TEAS Test 7 science quizlet
1. Why is warming up before exercise important?
- A. To prevent dehydration
- B. To prevent muscle soreness
- C. To prevent increased heart rate
- D. To prevent low blood sugar
Correct answer: B
Rationale: Warming up before exercise is crucial to prevent muscle soreness. It helps by increasing blood flow to the muscles, improving flexibility, and preparing the body for physical activity. Dehydration, increased heart rate, and low blood sugar are not directly prevented by warming up before exercise. Dehydration is prevented by proper hydration before and during exercise; increased heart rate is a normal physiological response to exercise; and low blood sugar is managed through proper nutrition and timing of meals before physical activity.
2. Where would a nonpregnant patient with normal anatomy most commonly have pain in acute appendicitis?
- A. Right upper quadrant.
- B. Left upper quadrant.
- C. Right lower quadrant.
- D. Left lower quadrant.
Correct answer: C
Rationale: In acute appendicitis, nonpregnant patients with normal anatomy commonly experience pain in the right lower quadrant of the abdomen. The pain usually starts around the umbilicus or epigastric area and then migrates to the right lower quadrant as inflammation progresses in the appendix. This classic migration of pain is known as McBurney's point tenderness and is a key clinical feature in diagnosing appendicitis.
3. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:
- A. A smaller force
- B. An equal force
- C. A greater force
- D. No force at all
Correct answer: B
Rationale: According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push against a wall with a certain force, the wall will push back on you with an equal force in the opposite direction. Choice A is incorrect because the wall exerts an equal force back. Choice C is incorrect as it suggests a greater force, which goes against Newton's third law. Choice D is incorrect as the wall does exert a force back in response to your push.
4. The tonsils and adenoids are part of the lymphatic system located in the:
- A. Chest cavity
- B. Abdominal cavity
- C. Head and neck region
- D. Pelvic cavity
Correct answer: C
Rationale: The tonsils and adenoids are lymphatic tissues located in the head and neck region, specifically in the throat area. They are essential components of the immune system, acting as the first line of defense against infections that can enter through the nose and mouth. The tonsils are situated at the back of the throat, while the adenoids are positioned high in the throat behind the nose. Choices A, B, and D are incorrect as they do not correspond to the anatomical location of the tonsils and adenoids. Therefore, the correct answer is the head and neck region.
5. Which type of joint allows for rotational movement around a single axis?
- A. Ball-and-socket joint
- B. Pivot joint
- C. Hinge joint
- D. Saddle joint
Correct answer: B
Rationale: The correct answer is a Pivot joint. A pivot joint, like the joint in the neck, enables rotational movement around a single axis. This type of joint is crucial for allowing the head to turn from side to side. Choice A, Ball-and-socket joint, allows for movement in multiple axes due to its spherical structure, not limited to single-axis rotation. Choice C, Hinge joint, allows movement in one plane like a door hinge, but not rotational movement around a single axis. Choice D, Saddle joint, allows movement in multiple directions but is not specifically designed for rotational movement around a single axis.
