Anatomy
1. Tendonitis is an inflammation of the
- A. Muscles
- B. Tendons
- C. Ligaments
- D. Cartilage
Correct answer: B
Rationale: The correct answer is B: "Tendons." Tendonitis is a condition characterized by inflammation of the tendons, which are the tough bands of tissue that connect muscles to bones. This inflammation can result from overuse, injury, or aging. Muscles (Option A) are not typically inflamed in tendonitis, although they work in conjunction with tendons. Ligaments (Option C) connect bones to other bones and are not involved in tendonitis. Cartilage (Option D) is a smooth, flexible connective tissue that cushions joints and is not directly related to tendonitis.
2. One staff suggests that they review the pattern of nursing care that they are using, which is
- A. job description
- B. system used to deliver care
- C. manual of procedure
- D. rules to be followed
Correct answer: B
Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.
3. Which of the following is the smallest part of an element that can still be recognized as that element?
- A. Electron
- B. Proton
- C. Neutron
- D. Atom
Correct answer: D
Rationale: An atom is the smallest unit of matter that retains the chemical properties of an element. It is composed of a nucleus containing protons and neutrons, and electrons that orbit the nucleus. The number of protons in the nucleus determines the atomic number of the element, and the number of neutrons determines the isotope of the element.
4. Which division of the autonomic nervous system is responsible for the "rest and digest" response, promoting relaxation and conservation of energy?
- A. Sympathetic nervous system
- B. Parasympathetic nervous system
- C. Somatic nervous system
- D. Central nervous system
Correct answer: b
Rationale: The correct answer is B, the parasympathetic nervous system. This division of the autonomic nervous system is responsible for the "rest and digest" response, promoting relaxation and conservation of energy. When activated, it slows the heart rate, increases digestion, and helps the body rest and recover. The sympathetic nervous system, on the other hand, is responsible for the "fight or flight" response, preparing the body for action. The somatic nervous system controls voluntary movements, and the central nervous system consists of the brain and spinal cord, coordinating all nervous system functions.
5. The small intestine is where most of the chemical digestion and nutrient absorption occur. What is the finger-like projection in the small intestine that increases its surface area for absorption?
- A. Rugae
- B. Villi
- C. Microvilli
- D. All of the above
Correct answer: D
Rationale: The correct answer is D, 'All of the above.' The finger-like projection in the small intestine that increases its surface area for absorption is primarily the villi and microvilli. Villi are small, finger-like projections that line the inner wall of the small intestine, while microvilli are even smaller projections on the surface of the villi. Both structures significantly increase the surface area of the small intestine, allowing for more efficient absorption of nutrients. Rugae, on the other hand, are folds in the stomach lining that help with expansion when the stomach is full. Therefore, the rugae are not directly related to the increased surface area for absorption in the small intestine, making options A and B incorrect choices. Overall, options A, B, and C are all related to the structure of the small intestine but serve different functions, so the most appropriate answer is D, 'All of the above.'
6. What is a mutation?
- A. A change in the DNA sequence
- B. A type of protein
- C. A normal part of the DNA replication process
- D. A harmless variation in DNA
Correct answer: A
Rationale: Rationale: A mutation is defined as a change in the DNA sequence. Mutations can occur due to various factors such as errors during DNA replication, exposure to mutagens (e.g., chemicals, radiation), or spontaneous changes. These changes can result in alterations to the genetic information carried by an organism, which can have different effects ranging from harmless variations to causing genetic disorders or diseases. Mutations are a fundamental aspect of genetic diversity and evolution. Options B, C, and D do not accurately describe what a mutation is.
