Nursing Elites

1. Describe the ethical considerations surrounding the potential use of CRISPR-Cas9 technology in humans.

• A. Concerns about unintended consequences on the genome and potential off-target effects.
• B. Debates on modifying the human germline and potential eugenic implications.
• C. Accessibility and affordability of the technology, ensuring equitable access to benefits.
• D. Risks associated with CRISPR-Cas9 editing germline cells and potential long-term impacts.

Correct answer: B

Rationale: CRISPR-Cas9's ability to precisely edit germline cells raises ethical dilemmas about modifying the human gene pool. This includes concerns about eugenics, unintended consequences, and the long-term impact on future generations.

2. What is the name of the master gland that regulates the function of many other endocrine glands?

• A. Thyroid gland
• B. Pituitary gland
• C. Hypothalamus
• D. Adrenal gland

Correct answer: B

Rationale: The correct answer is B: Pituitary gland. The pituitary gland is often referred to as the 'master gland' because it plays a crucial role in regulating the function of many other endocrine glands in the body. It secretes hormones that control various processes such as growth, metabolism, and reproduction. The thyroid gland (A) primarily regulates metabolism, the hypothalamus (C) helps control the pituitary gland, and the adrenal gland (D) produces hormones involved in stress response. Therefore, the pituitary gland is the main gland responsible for coordinating the activities of other endocrine glands, earning it the title of the master gland.

3. Which property of matter explains why ice floats on water?

• A. Viscosity
• B. Density
• C. Buoyancy
• D. Surface tension

Correct answer: c

Rationale: Buoyancy is the upward force exerted by a fluid (like water) on an object immersed in it. Ice floats on water because it is less dense than water, experiencing an upward force (buoyancy) greater than its weight.

4. What is the main component of sweat?

• A. Urea
• B. Glucose
• C. Water
• D. Electrolytes

Correct answer: C

Rationale: Rationale: - Sweat is primarily composed of water, making up the majority of its content. Water helps regulate body temperature by evaporating from the skin's surface, which cools the body down. - While sweat does contain small amounts of other substances like urea, glucose, and electrolytes, water is the main component that is secreted by sweat glands to help regulate body temperature during physical activity or in response to heat.

5. What is the periodic law?

• A. The statement that the properties of the elements are a periodic function of their atomic numbers.
• B. The statement that the elements can be arranged in a table in which elements with similar properties are grouped together
• C. The statement that the elements can be arranged in a table in which the atomic number of an element is equal to the number of protons in its nucleus
• D. The statement that the elements can be arranged in a table in which the atomic mass of an element is equal to the number of neutrons in its nucleus.

Correct answer: A

Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.

6. When Harry uses team nursing as a care delivery system, he and his team need to assess the

• A. Each patient as listed on the worksheet
• B. Patients who needs least care
• C. Medications and treatments required for all patients
• D. Patients who need the most care

Correct answer: C

Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.
