Venipuncture- Clinical Skills Exam 1

The correct answer is Cubital fossa. The cubital fossa is a triangular depression on the anterior surface of the elbow joint. It is a common site for venipuncture, as it contains the median cubital vein, which is often used for drawing blood or administering intravenous medications. The other options mentioned (AF fossa, popliteal fossa, and dorsal vein) are not relevant to the context of venipuncture or the location of the cubital fossa.

The injection site for an IV should be changed every 4 days. This is because frequent site rotation helps prevent complications such as infection, infiltration, and phlebitis. By changing the site every 4 days, the risk of these complications is minimized, ensuring the safety and effectiveness of the IV therapy.

The question is asking for the vessel that is not commonly used for venipuncture. Venipuncture is the process of puncturing a vein to draw blood or administer medication. The basilic, median cubital, and cephalic veins are commonly used for venipuncture. However, the ethmoid is not a vessel that is typically used for this procedure. The ethmoid is actually a bone located in the skull, not a vein. Therefore, it is not one of the most common vessels for venipuncture.

After venipuncture, it is important to assess the patient for lightheadedness before leaving them. This is because the process of venipuncture can cause a drop in blood pressure, leading to lightheadedness or dizziness. By assessing for lightheadedness, healthcare professionals can ensure the patient's safety and provide any necessary interventions or support to prevent falls or other complications. Assessing for lightheadedness is a crucial step in the post-venipuncture care of a patient.

The appropriate size IV catheter for children is 24g, while for adults it is 16/18g. This means that for children, a smaller gauge size (24g) is needed compared to adults, who require a larger gauge size (16/18g). The gauge size refers to the diameter of the catheter, with a smaller number indicating a larger diameter. Therefore, the answer choice of 1) 24g for children and 2) 16/18g for adults is correct.

The most prominent veins in the triangular hollow area of an ant arm are the basilic and cephalic veins. These veins are easily visible and stand out in this area.

Not sure--- ppt said "nutritional components " is an indication so I'm assuming if you're deficient in X nutrient that is an indication for IV nutrition supplementation

After administering an injection, it is important to observe the patient for a certain period to monitor for any immediate adverse reactions or complications. The correct answer of 15 minutes suggests that this is the minimum recommended time for observation. During this time, any immediate side effects or allergic reactions can be identified and promptly addressed. This short observation period allows healthcare professionals to ensure the patient's safety and well-being before they leave the facility.

The risk of local infection from an IV catheter is increased if it is left in longer than 72-96 hours. This is because the longer the catheter remains in place, the higher the chances of bacteria entering the insertion site and causing an infection. It is important to remove the catheter within the recommended time frame to minimize the risk of complications.

The correct answer for this question is children. This is because children often have smaller veins and may require the use of a lower extremity for IV caths.

Aspiration is unnecessary for the IM injection type. Aspiration refers to the process of pulling back on the syringe plunger after inserting the needle to check if blood is drawn into the syringe. This is done to ensure that the needle has not accidentally punctured a blood vessel. However, in the case of IM injections, the needle is inserted into the muscle, away from major blood vessels. Therefore, the risk of accidentally puncturing a blood vessel is low, making aspiration unnecessary for IM injections.

The lateral marginal vessel is not commonly used in lower extremity IV catheters. This is because it is a smaller vessel located on the outer side of the leg, making it more difficult to access and potentially increasing the risk of complications during catheter insertion. The other options, including the lesser saphenous, greater saphenous, and medial marginal vessels, are more commonly used in lower extremity IV catheters due to their larger size and easier accessibility.

Lateral to medial

Hyaluronidase is given for IV contrast extravasation. This medication helps to break down hyaluronic acid, which is a substance that can cause tissue damage and inflammation when it leaks out of the blood vessels during extravasation. By administering hyaluronidase, it can help to disperse the contrast dye and prevent further damage to the surrounding tissues.

After removing the needle for venipuncture, it is recommended to apply pressure for 3-4 minutes. This is important to ensure that bleeding is controlled and a hematoma does not form at the puncture site. Applying pressure for this duration allows the blood vessels to seal properly and prevents excessive bleeding. Applying pressure for a shorter duration may not be sufficient to achieve hemostasis, while applying pressure for a longer duration may cause unnecessary discomfort to the patient. Therefore, 3-4 minutes is the appropriate time to apply pressure after removing the needle for venipuncture.
