1. When the nurse is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should she measure?
- A. corner of the mouth to the tragus of the ear
- B. corner of the eye to the top of the ear
- C. tip of the chin to the sternum
- D. tip of the nose to the earlobe
Correct answer: B
Rationale: Correct! When sizing an oropharyngeal airway, the nurse should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to reach the pharynx without being too long or too short. Choices B, C, and D are incorrect as they do not provide the correct anatomical landmarks for determining the size of an oropharyngeal airway. Measuring from the corner of the mouth to the tragus of the ear is a standard method to ensure proper airway size and prevent complications during airway management.
2. When documenting in the client’s record, what type of information should be recorded?
- A. educated predictions of outcomes
- B. personal opinions
- C. objective information
- D. subjective information
Correct answer: C
Rationale: When documenting in a client's record, it is crucial to record objective information. Objective information is factual, based on observations and measurable data. This type of information is essential for accurate and effective communication among healthcare professionals involved in the client's care. Choices A and B, educated predictions of outcomes and personal opinions, are subjective in nature and may not provide an accurate representation of the client's condition. Choice D, subjective information, includes personal feelings, interpretations, and opinions, which are not ideal for documentation as they can be biased and unreliable.
3. How many feet should separate the nurse and the source when extinguishing a small, wastebasket fire with an appropriate extinguisher?
- A. 1 foot
- B. 2 feet
- C. 4 feet
- D. 6 feet
Correct answer: D
Rationale: The nurse should stand about 6 feet from the source of the fire. Getting closer might put the nurse in danger. Choice A, 1 foot, is incorrect because it is too close to the fire and can expose the nurse to unnecessary risk. Choice B, 2 feet, is also too close to the fire and may lead to potential harm. Similarly, choice C, 4 feet, is not the ideal distance as it is still within the range of potential danger. The correct answer is D, 6 feet, which is a safe distance for the nurse to extinguish the fire effectively without risking personal safety.
4. What should be the first action upon the discovery of an electrical fire?
- A. Disconnect the electrical power if it can be done safely
- B. Smother the source with an object like a blanket
- C. Saturate the source with water or another liquid
- D. Immediately activate the fire alarm
Correct answer: A
Rationale: The correct initial action upon discovering an electrical fire is to disconnect the electrical power if it can be done safely. This helps prevent the fire from spreading through the electrical system. Smothering the fire with a blanket is not recommended for electrical fires as it can fuel the fire. Saturating the source with water or other liquids is also not advised as it can lead to electric shock or spread the fire. Activating the fire alarm is important, but it should be done after disconnecting the power to prevent further escalation of the fire.
5. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
- A. serotonin
- B. cortisol
- C. alcohol
- D. narcotics
Correct answer: A
Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
