When using electronic (or computerized) documentation, which process should the nurse use to ensure that no one alters the information the nurse has entered?

Choice A rationale

Impaired gas exchange directly affects the patient's oxygenation and carbon dioxide elimination, which are fundamental physiological needs. Alveolar inflammation and infection in pneumonia disrupt the normal diffusion of gases in the lungs, potentially leading to hypoxemia and hypercapnia, posing an immediate threat to life if not addressed promptly. Normal partial pressure of oxygen (PaO₂) is 80-100 mmHg, and normal partial pressure of carbon dioxide (PaCO₂) is 35-45 mmHg.

Choice B rationale

Pruritus, or itching, while uncomfortable, is a symptom related to medication side effects and does not directly compromise vital physiological functions like gas exchange. Addressing the underlying cause and providing symptomatic relief are important but are a lower priority than ensuring adequate oxygenation.

Choice C rationale

Knowledge deficit regarding risk factors for pneumonia is important for long-term health management and prevention of future episodes. However, in the acute phase of pneumonia, the immediate physiological compromise of impaired gas exchange takes precedence over addressing knowledge gaps.

Choice D rationale

Activity intolerance due to fatigue and shortness of breath is a consequence of the physiological changes associated with pneumonia, primarily the impaired gas exchange. While it affects the patient's quality of life, it is a manifestation of the primary problem rather than the most immediate threat to physiological stability.

Choice A rationale

"The patient has a fractured right tibia with a cast that was applied 2 days ago" provides the Background, giving relevant history about the patient's current condition. "The nurse requests that the primary health provider examine the patient" is the Recommendation, suggesting a course of action based on the assessment. "The patient reported his pain as a 7 on a 0-10 pain scale 1 hour after he received Norco 10mg PO" describes the Situation, highlighting the current problem or change in condition. "The patient's toes are cool and pale, and the patient reports that the foot feels numb" is the Assessment, presenting the nurse's findings and interpretation of the patient's status.

Choice B rationale

This option incorrectly assigns the documentation entries to the SBAR components. The fractured tibia and cast history are background, not the immediate situation. The pain report after medication is the situation, not background. The recommendation is correctly identified, but the cool, pale, numb toes are the assessment, not the recommendation.

Choice C rationale

This option misidentifies the components. The cool, pale, numb toes are assessment findings, not the situation. The pain report after medication is the situation, not background. The fractured tibia and cast history are background, not the assessment. The request for provider examination is the recommendation.

Choice D rationale

This option incorrectly orders the SBAR components. The request for provider examination is the recommendation, not the situation. The cool, pale, numb toes are the assessment, not the background. The pain report after medication is the situation. The fractured tibia and cast history are background. .
