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 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: anorexia. In the early stage of hepatic inflammatory disorder, anorexia is the most likely symptom/sign. This is because hepatic inflammation can lead to a decrease in appetite, resulting in anorexia. Dark urine (A) is commonly associated with liver dysfunction but typically occurs later in the disease process. Occult blood in stools (B) is more indicative of gastrointestinal bleeding rather than early hepatic inflammation. Ascites (C) is the accumulation of fluid in the abdominal cavity and is a later manifestation of liver disease. Therefore, anorexia is the most likely symptom in the early stages of hepatic inflammatory disorder.

Correct Answer: C

Rationale: Objective data are measurable and observable facts obtained through physical examination or diagnostic tests. In this case, "Respirations 16" is a quantifiable and observable measurement, making it objective data. It is not influenced by personal interpretation or feelings. The other choices, such as "States 'doesn't feel good'", "Reports a headache", and "Nauseated" are subjective data because they are based on the patient's feelings or experiences, which can vary depending on individual perception and interpretation, making them less reliable for making clinical decisions. By focusing on objective data like "Respirations 16", the nurse can provide a more accurate assessment of the patient's condition.

Correct Answer: C

Rationale: The correct answer is C because the food pyramid suggests daily food choices based on the different food groups. It provides a visual guide on the proportions of each food group to consume for a balanced diet. It does not specify the exact number of servings (A), calculate calories (B), or divide food into four basic groups (D). The food pyramid is a tool to help individuals make healthier food choices by emphasizing variety and moderation.
