1. Select the correct word for the blank in the following sentence: Nurse Junko and ________ will review the patient’s chart.
- A. me
- B. she
- C. them
- D. him
Correct answer: B
Rationale: In this sentence, the correct word to use after 'and' is a pronoun that would refer to Nurse Junko as another person. Since 'Nurse Junko' is a singular female subject, the appropriate pronoun to use is 'she.' Therefore, the correct choice is 'she.' Choice 'A' ('me') is incorrect because it is an object pronoun, not a subject pronoun. Choice 'C' ('them') is incorrect because it is a plural pronoun and does not agree with the singular subject 'Nurse Junko.' Choice 'D' ('him') is incorrect because it is a masculine pronoun, while the subject 'Nurse Junko' is a singular female, so the pronoun should be feminine.
2. A paroxysm is a sudden spasm. Another word for this might be ___________.
- A. convulsion
- B. symptom
- C. efficacy
- D. embolism
Correct answer: A
Rationale: The correct answer is A: "convulsion." A paroxysm is defined as a sudden spasm or convulsion. The word "convulsion" specifically refers to a violent and involuntary contraction or spasm of muscles, which aligns perfectly with the description of a paroxysm. On the other hand, choices B, C, and D are incorrect. "Symptom" (B) refers to a manifestation of a condition rather than a physical spasm. "Efficacy" (C) relates to effectiveness or success, not a sudden spasm. "Embolism" (D) refers to the obstruction of a blood vessel, which is unrelated to the concept of a sudden spasm. Therefore, convulsion is the most suitable synonym for a paroxysm in this context.
3. What propels the cell forward?
- A. Microfilaments
- B. Propulsion
- C. Cilia
- D. Flagella
Correct answer: B
Rationale: Propulsion, not microfilaments, cilia, or flagella, is what drives the cell forward. Propulsion is the force or process that propels the cell forward and allows it to move within its environment. Microfilaments are involved in cell structure, cilia are small hair-like structures for movement, and flagella are tail-like structures used for cell propulsion in some organisms.
4. What is the best description for the term flaccid?
- A. Light-colored
- B. Drooping or loose
- C. Uncontaminated
- D. Unusually aggressive
Correct answer: B
Rationale: The term 'flaccid' is commonly used to describe something that is limp, soft, or lacking firmness. It suggests a lack of stiffness or rigidity, often used to describe plants, muscles, or other objects that are in a drooping or loose state. Choice A 'Light-colored' is incorrect as it does not convey the meaning of flaccid. Choice C 'Uncontaminated' and Choice D 'Unusually aggressive' are also incorrect as they do not relate to the definition of flaccid.
5. A 110-volt appliance draws 0 amperes. How many watts of power does it require?
- A. 0 watts
- B. 108 watts
- C. 112 watts
- D. 220 watts
Correct answer: A
Rationale: When a 110-volt appliance draws 0 amperes, it means that the power consumption is zero as well. The formula to calculate power is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amperes. Since the current is 0 amperes, the power required by the appliance is also 0 watts. Therefore, the correct answer is 0 watts. Choice B, 108 watts, is incorrect because there is no current drawn. Choice C, 112 watts, and choice D, 220 watts, are incorrect as well since the appliance is not consuming any power when drawing 0 amperes.
