1. Which of the following most accurately describes the function of genes?
- A. They regulate the development of traits.
- B. They prevent foreign particles from entering the body.
- C. They work together with lutein to influence development.
- D. They transfer oxygen from the bloodstream to other parts of the body.
Correct answer: A
Rationale: The correct answer is A: 'They regulate the development of traits.' Genes play a crucial role in regulating the development of traits by encoding proteins that control various bodily functions and characteristics. This process involves gene expression and the production of proteins that ultimately determine an individual's traits. Choice B is incorrect because genes do not have a direct role in preventing foreign particles from entering the body; this function is primarily carried out by the immune system. Choice C is incorrect as genes do not specifically work with lutein to influence development; genes operate independently to regulate trait expression. Choice D is incorrect as genes are not responsible for transferring oxygen in the bloodstream; this function is carried out by red blood cells and hemoglobin.
2. The healthcare provider is reviewing the plan of care for a client with a newly placed colostomy. Which outcome would indicate effective client teaching?
- A. Client demonstrates how to irrigate the colostomy.
- B. Client verbalizes understanding of dietary changes.
- C. Client performs ostomy care independently.
- D. Client expresses feelings about the impact of the colostomy.
Correct answer: C
Rationale: The correct answer is C because effective teaching is demonstrated when the client can independently perform ostomy care. This indicates that the client has understood and retained the information provided during teaching. Choices A, B, and D are incorrect because demonstrating how to irrigate the colostomy, verbalizing understanding of dietary changes, and expressing feelings about the impact of the colostomy are important aspects of care but do not directly reflect the client's ability to apply the taught information in a practical setting.
3. As the new PHN in barangay Masinag, what is necessary to conduct in order to get a picture of the health and social status of the community?
- A. Mass information campaign
- B. Home visit
- C. Community assembly
- D. Community health survey
Correct answer: D
Rationale: To accurately assess the health and social status of a community, conducting a community health survey is essential. This method provides a comprehensive and systematic way to gather data on various health indicators and social determinants within the community. Choices A, B, and C are not as effective in providing a holistic view of the community's health and social status. A mass information campaign may raise awareness but lacks in-depth data collection, a home visit focuses on individual households rather than the entire community, and a community assembly may not reach all community members or provide structured data collection.
4. During an admission history, a client tells a nurse that she is under a lot of stress. Which of the following physiological responses should the nurse expect to increase as a result of stress?
- A. Blood glucose - a common stress response.
- B. Intestinal peristalsis - should decrease due to stress.
- C. Peripheral blood vessels diameter - can vary in response to stress.
- D. Urine output - may vary but not a typical stress response.
Correct answer: A
Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.
5. When attempting to establish risk reduction strategies in a community, the nurse notes that regional studies indicate a high number of persons with growth stunting and irreversible mental deficiencies caused by hypothyroidism (cretinism). The nurse should seek funding to implement which screening measure?
- A. T3 levels in school-aged children
- B. T4 levels in newborns
- C. TSH levels in women over 45
- D. Iodine levels in all persons over 60
Correct answer: B
Rationale: Screening T4 levels in newborns is crucial as it helps in the early detection of hypothyroidism, which can prevent conditions like cretinism. Checking T3 levels in school-aged children (Choice A) is not the most appropriate measure for early detection of hypothyroidism in newborns. Monitoring TSH levels in women over 45 (Choice C) is not directly related to detecting hypothyroidism in newborns. Additionally, monitoring iodine levels in all persons over 60 (Choice D) is not specifically aimed at early detection of hypothyroidism in newborns, which is crucial to prevent cretinism.
