The Correct Answer is B
During exercise, the heart has to work harder to pump blood and oxygen to the muscles. In patients with stable angina, there is a partial blockage of the coronary arteries, which reduces blood flow and oxygen delivery to the heart muscle. This lack of oxygen to the heart muscles causes chest pain or discomfort, which subsides when the patient stops exercising and is relaxed.
Therefore, it is important for the patient with stable angina to avoid activities that trigger chest pain, take prescribed medications, and make lifestyle modifications to manage their condition.

Correct Answer is A
Explanation
A. Respiratory acidosis.
COPD is a chronic lung disease that can lead to an accumulation of carbon dioxide (CO2) in the body. This can cause respiratory acidosis, a condition in which the blood pH is lower than normal due to an excess of CO2.
In respiratory acidosis, the partial pressure of carbon dioxide (PaCO2) in the blood is increased and the pH is decreased. The kidneys atempt to compensate for the acidosis by excreting more acid in the urine and retaining more bicarbonate, but this compensation is usually not enough to fully correct the problem.
Metabolic alkalosis (option B) is a condition in which the blood pH is higher than normal due to an excess of bicarbonate in the blood. This is usually caused by loss of acid from the body, such as through vomiting or use of diuretics.
Respiratory alkalosis (option C) is a condition in which the blood pH is higher than normal due to a decrease in PaCO2. This can be caused by hyperventilation, which leads to excessive elimination of CO2 from the lungs.
Metabolic acidosis (option D) is a condition in which the blood pH is lower than normal due to an excess of acid in the blood. This can be caused by a variety of factors, including kidney failure or lactic acidosis.
Correct Answer is A
Explanation
Deep breathing or "diaphragmatic breathing" is a technique used to prevent recurrent pneumonia and improve lung function. During deep breathing, the patient is instructed to inhale deeply, expanding their lung volume as much as possible. This process is called inspiration.
Expiration, on the other hand, is the process of exhaling or breathing out air from the lungs. Intake refers to the process of taking in air or breathing in, while chest is a part of the body where the lungs are located.
