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 nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates because pneumonia causes inflammation and fluid accumulation in the alveoli, leading to impaired gas exchange. The nurse correctly identified the underlying respiratory issue. A: Ineffective breathing pattern related to pneumonia is incorrect as it focuses on the pattern of breathing rather than the physiological problem causing the breathing difficulty. B: Risk for infection related to chest x-ray procedure is incorrect as the patient already has a diagnosis of pneumonia, so the focus should be on managing the existing condition. C: Risk for deficient fluid volume related to dehydration is incorrect as there is no indication of dehydration in the question stem. In summary, the nurse's diagnosis of Impaired gas exchange related to alveolar-capillary membrane changes is the most appropriate as it addresses the respiratory issue caused by pneumonia and lower lobe infiltrates.

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: C

Rationale: The correct answer is C because respirations of 16 are measurable and quantifiable, making them objective data. Subjective data, like choices A, B, and D, are based on the patient's feelings or experiences and cannot be measured or observed directly. Choice A is subjective as it relies on the patient's self-report. Choice B is subjective as it describes a symptom reported by the patient. Choice D is subjective as it reflects the patient's feeling of nausea. Objective data is essential for making accurate clinical assessments and decisions.

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.
