Nursing Elites

1. Neurons, the functional units of the nervous system, belong to which tissue type?

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: D

Rationale: Neurons are the functional units of the nervous system and are specialized cells that transmit nerve impulses. They belong to nervous tissue, which is the primary tissue type of the nervous system. Nervous tissue is composed of neurons and supporting cells called neuroglia. Choices A, B, and C are incorrect because epithelial tissue functions mainly in covering and lining body surfaces, connective tissue provides support and structure, and muscle tissue is responsible for movement. Neurons, being the basic functional units of the nervous system, are specifically classified under nervous tissue.

2. The teacher shared several apothegms with the class, hoping that the short, wise sayings would inspire thoughtful discussions.

• A. instructions
• B. questions
• C. sayings
• D. lectures

Correct answer: C

Rationale: In this context, apothegms refers to short, wise sayings meant to convey wisdom or provoke thought. Apothegms are concise and insightful, serving as nuggets of wisdom. The term 'instructions' implies a set of directions or guidelines, not reflective of the nature of apothegms. 'Questions' are queries seeking information or answers, not synonymous with wise sayings. 'Lectures' are formal presentations or speeches, which are more extensive and detailed compared to the concise nature of apothegms.

3. What type of joint connects the bones of the skull?

• A. Hinge joint
• B. Fibrous joint
• C. Ball-and-socket joint
• D. Pivot joint

Correct answer: B

Rationale: The correct answer is B: Fibrous joint. Fibrous joints connect the bones of the skull, providing stability with little to no movement. These joints are made of fibrous connective tissue, which holds the bones tightly together and prevents movement, making them ideal for the structure of the skull. Choice A: Hinge joint is incorrect because hinge joints allow movement in a single plane like the elbow or knee, which is not characteristic of the joints in the skull. Choice C: Ball-and-socket joint is incorrect as this type of joint allows for a wide range of movement in multiple planes, such as the hip and shoulder joints, which is not the case for skull bones. Choice D: Pivot joint is incorrect as pivot joints allow rotation around a central axis, as seen in the joint between the first and second cervical vertebrae (atlas and axis), but not in the skull bones.

4. What is the definition of a homophone?

• A. Words with opposite meanings
• B. Words that sound the same
• C. Synonyms
• D. Words with similar spellings

Correct answer: B

Rationale: The correct definition of a homophone is a word that sounds the same as another word but has a different meaning and often different spelling. Choice A, 'Words with opposite meanings,' is incorrect as homophones do not necessarily have opposite meanings. Choice C, 'Synonyms,' is incorrect because homophones are not words with the same meaning. Choice D, 'Words with similar spellings,' is also incorrect as homophones may have different spellings.

5. Which of the following sentences correctly uses a semicolon?

• A. I have a big test tomorrow; I can't go out tonight.
• B. I have a big test tomorrow; I can't go out tonight.
• C. I have a big test tomorrow; and I can't go out tonight.
• D. I have a big test tomorrow; but I can't go out tonight.

Correct answer: A

Rationale: The correct use of a semicolon is to join two closely related independent clauses. Choice A is the only option that correctly uses a semicolon to connect two independent clauses: 'I have a big test tomorrow' and 'I can't go out tonight.' Choice B incorrectly uses a comma instead of a semicolon. Choice C adds an unnecessary 'and' after the semicolon, which disrupts the correct punctuation usage. Choice D introduces a contradictory conjunction 'but' after the semicolon, which is not necessary for the given context. Therefore, the correct answer is A.
