Anatomy
1. Histamine, released during an allergic reaction, causes symptoms like:
- A. Fever and fatigue
- B. Runny nose and itchiness
- C. Muscle aches and joint pain
- D. Cough and shortness of breath
Correct answer: B
Rationale: The correct answer is B: 'Runny nose and itchiness.' Histamine is a chemical released by the body during an allergic reaction. It causes various symptoms such as itching, sneezing, runny nose, and watery eyes. These symptoms are commonly associated with allergic reactions like hay fever or hives. Fever and fatigue (option A) are not directly caused by histamine release. Muscle aches and joint pain (option C) are not typical symptoms of histamine release during an allergic reaction. Cough and shortness of breath (option D) are more commonly associated with asthma or respiratory allergies rather than histamine release.
2. The kidneys are bean-shaped organs that perform several vital functions. Which of the following is NOT a primary function of the kidneys?
- A. Filtering waste products from the blood
- B. Regulating blood pressure
- C. Producing red blood cells
- D. Maintaining water balance in the body
Correct answer: C
Rationale: The correct answer is C. While the kidneys perform multiple vital functions, such as filtering waste products from the blood, regulating blood pressure, and maintaining water balance in the body, they do not produce red blood cells. Red blood cell production occurs in the bone marrow, specifically in the spongy tissue called the red bone marrow. Therefore, the kidneys' primary functions do not include producing red blood cells.
3. Which of the following statements refers to criteria?
- A. Agreed on level of nursing care
- B. Characteristics used to measure the level of nursing care
- C. Step-by-step guidelines
- D. Statement which guide the group in decision making and problem solving
Correct answer: B
Rationale: Criteria are specific characteristics or standards used to evaluate or measure the quality or level of something. In this case, statement B, 'Characteristics used to measure the level of nursing care,' correctly refers to criteria because it highlights the specific attributes that are used to assess the quality or level of nursing care provided. The other options do not directly address the concept of criteria. Option A describes an agreed-upon level of care but does not specifically refer to criteria. Option C describes step-by-step guidelines, which are more related to processes or procedures. Option D mentions statements that guide decision-making and problem-solving, which are not necessarily criteria. Therefore, option B is the most appropriate choice as it directly aligns with the definition and concept of criteria.
4. What is the periodic law?
- A. The statement that the properties of the elements are a periodic function of their atomic numbers.
- B. The statement that the elements can be arranged in a table in which elements with similar properties are grouped together
- C. The statement that the elements can be arranged in a table in which the atomic number of an element is equal to the number of protons in its nucleus
- D. The statement that the elements can be arranged in a table in which the atomic mass of an element is equal to the number of neutrons in its nucleus.
Correct answer: A
Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.
5. What is the difference between a phylum and a class?
- A. Phylums are broader and more general
- B. Classes are broader and more general
- C. They are synonyms, used for the same groups
- D. Phylums are for plants, classes are for animals
Correct answer: A
Rationale: Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. Phylum is a broader category that includes multiple classes within it. Phylum represents a group of organisms sharing a common body plan or evolutionary history, while a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phylums are broader and more general compared to classes.
6. A book slides across a table. What determines the magnitude of the frictional force acting on the book?
- A. Only the mass of the book
- B. Only the normal force from the table
- C. Both the mass of the book and the normal force from the table
- D. Neither the mass of the book nor the normal force from the table
Correct answer: C
Rationale: Both the mass of the book and the normal force from the table. Friction is proportional to both the normal force and the coefficient of friction, which depends on the materials in contact. Since the normal force depends on the weight of the object (mass x gravity), both factors are important.
