1. Which type of muscle is responsible for moving the skeleton?

• A. Cardiac muscle
• B. Skeletal muscle
• C. Smooth muscle
• D. Voluntary muscle

Correct answer: B

Rationale: Skeletal muscle is the correct answer as it is responsible for moving the skeleton. Skeletal muscles are under voluntary control, meaning they can be consciously controlled by the individual. Cardiac muscle (Choice A) is found in the heart and is responsible for pumping blood, not moving the skeleton. Smooth muscle (Choice C) is found in internal organs and is responsible for involuntary movements like digestion. Voluntary muscle (Choice D) is not a specific type of muscle; it refers to muscles that can be consciously controlled, which includes skeletal muscles.

2. What is the main consequence of a malfunctioning thyroid gland that produces abnormally low levels of thyroid hormones?

• A. Increased energy levels and weight loss
• B. Decreased heart rate and body temperature
• C. Enhanced muscle growth and bone development
• D. Faster metabolism and heightened alertness

Correct answer: B

Rationale: The correct answer is B: Decreased heart rate and body temperature. A malfunctioning thyroid gland that produces abnormally low levels of thyroid hormones leads to hypothyroidism, resulting in decreased metabolic activity. This reduction in metabolic rate can cause a decreased heart rate and lower body temperature. Choices A, C, and D are incorrect because hypothyroidism typically manifests as symptoms such as fatigue, weight gain, cold intolerance, bradycardia, and decreased body temperature, rather than increased energy levels, enhanced muscle growth, faster metabolism, or heightened alertness.

3. What property of a wave determines its loudness in sound waves?

• A. Amplitude
• B. Wavelength
• C. Frequency
• D. Speed

Correct answer: A

Rationale: The correct answer is Amplitude. Amplitude is the property of a wave that determines its loudness in sound waves. The greater the amplitude of a sound wave, the louder the sound will be perceived. Wavelength and frequency are related to the pitch of the sound, with wavelength affecting the tone quality and frequency determining the pitch. Speed, on the other hand, is a characteristic of how fast the wave travels through a medium and does not directly influence the loudness of the sound.

4. Which of the following are the abdominal quadrants?

• A. RUQ, RLQ, LLQ, LUQ
• B. RUQ, LUQ, RLQ, LLQ
• C. LUQ, RUQ, LLQ, RLQ
• D. LLQ, LUQ, RUQ, RLQ

Correct answer: B

Rationale: The correct answer is B: RUQ, LUQ, RLQ, LLQ. The four abdominal quadrants are named as follows: Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), and Left Lower Quadrant (LLQ). These quadrants are used in healthcare to describe specific areas of the abdomen during assessments and discussions related to abdominal anatomy and pathology. Choices A, C, and D are incorrect because they do not follow the standard order of the abdominal quadrants.

5. Which of the following organs does not belong with the others?

• A. Thyroid gland
• B. Stomach
• C. Intestines
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.
