Metric Conversions for Nursing
1. What is the equivalent of 500 milliliters in liters?
- A. 0.05 liters
- B. 0.5 liters
- C. 5 liters
- D. 50 liters
Correct answer: B
Rationale: To convert milliliters to liters, you need to divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 500 milliliters divided by 1000 equals 0.5 liters. Choice A (0.05 liters) is incorrect because it represents 50 milliliters, not 500 milliliters. Choice C (5 liters) and Choice D (50 liters) are both incorrect as they are higher values and do not accurately represent the conversion of 500 milliliters to liters.
2. What is the result of multiplying 0.15 by 60?
- A. 9
- B. 15
- C. 45
- D. 60
Correct answer: A
Rationale: The correct answer is A: 9. To find the result of multiplying 0.15 by 60, you simply multiply the two numbers together. 0.15 * 60 = 9. This calculation involves basic multiplication. Choices B, C, and D are incorrect as they do not reflect the correct product of 0.15 and 60. Understanding how to multiply decimals and whole numbers is essential in various real-life scenarios such as calculating percentages or adjusting measurements.
3. Choose the most appropriate word to complete the sentence: 'He was _____ about his upcoming presentation.'
- A. apprehensive
- B. bored
- C. excited
- D. relieved
Correct answer: A
Rationale: The correct answer is 'apprehensive.' In the context of an upcoming presentation, being apprehensive implies a sense of worry or nervousness. This aligns well with the situation where one might feel uneasy or concerned about their upcoming presentation. The word 'bored' (choice B) is incorrect as it does not convey the right emotion for this context. 'Excited' (choice C) and 'relieved' (choice D) do not match the expected sentiment of worry or nervousness associated with an upcoming presentation, making them incorrect choices.
4. During ejaculation, sperm travels through a tube from the testes to the urethra. What is the name of this tube?
- A. Vas deferens
- B. Epididymis
- C. Seminal vesicle
- D. Urethra
Correct answer: A
Rationale: The vas deferens is the correct answer. It is the tube that carries sperm from the testes to the urethra during ejaculation. The vas deferens plays a crucial role in transporting mature sperm for ejaculation. The epididymis is responsible for sperm maturation and storage, not the direct passage of sperm to the urethra. The seminal vesicle produces fluid that combines with sperm to form semen but is not the tube for sperm transport. The urethra serves as the passageway for both urine and semen out of the body but is not the specific tube that transports sperm from the testes to the urethra.
5. What is the first thing the instructions say to do to get the young girl to sleep?
- A. Give her a stuffed animal.
- B. Read her a couple of books.
- C. Rock her in her chair.
- D. Play music in her room.
Correct answer: B
Rationale: The correct answer is B: 'Read her a couple of books.' The instructions in the extract clearly state that the first thing to do to get the young girl to sleep is to read her a couple of books. This helps her settle down for sleep. Choices A, C, and D are incorrect because giving her a stuffed animal, rocking her in her chair, or playing music in her room are mentioned in the instructions but not as the first step to get her to sleep.
