Nursing Elites

1. Which word is not spelled correctly in the context of the following sentence? The itinerant teacher moved continually from one school to another within the district.

• A. iterate
• B. continually
• C. within
• D. district

Correct answer: A

Rationale: The word 'iterate' is not spelled correctly in the sentence. The correct word that should be used here is 'itinerant,' which means constantly traveling from place to place, especially for work. In this context, 'iterate' does not fit as it means to repeat a process or utterance. 'Continually' is spelled correctly and means happening without interruption. 'Within' and 'district' are also spelled correctly and are used appropriately in the sentence. Therefore, choice A is the correct answer.

2. What are the three types of muscle tissue?

• A. Cardiac, spinal, stomach
• B. Smooth, skeletal, cardiac
• C. Neuron, epithelial, collagen
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Smooth, skeletal, cardiac. Smooth muscle is found in organs like the stomach and is involuntarily controlled. Skeletal muscle is found in voluntary muscles, like the bicep or quadriceps. Cardiac muscle is found only in the heart walls and works involuntarily to make the heart beat and pump blood. Choices A, C, and D are incorrect because they do not represent the three types of muscle tissue.

3. Find x. 120:x = 40:0.5.

• A. 60
• B. 0
• C. 1
• D. 25

Correct answer: C

Rationale: To find x, set up the proportion and solve for x: 120/x = 40/0.5. Cross multiply to get 120 * 0.5 = 40x. This simplifies to 60 = 40x. Divide by 40 to isolate x, giving x = 60/40 = 1. Therefore, the correct answer is C, which is 1. Choice A (60) is incorrect because it does not match the correct calculation. Choice B (0) is incorrect as the calculation results in x = 1, not 0. Choice D (25) is incorrect as it does not match the correct calculation of x = 1.

4. How many times more acidic is a substance with a pH of 3 compared to a substance with a pH of 5?

• A. 8
• B. 2
• C. 100
• D. 1,000

Correct answer: D

Rationale: The pH scale is logarithmic, indicating that each pH unit change reflects a 10-fold difference in acidity level. Going from pH 5 to pH 3 involves a difference of 2 units, which translates to a 100-fold increase in acidity level (10^2 = 100 for each unit). Therefore, a substance with a pH of 3 is 1,000 times more acidic than a substance with a pH of 5 (100 * 10 = 1,000). Choice A (8) is incorrect as it does not consider the logarithmic nature of the pH scale. Choice B (2) is incorrect because it represents the difference in pH units, not the increase in acidity level. Choice C (100) is incorrect as it miscalculates the increase in acidity level, which is 1,000 times and not 100 times.

5. The information presented in this article is?

• A. Against eating and drinking
• B. Against drinking alcohol
• C. Against eating rich foods
• D. Unbiased and informative.

Correct answer: D

Rationale: The information presented in the article is unbiased in its approach. While the article highlights the potential issues related to overeating and alcohol abuse, it does not explicitly advocate against eating and drinking, drinking alcohol, or eating rich foods. The primary focus is on the negative consequences of overeating and alcohol abuse, making choice D, 'Unbiased and informative,' the correct answer. Choices A, B, and C are incorrect as they are not supported by the content of the article; it merely discusses the risks associated with overeating and alcohol abuse without taking a stand against them.
