A patient is experiencing shortness of breath. What is the nurse's immediate action?

Correct Answer: B

Rationale: Administering oxygen at 2 liters per minute via nasal cannula is the immediate action for a patient experiencing shortness of breath. This intervention helps to improve oxygenation and relieve respiratory distress promptly. Placing the patient in a high Fowler's position (choice A) may also be beneficial but providing oxygen takes precedence in this scenario to address the underlying hypoxemia. Encouraging deep breaths and coughing (choice C) may not be appropriate as the first action, especially without assessing the patient first. Assessing lung sounds (choice D) is essential but should follow the initial intervention of administering oxygen.

Correct Answer: A

Rationale: Administering insulin is the priority intervention for a patient admitted with high blood sugar levels because it helps lower the blood sugar levels effectively and rapidly. Insulin is a crucial medication for managing hyperglycemia in diabetes. Encouraging exercise (choice B) can be beneficial in the long term for managing blood sugar levels but is not the most immediate priority. While staying hydrated (choice C) is important, it is not the priority intervention when dealing with high blood sugar levels. Providing a low-sugar diet (choice D) is essential for long-term diabetes management but is not the immediate action needed to address high blood sugar levels in an admitted patient.

Correct Answer: D

Rationale: Corrected Rationale: When a patient is prescribed a diuretic for hypertension, monitoring the patient's sodium levels is crucial. Diuretics can lead to alterations in sodium levels, potentially causing complications like hyponatremia. While monitoring other parameters like respiratory rate, blood pressure, and potassium levels may also be important, the primary concern with diuretic therapy is the risk of sodium imbalance, making the monitoring of sodium levels the most critical assessment.

Correct Answer: B

Rationale: The correct answer is to assess the patient's oxygen saturation. In suspected pneumonia, ensuring adequate oxygenation is critical to monitor respiratory function. Auscultating lung sounds is important but assessing oxygen saturation takes precedence as it directly reflects the patient's oxygen levels. Monitoring white blood cell count is more related to infection assessment rather than immediate respiratory status. Checking skin integrity is essential for overall patient care but is not the priority in a patient with suspected pneumonia.

Correct Answer: D

Rationale: In a postoperative patient, an oxygen saturation level of 88% on room air indicates a significant drop below the normal range, suggesting potential respiratory distress. This finding requires immediate intervention by the nurse to ensure the patient receives adequate oxygenation. A heart rate of 88 beats per minute is within the normal range, making it a less concerning finding. A blood pressure of 130/80 mmHg falls within the normal range for blood pressure and does not require immediate intervention. Crackles heard in the lung bases may indicate fluid accumulation but may not always require immediate intervention unless accompanied by other concerning signs or symptoms.
