For the right-sided cardiac catheterization, the catheter is inserted through?

Appeared in: UPRVUNL - 2021

Explanation

Right-sided cardiac catheterization is a procedure to evaluate the pressures and function of the right atrium, right ventricle, and pulmonary artery.
To reach the right side of the heart, the catheter must be introduced into the venous system, which carries deoxygenated blood back to the heart.
The femoral vein, located in the groin, is a large and common access site because it provides a direct path for the catheter to advance through the inferior vena cava and into the right heart chambers.

Option A: The term 'Carotid vein' is anatomically incorrect. The major vein in the neck is the internal jugular vein, while the carotid is a major artery. Arteries are not used for right-sided heart access.
Option B: The radial access site refers to the radial artery. Arterial access is the standard approach for left-sided cardiac catheterization to visualize the coronary arteries.
Option D: The umbilical vein is only patent and usable for vascular access in newborns during the first week of life. It is not a viable access site in older children or adults.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Venous access sites for right-sided cardiac catheterization as background academic context rather than a clinical decision trigger.
Post-procedure nursing care for femoral vein access is critical. Nurses must frequently monitor the insertion site for bleeding, hematoma formation, and signs of retroperitoneal hemorrhage (e.g., back pain, hypotension).
Assessing distal pulses, skin temperature, and color of the affected leg is essential to promptly detect any compromise in circulation, such as from a thrombus.
Patient education includes instructions to keep the affected leg straight for several hours and to limit activity as prescribed to prevent bleeding from the access site.

How to Approach the Question

First, identify the key phrase in the question: 'right-sided cardiac catheterization'.
Recall the fundamental principle of cardiac circulation: veins lead to the right side of the heart, and arteries lead away from the left side.
This principle dictates that a right-sided procedure must use a venous access point.
Evaluate the options based on whether they are veins or arteries and their common uses.
Eliminate 'Radial' as it refers to an artery used for left-sided procedures.
Eliminate 'Carotid vein' as it's an anatomically incorrect term; the carotid is an artery.
