1. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. What is the muscular sac in the female body that nourishes and protects a developing fetus?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus is a muscular sac in the female body where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment to the developing fetus and protects it throughout gestation. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the canal leading from the uterus to the outside of the body. Therefore, the uterus is the specific organ responsible for nourishing and protecting a developing fetus in the female body.

3. What is the process of cells dividing to produce new cells called?

• A. Cell division
• B. Cell differentiation
• C. Cell growth
• D. Cell regeneration

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

4. What is the primary function of the coronary arteries in the cardiovascular system?

• A. Carry oxygenated blood to the heart muscle
• B. Carry deoxygenated blood from the heart muscle
• C. Pump blood to the lungs for oxygenation
• D. Regulate blood pressure in the systemic circulation

Correct answer: A

Rationale: The primary function of the coronary arteries in the cardiovascular system is to carry oxygenated blood to the heart muscle. These arteries supply the heart muscle with the necessary oxygen and nutrients it needs to function properly. Without adequate blood flow through the coronary arteries, the heart muscle can become deprived of oxygen, leading to conditions like angina or even a heart attack. Options B, C, and D are incorrect as they do not accurately describe the function of the coronary arteries. Option B is incorrect because the coronary arteries carry oxygenated blood, not deoxygenated blood. Option C is incorrect because the pulmonary arteries, not the coronary arteries, carry blood to the lungs for oxygenation. Option D is incorrect because the regulation of blood pressure in the systemic circulation is primarily controlled by mechanisms such as the kidneys and the autonomic nervous system, not the coronary arteries.

5. Which part of the brain is responsible for coordinating muscle movements, maintaining balance, and posture?

• A. Cerebrum
• B. Cerebellum
• C. Medulla oblongata
• D. Thalamus

Correct answer: b

Rationale: The correct answer is B: Cerebellum. The cerebellum is responsible for coordinating muscle movements, maintaining balance, and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate voluntary movements. The cerebrum, on the other hand, is mainly responsible for higher brain functions such as thinking and problem-solving. The medulla oblongata controls autonomic functions like breathing and heart rate, while the thalamus acts as a relay station for sensory information. Therefore, the cerebellum is the specific part of the brain that plays a crucial role in motor coordination and balance.

6. Ms. Valencia prepares the process standards. Which of the following is NOT a process

• A. Initial assessment shall be done to all patients within twenty four hours upon admission.
• B. Informed consent shall be secured prior to any invasive procedure
• C. Patients’ reports 95% satisfaction rate prior to discharge from the hospital.
• D. Patient education about their illness and treatment shall be provided for all patients and their

Correct answer: D

Rationale: In this question, Ms. Valencia is tasked with preparing process standards, which are systematic procedures or steps followed to ensure quality care. Options A, B, and C all refer to specific processes that are essential in healthcare: timely assessment, obtaining informed consent, and assessing patient satisfaction. However, option D about providing patient education is more focused on an outcome (patient education) rather than a specific process standard. While patient education is important, the question is asking for a process standard, making option D the correct answer as it does not directly relate to a specific process standard.
