Anatomy
1. What disease is characterized by progressive muscle weakness and wasting?
- A. Muscular dystrophy
- B. Myositis
- C. Fibromyalgia
- D. Carpal tunnel syndrome
Correct answer: A
Rationale: The correct answer is A: Muscular dystrophy. Muscular dystrophy is a genetic disorder characterized by progressive muscle weakness and wasting over time. It primarily affects skeletal muscles, leading to difficulties in movement and muscle function. Myositis is an inflammatory condition affecting the muscles, but it may not always result in progressive muscle weakness and wasting. Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal pain and fatigue, not necessarily progressive muscle weakness. Carpal tunnel syndrome is a compression neuropathy affecting the median nerve in the wrist, leading to symptoms like numbness and tingling in the hand, but it does not cause progressive muscle weakness and wasting like muscular dystrophy does.
2. A bar graph shows the number of patients admitted to the ER each day for a week. How do you determine the day with the highest number of admissions?
- A. Find the tallest bar in the graph.
- B. Compare the heights of all bars.
- C. Calculate the average number of admissions per day.
- D. Subtract the lowest number of admissions from the highest.
Correct answer: A
Rationale: The best approach is to find the tallest bar
3. What is the Pauli exclusion principle?
- A. The principle that electrons fill orbitals in order of increasing energy.
- B. The principle that electrons cannot be in the same orbital with the same spin.
- C. The principle that the maximum number of electrons in an orbital is 2n^2, where n is the energy level of the orbital.
- D. The principle that the attractive force between an electron and the nucleus is inversely proportional to the distance between them.
Correct answer: B
Rationale: The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. This means that electrons in the same orbital must have opposite spins, which is why they cannot be in the same orbital with the same spin. Option A refers to the Aufbau principle, option C refers to the maximum number of electrons in an orbital based on the formula 2n^2, and option D refers to Coulomb's law, which describes the electrostatic force between charged particles.
4. Which of the following is a characteristic of unsaturated fatty acids?
- A. They are solid at room temperature.
- B. They contain only single bonds.
- C. They have a higher melting point.
- D. They contain double or triple bonds.
Correct answer: D
Rationale: Unsaturated fatty acids contain double or triple bonds in their hydrocarbon chains. The other choices do not accurately describe unsaturated fatty acids.
5. Which of the following guidelines should be least considered in formulating objectives for
- A. Written nursing care plan
- B. Holistic approach
- C. Prescribed standards
- D. Staff preferences
Correct answer: D
Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.
6. Which additional information would be MOST relevant to the passage's argument?
- A. A detailed biography of a historical figure with no analysis of their impact on society.
- B. A timeline of technological advancements throughout history with no connection to social consequences.
- C. A case study of how historical knowledge informed the development of a successful solution to a contemporary problem.
- D. A statistical analysis of economic trends without any reference to historical events or context.
Correct answer: C
Rationale: Choice C aligns with the passage's theme by demonstrating how historical knowledge directly impacted a contemporary solution, further supporting the argument for history's value.
