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
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 D
Explanation
A. Obesity does not selectively affect only certain types of surgical procedures; rather, it generally increases the risk of complications across a wide range of surgical interventions. This includes both elective and emergency surgeries.
B. Obesity significantly impacts surgical risk. It is associated with a higher likelihood of complications such as wound infections, delayed wound healing, respiratory problems, and cardiovascular issues. The presence of excess body fat affects multiple physiological systems and can complicate both the surgical procedure and recovery.
C. Obesity does not decrease the risk of surgical complications; rather, it increases it. The excess body fat associated with obesity can lead to problems such as impaired wound healing, increased risk of infection, cardiovascular strain, and respiratory issues, which all contribute to a higher risk of complications during and after surgery.
D. This statement accurately reflects the relationship between obesity and surgical risk. Obesity is associated with an increased risk of a variety of surgical complications.
