Nursing Elites

1. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

• A. Possesses inspirational quality that makes followers gets attracted of him and regards
• B. Acts as he does because he expects that his behavior will yield positive results
• C. Uses visioning as the core of his leadership
• D. Matches his leadership style to the situation at hand.

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

2. When light interacts with a perfectly smooth surface, like a mirror, the dominant interaction is:

• A. Refraction
• B. Diffraction
• C. Total internal reflection
• D. Specular reflection

Correct answer: D

Rationale: The correct answer is D: Specular reflection. When light interacts with a perfectly smooth surface like a mirror, it undergoes specular reflection, where the light rays are reflected at the same angle as the incident angle. Refraction (option A) occurs when light passes from one medium to another at an angle, causing it to change direction. Diffraction (option B) is the bending of light waves around obstacles or through small openings. Total internal reflection (option C) occurs when light traveling in a medium strikes the boundary with another medium at an angle greater than the critical angle, causing the light to reflect back into the original medium. In the case of a perfectly smooth surface, specular reflection is the dominant interaction as the light rays reflect in a single direction with minimal scattering or diffraction.

3. What is the condition called when someone experiences a temporary loss of consciousness due to a lack of blood flow to the brain?

• A. Stroke
• B. Epilepsy
• C. Syncope (fainting)
• D. Multiple sclerosis

Correct answer: C

Rationale: The correct answer is C: 'Syncope (fainting)'. Syncope is the temporary loss of consciousness caused by a temporary drop in blood flow to the brain, leading to a lack of oxygen reaching the brain. This can occur due to various reasons such as dehydration, sudden drop in blood pressure, or emotional stress. A stroke (option A) is a sudden interruption in the blood supply to the brain, leading to brain cell damage. Epilepsy (option B) is a neurological disorder characterized by recurrent seizures. Multiple sclerosis (option D) is a chronic autoimmune disease that affects the central nervous system. Therefore, the correct term for a temporary loss of consciousness due to lack of blood flow to the brain is syncope.

4. What is the term for the shedding of the outermost layer of the epidermis?

• A. Desquamation
• B. Exfoliation
• C. Keratinization
• D. Epidermolysis

Correct answer: A

Rationale: The correct term for the shedding of the outermost layer of the epidermis is desquamation. Desquamation is a natural process where old skin cells are shed off to make way for new cells. Exfoliation refers to the removal of dead skin cells through external means like scrubs. Keratinization is the process by which skin cells produce the protein keratin, while epidermolysis is a condition where the epidermis separates from the dermis. Therefore, in this context, desquamation is the most appropriate term for the shedding of the outermost layer of the epidermis.

5. Which of the following numbers is the greatest common factor (GCF) of 12 and 18?

• A. 2
• B. 3
• C. 6
• D. 9

Correct answer: C

Rationale: The GCF is the largest number that is a factor of both 12 and 18. We can factor each number to find common factors: 12 = 2 x 2 x 3 and 18 = 2 x 3 x 3. The greatest common factor that appears in both factorizations is 6 (2 x 3).

6. What is the primary function of hair on the human body?

• A. Insulation
• B. Sensory perception
• C. Protection
• D. Vitamin D synthesis

Correct answer: A

Rationale: The primary function of hair on the human body is insulation. Hair acts as a protective layer to help regulate body temperature by trapping heat close to the skin. This insulation property is especially important in colder climates to prevent excessive heat loss from the body. While hair can also provide some level of protection from external elements and minor injuries, its main role is to insulate the body. Sensory perception is mainly attributed to nerve endings in the skin rather than hair. Vitamin D synthesis is primarily dependent on exposure to sunlight rather than hair. Therefore, option A, insulation, is the correct answer.
