• measurements, specifically pulse rate, temperature, respiration rate, and blood pressure, that indicate the state of a

  patient's essential body functions.

• not important or useful in determining a patients illness

• a specific procedure to make a discovery, test a hypothesis, or demonstrate a known fact.

• a proposed explanation based on some

A neurologist has information that leads her to suspect that a patient has a brain tumor.

What test should she order to confirm the diagnosis?

• A spinal tap to collect cerebrospinal fluid (CSF)

• Electromyography (EMG) tests

• Nerve conduction velocity tests

A patient comes to you with complaints of pain, tingling, and numbness in her left foot.

-The patient has no problems with movement.

-Brain scans, CSF, and EMG tests were all normal.

-Nerve conduction velocity tests were abnormal.

This information leads you to believe the problem is in the peripheral nervous system.

Given the choices below, which structure is the most likely location of the problem?

• Sensory neurons

• Brain

• Motor neurons

• Spinal cord

Based on the test results, what is the patient’s diagnosis?

• The patient does not have strep throat or influenza.

• The patient has both strep throat and influenza.

• The patient has influenza and not strep throat.
