1. Which division of the peripheral nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, enabling voluntary muscle movements?

• A. Somatic nervous system
• B. Autonomic nervous system
• C. Sympathetic nervous system
• D. Parasympathetic nervous system

Correct answer: a

Rationale: The correct answer is A: Somatic nervous system. The somatic nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, allowing for voluntary muscle movements. This division controls conscious movements such as walking, talking, and picking up objects. The autonomic nervous system (option B) controls involuntary functions like heart rate and digestion, while the sympathetic (option C) and parasympathetic (option D) nervous systems are subcategories of the autonomic system and regulate the body's responses to stress and relaxation, respectively. Therefore, the somatic nervous system is the correct division responsible for voluntary muscle movements.

2. What describes the change in direction of light when it passes through different mediums, such as air and water?

• A. Diffraction
• B. Reflection
• C. Refraction
• D. Dispersion

Correct answer: c

Rationale: Refraction is the bending of light as it passes from one medium to another with different optical densities, causing a change in direction.

3. Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

• A. ATP (Adenosine Triphosphate)
• B. Glucose
• C. Myoglobin
• D. Lactic Acid

Correct answer: a

Rationale: The correct answer is A: ATP (Adenosine Triphosphate). ATP is known as the energy currency of the cell and is responsible for storing and providing quick energy during short bursts of intense physical activity. When muscles require immediate energy for activities like weightlifting or sprinting, ATP is broken down to release energy rapidly. Glucose is a source of energy but needs to be converted into ATP before it can be used by the muscles. Myoglobin is a protein that stores oxygen in muscle cells, not energy. Lactic Acid is produced during intense exercise but is not a direct source of quick energy like ATP.

4. Aubrey thinks about primary nursing as a system to deliver care. Which of the following

• A. Collaborates with the physician
• B. Provides care to a group of patients together with a group of nurses
• C. Provides care for 5-6 patients during their hospital stay.
• D. Performs comprehensive initial assessment

Correct answer: D

Rationale: Primary nursing is a care delivery system where one nurse is responsible for the total nursing care needs of a group of patients throughout their hospital stay. This includes performing comprehensive initial assessments, developing care plans, coordinating with other healthcare team members, and providing direct patient care. Option D is the correct answer as it aligns with the core principles of primary nursing, emphasizing the nurse's role in conducting thorough assessments to ensure individualized and holistic care for each patient in their caseload. Options A, B, and C do not accurately reflect the key components of primary nursing, making them incorrect choices.

5. A person throws a ball horizontally. What force changes the direction of the ball's motion?

• A. The force of throwing
• B. Gravitational force
• C. Air resistance
• D. Normal force from the ground

Correct answer: B

Rationale: When a person throws a ball horizontally, the initial force that propels the ball forward is the force of throwing (A). However, the force that changes the direction of the ball's motion is the gravitational force (B), which acts vertically downward and causes the ball to follow a curved path. Air resistance (C) and normal force from the ground (D) do not directly change the direction of the ball's motion in this scenario.

6. Which of the following is NOT a common symptom of lactose intolerance?

• A. Gas
• B. Bloating
• C. Diarrhea
• D. Nausea

Correct answer: D

Rationale: Rationale: A) Gas: Gas is a common symptom of lactose intolerance. When lactose is not properly digested, it can ferment in the colon, leading to the production of gas. B) Bloating: Bloating is another common symptom of lactose intolerance. The buildup of gas in the digestive system can cause bloating and discomfort. C) Diarrhea: Diarrhea is a common symptom of lactose intolerance. When lactose is not broken down in the small intestine, it can draw excess water into the colon, resulting in diarrhea. D) Nausea: Nausea is not a common symptom of lactose intolerance. While some individuals may experience mild stomach discomfort or cramps, nausea is not typically associated with lactose intolerance.
