Which of these is an unexpected finding for a neurological system assessment?

Choice A reason: The left lower quadrant contains the sigmoid colon and parts of the small intestine, not the liver. Liver assessment involves palpation and percussion in the right upper quadrant, where it resides, making this choice incorrect for locating the liver anatomically.

Choice B reason: The liver is located in the right upper quadrant, beneath the diaphragm, extending slightly into the left upper quadrant. It is assessed via percussion and palpation in the RUQ to evaluate size or tenderness, making this the correct choice for liver localization.

Choice C reason: The left upper quadrant houses the stomach, spleen, and parts of the pancreas, not the liver’s primary location. While the liver’s left lobe extends slightly into the LUQ, its main mass is in the RUQ, making this choice incorrect.

Choice D reason: The right lower quadrant contains the appendix and cecum, not the liver. Liver assessment targets the right upper quadrant, where its bulk resides, making this choice incorrect for identifying the liver’s anatomical position during physical examination.

Choice A reason: Facial droop is an unexpected neurological finding, often indicating cranial nerve VII (facial nerve) dysfunction, as seen in stroke or Bell’s palsy. It disrupts symmetrical muscle movement, signaling potential brain or nerve pathology. This abnormality requires urgent evaluation to determine underlying causes like ischemia or inflammation.

Choice B reason: Swallowing without coughing is a normal finding, reflecting intact cranial nerves IX and X. Dysphagia or coughing during swallowing would suggest neurological impairment, but this choice indicates expected function, making it a typical result in a neurological assessment of swallowing capability.

Choice C reason: Spontaneous eye opening is a normal finding, indicating intact brainstem and cranial nerve function, particularly cranial nerve III. It is expected in conscious patients and does not suggest neurological dysfunction, unlike failure to open eyes, which could indicate coma or severe impairment.

Choice D reason: Understandable speech is a normal finding, reflecting coordinated function of cranial nerves and brain regions like Broca’s area. Slurred or incoherent speech would be abnormal, but this choice indicates expected neurological performance, not an unexpected outcome in a standard assessment.
