1. What is the relationship between mass and weight on Earth's surface?
- A. Mass and weight are equal
- B. Mass is greater than weight
- C. Weight is greater than mass
- D. Mass and weight are not related
Correct answer: a
Rationale: On Earth's surface, mass and weight are directly proportional but not equal, as weight is the force due to gravity acting on an object's mass.
2. An IV drip delivers 40 drops per minute, each containing 1mg of medication. How many milligrams are administered in 3 hours (180 minutes)?
- A. 360mg
- B. 720mg
- C. 7,200mg
- D. 14,400mg
Correct answer: C
Rationale: Rationale: In this scenario, we first calculated the total number of drops administered in 3 hours by multiplying the drops per minute by the total number of minutes. Then, we converted the drops to milligrams by multiplying the total drops by the amount of medication in each drop. This method ensures an accurate calculation of the total amount of medication administered over the given time period.
3. 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).
4. 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.
5. Which of the following conclusions of Ms. Castro about leadership characteristics is TRUE?
- A. There is a high correlation between the communication skills of a leader and the ability to get
- B. A manager is effective when he has the ability to plan well.
- C. Assessment of personal traits is a reliable tool for predicting a manager’s potential.
- D. There is good evidence that certain personal qualities favor success in managerial role.
Correct answer: A
Rationale: The correct answer is A because effective communication skills are essential for a leader to successfully convey ideas, motivate teams, and build relationships. Strong communication skills enable a leader to articulate goals clearly, listen to feedback, and resolve conflicts efficiently. This correlation between communication skills and leadership effectiveness has been well-documented in numerous studies. In contrast, options B, C, and D are not universally true statements about leadership characteristics. While planning skills and personal traits may contribute to effective leadership, they are not as directly linked to leadership success as communication skills. Therefore, option A is the most accurate conclusion about leadership characteristics among the choices provided.
6. The hormone responsible for the "fight-or-flight" response in stressful situations is produced by the:
- A. Thyroid gland
- B. Pituitary gland
- C. Adrenal gland
- D. Pancreas
Correct answer: C
Rationale: The correct answer is C: Adrenal gland. The adrenal gland is responsible for producing the hormone known as adrenaline, which triggers the 'fight-or-flight' response in stressful situations. This response prepares the body to either confront the stressor or flee from it. The thyroid gland (A) is responsible for producing hormones that regulate metabolism, growth, and development. The pituitary gland (B) controls several other endocrine glands and produces a variety of hormones. The pancreas (D) is responsible for producing insulin and glucagon, which regulate blood sugar levels but are not directly involved in the 'fight-or-flight' response.
