Biology

1. Which of the following is the main function of the small intestine?

Correct answer: B

Rationale: Rationale: The small intestine is a crucial part of the digestive system where the majority of nutrient absorption takes place. It is lined with tiny finger-like projections called villi that increase the surface area for absorption. The small intestine absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals from the digested food into the bloodstream to be transported to cells throughout the body for energy, growth, and repair. Options A, C, and D do not accurately describe the main function of the small intestine.

2. Which hormone, produced by the ovaries, is responsible for the development of the uterine lining during the menstrual cycle and supports early pregnancy?

Correct answer: B

Rationale: The correct answer is B: Progesterone. Progesterone is a hormone produced by the ovaries that plays a crucial role in the menstrual cycle and early pregnancy. During the menstrual cycle, progesterone helps to prepare the uterine lining for a potential pregnancy by making it thick and vascularized. If fertilization occurs, progesterone continues to support the early stages of pregnancy by maintaining the uterine lining and preventing menstruation. Estrogen also plays a role in the menstrual cycle by stimulating the growth of the uterine lining, but progesterone is primarily responsible for maintaining the uterine environment suitable for implantation and supporting early pregnancy. Testosterone is a male sex hormone, while prolactin is a hormone involved in milk production after childbirth.

3. What type of bond involves the complete transfer of electrons between atoms?

Correct answer: B

Rationale: Ionic bond - Electrons are completely transferred from one atom to another, creating cations and anions with strong electrostatic attraction.

4. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

5. He raised the issue on giving priority to patient needs. Which of the following offers the best

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.

6. What is the main function of vacuoles in plant cells?

Correct answer: D

Rationale: Rationale: Vacuoles in plant cells primarily function as storage organelles. They store water, enzymes, pigments, and waste products. Vacuoles help maintain turgor pressure within the cell, which provides structural support for the plant cell. While vacuoles can also be involved in transporting substances within the cell, their main function is storage. Synthesizing proteins and lipids is primarily carried out by other organelles such as the endoplasmic reticulum and Golgi apparatus.
