What does catheterization primarily involve?

Catheterization primarily involves the insertion of a tube, known as a catheter, to drain the bladder. This medical procedure is commonly performed in cases where a patient is unable to urinate on their own due to various medical conditions or surgical procedures. The catheter allows for the safe and effective removal of urine from the bladder, which helps prevent complications such as urinary tract infections or bladder over-distension.

The procedure is generally straightforward and can be performed in various settings, including hospitals, outpatient clinics, or even at home. It requires proper hygiene and technique to minimize the risk of infection. The use of catheters is important in many medical situations, such as post-surgery recovery, conditions like urinary retention, or for patients with certain neurological disorders.

While the other options involve medical procedures or functions, they do not accurately define catheterization. For instance, extraction of bodily fluids refers to a different set of procedures, monitoring vital signs involves observing physiological parameters, and administering medication relates to delivering drugs in various forms. All these functions serve distinct purposes that do not encompass the specific definition and application of catheterization.
