1. If a parent changes their baby 6 times a day, how many diapers will be needed in a year?
- A. 2190 diapers
- B. 2100 diapers
- C. 2160 diapers
- D. 2140 diapers
Correct answer: A
Rationale: To calculate the number of diapers needed in a year with 6 diaper changes per day, multiply the daily diaper changes (6) by the days in a year (365): 6 x 365 = 2190 diapers required. This calculation ensures an ample supply of diapers for maintaining the infant's hygiene and comfort. The other choices are incorrect because they do not accurately account for the number of diaper changes per day multiplied by the days in a year. Choice B (2100 diapers) is too low, while choices C (2160 diapers) and D (2140 diapers) are too high based on the calculation. Understanding the frequency and quantity of diaper changes is crucial for supporting the infant's health and well-being. Therefore, the correct answer is 2190 diapers.
2. What does the quoted word 'equilibrium' mean in the following sentence?
- A. Ability to speak
- B. Sense of taste
- C. Sense of balance
- D. Ability to swallow
Correct answer: C
Rationale: The correct answer is C: 'Sense of balance.' In the sentence provided, 'equilibrium' refers to a state of physical balance or stability. The client lost his balance when he woke up, indicating a loss of stability or equilibrium. Choices A, B, and D are incorrect because 'equilibrium' specifically refers to balance, not the ability to speak, sense of taste, or ability to swallow.
3. Which of the following words best completes the sentence? The meteorologist had forecast rain, ______ Sheila brought her umbrella to work.
- A. because
- B. yet
- C. so
- D. nor
Correct answer: A
Rationale: The word 'because' indicates the reason or cause for something. In this context, it logically connects the meteorologist's forecast of rain with Sheila bringing her umbrella to work. The conjunction 'because' explains the relationship between the rain forecast and Sheila's action of bringing an umbrella, making it the most suitable word for the sentence. Choices B, C, and D do not fit the context as they do not provide a logical reason for Sheila's action.
4. A patient who is lethargic may seem _______
- A. Energetic
- B. Exhausted
- C. Restless
- D. Hyperactive
Correct answer: B
Rationale: The correct answer is B: 'Exhausted.' Lethargic describes a state of feeling sluggish or lacking energy, which aligns with being exhausted. Choice A, 'Energetic,' is the opposite of lethargic. Choice C, 'Restless,' implies a different state of agitation than lethargy. Choice D, 'Hyperactive,' describes excessive activity, which contrasts with the lethargic state.
5. Which of the following is an organ of the respiratory system?
- A. Pancreas
- B. Brain
- C. Urethra
- D. Larynx
Correct answer: D
Rationale: The larynx is a vital organ of the respiratory system, responsible for producing sound and connecting the pharynx to the trachea. It plays a crucial role in breathing, swallowing, and vocalization. The brain, pancreas, and urethra are not part of the respiratory system; the brain is part of the nervous system, the pancreas is part of the digestive system, and the urethra is part of the urinary system. Therefore, the correct answer is the larynx.
