Community Health HESI Study Guide
1. When asked to help develop interventions to combat obesity among children, the community health nurse should stress the importance of implementing which activity?
- A. Set goals that are focused on developing healthier lifestyles.
- B. Develop strict diet plans for school-aged children.
- C. Provide diet classes for obese children during school hours.
- D. Require all children to participate in organized team sports.
Correct answer: A
Rationale: The correct answer is A: Setting goals that are focused on developing healthier lifestyles. This approach is essential in combating childhood obesity as it promotes sustainable habits and behaviors. Option B, developing strict diet plans, may not be effective in the long term and could lead to unhealthy relationships with food. Option C, providing diet classes during school hours, may not address the root causes of obesity and could potentially stigmatize the children. Option D, requiring all children to participate in organized team sports, may not be feasible for all children and might not address dietary habits and sedentary behaviors.
2. A home health nurse is at the home of a client with diabetes and arthritis. The client has difficulty drawing up insulin. It would be most appropriate for the nurse to refer the client to:
- A. A social worker from the local hospital
- B. An occupational therapist from the community center
- C. A physical therapist from the rehabilitation agency
- D. Another client with diabetes mellitus who takes insulin
Correct answer: B
Rationale: An occupational therapist is the most appropriate professional to refer the client to in this situation. Occupational therapists can provide assistance with techniques and tools to help the client manage insulin administration despite arthritis. Referring the client to a social worker (Choice A) may not directly address the client's difficulty with insulin. While physical therapists (Choice C) focus on mobility and strength, they may not specialize in techniques for insulin administration. Referring the client to another client with diabetes (Choice D) is not a professional or appropriate solution to address the client's difficulty.
3. Which of the following statements is true of sickle-cell anemia?
- A. It is typically managed with treatments such as pain relief medications.
- B. It is caused by a mutation in the beta-globin gene.
- C. It leads to the obstruction of small blood vessels and decreased oxygen delivery.
- D. It is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent.
Correct answer: C
Rationale: The correct answer is C. Sickle-cell anemia results from a mutation in the beta-globin gene, causing red blood cells to become sickle-shaped. These misshapen cells can obstruct small blood vessels, leading to reduced oxygen delivery to tissues. Choices A, B, and D are incorrect because sickle-cell anemia is typically managed with treatments such as pain relief medications, hydration, and in severe cases, blood transfusions. It is caused by a specific mutation in the beta-globin gene, not by the inability to metabolize phenylalanine. Additionally, sickle-cell anemia is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent, not exclusive to any specific gender.
4. A client with AIDS has impaired gas exchange from a respiratory infection. Which assessment finding warrants immediate intervention by the nurse?
- A. Elevated temperature
- B. Generalized weakness
- C. Diminished lung sounds
- D. Pain when swallowing
Correct answer: D
Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.
5. 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.
