A nurse is providing discharge teaching to a client who is postoperative following the surgical repair of a detached retina.

Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is choice D. The nurse should choose a vein that is palpable and straight for IV catheter insertion.

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.

Choice A reason:

Determine previous coping skills used by the client is not appropriate. Assessing the client's previous coping skills is an essential step in the assessment phase of the therapeutic relationship, not specifically during the orientation phase. This information helps the nurse to understand the client's coping mechanisms and identify potential areas for improvement or support.

Choice B reason:

Facilitate the client's problem-solving skills is not appropriate the nurse may work on facilitating the client's problem-solving skills throughout the therapeutic relationship, including during the working phase. During this phase, the nurse and client collaborate to explore and address the client's concerns and challenges.

Choice Creason:

Assisting the client in expressing alternative behaviours is not appropriate. This action may also be part of the working phase, where the nurse helps the client explore alternative behaviours and coping strategies to address their issues and challenges.

Choice D reason:

The orientation phase is the initial stage of the therapeutic relationship where the nurse and the client get to know each other and establish the groundwork for their working relationship. During this phase, it is essential to clarify the roles and responsibilities of both the nurse and the client to ensure a clear understanding of each other's expectations.
