Nursing Elites

1. What is the functional group present in amines?

• A. Hydroxyl
• B. Carbonyl
• C. Amine
• D. Nitro

Correct answer: C

Rationale: Amines have the functional group -NHâ‚‚. The other choices are associated with different functional groups.

2. The stratified squamous epithelium found in the skin is adapted for:

• A. Absorption
• B. Secretion
• C. Protection
• D. Gas exchange

Correct answer: C

Rationale: The correct answer is C: Protection. Stratified squamous epithelium is a type of tissue that is well-suited for protection as it consists of multiple layers of cells that provide a barrier against physical and chemical damage. In the skin, this epithelium helps protect the body against external threats such as pathogens, UV radiation, and mechanical abrasion. Absorption (A) and secretion (B) are typically functions of other types of epithelial tissues, such as simple columnar or simple cuboidal epithelium. Gas exchange (D) is primarily facilitated by tissues like the alveolar epithelium in the lungs, not stratified squamous epithelium in the skin.

3. Which technology allows scientists to directly edit the human genome?

• A. Polymerase Chain Reaction (PCR)
• B. Gel electrophoresis
• C. DNA sequencing
• D. CRISPR-Cas9

Correct answer: D

Rationale: Rationale: A) Polymerase Chain Reaction (PCR) is a technique used to amplify a specific segment of DNA through repeated cycles of heating and cooling. PCR is not used for directly editing the human genome. B) Gel electrophoresis is a technique used to separate DNA fragments based on size. It is not used for directly editing the human genome. C) DNA sequencing is a method used to determine the precise order of nucleotides in a DNA molecule. While DNA sequencing is important for understanding genetic information, it is not used for directly editing the human genome. D) CRISPR-Cas9 is a technology that allows scientists to make precise changes to the DNA of living organisms, including the human genome. CRISPR-Cas9 works by guiding the Cas9 enzyme to a specific location in the genome where it can make targeted cuts or edits. This technology has revolutionized genetic research and has the potential for applications

4. Which of the following statements best describes Newton's first law of motion?

• A. An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted upon by an external force.
• B. Force equals mass times acceleration.
• C. For every action, there is an equal and opposite reaction.
• D. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Correct answer: A

Rationale: Newton's first law of motion, also known as the law of inertia, states that an object in motion will remain in motion, and an object at rest will remain at rest unless acted upon by an external force. This principle highlights the concept of inertia, which is the tendency of objects to resist changes in their state of motion. Option A accurately captures this fundamental aspect of Newton's first law. Options B, C, and D describe Newton's second law, third law, and the relationship between force, acceleration, and mass, respectively.

5. Functional nursing has some advantages, which one is an EXCEPTION?

• A. Psychological and sociological needs are emphasized.
• B. Great control of work activities.
• C. Most economical way of delivering nursing services.
• D. Workers feel secure in dependent role

Correct answer: B

Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.

6. Which of the following statements refers to criteria?

• A. Agreed on level of nursing care
• B. Characteristics used to measure the level of nursing care
• C. Step-by-step guidelines
• D. Statement which guide the group in decision making and problem solving

Correct answer: B

Rationale: Criteria are specific characteristics or standards used to evaluate or measure the quality or level of something. In this case, statement B, 'Characteristics used to measure the level of nursing care,' correctly refers to criteria because it highlights the specific attributes that are used to assess the quality or level of nursing care provided. The other options do not directly address the concept of criteria. Option A describes an agreed-upon level of care but does not specifically refer to criteria. Option C describes step-by-step guidelines, which are more related to processes or procedures. Option D mentions statements that guide decision-making and problem-solving, which are not necessarily criteria. Therefore, option B is the most appropriate choice as it directly aligns with the definition and concept of criteria.
