Which neurotransmitter prepares the body for "fight or flight" and is seen in increased levels in patients with anxiety-related disorders?a. dopamine
b. serotonin
c. epinephrine
d. norepinephrine

Answers

Answer 1

Answer:

Answer:

c. epinephrine also known as Adrenaline

Explanation:

to better deals with challenges, epinephrine (adrenaline) and usually in combination with norepinephrine (noradrenaline) into the bloodstream. The so called "stress hormone" causes important changes in the body, represented by an increase in heart rate with high blood pressure.

We known it as "Fly or fight" response,as the heart rate and blood pressure increase, muscles gather more energy have more contractions.´

Glucose levels in muscles go higher, blood vessels get narrower, providing more energy for the muscles. Usually the eyes pupiles notice everything around, as adrenilne leves make you aware of the environment.

Anxiety related patients will have this too often, even in todays stressed world where sitations no longer require physical responses, the deep automated response is generated as the self perception of danger and fear interprets how to deal to possible threats.

A patients pulse oximetry reading is 92%. What is the bestmethod of oxygen administration for this patient?

Answers

Answer:

A low flow oxygen supply

Explanation:

92% is the threshold for hypoxia, meaning that below 92% a person may need Oxygen supply. Depending of each patient's level of saturation, there are different types of devices and pressures, the lower the Oxygen concentration the more the pressure needed, for 92% a patient may require a low pressure system, such as nasal cannula for supply from 24 to 40% of Oxygen concentration. The second option is a face mask, which provides between 28% and 50%.

Assume that an initial dose of 100 mg will produce a particular drug effect. After tolerance, which dose level would most likely produce an equivalent response?

Answers

Answer:

Tolerance means that due to repititve use of the drug, initial dose is unable to prpduce the same effect beacuse the receptors has been desensitized.

If An initial dose is 100 mg then dose higher than this which may be 2 or 3 times more potent may reverse this tolerance of the drug and it may then produce similar effects at a higher dose.

Explanation:

Tolerance is said to be the decreased response by the drug because of the continuous exposure to the drug at the receptor molecules. Due to this contionuous exposure the receptors become desensitized.

Tolerance occurs when the person no longer responds to the drug in the way that person initially responded. Tolerance can be reversed by increasing the dose of the drug lets say initial dose was 100 mg. To reverse the tolerance, a dose of 500 mg may be required or even more.

to control occasional pain and inflammation, a person uses an over-the-counter drug containing ibuprofen. interestingly, recent research shows that the person also may be reducing the risk of contracting which disease?

Answers

Recent research has shown that using over-the-counter drugs containing ibuprofen can potentially reduce the risk of developing certain types of cancer.

Specifically, studies have suggested that regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen may lower the risk of developing colon, breast, and prostate cancers. This is because NSAIDs work by blocking an enzyme called cyclooxygenase (COX), which is involved in inflammation and also plays a role in the development of certain cancers.

By inhibiting COX, NSAIDs may help prevent the growth and spread of cancer cells. However, it is important to note that regular use of NSAIDs can also have side effects and risks, such as gastrointestinal bleeding and kidney damage.

Therefore, it is important for individuals to consult with their healthcare provider before using NSAIDs for long periods of time or on a regular basis. Therefore ibuprofen can reduce the risk of the disease cancer.
