ATI TEAS English and Language Usage
1. Which of the following is a complete sentence?
- A. Under the bed.
- B. Although he tried his best.
- C. Running through the park.
- D. She ran through the park.
Correct answer: D
Rationale: The correct answer is D, 'She ran through the park.' This sentence is a complete sentence as it contains both a subject 'She' and a predicate 'ran through the park.' Choices A, B, and C are not complete sentences because they lack either a subject, a predicate, or both. Choice A 'Under the bed.' lacks a verb or predicate, choice B 'Although he tried his best.' is a dependent clause and does not form a complete sentence on its own, and choice C 'Running through the park.' is a phrase without a subject or a complete predicate.
2. Which of the following choices best describes the location of the trachea in relation to the esophagus?
- A. Lateral
- B. Anterior
- C. Posterior
- D. Dorsal
Correct answer: B
Rationale: The trachea is situated in front of the esophagus, making it anterior to the esophagus. This anatomical relationship is crucial to understand in clinical practice, particularly regarding airway management and esophageal intubation. Therefore, the correct answer is B: 'Anterior.' Choices A, C, and D are incorrect because the trachea is not located to the side (lateral), behind (posterior), or on the back (dorsal) of the esophagus.
3. What is the formula for calculating molarity?
- A. M = n/V
- B. M = n/L
- C. M = mol/L
- D. M = mol/dm³
Correct answer: A
Rationale: The correct formula for calculating molarity is M = n/V. In this formula, 'M' represents molarity, 'n' represents the number of moles of solute, and 'V' represents the volume of the solution in liters. Molarity is defined as the number of moles of solute per liter of solution, hence the ratio of moles to volume. Choice B, 'M = n/L', is incorrect because 'L' should represent liters instead of the number of moles. Choice C, 'M = mol/L', is incorrect as it does not include the representation of the number of moles 'n'. Choice D, 'M = mol/dm³', is incorrect because 'dm³' is a volume unit equal to a liter, but the correct representation should be in terms of the volume of the solution in liters. Therefore, the correct answer is M = n/V.
4. How does kinetic energy change when the velocity of an object is doubled?
- A. Kinetic energy is halved
- B. Kinetic energy quadruples
- C. Kinetic energy doubles
- D. Kinetic energy remains the same
Correct answer: B
Rationale: Kinetic energy is directly proportional to the square of the velocity of an object according to the kinetic energy formula (KE = 0.5 * m * v^2). When the velocity is doubled, the kinetic energy increases by a factor of 2^2 = 4. Therefore, the kinetic energy quadruples when the velocity of an object is doubled. Choice A is incorrect because halving the kinetic energy would be the result if the velocity was halved, not doubled. Choice C is incorrect because doubling the velocity would result in a fourfold increase in kinetic energy, not just a double. Choice D is incorrect because kinetic energy is directly related to the velocity of an object, so if the velocity changes, the kinetic energy changes accordingly.
5. 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 the 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. The autonomic nervous system, sympathetic nervous system, and parasympathetic nervous system are not involved in voluntary muscle movements. Instead, they regulate involuntary functions of the body such as heart rate, digestion, and breathing. Therefore, choices B, C, and D are incorrect as they are not associated with voluntary muscle movements.
