A nurse is assessing a client who is experiencing hypovolemia.

Which of the following manifestations should the nurse expect

The correct answer is B.

Choice A reason: Completing oral hygiene is important for overall health, especially for individuals with cystic fibrosis, as they are at a higher risk for dental problems due to thick mucus that can harbor bacteria. However, oral hygiene does not have a direct impact on the effectiveness of postural drainage. Postural drainage is a technique used to clear mucus from the lungs, and while maintaining oral hygiene is beneficial, it is not a prerequisite for this procedure.

Choice B reason: Using a bronchodilator, such as an ibuterol inhaler, is recommended before postural drainage because it helps to open the airways, making the procedure more effective. Bronchodilators work by relaxing the muscles around the airways, which can become constricted in conditions like cystic fibrosis. This relaxation allows for easier clearance of mucus during postural drainage.

Choice C reason: Pancrelipase is an enzyme supplement used to aid digestion in patients with cystic fibrosis, who often have pancreatic insufficiency. While taking pancrelipase is crucial for nutrient absorption, it is not specifically related to the respiratory treatment of postural drainage. Therefore, it is not necessary to take pancrelipase immediately before this procedure.

Choice D reason: Eating a meal before postural drainage is not recommended. The procedure involves placing the body in positions that facilitate the drainage of mucus from the lungs due to gravity. Having a full stomach can cause discomfort, increase the risk of vomiting, and may hinder the effectiveness of the drainage. It is best to perform postural drainage when the stomach is empty, either before meals or at least 1.5 hours after eating.

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.
