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 person who consumes mostly pre-packaged meals is likely consuming too much ____.
- A. iron
- B. zinc
- C. sodium
- D. riboflavin
Correct answer: C
Rationale: Pre-packaged meals often contain high levels of sodium, which can contribute to hypertension and other health issues when consumed in excess.
3. Which condition is most closely associated with a high rate of gastroesophageal reflux disease?
- A. Pregnancy
- B. Anorexia
- C. Hypertension
- D. Diabetes mellitus
Correct answer: A
Rationale: Pregnancy is the correct answer as it is most closely associated with a high rate of gastroesophageal reflux disease (GERD). During pregnancy, the growing fetus exerts pressure on the stomach, leading to the backflow of stomach acid into the esophagus, causing GERD. This physiological change is a common occurrence in pregnant individuals. Conversely, anorexia, hypertension, and diabetes mellitus are not typically linked to a high rate of GERD. While these conditions have their own effects on the body, they do not directly contribute to the mechanisms that cause GERD, unlike the physical changes associated with pregnancy. Therefore, choices B, C, and D are incorrect.
4. The use of the Standards of Nursing Practice is important in the hospital. Which of the following statements best describes what it is?
- A. These are statements that describe the maximum or highest level of acceptable performance in nursing practice
- B. It refers to the scope of nursing practice as defined in Republic Act 9173
- C. It is a license issued by the Professional Regulation Commission to protect the public from substandard nursing
- D. The Standards of Care includes the various steps of the nursing process and the standards of professional
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
5. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?
- A. 5
- B. 5.5
- C. 6
- D. 6.5
Correct answer: B
Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.
