1. 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.
2. Which dietary recommendation is most appropriate for a patient with gout?
- A. Increase protein intake
- B. Reduce carbohydrate intake
- C. Avoid purine-rich foods
- D. Increase calcium intake
Correct answer: C
Rationale: The most appropriate dietary recommendation for a patient with gout is to avoid purine-rich foods. Purine-rich foods such as red meat and shellfish can lead to increased uric acid levels in the body, triggering gout flare-ups. Increasing protein intake (Choice A) is not recommended as some high-protein foods are also high in purines. Reducing carbohydrate intake (Choice B) and increasing calcium intake (Choice D) are not directly related to managing gout symptoms.
3. Before Dianne performs the formal research study, what do you call the pre-testing, small-scale trial run to determine the effectiveness of data collection and methodological problems that might be encountered?
- A. Sampling
- B. Pre-testing
- C. Pre-Study
- D. Pilot Study
Correct answer: D
Rationale: The correct answer is 'Pilot Study.' A pilot study is a small-scale trial run conducted before the formal research study to identify and address any issues related to data collection and methodology. This helps in determining the effectiveness of the research process and identifying potential problems that may arise. Choice A, 'Sampling,' refers to the process of selecting a subset of individuals from a larger population for research. Choice B, 'Pre-testing,' simply involves testing something before the main testing phase. Choice C, 'Pre-Study,' is not a commonly used term in research methodology and does not specifically refer to the small-scale trial run described in the question.
4. Each statement is true of proteins, except one. Which is the exception?
- A. Proteins are composed of building blocks called amino acids
- B. The classification of the 20 common amino acids is based on the properties of their side chains
- C. The general structure of an amino acid varies considerably
- D. Amino acids polymerize to form long chains called polypeptides
Correct answer: B
Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.
5. Select all that apply. Which of the following are true about protein digestion?
- A. the end products of protein digestion are amino acids
- B. protein/polypeptides are digested in the large intestine by trypsin
- C. A, D
- D. protein/polypeptides are digested in the stomach by pepsin
Correct answer: C
Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.
