1. What is the first step in the scientific method?
- A. Conduct an experiment
- B. Make an observation and ask a question
- C. Formulate a hypothesis
- D. Reach a consensus
Correct answer: B
Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.
2. A patient with an ileostomy is suffering from frequent diarrhea. The clinician should advise the patient to increase his intake of what food to thicken stool output?
- A. celery
- B. salad greens
- C. potatoes
- D. dried beans and peas
Correct answer: C
Rationale: Potatoes are starchy and can help thicken stool output, making them beneficial for patients with an ileostomy experiencing diarrhea.
3. Nonnutritive sweeteners are not metabolized by microorganisms and do not promote dental caries. Products made with a nonnutritive sweetener can be used as frequently as 8 to 10 times per day.
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: C
Rationale: The first statement is true; nonnutritive sweeteners do not promote caries. However, the second statement is false because products with nonnutritive sweeteners should still be consumed in moderation.
4. A patient is on a low-sodium diet. Which food item should the patient avoid?
- A. Fresh fruit
- B. Canned soup
- C. Whole grain bread
- D. Grilled chicken
Correct answer: B
Rationale: The correct answer is B: Canned soup. Canned soup is commonly high in sodium content, which is not suitable for a patient on a low-sodium diet. Fresh fruit, whole grain bread, and grilled chicken typically have lower sodium levels and can be included in a low-sodium diet. Therefore, the patient should avoid canned soup to adhere to the requirements of a low-sodium diet.
5. In PEM, which condition is characterized by symptoms such as muscle weakness, hanging skin, delayed tooth eruption, and changes in saliva?
- A. Marasmus
- B. Kwashiorkor
- C. Anemia
- D. Noma
Correct answer: A
Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.
