1. Which of the following statements best describes substance P?
- A. Substance P decreases a client's sensitivity to pain
- B. Substance P levels are drawn before administration of narcotic analgesics
- C. Substance P is found in the brain and is responsible for pain control and management of depression
- D. Substance P is found in the dorsal horn of the spinal column
Correct answer: D
Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
2. Which principle of body mechanics may help to reduce the risk of a back injury?
- A. Maintain a wide base of support
- B. Bend from the knees, not the waist
- C. Keep the back straight while lifting
- D. Push or pull objects rather than lifting
Correct answer: C
Rationale: Proper body mechanics are crucial to prevent injuries, especially for professions involving lifting and moving objects. Keeping the back straight while lifting is essential to reduce the risk of back injuries as it helps maintain the spine's natural alignment and prevents excessive strain on the back muscles. Choosing choices A, B, and D would increase the risk of back injury. Maintaining a wide base of support provides stability, bending from the knees instead of the waist protects the lower back, and pushing or pulling objects reduces the strain on the back muscles, all contributing to preventing back injuries.
3. Which of the following descriptors is most appropriate to use when stating the 'problem' part of a nursing diagnosis?
- A. Grimacing
- B. Anxiety
- C. Oxygenation saturation 93%
- D. Output 500 mL in 8 hours
Correct answer: B
Rationale: The problem part of a nursing diagnosis in the context of nursing care plans should focus on the client's response to a life process, event, or stressor. This response is what is used to identify the nursing diagnosis. 'Anxiety' is the most appropriate descriptor for the problem part of a nursing diagnosis as it reflects a psychological response that can be addressed by nursing interventions. 'Grimacing' is a physical manifestation and not the problem itself. 'Oxygenation saturation 93%' and 'Output 500 mL in 8 hours' are data points or cues that a nurse would use to formulate the nursing diagnostic statement, not the actual problem being addressed.
4. Which of the following actions can help prevent a fire in the area where a healthcare professional works?
- A. Using an adaptor when plugging in client equipment
- B. Marking equipment that is not working properly and using it carefully until it can be inspected by maintenance
- C. Notifying visitors or posting signs that indicate oxygen is in use in certain areas
- D. Keeping extra equipment stored in one area with other supplies and materials
Correct answer: C
Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.
5. Which nursing intervention is the highest priority for a client at risk for falls in a hospital setting?
- A. Keep all of the side rails up
- B. Review prescribed medications
- C. Complete the "get up and go"? test
- D. Place the bed in the lowest position
Correct answer: D
Rationale: The highest priority nursing intervention for a client at risk for falls in a hospital setting is to place the bed in the lowest position. This action ensures that the client falls the shortest distance, reducing the risk of injury. Keeping all side rails up (Option A) may lead to a fall with injury, as the client might attempt to get over the rail and fall from a higher distance. Reviewing prescribed medications (Option B) is important as certain medications can increase the risk of falling, but it is not the best answer as it is not applicable to all clients. Completing the "get up and go"? test (Option C) can help assess a client's risk for falling but does not directly prevent injury.
