1. What is the main function of the digestive system?

• A. To break down food and absorb nutrients
• B. To regulate body temperature
• C. To transport nutrients
• D. To produce hormones

Correct answer: A

Rationale: The main function of the digestive system is to break down food into nutrients through the process of digestion. Once the food is broken down, the nutrients are absorbed into the bloodstream and utilized by the body for various functions. Choice B, regulating body temperature, is incorrect as it is the function of the body's thermoregulatory system, not the digestive system. Choice C, transporting nutrients, is incorrect as the digestive system primarily focuses on breaking down and absorbing nutrients rather than transporting them. Choice D, producing hormones, is also incorrect as hormone production is mainly carried out by endocrine glands and not the digestive system.

2. What is the meaning of the word instill as used in the second paragraph of the passage?

• A. Impart
• B. Propagandize
• C. Demand
• D. Create

Correct answer: A

Rationale: The correct answer is A: 'Impart.' In the context of the passage, 'instill' means to impart important lessons about maintaining good health, staying fit, and keeping weight under control. This word choice is appropriate as it aligns with the idea of teaching and passing on knowledge. Choice B, 'Propagandize,' is incorrect as it implies spreading biased or misleading information, which is not the intended meaning in this context. Choice C, 'Demand,' is incorrect as it does not capture the concept of teaching or passing on lessons. Choice D, 'Create,' is also incorrect as it does not convey the idea of imparting knowledge or lessons, which is the central meaning of 'instill' in this context.

3. A nurse needs to dilute 2 milliliters of a concentrated medication with 8 milliliters of sterile water. What is the final concentration of the solution in percent?

• A. 16.67%
• B. 20%
• C. 25%
• D. 50%

Correct answer: B

Rationale: To find the final concentration, first, calculate the total volume of the solution (2 ml + 8 ml = 10 ml). Then, determine the concentration by dividing the volume of the concentrated medication by the total volume and multiplying by 100%: (2 ml / 10 ml) * 100% = 20%. Therefore, the correct answer is B. Choice A (16.67%) is incorrect as it does not represent the correct calculation. Choices C (25%) and D (50%) are both incorrect as they do not reflect the accurate concentration resulting from the dilution process.

4. A nurse works in a neonatal unit where infants' weights are measured in grams. What is the equivalent of 1,500 grams in pounds?

• A. 3.3 lbs
• B. 3.3 lbs
• C. 3.3 lbs
• D. 3.3 lbs

Correct answer: A

Rationale: To convert grams to pounds, you can use the conversion factor: 1 pound = 453.59237 grams. Therefore, to find the equivalent of 1,500 grams in pounds, divide 1,500 by 453.59237 to get approximately 3.3 pounds. Choice A is the correct answer because it accurately represents the conversion. Choices B, C, and D are duplicates and do not provide an alternative option.

5. The patient fractured the lateral portion of the hip bone, which is known as the _____.

• A. ilium
• B. ileum
• C. icterus
• D. ileus

Correct answer: A

Rationale: The correct answer is A, "ilium." The ilium is the lateral, or outer, portion of the hip bone. Choices B, C, and D are incorrect. Option B, "ileum," refers to a part of the small intestine. Option C, "icterus," is a term for jaundice, a condition related to the liver. Option D, "ileus," is a term for intestinal obstruction, which is unrelated to the hip bone.
