1. Which gland produces hormones that regulate metabolism?

A. Pituitary gland
B. Thyroid gland
C. Adrenal gland
D. Pineal gland

Correct answer: B

Rationale: The thyroid gland is responsible for producing hormones, such as thyroxine, that play a crucial role in regulating metabolism, energy production, and overall growth and development in the body. The pituitary gland, while important for hormone regulation, does not primarily regulate metabolism. The adrenal gland is responsible for producing hormones like cortisol and adrenaline, which are more related to stress response than direct metabolism regulation. The pineal gland mainly produces melatonin, which regulates sleep-wake cycles and not metabolism. Therefore, the correct answer is the thyroid gland.

2. Identify the type of reaction shown: 8Fe + S → 8FeS

A. Single displacement
B. Double displacement
C. Synthesis
D. Acid-base

Correct answer: C

Rationale: The reaction shown (8Fe + S → 8FeS) is a synthesis reaction. In a synthesis reaction, two or more substances combine to form a single compound. In this case, iron (Fe) and sulfur (S) combine to form iron sulfide (FeS). The key characteristic of a synthesis reaction is the formation of a single product from multiple reactants, which aligns with the given chemical equation. Choice A, single displacement, involves an element displacing another in a compound, which is not the case here. Choice B, double displacement, involves the exchange of ions between two compounds, which is also not happening in this reaction. Choice D, acid-base, refers to reactions between an acid and a base to form salt and water, which is not the case in the given equation.

3. 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.

4. What does the word Trepidation mean?

A. Fear
B. Misgivings
C. Confidence
D. Doubt

Correct answer: B

Rationale: The correct answer is B: 'Misgivings'. Trepidation is defined as a feeling of fear or anxiety about something that may happen. Choice A ('Fear') is too broad and does not capture the specific sense of unease that trepidation conveys. Choice C ('Confidence') is the opposite of what trepidation represents. Choice D ('Doubt') is related to uncertainty but does not fully encapsulate the sense of fear and anxiety associated with trepidation.

5. What is 70% of 110?

A. 77
B. 79
C. 81
D. 83

Correct answer: C

Rationale: To find 70% of 110, you need to multiply 110 by 0.7. Therefore, 110 * 0.7 = 77. The correct answer is 81, not 77. Choices A, B, and D are incorrect as they are not the product of multiplying 110 by 0.7, which is the correct method for finding 70% of 110.
