Diagnosing
True or False: Diagnosing disease is a simple process that’s based entirely on a patient’s symptoms.
False
What manner of spread is spread by drinking contaminated water or food.
Foodborne
Which vital sign corresponds with the following definition: This body function is controlled by the hypothalamus portion of the brain, it makes sure you do not get too hot or too cold.
Temperature
What is the parietal lobe responsible for?
Sensing touch, spatial processing, language, and memory.
What is the formula for attack rate?
Number of sick people
___________________ x 100
Total # of people
What parts of your body make up the Central Nervous System?
Brain and Spinal Cord
This microorganism causes strep throat. It can multiply without a host. It can be treated with antibiotics. It is so small you would need to view it through a microscope at school.
What type of disease agent is this microorganism?
Bacteria
Which vital sign corresponds with the following definition: The number of breaths a person takes per minute.
Respiratory Rate
What part of the brain is responsible for coordinating movement, balance, and motor skills?
Cerebellum
Why is it important to only change one variable in an experiment at a time?
To know which variable is causing the change.
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
What manner of spread is spread by the bite of an infected tick.
Vector borne
Which vital sign corresponds with the following definition: When the heart pumps, the arteries expand and contract as blood is pushed through.
Pulse
What lobe is responsible for smell, sound and language processing?
Temporal Lobe
Which part of the nervous system inputs sensory information?
Peripheral Nervous System
Based on the test results in Figure 1, what is the patient’s diagnosis?
The patient is negative for both influenza and strep throat.
What manner of spread is spread through breathing, coughing, and sneezing.
Person to Person
Which vital sign corresponds with the following definition: The force of the blood against the artery walls during contraction and relaxation of the heart.
Blood Pressure
What functions might be affected in a patient with a tumor in the frontal lobe?
Behavior and personality, such as planning, initiated movements, social and emotional processing, and attention.
Why is it difficult to identify the cause of many nervous system disorders?
The genes associated with the diseases are not fully known, there can be no obvious defects in brain structure, the onset and display of symptoms often varies between patients.
A patient comes to you with complaints of intense headaches on the left side of his head just behind his eye. He also tells you that lately he has had trouble concentrating and feels unusually angry and confused. You ordered a variety of diagnostic tests and have the following results:
Patient’s speech, hearing, and vision appear normal.
Patient’s ability to perform memory tasks is less than expected for his age.
Patient’s ability to control movement and balance appear normal.
Due to these symptoms, you suspect an issue with his central nervous system. What additional test or tests would you order to help with the diagnosis and why?
CT or MRI scan
Is the following the correct way to plate bacteria? YES OR NO
You should hold the petri dish upside down at a 45 degree angle above you and rub the bacteria back and forth in close parallel lines across the plate. You need to rotate it 90 degrees and repeat, then again 45 degrees and repeat. Finish off with one circular sweep around the edge of the dish. Don’t reinsert the swab into the snap cap tube.
Yes
A group of students performed an experiment to see whether running in place for two minutes or being in a hot room would increase body temperature.
They had five students sit in a chair for two minutes and then measured their body temperature.
They had the same five students run in place for two minutes in a hot room and then measured their body temperature after running.
They repeated the experiment three times.
They analyzed their results; they concluded that running in place does increase body temperature and that being in a hot room does increase body temperature.
What was wrong with Experiment 1?
They didn't include a control group
Which part of the brain is responsible for regulating basic life functions like breathing, heart rate, and blood pressure, as well as relaying information between the spinal cord and the rest of the brain?
Brain Stem
Lindsey is taking pictures of animals at a local park. She sees a squirrel run across the grass and up a nearby tree. Lindsey picks up her camera and takes a picture of the squirrel.
Explain how the nervous system worked to sense, process, and respond to stimuli in Lindsey’s scenario. In your explanation, include the input the peripheral nervous system receives and the output the central nervous system initiates.
Sensory neurons see the squirrel run, which send signals to her brain. The brain sends signals to her motor neurons to prompt her to pick up the camera.
