1. A set of integers can be classified as positive, negative, or zero. Which of the following statements about multiplying positive and negative integers is ALWAYS true?

• A. The product will always be positive.
• B. The product will always be negative.
• C. The product will depend on the specific positive and negative numbers used.
• D. Positive and negative integers cannot be multiplied.

Correct answer: B

Rationale: When multiplying a positive integer by a negative integer, the product will always be negative. This is a fundamental rule of arithmetic. The sign of the product is determined by the rule that states a positive number multiplied by a negative number results in a negative number. Therefore, the statement that the product will always be negative is always true when multiplying positive and negative integers. Choice A is incorrect because the product is not always positive when multiplying positive and negative integers. Choice C is incorrect because the product is not dependent on the specific numbers but on the signs of the integers being multiplied. Choice D is incorrect as positive and negative integers can be multiplied.

2. According to the Clausius inequality, for a cyclic process involving heat transfer between a system and its surroundings at a single constant temperature (T), the following inequality must hold true:

• A. There is no relationship between heat transfer and temperature in a cyclic process.
• B. ∫ dQ/T ≥ 0
• C. ∫ Q/T = constant
• D. ∫ dQ/T ≤ 0

Correct answer: D

Rationale: The Clausius inequality states that for a cyclic process involving heat transfer at a single constant temperature, the integral of heat transfer divided by temperature (∫ dQ/T) must be less than or equal to zero. This inequality reflects the irreversibility of natural processes. Choice A is incorrect as there is a direct relationship between heat transfer and temperature in the Clausius inequality. Choice B is incorrect because the integral of dQ/T must be less than or equal to zero, not greater than or equal to zero. Choice C is incorrect because the integral of Q/T is not a constant in a cyclic process involving heat transfer at a single constant temperature.

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. Pulse, temperature, and respiration are known as ___________.

• A. vital signs
• B. vital statistics
• C. vital force
• D. vital capacity

Correct answer: A

Rationale: Pulse, temperature, and respiration are collectively known as vital signs. These measurements provide important information about a person's overall health status and are essential in assessing a person's well-being in various medical settings. Choice B, 'vital statistics,' is incorrect as vital statistics usually refer to data related to births, deaths, marriages, and health. Choice C, 'vital force,' is incorrect as it refers to a concept in some alternative medicine practices and is not a standard medical term for these measurements. Choice D, 'vital capacity,' is incorrect as it specifically refers to the maximum amount of air a person can expel from the lungs after a maximum inhalation, not a combination of pulse, temperature, and respiration.

5. Which of the following is not mentioned as a detail in the passage about Sickle-Cell Anemia?

• A. People of South American or African descent may be prone to sickle-cell anemia.
• B. Symptoms of sickle-cell anemia may include sudden occurrences of extreme abdominal and back pain.
• C. The red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes.
• D. Vitamin and mineral deficiencies may result in some anemia.

Correct answer: D

Rationale: The correct answer is D because the passage does not mention anything about vitamin and mineral deficiencies in relation to sickle-cell anemia. Choice A is incorrect as the passage specifies that sickle-cell anemia is more common among people of South American or African descent. Choice B is correct as the passage states that symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain. Choice C is correct as the passage describes that the red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes. The passage does not discuss any relationship between vitamin and mineral deficiencies and sickle-cell anemia, making choice D the correct option.
