Nursing Elites

1. The stratified cuboidal epithelium lining the salivary glands is responsible for:

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

Correct answer: C

Rationale: The correct answer is C: Secretion. The stratified cuboidal epithelium lining the salivary glands is specifically designed for the secretion of saliva, which plays a crucial role in the initial digestion of food. This type of epithelium has multiple layers of cells that provide protection and support for the glandular tissue underneath, allowing for the production and release of saliva. Options A, B, and D are incorrect as they do not accurately reflect the primary function of this particular epithelium. Therefore, the correct choice is C, secretion.

2. Identify the interrogative sentence in the following options:

• A. The delicious pie disappeared quickly.
• B. What is your favorite color?
• C. Please open the window.
• D. He ran as fast as he could.

Correct answer: B

Rationale: An interrogative sentence asks a question and typically ends with a question mark.

3. How does the structure of centromeres contribute to chromosome movement during mitosis?

• A. The centromere provides a binding site for spindle fibers, allowing chromosomes to be attached and manipulated.
• B. The centromere serves as a dividing point between sister chromatids, ensuring their separation during anaphase.
• C. The centromere maintains chromosome stability by preventing chromosomal breaks and rearrangements.
• D. The centromere plays a role in DNA replication, ensuring accurate copying of the genetic material.

Correct answer: A

Rationale: Rationale: A) The centromere provides a binding site for spindle fibers, which are microtubules that help move chromosomes during cell division. This attachment allows the chromosomes to be pulled towards opposite poles of the cell during mitosis. Therefore, the structure of centromeres directly contributes to chromosome movement during mitosis by facilitating the attachment and manipulation of chromosomes by the spindle fibers. B) While the centromere does serve as a dividing point between sister chromatids, ensuring their separation during anaphase, this function is more related to the segregation of chromosomes rather than their movement. C) The centromere does play a role in maintaining chromosome stability by ensuring proper chromosome segregation, but it is not primarily responsible for preventing chromosomal breaks and rearrangements. D) The centromere is not directly involved in DNA replication. Its main function is

4. Which hormone plays a key role in stimulating the release of milk from breast tissue after childbirth?

• A. Follicle-stimulating hormone (FSH)
• B. Luteinizing hormone (LH)
• C. Prolactin
• D. Estrogen

Correct answer: C

Rationale: The correct answer is C: Prolactin. Prolactin is the hormone responsible for stimulating the production and release of milk from breast tissue after childbirth. It is produced by the pituitary gland and plays a crucial role in lactation. FSH and LH are reproductive hormones involved in the menstrual cycle and ovulation, not milk production. Estrogen is a sex hormone that plays a role in the development of female reproductive organs. Therefore, the hormone that specifically stimulates milk release from breast tissue after childbirth is prolactin.

5. What is the relationship between work, force, and displacement?

• A. Work is directly proportional to force but inversely proportional to displacement
• B. Work is directly proportional to both force and displacement
• C. Work is inversely proportional to force but directly proportional to displacement
• D. Work is inversely proportional to both force and displacement

Correct answer: b

Rationale: Work done is the product of force and displacement in the direction of the force.

6. St. Raphael Medical Center just opened its new Performance Improvement Department. Ms.

• A. Make an interpretation about strengths and weaknesses
• B. Identify the values of the department
• C. Identify structure, process, outcome standards & criteria
• D. Measure actual performances

Correct answer: B

Rationale: The correct answer is B: 'Identify the values of the department.' When a new department is established, it is important to define its core values, beliefs, and principles to guide its operations. This helps create a shared understanding among staff and stakeholders about the department's purpose and priorities. By identifying the values of the Performance Improvement Department at St. Raphael Medical Center, employees can align their actions with the department's mission and goals, fostering a cohesive and effective work environment. Options A, C, and D are not directly related to establishing the foundational values of a new department, making them less relevant in this context.
