Cerebellar function is assessed by which of the following tests?

Correct Answer: C

Rationale: Cerebellar function is assessed by testing coordination, balance, and fine motor skills. Asking the patient to hop on one foot evaluates their balance and coordination, which are controlled by the cerebellum. Muscle size and strength, cranial nerve examination, and the spinothalamic tract are not specific to cerebellar function.

Correct Answer: D

Rationale: Neurons form synapses with other neurons to create complex neural circuits. These synapses differ from neuromuscular junctions in their structure and function, often involving specialized cell-cell adhesion molecules and signaling mechanisms that enable precise communication between neurons.

Correct Answer: B

Rationale: Bacterial meningitis is characterized by cloudy CSF due to the presence of white blood cells, elevated protein levels, and decreased glucose levels. These findings result from the inflammatory response to bacterial infection in the meninges. Confirming these results is critical for initiating appropriate antibiotic therapy.

Correct Answer: B

Rationale: The tectum is part of the midbrain and is involved in auditory and visual reflexes. It includes structures like the superior and inferior colliculi, which play roles in processing sensory information.

Correct Answer: C

Rationale: The Glasgow Coma Scale (GCS) is the most important assessment for evaluating the level of consciousness in a patient with a head injury. The Babinski and Romberg tests assess motor function and balance, while the visual analogue scale measures pain. The GCS provides critical information about the patient's neurological status.
