1. Which statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?
- A. ''This action of my lips helps to keep my airway open.''
- B. ''I can expel more air when I pucker up my lips to breathe out.''
- C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
- D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''
Correct answer: D
Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.
2. How many cc are there in 25 ounces?
- A. 250
- B. 500
- C. 750
- D. 1000
Correct answer: C
Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.
3. The supervising RN asks you to bring the unit's collected lab specimens to the lab 'stat'. You should ______________.
- A. not decline this task because nurses do not handle 'stats'.
- B. run this errand as promptly as possible
- C. run this errand immediately and without delay
- D. Complete this task before the end of your shift or after your lunch.
Correct answer: C
Rationale: In healthcare settings, 'stat' is commonly used to indicate that something should be done immediately and without any delay. It is a critical term used to prioritize urgent tasks. Nurses are responsible for various tasks, including handling urgent requests such as transporting lab specimens promptly. Option A is incorrect as nurses can handle urgent tasks like 'stats'. Option B is not as specific as option C, which clearly emphasizes the need for immediate action. Option D is incorrect as it suggests delaying the task until later, which goes against the urgency implied by the term 'stat'.
4. What is the primary purpose of emergency planning?
- A. Comply with the laws of the state.
- B. Comply with the laws of the U.S.
- C. Comply with both state and U.S. laws
- D. Maintain safety
Correct answer: D
Rationale: The primary purpose of emergency planning is to ensure and maintain the safety of people and the preservation of objects, such as buildings and personal possessions during emergencies or disasters. While compliance with state and federal laws regarding emergency planning is important, the main goal is to prioritize life and safety. Choices A, B, and C focus on legal compliance, which is necessary but secondary to the fundamental objective of safeguarding lives and property in emergency situations.
5. Which brain structure serves as the heat-regulating center?
- A. Hypothalamus
- B. Pituitary Gland
- C. Pons
- D. Medulla Oblongata
Correct answer: A
Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.
