Nursing Leadership and Management

1. Alexandra is tasked to organize the new wing of the hospital. She was given the authority to

Correct answer: D

Rationale: The correct answer is D: Participative. In a participative leadership style, Alexandra would involve the team members in decision-making and encourage their input when organizing the new wing of the hospital. This approach fosters collaboration, empowers team members, and can lead to better outcomes as everyone's perspectives are considered. Benevolent-authoritative (A) involves a leader who is kind and caring but makes decisions independently. Consultative (B) involves seeking input from team members but making the final decision independently. Exploitive-authoritative (C) involves a leader who uses their authority in a self-serving or oppressive manner. In this scenario, with the task of organizing a new wing of the hospital, a participative approach would be most effective in engaging the team and utilizing their expertise.

2. Imagine you have an element with atomic number 20 and mass number 40. How many neutrons does it have?

Correct answer: C

Rationale: Rationale: - The atomic number (Z) represents the number of protons in an atom. In this case, the atomic number is 20. - The mass number (A) represents the total number of protons and neutrons in an atom. In this case, the mass number is 40. - To find the number of neutrons, you subtract the atomic number from the mass number: Neutrons = Mass number - Atomic number. - Neutrons = 40 - 20 = 20. - Therefore, the element with atomic number 20 and mass number 40 has 20 neutrons.

3. Semen, the fluid that carries sperm, is produced by which of the following structures in the male reproductive system?

Correct answer: D

Rationale: The correct answer is D: Seminal vesicles. Semen is a mixture of fluids produced by various structures in the male reproductive system. The seminal vesicles are responsible for producing a significant portion of the fluid in semen, which provides nutrients and protection for sperm. The testes produce sperm, but the fluid that carries sperm, known as semen, is primarily produced by the seminal vesicles. The scrotum is the external sac that houses the testes, and the prostate gland also contributes to semen production, but the seminal vesicles play a key role in producing the fluid that carries sperm.

4. A birdbath has a hemispherical bowl with a diameter of 30cm. What is its volume?

Correct answer: C

Rationale: Use half the formula for a sphere's volume: (2/3) * π * (radius)^3. Calculate the radius (15cm) and substitute: (2/3) * π * (15cm)^3 ≈ 2700 cu cm.

5. The small intestine is where most of the chemical digestion and nutrient absorption occur. What is the finger-like projection in the small intestine that increases its surface area for absorption?

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' The finger-like projection in the small intestine that increases its surface area for absorption is primarily the villi and microvilli. Villi are small, finger-like projections that line the inner wall of the small intestine, while microvilli are even smaller projections on the surface of the villi. Both structures significantly increase the surface area of the small intestine, allowing for more efficient absorption of nutrients. Rugae, on the other hand, are folds in the stomach lining that help with expansion when the stomach is full. Therefore, the rugae are not directly related to the increased surface area for absorption in the small intestine, making options A and B incorrect choices. Overall, options A, B, and C are all related to the structure of the small intestine but serve different functions, so the most appropriate answer is D, 'All of the above.'

6. What is the main function of estuaries?

Correct answer: B

Rationale: Rationale: Estuaries are coastal areas where freshwater from rivers and streams mixes with saltwater from the ocean. They serve as important habitats for a variety of marine life, including fish, birds, and other wildlife. Estuaries provide shelter, breeding grounds, and food sources for many species, making them crucial for the overall health of marine ecosystems. While estuaries can help filter pollutants to some extent, their primary function is to support and sustain diverse populations of plants and animals. Storing carbon dioxide and generating wind power are not main functions of estuaries.
