A nurse is planning teaching for a client and their family about home oxygen therapy. Which of the following information should the nurse plan to include in the teaching?

The nurse should give the client one simple direction at a time, reinforce orientation to time, place, and person, and establish eye contact when communicating with the client.

These interventions can help the client with dementia to understand and follow instructions, reduce confusion and anxiety, and enhance communication.

Choice A is wrong because allowing the client to choose among a variety of activities each day can overwhelm and frustrate the client with dementia.

The nurse should provide a structured and consistent daily routine for the client.

Choice E is wrong because refuting the client’s delusions using logic can increase the client’s agitation and distrust.

The nurse should use validation therapy to acknowledge the client’s feelings and emotions without arguing or correcting the client.

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.
