Correct Answer: D

Rationale: The Philippine Regulatory Commission - Board of Nursing (PRC-BON) has the power to regulate nursing practice in the Philippines.

Correct Answer: C

Rationale: Hypokalemia (low levels of potassium) increases the risk of digoxin toxicity. This is because digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in the cell membrane. When potassium levels are low, there is an increased binding of digoxin to these pumps, leading to enhanced entry of calcium into the cells. This can result in an increased intracellular calcium concentration, leading to digoxin toxicity and potential cardiac arrhythmias. Therefore, monitoring and correcting potassium levels is crucial in patients prescribed digoxin to reduce the risk of toxicity.

Correct Answer: B

Rationale: The ethical principle of autonomy emphasizes respecting the patient's right to make their own decisions regarding their treatment. In this scenario, the patient has the right to refuse treatment, and the nurse should respect that decision while also providing information and guidance to help the patient make informed choices. By upholding the principle of autonomy, the nurse can support the patient's decision-making process and work collaboratively with them to address any concerns or barriers to compliance with the treatment regimen. This approach honors the patient's right to self-determination and promotes a trusting relationship between the nurse and the patient.

Correct Answer: D

Rationale: Quantitative research is the type of research that involves collecting numerical data, which can be easily quantified and analyzed statistically. It is characterized by its structured methodology, objectivity, and the ability to control variables to a considerable extent. In the context of a study on sleep, where data related to sleep patterns, duration, quality, etc., need to be measured and analyzed in a systematic manner, quantitative research would be the most appropriate choice. This type of research allows for a more precise understanding of the relationships and patterns within the data, providing valuable insights into the sleep-related factors being studied.

Correct Answer: C

Rationale: In Participative Action Research (PAR), the core idea is to empower the community by involving them in the research process. By actively engaging community members in all stages of the research, they gain a sense of ownership and are empowered to take action based on the research findings. This approach ensures that the solutions generated are relevant, sustainable, and community-driven. Therefore, participation and engagement of the community is the step that will empower the community in PAR, unlike the other options where the focus is on external individuals or entities.
