1. What is a major constituent of cell membranes?
- A. cholesterol
- B. phospholipid
- C. saturated
- D. triglyceride
Correct answer: B
Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.
2. 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.
3. In responding to the care concerns of children with severe disease, referral to the hospital is of the essence especially if the child manifests which of the following?
- A. Wheezing
- B. Stop feeding well
- C. Fast breathing
- D. Difficulty to awaken
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
4. 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.
5. Does taste perception decline with age, and are individuals taking three or more medications likely to have less taste sensitivity, requiring greater amounts of sodium and sugar to perceive these tastes?
- 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: A
Rationale: Both statements are indeed true. As people age, their taste perception tends to decline. This change can be further exacerbated by the use of multiple medications, which can potentially dull taste sensitivity even more. Consequently, these individuals often need to consume foods with higher levels of sodium and sugar in order to perceive these tastes. Choices B, C, and D are incorrect because they deny either one or both of these established facts.
