Mathematics

1. A child's toy block is a cube with side lengths of 5cm. What is its total surface area?

Correct answer: D

Rationale: Use the formula for surface area of a cube: 6 * (side length)^2 = 6 * (5cm)^2 = 125 sq cm.

2. What is the oxidation state of carbon in CH4?

Correct answer: d

Rationale: Each hydrogen atom has an oxidation state of +1, and the sum of oxidation states in CH4 is 0. Therefore, carbon has an oxidation state of -4.

3. Which hormone is responsible for the characteristic changes experienced during puberty, such as breast development and menstruation in females?

Correct answer: C

Rationale: The correct answer is C: Estrogen. Estrogen plays a crucial role in regulating the development of secondary sexual characteristics during puberty in females. It is responsible for breast development, widening of hips, and the onset of menstruation. Estrogen is mainly produced by the ovaries and is essential for the maturation of the reproductive system. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are pituitary hormones that regulate the menstrual cycle and ovulation but do not directly cause the characteristic changes seen during puberty. Progesterone is another hormone involved in the menstrual cycle and pregnancy but is not primarily responsible for the physical changes during puberty.

4. Which of the following is NOT a good scientific practice?

Correct answer: B

Rationale: Scientific objectivity requires considering all data, regardless of whether it aligns with initial expectations. Selective bias can lead to inaccurate conclusions.

5. One staff suggests that they review the pattern of nursing care that they are using, which is

When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.

6. The energy absorbed during a chemical reaction is called:

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.
