Nursing Leadership and Management
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. In the process of osmosis, the solvent moves from an area of...
- A. Low solute concentration to high solute concentration
- B. Hotter solution to colder solution
- C. Colder solution to hotter solution
- D. High solute concentration to low solute concentration
Correct answer: D
Rationale: In osmosis, solvent molecules move across a semi-permeable membrane from an area of low solute concentration to high solute concentration. This movement is driven by the desire to equalize the concentration of solutes on both sides of the membrane. As a result, option A is the correct answer because the solvent will naturally flow towards the area with a higher concentration of solutes in order to balance the concentrations on both sides of the membrane. Options B and C are incorrect as osmosis is not influenced by temperature differences. Option D is incorrect as the solvent does not move towards areas of high solute concentration in osmosis.
3. Which term refers to the resistance of a liquid to flow?
- A. Density
- B. Viscosity
- C. Surface tension
- D. Boiling point
Correct answer: B
Rationale: Viscosity is the term that refers to the resistance of a liquid to flow. It is a measure of how thick or sticky a fluid is, and it determines how easily a liquid can flow. Density (A) is a measure of how much mass is contained in a given volume, surface tension (C) is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules, and boiling point (D) is the temperature at which a liquid changes to a vapor.
4. The term "bioaccumulate" refers to...
- A. The natural decomposition of organic materials.
- B. The buildup of a substance in living organisms.
- C. The contamination of seawater with chemical pollutants.
- D. The physical entanglement of animals with plastic debris.
Correct answer: B
Rationale: The passage describes microplastics entering food chains and accumulating in organisms, aligning with bioaccumulation.
5. What is the name of the muscular ring that controls the passage of food from the esophagus to the stomach?
- A. Pyloric sphincter
- B. Cardiac sphincter
- C. Ileocecal valve
- D. Sphincter of Oddi
Correct answer: B
Rationale: The correct answer is B: Cardiac sphincter. The cardiac sphincter, also known as the lower esophageal sphincter, is the muscular ring located at the junction between the esophagus and the stomach. It controls the passage of food from the esophagus into the stomach by opening and closing to prevent reflux of stomach contents back into the esophagus. The other options are incorrect: A) The pyloric sphincter is located at the junction between the stomach and the small intestine, controlling the passage of food from the stomach into the small intestine. C) The ileocecal valve is located between the small intestine and the large intestine. D) The Sphincter of Oddi is located in the duodenum and regulates the flow of bile and pancreatic juice into the small intestine. Therefore, the correct answer is B because it specifically relates to the passage of food from the esophagus to the stomach.
6. When unpolarized light passes through a polarizing filter, the intensity of the transmitted light is:
- A. Completely absorbed
- B. Reduced by half
- C. Unaffected
- D. Doubled
Correct answer: B
Rationale: When unpolarized light passes through a polarizing filter, the intensity of the transmitted light is reduced by half. This is because a polarizing filter only allows light waves oscillating in one plane to pass through while blocking the other perpendicular plane. Unpolarized light consists of waves oscillating in all possible planes, so when it passes through the polarizer, only half of the light waves aligned with the filter's polarization direction can transmit through. As a result, the intensity of the transmitted light is reduced by half as only a portion of the original light waves can pass through the filter.
