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 the retention port is a sterile site that can be accessed by a syringe to aspirate urine without contaminating the specimen or the closed drainage system. The retention port should be cleaned with an alcohol swab before inserting the syringe. The specimen should be transferred to a sterile container and labeled appropriately.
Choice A is wrong because unclamping the collection port below the bag would allow urine to flow out of the bag, which is not sterile and may contain bacteria or sediment.
Choice C is wrong because disconnecting the catheter from the collection tubing would break the closed drainage system and increase the risk of infection.
Choice D is wrong because using the balloon port to obtain the sterile specimen would deflate the balloon that holds the catheter in place and cause trauma to the bladder wall.
Normal ranges for urine characteristics vary depending on the type of analysis, but some general parameters are:
• Color: pale yellow to amber
• Clarity: clear or slightly cloudy
• Odor: faint aromatic
• pH: 4.5 to 8.0
• Specific gravity: 1.005 to 1.030
• Protein: <150 mg/24 hr
• Glucose: negative
• Ketones: negative
• Blood: negative
• Nitrites: negative
• Leukocyte esterase: negative
• Bacteria: <10,000 CFU/mL
Correct Answer is B
Explanation
This is because epiglottitis is a life-threatening condition that can cause severe airway obstruction and respiratory distress in children. The nurse should monitor the child for signs of worsening breathing, such as stridor, cyanosis, restlessness, or drooling. The nurse should also be prepared to assist with intubation or tracheostomy if needed.
Choice A is wrong because assessing the child for frequent swallowing may increase the risk of vomiting and aspiration. Swallowing may also be difficult and painful for the child due to the inflammation of the epiglottis.
Choice C is wrong because suctioning the child’s oropharynx may cause more swelling and irritation of the epiglottis, or trigger a spasm that can close off the airway. The nurse should avoid any stimulation of the throat or mouth that may worsen the condition.
Choice D is wrong because administering pancreatic enzymes with meals is not relevant to epiglottitis. Pancreatic enzymes are used to treat cystic fibrosis, a genetic disorder that affects the lungs and digestive system. Epiglottitis is caused by a bacterial infection or an injury to the throat.
