1. Sucrose is a:
- A. monosaccharide
- B. disaccharide
- C. polysaccharide
- D. starch
Correct answer: B
Rationale: Sucrose is a disaccharide composed of one glucose and one fructose molecule.
2. Can soluble fibers be fermented by gut bacteria?
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: A
Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.
3. Through the client’s health history, you gather that Mr. Dizon smokes and drinks coffee. When taking the blood pressure of a client who recently smoked or drank coffee, how long should the nurse wait before taking the client’s blood pressure for accurate reading?
- A. 15 minutes
- B. 30 minutes
- C. 1 hour
- D. 5 minutes
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. 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. Which substance would most likely need to be restricted in patients with heart failure who use diuretics to help reduce fluid retention?
- A. potassium
- B. magnesium
- C. sodium
- D. chloride
Correct answer: C
Rationale: Sodium restriction is crucial in heart failure management to prevent fluid retention, which can worsen symptoms of heart failure.
