Hypocapnia will lead to which of the following conditions?

A.

Hypoventilation due to acidosis

B.

Hypoventilation due to alkalosis

C.

Hyperventilation due to acidosis

D.

Hyperventilation due to alkalosis

E.

Hypocapnia does not affect ventilation rate.

Answer and Explanation

The Correct Answer is D

A. Hypoventilation due to acidosis: Hypoventilation would increase CO₂, leading to respiratory acidosis, not hypocapnia.
B. Hypoventilation due to alkalosis: Hypocapnia is a result of hyperventilation, not hypoventilation.
C. Hyperventilation due to acidosis: Hyperventilation is a response to acidosis to blow off CO₂, but hypocapnia itself is a result of hyperventilation.
D. Hyperventilation due to alkalosis: Hypocapnia (low CO₂) leads to respiratory alkalosis. This occurs due to hyperventilation, which blows off too much CO₂.
E. Hypocapnia does not affect ventilation rate: CO₂ levels significantly influence ventilation via central chemoreceptors.

Correct Answer is A

Explanation

A. Liver: The liver is a large, reddish-brown organ in the right upper quadrant of the abdomen, just beneath the diaphragm. If the diagram is pointing to this area, especially the largest solid organ on the right side, it matches the liver’s location and size.

B. Stomach: The stomach is located mainly in the left upper quadrant, inferior to the diaphragm and to the left of the liver. It is smaller and has a J-shaped structure, so it would not match if the pointer is on the large right-sided organ.

C. Spleen: The spleen is located in the left upper quadrant, lateral to the stomach and posterior to the rib cage. It is much smaller than the liver and not in the right-sided position indicated.

D. Diaphragm: The diaphragm is a dome-shaped muscle that separates the thoracic and abdominal cavities. If the pointer is on the muscle just beneath the lungs, it would be the diaphragm, but here it’s on a large organ, not a muscle.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}

Explanation

A. Insulin; glucagon and epinephrine: Insulin promotes glycogenesis (storage of glucose as glycogen), while glucagon and epinephrine stimulate glycogenolysis (breakdown of glycogen to glucose).
B. Insulin; aldosterone: Aldosterone regulates sodium and potassium; not directly involved in glucose metabolism.
C. Growth hormone; glucagon and epinephrine: GH has minimal effect on glycogenesis. The second part is correct, but the first is not.
D. Growth hormone; cortisol: Cortisol can promote gluconeogenesis, not specifically glycogenolysis. GH does not drive glycogenesis.
E. Growth hormone; insulin: Insulin does not stimulate glycogenolysis. This pairing is incorrect.
