Vetinerary Assistant Practice Exam

Cystocentesis is defined as a procedure in which a needle is inserted into the bladder to remove urine. This technique is commonly used in veterinary medicine to obtain a sterile urine sample for diagnostic purposes, such as testing for infections or assessing kidney function. The procedure is often performed with the aid of ultrasound to ensure accurate placement of the needle and to minimize discomfort for the animal.

The other choices represent different medical procedures or concepts that do not relate to cystocentesis. For instance, removing the uterus refers to an ovariohysterectomy, which is a surgical procedure unrelated to urine removal. The examination of the esophagus pertains to esophagoscopy, a diagnostic procedure used to visualize the esophagus, while the term that describes the direction going up through the abdomen does not reflect a specific medical procedure at all. Thus, the description of a cystocentesis as a puncture to the bladder with a needle to remove urine clearly identifies the correct answer.
