Two people are waiting for their appointments at a neurology clinic. Dani has a seizure disorder and her neurologist wants to look at her overall pattern of brain activity to determine the location of the seizures. Paul’s physician suspects that he has a tumor and needs to get a clear picture of his brain’s anatomy.

What type of test is Dani’s physician most likely to order?
1. PET Scans
2. CT Scan
3. MRI
4. fMRI
5. EEG
What type of test would Paul’s physician order?
1. PET Scans
2. CT Scan
3. MRI
4. fMRI
5. EEG
What is the primary difference between Dani and Paul's types of tests?

Expert Solution

a. What type of test is Dani's physician most likely to order?

The correct answer is EEG

Justification - The Electroencephalogram (EEG) is a test which is used to see the alterations in the activity of the brain. EEG test plays a vital role to diagnose Seizure, Epilepsy, sleeping issues and many more.

b. What type of test would Paul's physician order?

The correct answer is fMRI.

Justification - The Functional Magnetic Resonance Imaging (fMRI) is a test which proves to be very useful in getting a crystal clear picture of the brain's anatomy as compare to other techniques. It is helpful in diagnosing deformity in the brain.

c. What is the primary difference between Dani and Paul's types of test?

In the Electroencephalogram (EEG) test electrodes of EEG are used to see the brain's electrical activity. The Neuron network present in the brain does the transmission through the electrical and chemical waves. The wave are used by the amplifier of the EEG in order to measure the activity of the brain.

In the Functional Magnetic Resonance Imaging (fMRI), the protons from the Hydrogen in our body is used to develop an image of the brain, as it generates energy. During the fMRI, when we see the patient's brain activity. There is a blood flow happening in the parts of the brain, from one end to another when there happens a brain activity. Hence, the clear picture of the brain is taken.

Four patients have made appointments to have their blood pressure checked at a clinic. As each patient is selected, he/she is tested. If he/she has high blood pressure, a success (S) occurs; if he/she does not have high blood pressure, a failure (F) occurs. Let x be the number of persons who have high blood pressure (i.e., Let x represent the number of successes among the four sampled persons). How many outcomes should you have from this probability experiment?...

D.V., a 32-year-old man, is being admitted to the medical floor from the neurology clinic for evaluation of his symptoms. D.V. has experienced increasing urinary frequency and urgency over the past 2 months. Because his female partner was treated for a sexually transmitted infection, D.V. underwent treatment, but the symptoms did not resolve. D.V. has also recently had two brief episodes of eye “fuzziness” associated with diplopia and flashes of brightness. He has noticed ascending numbness and weakness of the...

A doctor has scheduled two appointments, one at 1pm and the other at 1:30pm. The amount of time the doctor spends with the patient is a constant 20 minutes plus a random amount of time which is distributed as exponential with mean 8 minutes. Assume that both patients will be on time for their appointments. What is the chance the doctor will be late for her 1:30 appointment because she spends more than 30 minutes with her 1pm appointment? On...

The student nurse prepares the medication under the supervision of the instructor and takes the medication to the bedside. The student further completes the Nine Rights by computer-checking the bar code on the patient’s wrist band. The patient refuses the medication, saying, “I have already had my medication this morning. You are...
