1. Calculate the product of the following decimals: (0.67)(0.09)

• A. 0.0603
• B. 0.6
• C. 0.603
• D. 0.06

Correct answer: A

Rationale: To multiply decimals, align the numbers as whole numbers, multiply as if they were whole numbers, then adjust the decimal point in the final answer. When multiplying 0.67 by 0.09, the result is 0.0603. To get this result, multiply 67 by 9 to get 603, then adjust the decimal point two places to the left in the final product, resulting in 0.0603. Choice B, 0.6, is incorrect because it does not account for the decimal precision in the multiplication. Choice C, 0.603, is incorrect as it has the digits reversed when compared to the correct answer. Choice D, 0.06, is incorrect as it does not reflect the correct product of the two decimals being multiplied.

2. Which of the following is an example of human error in an experiment?

• A. an imperfectly calibrated scale
• B. contaminating a sterile sample by breathing on it
• C. a draft in the laboratory slightly changing the temperature of a liquid
• D. failure to account for wind speed when measuring distance traveled

Correct answer: B

Rationale: Contaminating a sterile sample by breathing on it is an example of human error in an experiment because it involves an action directly caused by the researcher that compromises the integrity of the sample. Breathing on a sterile sample introduces external contaminants that can affect the results. Choices A, C, and D involve factors not directly under the researcher's control or are technical errors that do not involve direct human actions.

3. When an American Indian seeks help at the clinic for regulating her diabetes, the nurse can expect that she:

• A. will comply with the treatment prescribed.
• B. has not necessarily given up her beliefs in naturalistic causes of disease.
• C. may also be seeking the assistance of a shaman or medicine man.
• D. may need extra help in dealing with her illness and may be experiencing a crisis of faith.

Correct answer: C

Rationale: It is important to recognize that individuals from American Indian cultures may incorporate traditional healing practices, such as seeking the assistance of a shaman or medicine man, alongside biomedical treatments. This holistic approach to health and healing is a significant aspect of their cultural beliefs and practices. Choice A is incorrect because compliance with treatment may vary among individuals and cannot be generalized. Choice B is incorrect as it assumes that seeking traditional help means giving up beliefs in naturalistic causes of disease, which is not necessarily the case. Choice D is incorrect as it makes assumptions about the patient's emotional state and crisis of faith without evidence. Overall, understanding and respecting the integration of traditional healing practices is key to providing culturally sensitive care.

4. Which hormone is produced by the pineal gland?

• A. Corticosteroid
• B. Oxytocin
• C. Prolactin
• D. Melatonin

Correct answer: D

Rationale: Melatonin is the hormone produced by the pineal gland. It plays a crucial role in regulating the sleep-wake cycle and is instrumental in maintaining the body's circadian rhythm. Melatonin production is triggered by darkness and inhibited by light, aiding in signaling the body when it is time to sleep. Corticosteroid, oxytocin, and prolactin are hormones produced by other glands in the body and are not associated with the pineal gland. Therefore, they are incorrect choices for this question.

5. What is the result of subtracting 8.4 from 3.7?

• A. 4.5
• B. 4.8
• C. 4.6
• D. 4.7

Correct answer: D

Rationale: To find the result of subtracting 8.4 from 3.7, you need to subtract 3.7 from 8.4. Performing this subtraction, 8.4 - 3.7 equals 4.7. Therefore, the correct answer is 4.7. Choice A, 4.5, is incorrect as it is not the result of subtracting 8.4 from 3.7. Choices B and C, 4.8 and 4.6 respectively, are also incorrect as they do not match the correct subtraction result of 4.7.
