Question 6

The bicarbonate buffer system (H2CO3/HCO3-) is the most important extracellular buffer in the human body. Its primary role is to maintain the physiological pH of blood within a narrow range. Which of the following statements accurately describes its function?

Accepted Answer

B. It quickly neutralizes excess H+ ions by forming carbonic acid, which can then be converted to CO2 and excreted by the lungs. — The bicarbonate buffer system acts rapidly to buffer pH changes in the extracellular fluid. When excess H+ ions are present, bicarbonate (HCO3-) combines with them to form carbonic acid (H2CO3). Carbonic acid then dissociates into CO2 and water, allowing CO2 to be expelled by the lungs, effectively removing acid from the body.

Answer

A. It primarily buffers intracellular pH changes.

Answer

C. It actively transports H+ ions out of the body via the kidneys.

Answer

D. It directly consumes CO2 to produce bicarbonate ions.

Question 8

In a classroom setting, a teacher notices that a student, despite being academically capable, often appears withdrawn, avoids group activities, and expresses feelings of loneliness. According to Maslow's hierarchy, which educational intervention should the teacher prioritize to support this student's learning and well-being?

Accepted Answer

C. Facilitating opportunities for positive social interaction and a sense of belonging. — The student's symptoms (withdrawn, avoiding groups, loneliness) point to unmet belongingness and love needs in Maslow's hierarchy. Addressing these social-emotional needs by fostering positive interactions and a sense of inclusion is crucial before higher-level needs like self-esteem or self-actualization can be effectively pursued. Options A, B, and D address higher (esteem) or lower (physiological, safety) needs, which are not the primary concern indicated by the student's specific behaviors.

Answer

A. Providing advanced academic challenges to boost self-esteem.

Answer

B. Ensuring the student has adequate food and a comfortable learning environment.

Answer

D. Setting clear rules and a predictable classroom routine to enhance safety.
