Nursing Process Questions

Correct Answer: A

Rationale: Correct Answer: A: Respiratory acidosis Rationale: 1. Respiratory acidosis is caused by inadequate ventilation leading to increased PCO? and decreased pH. 2. Low pH indicates acidosis, and high PCO? indicates respiratory component. 3. Metabolic acidosis (B) results from non-respiratory causes. 4. Respiratory alkalosis (C) is characterized by high pH and low PCO?. 5. Metabolic alkalosis (D) is caused by non-respiratory factors with high pH.

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 nurse interprets this as respiratory alkalosis because the patient is likely experiencing hyperventilation, leading to a decrease in CO2 levels and respiratory alkalosis. This is indicated by an increase in pH and a decrease in PaCO2 on arterial blood gas analysis. Metabolic acidosis (choice B) is characterized by low pH and low bicarbonate levels, not seen in this scenario. Respiratory acidosis (choice A) is characterized by high PaCO2 levels and low pH, which is not the case here. Metabolic alkalosis (choice D) is characterized by high pH and high bicarbonate levels, which is not consistent with the patient's presentation.

Correct Answer: B

Rationale: The correct answer is B: Bence jones protein in the urine. In multiple myeloma, abnormal plasma cells produce excess monoclonal immunoglobulins, including Bence Jones proteins, which can be detected in the urine. This is a hallmark finding in multiple myeloma diagnosis. A: Incorrect. Serum creatinine levels are typically not affected in multiple myeloma. C: Incorrect. Hypercalcemia, not hypocalcemia, is commonly seen in multiple myeloma due to bone destruction. D: Incorrect. Multiple myeloma often presents with high serum protein levels, not low levels.

Correct Answer: A

Rationale: Step 1: Type A blood has been associated with a slightly higher risk of developing gastric cancer compared to other blood types. Step 2: The nurse mentioned a 10% increase in risk, which aligns with the increased risk associated with Type A blood. Step 3: Type AB and Type B blood do not have the same increased risk for gastric cancer as Type A blood. Step 4: Type O blood is actually associated with a lower risk of gastric cancer compared to Type A blood. Step 5: Therefore, the correct answer is A: Type A blood.
