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. Which sign might a healthcare professional observe in a client with a high ammonia level?
- A. coma
- B. edema
- C. hypoxia
- D. polyuria
Correct answer: A
Rationale: A high ammonia level can lead to hepatic encephalopathy, which includes symptoms like confusion, disorientation, and can progress to coma. Coma is a severe condition of unconsciousness. Edema is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia is a condition of inadequate oxygen supply to tissues and organs, not directly related to high ammonia levels. Polyuria is excessive urination, which is not a typical sign of high ammonia levels.
3. As part of the teaching plan for a client with type I diabetes mellitus, the nurse should include that carbohydrate needs might increase when:
- A. an infection is present.
- B. there is an emotional upset.
- C. a large meal is eaten.
- D. active exercise is performed.
Correct answer: D
Rationale: During active exercise, insulin sensitivity increases, leading to lower blood glucose levels. To balance the effect of increased insulin sensitivity, additional carbohydrates might be needed. The other choices are incorrect because: A) an infection typically raises blood glucose levels rather than increasing the need for carbohydrates; B) emotional upset can impact blood glucose but does not directly affect carbohydrate needs; C) while a large meal can raise blood glucose levels, it does not necessarily mean an increase in carbohydrate needs.
4. What is a predisposing factor for cancer of the tongue?
- A. tobacco use
- B. obesity
- C. sun exposure
- D. eating sweets
Correct answer: A
Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.
5. A client is told that his test is positive, but in fact, the client does not have the disease tested for. Which type of false report is this an example of?
- A. positive
- B. false positive
- C. negative
- D. false negative
Correct answer: B
Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.
