Vetinerary Assistant Practice Exam

In which recumbency should an animal be placed during a cystocentesis?

1. Ventral

2. Sternal

3. Lateral and dorsal

4. Prone

The correct answer is: Lateral and dorsal

During a cystocentesis, the animal is typically placed in either lateral or dorsal recumbency, making this the most appropriate choice. Lateral recumbency allows easy access to the bladder, particularly in animals where the urinary bladder is more palpable on one side. This position helps to stabilize the animal by using gravity to assist in locating the bladder and also minimizes movement, which is crucial during the procedure. In dorsal recumbency, the animal lies on its back, providing a clear view and access for the veterinary personnel. This position is useful especially in larger animals or those with a deeper abdominal cavity, as it can offer better access to the bladder. Each method has its applications based on the specific situation and the anatomy of the animal being treated. Other options, such as ventral recumbency or sternal, are less favorable for this procedure. Ventral recumbency, where the animal lies on its belly, does not provide adequate access to the bladder for needle insertion. Similarly, sternal recumbency, where the animal is upright on its chest, is not suitable as it complicates access to the abdominal area. Prone positioning, which typically refers to a face-down position, does not apply to standard veterinary practices for cyst
