Which of the following describes the effect of air entering the pleural space?
Increases the vital capacity
Increases the residual capacity
Compresses the chest wall, causing the lung on the affected side to collapse
Compresses the lung, causing the lung on the affected side to collapse
The Correct Answer is D
A. Air entering the pleural space (such as in a pneumothorax) does not increase the vital capacity; rather, it reduces lung expansion and can decrease lung volumes.
B. Air in the pleural space does not increase the residual capacity. It may interfere with the normal functioning of the lungs and reduce the effective air exchange.
C. The pleural space is between the lung and the chest wall. When air enters this space (pneumothorax), it causes the lung on the affected side to collapse due to loss of the negative pressure that holds the lung expanded. It does not compress the chest wall.
D. When air enters the pleural space, it causes the lung on the affected side to collapse, as the air disrupts the negative pressure in the pleural cavity that keeps the lungs inflated. This results in a condition known as pneumothorax.

Correct Answer is B
Explanation
A. Excessive aldosterone causes increased reabsorption of sodium and water, and the excretion of potassium. Therefore, excessive aldosterone would typically decrease plasma potassium levels, not increase them.
B. Aldosterone stimulates the kidneys to reabsorb sodium and excrete potassium, leading to increased plasma sodium levels. This is the correct effect of excessive aldosterone secretion.
C. Phosphorus levels are not directly affected by aldosterone; its primary role is in regulating sodium and potassium balance.
D. Aldosterone does not directly regulate calcium levels in the blood, so plasma calcium levels are not significantly affected by aldosterone secretion.
Correct Answer is D
Explanation
A. Flexion refers to a bending movement that decreases the angle between two body parts, such as bending the knee or elbow, but it does not involve lateral movement away from the body's midline.
B. Adduction is the movement of a body part toward the midline of the body, opposite of what the question describes.
C. Extension refers to a straightening movement that increases the angle between two body parts, such as straightening the arm or leg, but again does not involve lateral movement.
D. Abduction is the correct term for moving a limb or body part away from the midline of the body. In this case, it refers to the lateral movement of the leg away from the body's midline.
