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. Which of the following ethical principles refers to the duty to do good?
- A. Beneficence
- B. Fidelity
- C. Veracity
- D. Nonmaleficence
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.
3. Where does most nutrient digestion and absorption occur?
- A. Large intestine
- B. Small intestine
- C. Stomach
- D. Mouth
Correct answer: B
Rationale: The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.
4. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.
- 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 true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.
5. A nurse is providing teaching to a group of adult athletes about preventing the effects of dehydration on the body. Which of the following manifestations should the nurse include in the teaching?
- A. Impaired motor control
- B. Drop in body temperature during exercise
- C. Increase in appetite
- D. Decreased resting heart rate
Correct answer: A
Rationale: Dehydration can lead to impaired motor control due to electrolyte imbalances affecting muscle function. Choices B, C, and D are incorrect. Dehydration typically causes an increase in body temperature during exercise, not a drop. Dehydration is more likely to suppress appetite, leading to a decrease rather than an increase in appetite. Also, dehydration often results in an increased heart rate rather than a decreased resting heart rate.
