Correct Answer: B

Rationale: The correct answer is B - Focus on the patient's presenting situation. This is because in the problem-oriented approach, the nurse must first gather data related to the patient's current issue or concern. This initial focus helps in identifying the primary problem, setting priorities, and developing a care plan. Now, let's analyze the other choices: A: Completing questions in chronological order may not be necessary or relevant to addressing the patient's immediate issue. C: Making accurate interpretations of the data comes after data collection, so it is not the first step. D: Conducting an observational overview is important but should come after focusing on the patient's presenting situation to gather specific and relevant data.

Correct Answer: B

Rationale: The correct answer is B: Focus on the patient's presenting situation. This is the first step in the problem-oriented approach as it helps the nurse understand the immediate issues and prioritize data collection. By focusing on the presenting situation, the nurse can gather relevant information efficiently. A: Completing questions in chronological order may not address the current problem effectively. C: Making accurate interpretations of the data comes after data collection, not as the first step. D: Conducting an observational overview is important but typically follows focusing on the presenting situation to guide what observations are necessary.

Correct Answer: B

Rationale: The correct answer is B because subjective data in a nursing assessment refers to information provided by the patient, such as feelings, perceptions, and symptoms. In this case, the client stating 'I feel nauseated' represents subjective data. This type of information cannot be measured or observed directly. A, C, and D are incorrect: A: Heart rate of 90 beats per minute is an objective measurement that can be directly observed. C: Blood pressure of 130/80 mmHg is also an objective measurement that can be directly observed. D: Skin appears flushed is an objective observation that can be directly seen.

Correct Answer: B

Rationale: Rationale for Correct Answer B: Rehabilitation plans for Mr. Gabatan should be considered and planned for early in his care to optimize his recovery and quality of life. Planning early allows for tailored interventions to address his specific needs and goals, promoting better outcomes. Early rehabilitation can also prevent complications and improve functional abilities. By proactively addressing rehabilitation needs, Mr. Gabatan can have a smoother transition back to his daily activities. Summary of Incorrect Choices: A: Leaving the rehabilitation plans solely up to Mr. Gabatan and his family may not consider all aspects of his recovery and could lead to suboptimal outcomes. C: Assuming that Mr. Gabatan will return to his former activities without a rehabilitation plan overlooks the individualized care needed for his recovery. D: Dismissing the need for rehabilitation based on the assumption that he may not be able to work again is premature and does not account for potential improvements in his condition through appropriate rehabilitation interventions.

Correct Answer: D

Rationale: The correct answer is D: To help nurses focus on the scope of medical practice. Developing a standard formal nursing diagnosis helps nurses to identify and focus on the patient's specific health issues within the nursing scope of practice. This enables nurses to provide targeted and effective care interventions. A: To form a language that can be encoded only by nurses - This choice is incorrect because the purpose of a nursing diagnosis is not exclusive to nurses and should be comprehensible to all healthcare professionals caring for the patient. B: To distinguish the nurse’s role from the physician’s role - While this distinction is important, the main purpose of developing a nursing diagnosis is to guide nursing interventions based on the patient's nursing care needs, rather than solely differentiating roles. C: To develop clinical judgment based on other’s intuition - This choice is incorrect as clinical judgment should be based on evidence-based practice and critical thinking, rather than solely relying on intuition or others' opinions.
