1. She checks the documentary requirements for the applicants for staff nurse position. Which

A. Certificate of previous employment
B. Record of related learning experience (RLE)
C. Membership to accredited professional organization
D. Professional identification card

Correct answer: C

Rationale: The correct answer is C: 'Membership to accredited professional organization.' When hiring staff nurses, verifying their membership to an accredited professional organization is crucial as it ensures that the applicant is recognized and affiliated with a reputable body in the nursing field. This membership signifies adherence to professional standards and ongoing education and development. While the other options are important in assessing a candidate's qualifications, membership to an accredited professional organization directly relates to the professional standing and commitment to the nursing profession, making it a key documentary requirement for the staff nurse position.

2. A rocket blasts off from Earth. What is the main force propelling the rocket upwards?

A. Gravitational force
B. Air resistance
C. Thrust from the rocket engine
D. Normal force from the launchpad

Correct answer: C

Rationale: Thrust from the rocket engine. This force is produced by the action-reaction principle and pushes the rocket upwards against the exhaust gases.

3. The largest level of ecological organization is a:

A. Population
B. Community
C. Ecosystem
D. Biome

Correct answer: D

Rationale: Rationale: A) Population: A population consists of individuals of the same species living in the same area. It is a smaller level of ecological organization compared to a biome. B) Community: A community consists of populations of different species living and interacting in the same area. It is a larger level of organization than a population but smaller than an ecosystem or biome. C) Ecosystem: An ecosystem includes all living organisms (biotic factors) and their physical environment (abiotic factors) interacting in a particular area. It is a larger level of organization than a community but smaller than a biome. D) Biome: A biome is the largest level of ecological organization and encompasses a large geographic area characterized by a specific climate, vegetation, and animal life. Biomes can be found on multiple continents and are defined by similar abiotic and biotic factors.

4. Identify the compound-complex sentence in the following options:

A. The baker decorated the cake, and then he presented it proudly.
B. Although it was raining, the children played outside.
C. When the sun rises, the birds begin to sing.
D. He enjoyed reading the book because it was suspenseful.

Correct answer: D

Rationale: A compound-complex sentence contains at least two independent clauses and at least one dependent clause.

5. The microscopic functional unit of the kidney responsible for filtering blood is the:

A. Ureter
B. Nephron
C. Renal pelvis
D. Bladder

Correct answer: B

Rationale: The correct answer is B: Nephron. The nephron is the microscopic functional unit of the kidney responsible for filtering blood and producing urine. It consists of the glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, and distal convoluted tubule. The other options, A: Ureter, C: Renal pelvis, and D: Bladder, are incorrect as they are not parts of the nephron but rather other structures involved in the urinary system. The ureter is a tube that carries urine from the kidneys to the bladder, the renal pelvis is a funnel-shaped structure in the kidney that collects urine, and the bladder stores urine before it is excreted from the body.

6. In a food chain, which trophic level captures energy from the sun?

A. Decomposers
B. Carnivores
C. Producers
D. Omnivores

Correct answer: C

Rationale: Rationale: Producers, such as plants, algae, and some bacteria, are the organisms in a food chain that capture energy from the sun through the process of photosynthesis. They convert sunlight into chemical energy, which is then passed on to other organisms in the food chain. Producers are at the base of the food chain and form the foundation for all other trophic levels to obtain energy. Decomposers (option A) break down organic matter, carnivores (option B) consume other animals, and omnivores (option D) consume both plants and animals, but they do not directly capture energy from the sun.
