1. Which of the following is a characteristic of a solution with a high viscosity?

• A. It flows easily
• B. It has a low resistance to flow
• C. It has a high resistance to flow
• D. It does not mix with other liquids

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.

2. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

• A. Advise her staff to go on vacation.
• B. Ignore her observations; it will be resolved even without intervention
• C. Remind her to show loyalty to the institution.
• D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.

3. A set of temperature readings has a range of 5 degrees Celsius. What does this tell you about the data?

• A. The average temperature is 5 degrees Celsius.
• B. All temperatures are within 5 degrees of each other.
• C. The difference between the highest and lowest temperatures is 5 degrees.
• D. There are exactly 5 temperatures in the set.

Correct answer: C

Rationale: Rationale: - Option A is incorrect because the range of 5 degrees does not necessarily mean that the average temperature is 5 degrees Celsius. The average temperature could be any value within the range. - Option B is incorrect because the range of 5 degrees does not mean that all temperatures are within 5 degrees of each other. It only indicates the difference between the highest and lowest temperatures. - Option C is correct because the range of 5 degrees specifically refers to the difference between the highest and lowest temperatures in the set. This is a common definition of range in statistics. - Option D is incorrect because the range of 5 degrees does not determine the number of temperatures in the set. The set could have more or fewer than 5 temperatures.

4. The innate immune system provides:

• A. Nonspecific, immediate defense against pathogens
• B. Specific, long-term immune response through memory cells
• C. Both (a) and (b)
• D. Neither (a) nor (b)

Correct answer: A

Rationale: The correct answer is A: 'Nonspecific, immediate defense against pathogens.' The innate immune system is the body's first line of defense against pathogens and provides a rapid, nonspecific response. It includes physical barriers like the skin, chemical barriers like stomach acid, and cellular responses like inflammation. This system does not involve memory cells or provide long-term immunity, which are characteristics of the adaptive immune system. Therefore, option A accurately describes the function of the innate immune system as a quick and nonspecific defense mechanism.

5. An ancient Egyptian pyramid has a square base with side lengths of 20 meters and a remaining height (after erosion) of 10 meters. Its original height was 30 meters. What was the volume of the pyramid in its original state?

• A. 12000 cu m
• B. 6000 cu m
• C. 18000 cu m
• D. 24000 cu m

Correct answer: A

Rationale: Use the formula for the volume of a pyramid with the original height and base area.

6. Which of the following is NOT a major component of a healthy blood pressure reading?

• A. Systolic pressure (peak pressure during ventricular contraction).
• B. Diastolic pressure (pressure within arteries during ventricular relaxation).
• C. Pulse pressure (difference between systolic and diastolic pressure).
• D. Blood oxygen saturation While blood oxygen levels are crucial for overall health, they are not directly reflected in a blood pressure reading.

Correct answer: A

Rationale: The correct answer is A. Systolic pressure is a major component of a healthy blood pressure reading as it represents the peak pressure in the arteries during ventricular contraction. Diastolic pressure, representing the pressure in the arteries during ventricular relaxation, is also a key component. Pulse pressure, the difference between systolic and diastolic pressure, provides additional information about the cardiovascular system. Blood oxygen saturation, while important for overall health, is not directly measured in a blood pressure reading. Therefore, it is not a major component of a healthy blood pressure reading.
