1. How does the nervous system work with the muscular system?

A. The muscles of the body produce chemicals that feed the nerves.
B. The nervous system tells the muscles how to respond to the environment.
C. The nervous system releases chemicals that remove excess waste from the muscles.
D. The muscular system provides input that allows the nerves to make decisions.

Correct answer: B

Rationale: The correct answer is B because the nervous system communicates with the muscular system to control voluntary and involuntary muscle movements. The nervous system sends signals to the muscles, instructing them on how to respond to various stimuli in the environment. This communication allows for coordinated movement and responses to external and internal changes. Choice A is incorrect because muscles do not produce chemicals to feed the nerves. Choice C is incorrect because the nervous system does not release chemicals to remove waste from the muscles. Choice D is incorrect because the muscular system does not provide input for the nerves to make decisions.

2. What is the correct verb to complete the sentence? 'Economics ___ my least favorite subject at school.'

A. Is
B. Been
C. Am
D. Are

Correct answer: A

Rationale: The correct answer is A: 'Is.' In this sentence, 'Economics' is being treated as a singular subject, so the verb should also be singular. 'Is' is the correct singular form of the verb to agree with the singular subject 'Economics.' Choice B, 'Been,' is incorrect because it is the past participle form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice C, 'Am,' is incorrect because it is the first-person singular form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice D, 'Are,' is incorrect because it is the plural form of the verb 'be' and does not agree with the singular subject 'Economics.'

3. What is the meaning of exocytosis?

A. The cell engulfs and brings in substances.
B. The cell releases content outside by fusing with the plasma membrane.
C. The cell engulfs liquid material.
D. The cell brings in solid particles.

Correct answer: B

Rationale: Exocytosis is the process by which a cell releases substances to the outside by fusing with the plasma membrane. During exocytosis, vesicles containing molecules fuse with the cell membrane, allowing the release of the contents outside the cell. This process is crucial for the secretion of various substances such as hormones, enzymes, and neurotransmitters. Choices A, C, and D are incorrect as they describe processes different from exocytosis. Choice A describes endocytosis, where the cell engulfs substances to bring them into the cell. Choice C is more aligned with pinocytosis, the process of engulfing liquid material. Choice D refers to phagocytosis, which is the uptake of solid particles by the cell.

4. Among many Asians there is a belief in the yin\yang theory, rooted in the ancient Chinese philosophy of Tao. The nurse recognizes which statement that most accurately reflects "health" in an Asian with this belief?

A. A person is able to work and produce.
B. A person is happy, stable, and feels good.
C. All aspects of the person are in perfect balance.
D. A person is able to care for others and function socially. - C) All aspects of the person are in perfect balance. Page: 21 Many Asians believe in the yin\yang theory, in which health is believed to exist when all aspects of the person are in perfect balance. The other statements do not describe this theory.

Correct answer: C

Rationale: In Asian belief systems like the yin\yang theory rooted in Tao philosophy, health is seen as existing when all aspects of a person are in perfect balance. This means that physical, mental, emotional, and spiritual elements need to be harmonized for an individual to be considered healthy. The other statements do not encapsulate this holistic perspective on health.

5. What type of cell is an animal cell?

A. Prokaryotic
B. Eukaryotic
C. Plant Cell
D. Bacterial Cell

Correct answer: B

Rationale: The correct answer is B, eukaryotic. Animal cells are classified as eukaryotic cells because they contain membrane-bound organelles such as the nucleus, mitochondria, and endoplasmic reticulum. Choice A, prokaryotic, is incorrect as prokaryotic cells lack membrane-bound organelles. Choice C, Plant Cell, is incorrect as the question specifically asks about animal cells. Choice D, Bacterial Cell, is incorrect as bacteria are prokaryotic cells.
