A nurse develops a nursing diagnostic statement for a patient with a medical diagnosis of pneumonia with chest x-ray results of lower lobe infiltrates. Which nursing diagnosis did the nurse write?

Correct Answer: D

Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This is the most appropriate nursing diagnosis for a patient with pneumonia and lower lobe infiltrates. The rationale is that pneumonia causes inflammation and fluid accumulation in the alveoli, impairing the exchange of oxygen and carbon dioxide in the lungs. This directly affects gas exchange. Choice A is incorrect because ineffective breathing pattern is a broad nursing diagnosis that does not specifically address the underlying issue of impaired gas exchange in pneumonia. Choice B is incorrect as the risk of infection related to the chest x-ray procedure is unrelated to the patient's current condition of pneumonia. Choice C is also incorrect as dehydration does not directly correlate with the patient's diagnosis of pneumonia and lower lobe infiltrates.

Correct Answer: D

Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates as it directly addresses the underlying physiological issue of impaired gas exchange due to alveolar-capillary membrane changes. The infiltrates indicate infection and inflammation in the lower lobes, leading to difficulty in oxygen and carbon dioxide exchange. This diagnosis aligns with the patient's medical condition and helps guide nursing interventions focused on improving oxygenation. Choice A is incorrect because ineffective breathing pattern is a broad diagnosis that does not specifically address the gas exchange issue seen in pneumonia. Choice B is incorrect as the risk for infection is already present with the diagnosis of pneumonia and does not directly address the patient's current respiratory status. Choice C is incorrect as dehydration is not the primary concern in a patient with pneumonia and lower lobe infiltrates.

Correct Answer: C

Rationale: The correct answer is C because respiratory rate is an observable and measurable data point, making it objective. Objective data is factual and observable, such as vital signs. Choices A, B, and D are subjective data as they rely on the patient's perception or interpretation, which can be influenced by various factors and may not always be accurate or reliable. In this case, the nurse can directly measure and document the patient's respiratory rate, making it an objective piece of information.

Correct Answer: D

Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates because pneumonia causes inflammation and fluid accumulation in the alveoli, impairing gas exchange. The nurse chose this diagnosis based on the patient's chest x-ray results indicating lower lobe infiltrates, which directly affect gas exchange. Choice A is incorrect because "ineffective breathing pattern" does not specifically address the underlying physiological issue of impaired gas exchange. Choice B is incorrect as it focuses on infection risk from the chest x-ray procedure, not the patient's medical condition. Choice C is incorrect as dehydration is not directly related to pneumonia and infiltrates.

Correct Answer: D

Rationale: Step 1: A goal should be measurable to track progress effectively. Step 2: The statement "a measurable change in a patient's physical state" indicates a specific and quantifiable outcome. Step 3: This aligns with the SMART criteria for goal setting - Specific, Measurable, Achievable, Relevant, Time-bound. Step 4: Other choices lack the specificity and measurability required for a clear goal. Step 5: Choice A talks about restriction, which is not directly related to understanding a goal. Step 6: Choice B focuses on negative responses, which is not necessarily indicative of understanding the goal. Step 7: Choice C is vague and lacks the specificity of a measurable outcome.
