A nurse on a medical-surgical unit is notified that a mass casualty event has occurred in the community.

Which of the following actions should the nurse plan to take

The correct answer is choice C. Perform a sterile dressing change for a client who has an abdominal wound. This is because a licensed practical nurse (LPN) can perform tasks that require technical skills and have predictable outcomes, such as dressing changes. A sterile dressing change is also within the scope of practice of an LPN.

Choice A is wrong because complete discharge teaching for a client who has a new diagnosis of diabetes mellitus requires assessment, evaluation and critical thinking, which are beyond the scope of practice of an LPN. Discharge teaching is the responsibility of a registered nurse (RN) who can provide education and counseling to clients and families.

Choice B is wrong because completing the Glasgow Coma Scale for a client who has an evolving stroke requires assessment and interpretation of neurological status, which are complex and unpredictable tasks that only an RN can perform. The Glasgow Coma Scale is a tool that measures the level of consciousness of a client based on eye opening, verbal response and motor response. A client who has an evolving stroke may have changes in their neurological status that require frequent monitoring and intervention by an RN.

Choice D is wrong because performing an admission assessment for a client who is scheduled for surgery requires comprehensive data collection, analysis and synthesis, which are advanced skills that only an RN can perform. An admission assessment involves obtaining a complete health history, performing a physical examination, identifying client needs and problems, and developing a plan of care.

A client who is scheduled for surgery may have complex and unpredictable needs that require specialized knowledge and judgment by an RN.

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.
