Correct Answer: B

Rationale: The correct information about the nature of dengue fever that the nurse should relay to the community is that it could be deadly but preventable. Dengue fever is a viral infection spread by mosquitoes, particularly the Aedes aegypti mosquito. While many cases of dengue fever are mild, it can also lead to severe dengue, which can be life-threatening if not properly managed. However, preventive measures such as using mosquito repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes can significantly reduce the risk of contracting dengue fever. Therefore, it is important for the community to be aware that while dengue fever can be deadly, it is also preventable with appropriate measures.

Correct Answer: C

Rationale: The public health nurse's participation in the essential services that are relevant and accessible to the family and the community includes informing, educating, and empowering the people about health. This is a critical aspect of the role of a public health nurse as it involves engaging with individuals and communities to provide them with accurate information about health promotion, disease prevention, and access to healthcare services. By informing, educating, and empowering the people about health, public health nurses can help individuals and communities make informed decisions about their health and well-being, leading to improved health outcomes and overall community health.

Correct Answer: B

Rationale: Encouraging the patient to practice controlled coughing techniques would be the most appropriate intervention to address the symptoms of chronic cough and excessive sputum production in a patient with end-stage COPD receiving palliative care. Controlled coughing techniques can help the patient effectively clear respiratory secretions and improve airway clearance without the need for additional medications or interventions. This approach focuses on optimizing the patient's ability to manage their symptoms and maintain comfort, which aligns with the goals of palliative care. Administering bronchodilator medications, prescribing mucolytic medications, or referring the patient to a respiratory therapist for breathing exercises may have limited effectiveness in this advanced stage of the disease, and controlled coughing techniques would be a more practical and patient-centered approach to symptom management.

Correct Answer: A

Rationale: Illiterate clients may have difficulty understanding spoken or written information. Using symbols and images can help convey important messages and instructions in a visual way that can be easily understood without relying on literacy skills. This communication intervention is effective in ensuring that the client understands the information being provided, promoting better adherence to treatment plans and overall health outcomes.

Correct Answer: D

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.
