1. What was the author's primary purpose for writing this essay?

A. To inform the reader about the stages of the water cycle
B. To explain how rain is formed
C. To persuade readers to preserve water
D. To inform the reader about water's importance in life

Correct answer: A

Rationale: The author's primary purpose for writing this essay is to inform the readers about the stages of the water cycle. The essay explains how water moves through the cycle, including processes like precipitation, runoff, evaporation, and condensation. Choice A is correct because the focus is on educating readers about the water cycle, not just explaining how rain is formed (Choice B), persuading readers to preserve water (Choice C), or discussing water's importance in life (Choice D). The detailed explanation of the water cycle provided in the extract supports the correct answer.

2. Prokaryotic cells:

A. Have a nucleus
B. Have a capsule
C. Have membrane-bound organelles
D. Cannot move on their own

Correct answer: B

Rationale: Prokaryotic cells do not have a nucleus or membrane-bound organelles. One characteristic feature of prokaryotic cells is the presence of a capsule, which is a protective layer outside the cell wall. This capsule helps the prokaryotic cell adhere to surfaces, evade the host immune system, and protect against desiccation. Choice A is incorrect because prokaryotic cells lack a nucleus. Choice C is incorrect as prokaryotic cells do not have membrane-bound organelles. Choice D is incorrect as prokaryotic cells can move using structures like flagella or pili.

3. Which vitamin is essential for the synthesis of collagen?

A. Vitamin C
B. Vitamin D
C. Vitamin B12
D. Vitamin K

Correct answer: A

Rationale: The correct answer is Vitamin C. Vitamin C is essential for the synthesis of collagen, a protein crucial for maintaining the structure and integrity of skin, blood vessels, and bones. It plays a key role in the hydroxylation of proline and lysine residues in collagen synthesis, which is necessary for the stability and strength of collagen fibers. Choice B: Vitamin D is essential for bone health and calcium absorption but is not directly involved in collagen synthesis. Choice C: Vitamin B12 is important for red blood cell formation and neurological function but is not directly related to collagen synthesis. Choice D: Vitamin K is necessary for blood clotting and bone metabolism but does not play a direct role in collagen synthesis.

4. An elderly Mexican-American woman with traditional beliefs has been admitted to an inpatient care unit. A culturally-sensitive nurse would:

A. contact the hospital administrator about the best course of action.
B. automatically get a curandero for her because it is not culturally appropriate for her to request one.
C. further assess the patient's cultural beliefs and offer the patient assistance in contacting a curandero or priest if she desires.
D. ask the family what they would like to do because Mexican-Americans traditionally give control of decisions to their families.

Correct answer: C

Rationale: When caring for a patient with traditional beliefs, especially one belonging to a culture like Mexican-American where folk or religious healers are important, a culturally-sensitive nurse should assess the patient's beliefs and preferences. By offering assistance in contacting a curandero or priest, the nurse acknowledges and respects the patient's cultural practices and provides holistic care that aligns with the patient's values. This approach helps build trust and ensures the patient receives care that is culturally appropriate and respectful. Choice A is incorrect as contacting the hospital administrator may not directly address the patient's cultural needs. Choice B is inappropriate as assuming the patient needs a curandero without assessment disregards individual preferences. Choice D is incorrect because while family involvement is valued in Mexican-American culture, the primary focus should be on the patient's individual preferences and autonomy.

5. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'

A. Add water to
B. Reduce by half
C. Warm up
D. Decontaminate

Correct answer: A

Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.
