the infiltration of fluid into the tissues.

Flushing the IV catheter can also introduce air or bacteria into the bloodstream and cause complications.

Normal ranges for peripheral IV infusion are dependent on the type and volume of fluid, the size and location of the catheter, and the condition of the client. Generally, peripheral IV infusion rates should not exceed 100 mL/hr for adults and 60 mL/hr for children.
