1. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?
- A. Autonomic
- B. Sympathetic
- C. Parasympathetic
- D. Somatic
Correct answer: B
Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.
2. A nurse is caring for a client who has osteoarthritis. Which of the following findings should the nurse expect?
- A. Joint pain that improves with rest.
- B. Joint stiffness that improves with movement.
- C. Red, warm joints.
- D. Systemic inflammation.
Correct answer: A
Rationale: In osteoarthritis, joint pain that improves with rest is a common characteristic due to the relief obtained by reducing weight-bearing on the affected joint. Joint stiffness that improves with movement is more indicative of rheumatoid arthritis, not osteoarthritis. Red, warm joints are typically seen in inflammatory arthritis conditions like rheumatoid arthritis, while systemic inflammation is not a primary feature of osteoarthritis.
3. When examining heredity, mental disorders are almost always ________
- A. influenced by one particular gene.
- B. influenced by multiple genes.
- C. influenced by recessive genes.
- D. not influenced by genes.
Correct answer: B
Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.
4. A patient from the oncology unit asks the nurse about metastasis. Which of the following statements by the nurse requires immediate intervention by the head nurse?
- A. Metastasis is the replication of cells
- B. Metastasis can happen in most parts of the body
- C. The replication of cancer cells and travel from one area to another
- D. Metastasis is the spread of cancer cells
Correct answer: A
Rationale: The correct answer is A because metastasis refers to the spread of cancer cells to distant parts of the body, not the replication of cells. Choice B is correct as metastasis can indeed occur in various body parts. Choice C is incorrect as it inaccurately combines the concepts of replication and travel of cancer cells. Choice D is also correct as it accurately defines metastasis as the spread of cancer cells.
5. Which of the following processes does not help maintain the life of an individual organism?
- A. Responsiveness
- B. Movement
- C. Reproduction
- D. Respiration
Correct answer: C: Reproduction
Rationale: Reproduction is the correct answer because it is not essential for maintaining the life of an individual organism. While reproduction is crucial for the continuation of a species, it is not directly related to the survival or maintenance of an individual organism. Responsiveness allows an organism to react to stimuli, movement helps in obtaining resources and avoiding danger, and respiration provides the necessary energy for life processes. Therefore, reproduction is the process that does not directly contribute to maintaining the life of an individual organism.
