Which of the following is a disadvantage of puncturing the radial artery?
Answer: C – The disadvantage of using the radial artery for arterial puncture is that it is smaller than other arteriesHowever, while other arteries may be larger, the advantages of the radial artery’s accessibility, proximity to the skin surface, and absence of nearby neural structures outweigh the disadvantages.
What happens if the radial artery is punctured?
thrombosis It is more common in the radial artery than in the brachial or femoral arteries. More likely if the arterial puncture is performed on a vessel with occlusive disease. Thrombosis may lead to ischemia and gangrene distal to the puncture.
What are the disadvantages of arterial blood collection?
Collection of arterial blood has its disadvantages. It is more difficult to obtain than venous or capillary blood samples, is more painful for the patient and can be potentially dangerous if proper procedures are not followed (1).
What would cause a patient to have no radial pulse after arterial puncture?
No pulse after catheterization may be due to Spasm, local thrombosis, endothelial flap formation, arterial dissection or avulsion.
Which is the second option for arterial puncture?
use brachial artery As a second option, unless there is dysrhythmia due to shock, obesity, or hardened blood vessels (eg, due to previous cardiac catheterization). The brachial artery is larger than the radial artery. Due to its proximity to the brachial artery, there is a risk of median nerve injury.

What is the preferred artery for ABG collection?
Radial artery is the preferred site. For arterial puncture in infants and children, small-gauge butterfly needles are preferable to needles and syringes used in adults.
What is a normal ABG?
The acceptable normal ranges of ABG values for ABG components are as follows,[6][7] Note that the range of normal values may vary by laboratory and in different age groups from neonates to elderly: pH (7.35-7.45) PaO2 (75-100 mmHg) PaCO2 (35-45 mmHg)

5. Clean the puncture site.use 70% isopropyl alcohol Do not clean the skin puncture site with iodine.
How deep is the radial artery?
The typical anterior wall of the radial artery is 3 mm subcutaneously, so Doesn’t need a lot of depth.
Can a punctured artery heal?
Whenever possible, doctors allow damaged arteries to heal on their own, instead of using invasive procedures to fix it. For some people, medicines may relieve symptoms of SCAD. In these cases, it can be treated with medication alone.
How to puncture the radial artery?
Use either puncture of the radial artery Micropuncture needle or cannula assembly on needle until arterial blood flashback is observed. Unsuccessful radial artery puncture usually results in radial artery spasm, temporary loss of radial pulse at the puncture site, and hematoma formation.
What happens if you shoot an artery?
hit an artery can be painful and dangerous. Arterial blood runs away from the heart, so anything injected goes directly to the extremities and extremities of the body. The injected particles get stuck in the capillaries and cut off the circulation. This can lead to insufficient blood flow and eventually tissue death.
Would you accidentally inject an IV into an artery?
One of the most horrific complications of the process is unintentional Intra-arterial cannulation. This can lead to accidental injection of the drug into the artery, which can have life-changing consequences.

- When you start digging, you will feel the pain like an electric shock.
- You will feel a sudden cramping pain when the needle touches the artery.
- The blood is pink or bright red when backed up.

What is the treatment for blocked arteries in the legs?
Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to your legs. Fatty deposits can build up in arteries and block blood flow. Stents are small metal mesh tubes that keep arteries open. Angioplasty and stenting are two methods of opening blocked peripheral arteries.
Why do patients need an arterial catheter?
Arterial catheters are often used in intensive care.them Allows us to easily draw blood without stabbing patients with needles. They also allow us to perform blood tests (such as arterial blood gases) that must be drawn from arteries. Arterial lines are also used when blood pressure needs to be closely monitored.
Who needs an arterial catheter?
Indications for placement of an arterial catheter include: (1) Continuous beat-to-beat monitoring of blood pressure in hemodynamically unstable patients(2) frequent blood collection for laboratory analysis, and (3) timing of intra-aortic balloon pump versus cardiac cycle.
