Anatomy

1. What is the feedback mechanism in the endocrine system that helps maintain hormone balance?

Correct answer: B

Rationale: The correct answer is B: Negative feedback, where a hormone suppresses its own release. In the endocrine system, negative feedback is a crucial mechanism that helps maintain hormone balance. When hormone levels rise, they signal the body to decrease further hormone production, preventing an excess. This ensures that hormone levels stay within a narrow range, promoting stability and homeostasis. Positive feedback (option A) would lead to an amplification of hormone release, which is not ideal for maintaining balance. Cascade effect (option C) involves a sequential activation of hormones but does not directly regulate hormone levels. Dual hormone system (option D) refers to two hormones working together but doesn't specifically address the feedback mechanism for maintaining hormone balance.

2. Which element is present in household bleach and has disinfectant properties?

Correct answer: B

Rationale: Chlorine's oxidizing ability makes it effective in killing bacteria and other microorganisms.

3. One leadership theory states that “leaders are born and not made,” which refers to which of the

Correct answer: A

Rationale: The correct answer is A: Trait. The statement 'leaders are born and not made' aligns with the Trait theory of leadership, which suggests that certain individuals are born with innate qualities and characteristics that make them effective leaders. This theory focuses on identifying specific traits, such as intelligence, charisma, and self-confidence, that are believed to be inherent in successful leaders. Charismatic leadership (option B) emphasizes the charm and appeal of a leader, Great Man theory (option C) suggests that leaders are born with unique qualities that set them apart, and Situational leadership (option D) focuses on adapting leadership style based on the situation. However, the statement in the question best corresponds to the Trait theory, making option A the correct choice.

4. When Harry uses team nursing as a care delivery system, he and his team need to assess the

Correct answer: C

Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.

5. What is the main function of the large intestine?

Correct answer: B

Rationale: The correct answer is B: "Absorb water." The main function of the large intestine is to absorb water and electrolytes from the undigested food material that passes through it. This helps in the formation of solid waste or feces, which is then stored in the rectum until it is eliminated from the body. Breaking down food primarily occurs in the small intestine, while the large intestine focuses on reabsorbing water to prevent dehydration. Secreting digestive enzymes is mainly done by the pancreas and liver, not the large intestine.

6. Hematopoietic tissue is responsible for

Correct answer: C

Rationale: Hematopoietic tissue is responsible for the production of blood cells. This specialized tissue is found in the bone marrow and is crucial for the continuous generation of red blood cells, white blood cells, and platelets. These blood cells play essential roles in oxygen transport, immune defense, and blood clotting. Building and repairing bone (option A) is primarily the function of osteoblasts and osteoclasts in bone tissue. Supporting and connecting tissues (option B) is the role of connective tissues like tendons and ligaments. Contracting for movement (option D) is the function of muscle tissue. Therefore, the correct answer is C, as hematopoietic tissue specifically focuses on blood cell production.
