Question 1

Which type of brain wave activity indicates calm,positive feelings?

Accepted Answer

Alpha waves are associated with relaxed, positive feelings and are often observed during meditative and peaceful states. They are typically found in the range of 8-13 Hz and can indicate a person is feeling calm and relaxed. REM waves are associated with dreaming and sensory processing during sleep, Delta waves are typically found during deep sleep and unconsciousness, and Gamma waves are associated with high levels of concentration and focus.

Question 3

One of the problems encountered by psychiatrists who prescribe medication for patients with bipolar disorder is that patients often

Accepted Answer

Patients with bipolar disorder may stop taking medication in order to bring on a manic state, as they may feel that this state brings them a sense of euphoria or productivity. This is a known problem in medication adherence among bipolar patients, and it can lead to manic episodes that can be dangerous or disruptive to their lives. It is important for psychiatrists to work with patients to understand the importance of medication adherence and to address any concerns or fears that may be driving their decision to stop taking medication.

Question 4

Current research into neurotransmitter systems has produced the "permissive" hypothesis,which means that

Accepted Answer

The "permissive" hypothesis suggests that when serotonin levels are low, other neurotransmitter systems become dysregulated and contribute to mood irregularities. This means that it's not just low levels of serotonin alone that are responsible for mood disorders, but rather the overall dysregulation of neurotransmitter activity.

Question 6

Being depressed ________ the risk of death in elderly patients who have had a stroke or heart attack.

Question 7

Tamara gave birth to a healthy child four days ago.Now she is tearful and having mood swings.Fortunately,these symptoms disappeared relatively quickly.Tamara was probably suffering from

Accepted Answer

Tamara's symptoms of tearfulness and mood swings are characteristic of "baby blues," which is a common condition that affects up to 80% of new mothers in the first few weeks after giving birth. Baby blues usually fade away within a few days without treatment. Postpartum depression (choice A) is a more severe and long-lasting form of depression that can occur after childbirth and requires medical attention. Dysthymia (choice C) and cyclothymia (choice D) are chronic mood disorders that are not typically associated with childbirth.

Question 8

Accepted Answer

While many depressed patients also experience anxiety, not all anxious patients necessarily have depression.

Question 9

Cross-cultural research indicates that,due at least in part to appalling social and economic conditions,the prevalence of major depression is extremely high among

Accepted Answer

Cross-cultural research indicates that Native Americans have a higher prevalence of major depression compared to other ethnic groups in the United States. This may be attributed to factors such as historical trauma, discrimination, poverty, and loss of cultural identity.

Question 10

With regard to the prevalence of mood disorders,it has been consistently found that

Accepted Answer

Bipolar disorder can have an onset at any age, although it most commonly begins in adolescence or early adulthood. The other options are not accurate, as females actually experience major depressive disorder more frequently than males, and there is not a consistent pattern of men having more mood disorders than women. Dysthymia also has been found to occur slightly more frequently in women.

Question 11

Milton has been mildly depressed for many years.Just recently,however,his depression deepened,and he was severely depressed for about three months.His deep depression then lifted and he was once again mildly depressed.Milton

Accepted Answer

The fact that Milton has experienced mild depression for years and has had a recent episode of severe depression suggests that he may have a chronic or recurrent form of depression. This type of depression often requires a longer and more intense course of treatment to maintain a normal mood state. It does not necessarily mean that he will need treatment for the rest of his life, but ongoing treatment and monitoring may be necessary to prevent future episodes of severe depression.

Question 12

Question 15

Since traditional antidepressant medication such as tricyclics may actually provoke rapid cycling in patients with bipolar disorder,mood stabilizers and ________ are often prescribed instead.

Accepted Answer

Mood stabilizers and anticonvulsants are commonly prescribed for bipolar disorder as they help to regulate mood swings and prevent episodes of mania and depression. Antipsychotics may also be prescribed in certain cases, but tranquilizers and opiates are generally not recommended as they can exacerbate symptoms and lead to dependence.

Question 16

In about _____________ percent of patients,cyclothymic mood swings develop into full-blown bipolar disorder.

Accepted Answer

Cyclothymic mood swings develop into full-blown bipolar disorder in about 25 - 33 percent of patients.

Question 17

The presence of medical illnesses or symptoms of dementia can make the diagnosis of depression difficult in

Accepted Answer

The presence of medical illnesses or symptoms of dementia can complicate the diagnosis of depression, especially in the elderly population. This is because the symptoms of depression may overlap with those of medical conditions such as chronic pain or cognitive decline. Additionally, elderly individuals may not present with typical symptoms of depression, such as sadness or loss of interest, but instead may exhibit irritability, apathy, or social withdrawal. Therefore, it is important for healthcare providers to conduct a thorough evaluation of physical and cognitive functioning in older adults to accurately diagnose depression.

Question 18

Which of the following 8-year-old children should most likely receive a diagnosis of disruptive mood dysregulation disorder?

Accepted Answer

Disruptive mood dysregulation disorder (DMDD) is characterized by severe and recurrent temper outbursts that are grossly out of proportion in intensity or duration to the situation or provocation. These symptoms must occur three or more times a week for at least 12 months to meet the diagnostic criteria. Mary Ann's irritability and temper outbursts suggest DMDD, whereas the other options do not fit the diagnostic criteria.

Question 19

At various times,Cynthia,a 20-year-old college student,has always been considered by her family and/or friends to be moody,high-strung,explosive,or hyperactive.Knowing the criteria for mood disorders,you would diagnose Cynthia with

Accepted Answer

Based on the given information, Cynthia displays mood swings and high activity levels, which are consistent with the diagnostic criteria for cyclothymia. This disorder involves numerous episodes of hypomanic and depressive symptoms that do not qualify for a full manic or major depressive episode. Cynthia's symptoms of moody, high-strung behavior indicate that she has been experiencing mood swings, which are a key feature of cyclothymia. Additionally, the other disorders listed (major depressive disorder, panic disorder, and Disrupted mood dysregulation disorder) do not fully capture her symptoms as described.

Question 20

In research looking at the biological causes of mood disorders,studies have shown that if one of a set of twins is unipolar,the probability that the other twin is unipolar is ___________ percent.

Accepted Answer

The probability that the other twin is unipolar when one twin is unipolar is estimated at around 80%, indicating a strong genetic component to mood disorders. This supports the theory that biological causes play a significant role in the development of mood disorders.
