A nurse is preparing to insert an IV catheter for a client. Which of the following actions should the nurse plan to take?

This will facilitate the insertion of the catheter and reduce the risk of complications such as infiltration, phlebitis, or hematoma. A straight vein will also allow the catheter to be inserted up to the hub, which reduces the risk of contamination along the length of the catheter.

Choice A is wrong because selecting a site on the client’s dominant arm can interfere with the client’s mobility and increase the risk of dislodging the catheter. The nurse should choose a site on the client’s non-dominant arm, preferably on the hand or forearm.

Choice B is wrong because applying a tourniquet below the venipuncture site will impede blood flow and make it harder to locate a suitable vein. The nurse should apply a tourniquet above the venipuncture site, about 10 to 15 cm from the insertion site.

Choice C is wrong because elevating the client’s arm prior to insertion will decrease venous filling and make it harder to palpate a vein. The nurse should lower the client’s arm below the level of the heart to increase venous distension.

Normal ranges for IV catheter size and insertion angle depend on several factors, such as the type and duration of therapy, the condition and size of the vein, and the age and preference of the client.

In general, smaller gauge catheters (20 to 24) are preferred for peripheral IV therapy, and larger gauge catheters (14 to 18) are used for rapid fluid administration or blood transfusion. The insertion angle can vary from 10 to 30 degrees, depending on the depth and location of the vein.

A healthcare surrogate is a person who is authorized to make healthcare decisions for a client who is unable to do so. The nurse has a legal and ethical responsibility to ensure that the client’s surrogate has given informed consent for the surgery, which means that they have received adequate information about the procedure, its purpose, its risks, its benefits, and its alternatives.
Choice A is wrong because sending the unsigned informed consent form to the facility’s risk manager does not ensure that the client’s surrogate has given informed consent. The risk manager is not involved in the consent process and cannot authorize the surgery without the surrogate’s consent.
Choice B is wrong because ensuring that the client’s family supports the provider’s decision for surgery is not the same as obtaining informed consent from the surrogate.

The family may have different opinions or preferences than the surrogate, and the surrogate may not agree with the provider’s decision. The nurse should respect the surrogate’s autonomy and authority to make decisions for the client.
Choice C is wrong because determining if the procedure is medically necessary for the client is not the nurse’s role.
The provider is responsible for determining the medical necessity of the surgery and explaining it to the surrogate. The nurse should not question or interfere with the provider’s judgment unless there is evidence of negligence or malpractice.
