1. If Mom's car drove 72 miles in 90 minutes, how fast did she drive in feet per second?

• A. 0.8 feet per second
• B. 48.9 feet per second
• C. 0.009 feet per second
• D. 70.4 feet per second

Correct answer: D

Rationale: To convert miles per hour to feet per second, first convert time to hours: 90 minutes = 1.5 hours. Then, calculate the speed in miles per hour: 72 miles in 1.5 hours = 48 mph. Finally, convert mph to feet per second using the conversion factor 1 mph = 1.47 feet per second: 48 mph * 1.47 = 70.4 feet per second. Therefore, the correct answer is 70.4 feet per second. Choices A, B, and C are incorrect because they do not reflect the correct conversion from miles per hour to feet per second.

2. The brain is part of which system?

• A. Integumentary system
• B. Nervous system
• C. Endocrine system
• D. Respiratory system

Correct answer: B

Rationale: The brain is a crucial organ that serves as the command center of the body, making it a key component of the nervous system. It processes sensory information, coordinates movements, and regulates various bodily functions. Therefore, the brain is correctly categorized as part of the nervous system. Choices A, C, and D are incorrect because the integumentary system pertains to the skin, the endocrine system involves hormone regulation, and the respiratory system is responsible for breathing. These systems do not encompass the brain's functions or structure.

3. 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 levels. While blood oxygen levels are crucial for overall health, they are not directly reflected in a blood pressure reading.

Correct answer: D

Rationale: Blood oxygen saturation levels are essential for overall health but are not directly part of a blood pressure reading. A healthy blood pressure reading consists of systolic pressure, diastolic pressure, and pulse pressure. Systolic pressure represents the peak pressure during ventricular contraction, diastolic pressure reflects the pressure within arteries during ventricular relaxation, and pulse pressure is the difference between systolic and diastolic pressure. These components collectively provide information about the pressure variations within the arteries throughout the cardiac cycle phases, contributing to the assessment of cardiovascular health. Therefore, choice D, blood oxygen saturation levels, is not a major component of a healthy blood pressure reading and is the correct answer. Choices A, B, and C are major components of a healthy blood pressure reading and directly relate to the pressure variations within the arteries during different phases of the cardiac cycle.

4. Which word is most closely associated with the adjective 'meticulous'?

• A. careless
• B. precise
• C. indifferent
• D. enthusiastic

Correct answer: B

Rationale: The word 'meticulous' is synonymous with being very careful and detail-oriented. It describes someone who pays close attention to detail and is thorough in their work. 'Precise' is the best choice among the options as it conveys accuracy and exactness, which align with the nature of someone who is meticulous. Choice A, 'careless,' is the opposite of meticulous, indicating a lack of attention to detail. Choice C, 'indifferent,' suggests a lack of interest or concern, which is not related to being meticulous. Choice D, 'enthusiastic,' conveys a sense of excitement and passion rather than the precision and carefulness associated with being meticulous.

5. What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?

• A. Dehydration
• B. Kidney failure
• C. Incontinence
• D. Nephritis

Correct answer: B

Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.
