1. Where does carbohydrate digestion begin?
- A. Mouth
- B. Esophagus
- C. Stomach
- D. Small intestine
Correct answer: A
Rationale: Carbohydrate digestion begins in the mouth. The enzyme amylase, found in saliva, starts the process by breaking down starches into sugars. The esophagus is a passageway for food to reach the stomach and does not participate in digestion. The stomach mainly digests proteins and is not the primary site for carbohydrate breakdown. While the small intestine does play a crucial role in digesting carbohydrates, it is not where the process initiates. Therefore, the correct answer is the mouth.
2. A nurse in a prenatal clinic is educating a client about expected changes during pregnancy. The nurse should instruct the client about which change during pregnancy is related to the slowing of the gastrointestinal tract?
- A. Diarrhea
- B. Constipation
- C. Decreased absorption of iron
- D. Decreased absorption of calcium
Correct answer: B
Rationale: During pregnancy, the hormonal changes can lead to the slowing down of the gastrointestinal tract, causing constipation. This occurs due to increased progesterone levels, which relax smooth muscles, including those in the intestines, leading to slower bowel movements. Diarrhea is not typically associated with the slowing of the gastrointestinal tract during pregnancy. While there may be changes in the absorption of nutrients like iron and calcium, they are not directly related to the slowing of the gastrointestinal tract.
3. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:
- A. First degree burn C. Third degree burn
- B. Second degree burn D. Partial thickness burn
- C.
- D.
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.
4. In approximately what percentage of cases is the prevalence seen?
- A. Type 1 Diabetes
- B. Type 2 Diabetes
- C. N/A
- D. N/A
Correct answer: A
Rationale: The correct answer is A, Type 1 Diabetes. The prevalence of Type 1 Diabetes is seen in approximately 5% to 10% of cases. This statement highlights a key epidemiological characteristic of Type 1 Diabetes. Choice B, Type 2 Diabetes, is incorrect because the prevalence mentioned does not align with Type 2 Diabetes, which has a much higher prevalence in the general population. Choices C and D are not relevant to the question and can be disregarded.
5. What is a disadvantage of using a food frequency questionnaire?
- A. It does not influence the food choices of the consumer
- B. It is not affected by seasonal changes in the diet
- C. It is not effective for monitoring short-term changes in food intake
- D. It does not take too long to obtain the results
Correct answer: C
Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.
