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 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.

B, C, and E. The nurse should include the following statements in the teaching:.

• • You should eat foods that are low in fat. A low-fat diet can help reduce the amount of digestive enzymes your pancreas releases and prevent further inflammation and pain.
  • Notify your provider if you experience vomiting or diarrhea. These symptoms can lead to dehydration and malnutrition, which can worsen your condition and require hospitalization.
  • You should eat foods high in protein. Protein can help your body heal and repair damaged tissues. It can also prevent muscle wasting and weight loss, which are common complications of chronic pancreatitis.

Choice A is wrong because caffeine can stimulate the pancreas and increase pain and inflammation. Choice D is wrong because alcohol can damage the pancreas and trigger more attacks. People with chronic pancreatitis should avoid alcohol completely.
