MD Course Final - Review

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.
• The patient has strep throat and not influenza.

A person is running a race. Which of the following will happen to their vital signs as they’re running?

• Pulse, blood pressure, and respiration rate will increase.
• Pulse, blood pressure, and respiration rate will stay the same.
• Pulse, blood pressure, and respiration rate will decrease.
• There's no way to know.

What functions might be affected in a patient with a tumor in the occipital lobe?

• Behavior and personality, such as planning, initiated movements, social and emotional processing, and attention.
• Sensing touch, spatial processing, language, and memory.
• Visual perception and some forms of visual short-term memory.
• Processing smell and sound, and the ability to recognize and understand words and language.

Several students came to the office with stomach aches and vomiting a few hours after a pancake breakfast. A foodborne illness was suspected for the outbreak, and students were interviewed about the food they ate earlier that day. Given the attack rates shown in Table 1, which food item is the most likely source of the illness that’s causing several students to get sick?

• Sausage
• Butter
• Milk
• Juice

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
• Motor neurons
• Brain
• Spinal cord

Which label identifies a part of the central nervous system?

• A
• B
• C
• D

Many cases of patients with similar symptoms are being admitted to a local emergency room. It is believed that these patients are sick from a foodborne illness outbreak caused by a bacterial disease agent that leads to problems with the nervous system. 

How would medical professionals work to help these patients and prevent future cases? Choose ALL that apply

• The ER doctor would work with a neurologist to diagnose and treat the patient.

• A microbiologist would work with the patient sample sent to the lab to confirm the presence of the bacteria or determine the best antibiotic to use.

• An epidemiologist would investigate patterns between the affected patients and investigate causes of the illness to identify the source of the outbreak and prevent further illness.

• None of these

Experiment 1

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.

Which of the following should be included in a clear protocol for Experiment 1? Choose ALL that apply

• Includes a control.

• Each step is clear and specific so another scientist could repeat your experiment.

• Includes multiple trials.

• Includes multiple independent variables

Match the cause of illness to the standard treatment.

• Antibiotic medication

• virus

• Rest, fluids, occasionally antiviral med

• fungus

• Antifungal medication

• bacteria

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 scan because it can show brain abnormalities

• BLC scan because it can show blood abnormalities

• MRI scan because it can show brain abnormalities

• NRV scan because it can show nerve abnormalities
