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.

A registered nurse (RN) is supervising the work of a licensed practical nurse (LPN) who is caring for a client diagnosed with a terminal illness. Which statement by the LPN would be corrected by the RN?

Answers

Answer: B. The law says you must write a new living will each time you re admitted to the hospital.

Explanation:

The law does not require that you make a new will whenever you are admitted to the hospital. Any existing will that has fulfilled the provisions of the law are biding unless the person decides to change the will of their own volition.

There is therefore no need to make a new will every time if there is already one in existence and the person is satisfied with it. The Registered Nurse should therefore correct this statement by the Licensed Practical Nurse.

A 19-year-old college sophomore comes to the emergency room because he has noticed a sudden onset of severe shortness of breath. It occurred while he was playing basketball. He is normally healthy and is a nonsmoker. He is an alert, thin, tall male in moderate discomfort secondary to respiratory distress. On physical examination of the lungs, the following is noted: hyperresonant to percussion over the left lung field; decreased to absent breath sounds on the left side and no adventitious sounds; decreased tactile fremitus on the left side. Based on the history and physical examination findings, what is the most likely diagnosis?

Answers

Answer:

Collapsed Lung (Pneumothorax)

Explanation:

"A pneumothorax is a collection of free air in the chest outside the lung that causes the lung to collapse.

[...]In some instances, the lung continues to leak air into the chest cavity and results in compression of the chest structures, including vessels that return blood to the heart. This is referred to as a tension pneumothorax and can be fatal if not treated immediately.

Examination of the chest with a stethoscope reveals decreased or absent breath sounds over the affected lung. The diagnosis is confirmed by chest X-ray."

The antidepressant fluoxetine (or Prozac) has a half-life of about days. What percentage of a dose remains in the body after one day?

Answers

The complete question is :

The antidepressant fluoxetine (or Prozac) has a half-life of about 3 days. What

percentage of a dose remains in the body after one day

Answer: 79.4 per cent.

Explanation:

Half life of a substance can be defined as the amount of time taken to degrade it half or it can be defined as the time which is required by the substance to become half of its original amount.

Here we need to find the half life of a medicine fluoxetine.

The equation which can be written for the question is :P(t) which will provide the information about the amount of medicine left in the body after one day or time (t)

Since the half-life is 3 days, P(t) = 2−t/3.

Then P(1) = 2−1/3 ≈ 0.794 =  0.794*100=79.4%  is the amount of substance left in the body after one day.
