A nurse is teaching a class about oxygen transport in the cardiopulmonary system. Which of the following transports oxygen in the blood?

Lymphocytes

Neutrophils

Platelets

Hemoglobin

Answer and Explanation

The Correct Answer is D

A.   Lymphocytes are a type of white blood cell that plays a crucial role in the immune system, specifically in the response to infections and in immune regulation. They do not have a role in the transport of oxygen in the blood.
B.   Neutrophils are another type of white blood cell that is essential for fighting bacterial infections. They are part of the body's immune response but do not transport oxygen.
C.   Platelets are small cell fragments that are crucial for blood clotting and wound repair. They do not have a role in oxygen transport.
D.   Hemoglobin is the primary molecule responsible for transporting oxygen in the blood. It is a protein found in red blood cells (erythrocytes) that binds to oxygen in the lungs and releases it in tissues throughout the body. Hemoglobin carries the majority of oxygen in the bloodstream and is essential for effective oxygen transport and delivery.

Correct Answer is B

Explanation

A. Abdominal pain is not a direct manifestation of respiratory acidosis. However, it may be associated with other conditions or complications but is not a primary indicator of respiratory acidosis.
B. Lethargy or drowsiness is a common symptom of respiratory acidosis. The increased CO₂ levels lead to an acidic environment that can affect brain function, resulting in decreased alertness, confusion, or drowsiness.
C. Numbness or tingling of the fingers is more commonly associated with respiratory alkalosis, which is characterized by a decreased level of CO₂ and increased blood pH. This condition can cause peripheral numbness and tingling due to altered blood pH affecting nerve function.
D. Dry skin is not a direct manifestation of respiratory acidosis. While it might be a sign of dehydration or other systemic issues, it is not specifically linked to respiratory acidosis.
