A nurse is preparing to insert an IV catheter for a client. Which of the following actions should the nurse plan to take?
Select a site on the client’s dominant arm.
Apply a tourniquet below the venipuncture site.
Elevate the client’s arm prior to insertion.
Choose a vein that is palpable and straight.
The Correct Answer is D
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.

Correct Answer is B
Explanation
This is because rubella is a highly contagious viral infection that can cause serious harm to the developing fetus if the pregnant person gets infected. Rubella can cause congenital rubella syndrome, which can result in hearing and vision loss, heart defects and other serious conditions in newborns.
Choice A is wrong because aspirin should not be given to children or adolescents with viral infections, as it can cause Reye’s syndrome, a rare but potentially fatal condition that affects the liver and brain.
Choice C is wrong because rubella does not require airborne precautions, which are used for diseases that can spread through very small droplets that can remain in the air for long periods of time, such as tuberculosis or measles. Rubella spreads through direct contact with saliva or mucus of an infected person, or through respiratory droplets from coughing or sneezing.
Therefore, standard and droplet precautions are sufficient to prevent transmission. Choice D is wrong because Koplik spots are a characteristic sign of measles, not rubella.
Koplik spots are small white spots that appear on the inside of the cheeks before the measles rash develops. Rubella causes a pink or red rash that usually starts on the face and moves down the body.
Normal ranges for rubella antibody tests are:
- IgM: Negative or less than 0.9 IU/mL
- IgG: Negative or less than 10 IU/mL
A positive IgM result indicates a recent or current infection, while a positive IgG result indicates a past infection or immunity from vaccination.
Correct Answer is C
Explanation
This indicates that the child may be experiencing hemorrhage because they are trying to clear the blood from their throat. Frequent swallowing is one of the initial signs of bleeding immediately after tonsillectomy.
Choice A is wrong because elevated pain level is not a specific sign of hemorrhage. Pain is expected after a tonsillectomy and can be managed with medication and fluids.
Choice B is wrong because increased drowsiness is not a specific sign of hemorrhage. Drowsiness can be caused by anesthesia, medication, or dehydration.
Choice D is wrong because diminished breath sounds are not a specific sign of hemorrhage. Diminished breath sounds can be caused by respiratory infection, asthma, or bronchospasm.
Normal ranges for hemoglobin and hematocrit are 11.5 to 15.5 g/dL and 34 to 45% for children, respectively.
Normal ranges for platelet count are 150,000 to 450,000/mm3 for both children and adults. Normal ranges for plasma clotting variables depend on the specific test and method used.
