A nurse is assessing a client who is experiencing hypovolemia. Which of the following manifestations should the nurse expect?

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.

This test should be performed after your baby is 24 hours old. This is because newborn genetic screening is a set of laboratory tests that detect a set of known genetic diseases that can affect a child’s long-term health or survival. The test is performed on a blood sample obtained from a heel prick when the baby is two or three days old. Performing the test after 24 hours ensures that the baby has had enough time to metabolize certain substances that could interfere with the accuracy of the test.

Choice A is wrong because the blood sample is not drawn from the baby’s inner elbow, but from the heel.

Choice B is wrong because the baby does not need to drink water prior to the test, as this could dilute the blood sample and affect the results.

Choice C is wrong because the test does not need to be repeated when the baby is 2 months old, unless there is a positive or inconclusive result from the first test.

Newborn genetic screening is important for early detection and intervention of certain conditions that can cause serious health problems or disability if left untreated. Parents should be informed about the benefits and limitations of the test, as well as their rights and options regarding consent and confidentiality.
