1. On the study “effects of effective nurse-patient communication in decreasing anxiety of post operative patients†What is the Independent variable?
- A. Effective Nurse-patient communication
- B. Communication
- C. Decreasing Anxiety
- D. Post operative patient
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
2. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?
- A. Longer exposure leads to an increased risk of demineralization
- B. Longer exposure increases the opportunity for remineralization
- C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
- D. The critical pH at which enamel decalcification occurs is 5.5 or less
Correct answer: B
Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
3. How much extra protein (above RDA) is safe to consume?
- A. 2x your RDA
- B. any amount
- C. 3x your RDA
- D. 20 grams
Correct answer: A
Rationale: Consuming up to twice the Recommended Dietary Allowance (RDA) of protein is generally considered safe for most people, although it may vary depending on individual health conditions.
4. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?
- A. Zinc
- B. Iron
- C. Sodium
- D. Potassium
Correct answer: B
Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.
5. For a patient with celiac disease, which dietary modification is necessary?
- A. Increase protein intake
- B. Avoid gluten
- C. Increase dairy intake
- D. Avoid lactose
Correct answer: B
Rationale: The correct answer is B: Avoid gluten. Patients with celiac disease have an immune reaction to gluten, a protein found in wheat, barley, and rye. Therefore, it is crucial for individuals with celiac disease to avoid gluten-containing products. Increasing protein intake (Choice A) is not specifically necessary for celiac disease management. Increasing dairy intake (Choice C) is unrelated to the dietary requirements of individuals with celiac disease. Avoiding lactose (Choice D) is relevant for individuals with lactose intolerance, not celiac disease. Therefore, the only necessary modification for a patient with celiac disease is to avoid gluten.
