1. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

A. Possesses inspirational quality that makes followers gets attracted of him and regards
B. Acts as he does because he expects that his behavior will yield positive results
C. Uses visioning as the core of his leadership
D. Matches his leadership style to the situation at hand.

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

2. Where does cellular respiration, the process of converting chemical energy into ATP, take place in eukaryotic cells?

A. Nucleus
B. Ribosomes
C. Mitochondria
D. Golgi apparatus

Correct answer: C

Rationale: Rationale: Cellular respiration, the process of converting chemical energy into ATP, takes place in the mitochondria of eukaryotic cells. The mitochondria are known as the powerhouse of the cell because they are responsible for generating most of the cell's ATP through the process of cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the primary energy currency of the cell. The other organelles listed in the options (nucleus, ribosomes, and Golgi apparatus) do not play a direct role in cellular respiration.

3. The primary source of energy entering most ecosystems is:

A. Chemical energy stored in bonds
B. Thermal energy from the Earth's core
C. Light energy from the sun
D. Kinetic energy from wind and water

Correct answer: C

Rationale: Rationale: In most ecosystems, the primary source of energy is sunlight. This energy is captured by plants and other photosynthetic organisms through the process of photosynthesis. These organisms convert light energy into chemical energy stored in the bonds of organic molecules, such as glucose. This stored chemical energy is then passed on to other organisms in the ecosystem through the food chain, making sunlight the fundamental source of energy for most ecosystems. Thermal energy from the Earth's core (option B) is not a primary source of energy for ecosystems, as it is not readily accessible to most organisms. Kinetic energy from wind and water (option D) can play a role in some ecosystems, but it is not the primary source of energy. Chemical energy stored in bonds (option A) is a form of energy that is derived ultimately from the sun through photosynthesis.

4. The major site for nutrient absorption in the digestive system is the:

A. Mouth
B. Stomach
C. Small intestine
D. Large intestine

Correct answer: C

Rationale: The correct answer is C: Small intestine. The small intestine is the major site for nutrient absorption in the digestive system. It is where most of the digestion and absorption of nutrients from food takes place. The small intestine has villi and microvilli that increase its surface area, allowing for efficient absorption of nutrients like sugars, amino acids, and fatty acids into the bloodstream. The mouth is primarily responsible for mechanical digestion through chewing, while the stomach's main function is to break down food with enzymes and acids. The large intestine mainly absorbs water and electrolytes, with minimal nutrient absorption.

5. Which functional group is commonly found in ketones?

A. Hydroxyl
B. Carbonyl
C. Ester
D. Amine

Correct answer: B

Rationale: Ketones have the functional group -CO-, which is a carbonyl group. The other choices are associated with different functional groups

6. Which hormone, produced by the adrenal glands, helps regulate the body's response to stress, including increasing blood pressure and suppressing the immune system?

A. Aldosterone
B. Epinephrine
C. Cortisol
D. Insulin

Correct answer: c

Rationale: The correct answer is C: Cortisol. Cortisol is a hormone produced by the adrenal glands that plays a crucial role in the body's response to stress. It helps regulate blood pressure by increasing it to prepare the body for stressors. Additionally, cortisol suppresses the immune system to prioritize the stress response. Aldosterone, while also produced by the adrenal glands, primarily regulates electrolyte balance and blood pressure. Epinephrine, produced by the adrenal medulla, is involved in the fight-or-flight response but does not suppress the immune system like cortisol. Insulin, produced by the pancreas, regulates blood sugar levels and is not directly involved in the stress response. Therefore, Cortisol is the hormone that specifically helps regulate the body's response to stress by increasing blood pressure and suppressing the immune system.
