1. What is considered an acceptable LDL cholesterol level for children and adolescents?
- A. Less than 70 mg/dL
- B. Less than 110 mg/dL
- C. Less than 129 mg/dL
- D. Less than 170 mg/dL
Correct answer: B
Rationale: An LDL cholesterol level of less than 110 mg/dL is considered acceptable and healthy for children and adolescents. This level helps reduce the risk of cardiovascular diseases. Choices A, C, and D are incorrect because an LDL cholesterol level below 110 mg/dL is the recommended target for children and adolescents to maintain good heart health.
2. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:
- A. Set and turn on the alarm of the oximeter
- B. Do nothing since there is no identified problem
- C. Cover the fingertip sensor with a towel or bedsheet
- D. Change the location of the sensor every four hours
Correct answer: B
Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.
3. Which physiologic role does vitamin C play in the body?
- A. Transcribing DNA to RNA
- B. Absorption and regulation of calcium
- C. Protects integrity of cellular membranes
- D. Catalyst for synthesis of blood-clotting factors
Correct answer: C
Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.
4. A nurse at a provider's office is providing teaching to a client who is taking chemotherapy and losing weight. Which of the following should the nurse recommend to increase calorie and protein intake? (Select one that does not apply.)
- A. Top yogurt with fruits.
- B. Add cream to soups.
- C. Use milk instead of water in recipes.
- D. Increase fluids during meals.
Correct answer: D
Rationale: The correct recommendation to increase calorie and protein intake for a client taking chemotherapy and losing weight is to add cream to soups (choice B), as it provides additional calories and proteins. Using milk instead of water in recipes (choice C) can also increase the calorie and protein content. Topping yogurt with fruits (choice A) can be a healthy choice but may not significantly increase calorie and protein intake. Increasing fluids during meals (choice D) may fill up the stomach, potentially reducing the intake of solid foods, which is not ideal when trying to increase calorie and protein consumption.
5. As the head nurse in the OR, how can you improve the effectiveness of clinical alarm systems?
- A. Limit suppliers to a few so that quality is maintained
- B. Implement a regular inventory of supplies and equipment
- C. Adherence to manufacturer’s recommendation
- D. Implement a regular maintenance and testing of alarm systems
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
