1. Which is a byproduct of fermentation in muscle cells?

• A. Ethanol
• B. Pyruvic acid
• C. Lactic acid
• D. Oxygen

Correct answer: C

Rationale: Lactic acid is a byproduct of fermentation in muscle cells. During intense exercise or when oxygen is limited, muscle cells use anaerobic respiration to generate energy. This process breaks down glucose into lactic acid, which can cause muscle fatigue and soreness. Choice A, Ethanol, is not produced in muscle cells during fermentation. Choice B, Pyruvic acid, is an intermediate product in glucose metabolism but is not a byproduct of fermentation in muscle cells. Choice D, Oxygen, is not a byproduct of fermentation but a reactant in aerobic respiration.

2. A note in the patient’s medical record states 'ANTICIPATORY GRIEVING'. Which patient situation below explains this type of grieving?

• A. A patient who has just given birth to twins following a long labor
• B. A patient who will have their left leg amputated below the knee tomorrow
• C. A patient experiencing pain during a physical therapy session
• D. A patient who will be discharged tomorrow after two months of being hospitalized

Correct answer: B

Rationale: The correct answer is B because 'anticipatory grieving' refers to the process of grieving in anticipation of a significant loss or change. In this case, a patient who is expecting a leg amputation tomorrow is experiencing anticipatory grieving as they are grieving the loss of a limb before it actually occurs. Choices A, C, and D do not involve an impending significant loss or change that would lead to anticipatory grieving.

3. What is the best description for the term septic?

• A. Infected
• B. Odorous
• C. Terminal
• D. Vigorous

Correct answer: A

Rationale: The term septic typically refers to something that is infected or contaminated with harmful bacteria or toxins, often used in the context of septic tanks or infections. Therefore, the correct answer is 'Infected.' Choices B, C, and D are incorrect. Odorous means having a smell, terminal means leading to death or the end of something, and vigorous means strong or energetic. These terms do not capture the essence of septic as being infected.

4. Which type of change occurs when no change is made to the chemical composition of a substance?

• A. Chemical
• B. Physical
• C. Nuclear
• D. Mechanical

Correct answer: B

Rationale: A physical change refers to alterations in the state of matter without modifying the chemical composition of the substance. Examples of physical changes include changes in state (solid, liquid, gas), shape, size, or phase. In a physical change, the substance may look different or behave differently, but its chemical structure remains the same. On the other hand, chemical changes involve the breaking and forming of chemical bonds, resulting in the creation of entirely new substances with different chemical properties. Nuclear changes involve alterations in the nucleus of an atom, such as radioactive decay. Mechanical changes refer to changes in the position or motion of an object caused by applied forces, like pushing, pulling, or twisting.

5. If Alice consumes twice as many calories as Claire, and Claire consumes 2,500 calories a day, how many calories does Alice consume per week?

• A. 17,500
• B. 15,000
• C. 22,500
• D. 35,000

Correct answer: D

Rationale: If Claire consumes 2,500 calories a day, Alice, consuming twice as many calories as Claire, would consume 2 * 2,500 = 5,000 calories per day. To find out how many calories Alice consumes per week, we multiply her daily consumption by 7 (days in a week): 5,000 * 7 = 35,000 calories. Therefore, Alice consumes 35,000 calories per week. Choices A, B, and C are incorrect because they do not account for Alice consuming twice as many calories as Claire.
