A flexible, tubelike device for withdrawing or instilling fluids is a(n)Select one:a.catheter.b.electrolytes.c.urinal.d.stricture.

The correct answer to the question is:

a. catheter

Explanation:

A catheter is a medical device that consists of a flexible tube, which is inserted into the body to withdraw or instill fluids. Catheters serve various medical purposes, including draining urine from the bladder (urinary catheter), delivering medications directly into the bloodstream (intravenous catheter), and helping with surgeries. Their flexibility allows them to navigate through various bodily pathways without causing significant discomfort to the patient. Other options listed do not correctly fit the description provided. Electrolytes refer to substances that conduct electricity when dissolved in water, urinal is a container for urine, and stricture refers to an abnormal narrowing of a bodily passage or duct, rather than a device used for fluid management.
