1. What is the most significant dietary influence on the development of dental caries?
- A. Carbohydrates
- B. Vitamins
- C. Minerals
- D. Fats
Correct answer: A
Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.
2. During which step of the nursing process does the nurse analyze data related to the patient's health status?
- A. Assessment
- B. Implementation
- C. Diagnosis
- D. Evaluation
Correct answer: A
Rationale: The correct answer is 'Assessment.' During the assessment phase of the nursing process, the nurse collects and analyzes data related to the patient's health status. This involves gathering information through various means such as patient interviews, physical examinations, and reviewing medical records. Choice B, 'Implementation,' refers to the phase where the nurse carries out the planned interventions. Choices C and D, 'Diagnosis' and 'Evaluation,' come after the assessment phase in the nursing process.
3. Which of the following has the greatest effect on an increase in body weight?
- A. Carbohydrate intake
- B. Protein intake
- C. Fat intake
- D. Total kilocalories
Correct answer: D
Rationale: Total kilocalories have the greatest effect on body weight as they represent the overall energy intake from all macronutrients combined. While the consumption of specific macronutrients like carbohydrates, proteins, and fats can affect weight management, the total calories consumed play the most significant role in determining body weight. Therefore, choices A, B, and C are incorrect as they focus on individual macronutrients rather than the overall energy balance provided by total kilocalories.
4. A nurse is initiating continuous enteral feedings for a client who has a new gastrostomy tube. Which of the following actions should the nurse take?
- A. Measure the client’s gastric residual every 12 hours.
- B. Obtain the client’s electrolyte levels every 4 hours.
- C. Keep the client’s head elevated at 15° during feedings.
- D. Flush the client’s tube with 30 mL of water every 4 hours.
Correct answer: D
Rationale: Flushing the client’s tube with 30 mL of water every 4 hours is essential to maintain tube patency and prevent blockages. This action helps ensure the continuous flow of enteral feedings without obstruction. Measuring the client’s gastric residual every 12 hours (Choice A) is important but not the priority when initiating enteral feedings. Obtaining the client’s electrolyte levels every 4 hours (Choice B) is unnecessary and not directly related to tube feeding initiation. Keeping the client’s head elevated at 15° during feedings (Choice C) is a good practice to prevent aspiration, but tube flushing is more crucial to prevent tube occlusion.
5. All of the following are instructions for proper foot care to be given to a client with peripheral vascular disease caused by diabetes. Which one is not?
- A. Trim nails using a nail clipper
- B. Apply cornstarch to the foot
- C. Always check the temperature of the water before bathing
- D. Use canvas shoes
Correct answer: A
Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.
