Nursing Elites

1. A client with pneumonia has arterial blood gases levels at: pH 7.33; PaCO2 49 mm/Hg; HCO3 25 mEq/L; PaO2 95. What intervention should the nurse implement based on these results?

• A. Institute coughing and deep breathing protocols.
• B. Administer oxygen via nasal cannula.
• C. Prepare for intubation and mechanical ventilation.
• D. Increase IV fluids to improve hydration.

Correct answer: A

Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.

2. A client with a history of hypertension is admitted with shortness of breath and chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Pulmonary function tests (PFTs)
• D. Arterial blood gases (ABGs)

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia in a client presenting with shortness of breath and chest pain. This test helps in evaluating the electrical activity of the heart and can identify signs of myocardial infarction or other cardiac issues. Choice B, Chest X-ray, may be ordered after the ECG to assess for pulmonary conditions like pneumonia or effusions. Choice C, Pulmonary function tests (PFTs), are used to evaluate lung function and are not the primary diagnostic tests for a client with symptoms of cardiac origin. Choice D, Arterial blood gases (ABGs), may provide information about oxygenation but are not the initial test indicated for a client with suspected cardiac issues.

3. In assessing a client 48 hours following a fracture, the nurse observes ecchymosis at the fracture site and recognizes that hematoma formation at the bone fragment site has occurred. What action should the nurse implement?

• A. Document the extent of the bruising in the medical record.
• B. Apply a cold compress to the area.
• C. Elevate the affected limb.
• D. Notify the healthcare provider.

Correct answer: A

Rationale: After observing ecchymosis at the fracture site, indicating hematoma formation, the nurse's priority is to document the extent of the bruising in the medical record. This documentation helps track the client's condition, aids in treatment planning, and serves as a baseline for monitoring changes. Applying a cold compress (choice B) may be contraindicated due to the risk of vasoconstriction and potential tissue damage. Elevating the affected limb (choice C) can be beneficial for reducing swelling in some cases, but documenting the bruising is the immediate concern. Notifying the healthcare provider (choice D) is not necessary at this stage unless there are other concerning symptoms or complications beyond the hematoma formation.

4. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Prothrombin time (PT)
• C. Serum sodium level
• D. Hemoglobin level of 12 g/dl

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.

5. In a client with liver cirrhosis admitted with ascites and jaundice, which laboratory value is most concerning to the nurse?

• A. Serum albumin of 3.0 g/dl
• B. Bilirubin of 3.0 mg/dl
• C. Ammonia level of 80 mcg/dl
• D. Prothrombin time of 18 seconds

Correct answer: C

Rationale: An elevated ammonia level of 80 mcg/dl is most concerning in a client with liver cirrhosis because it may indicate hepatic encephalopathy, a serious complication. Serum albumin, though low, is expected in cirrhosis and contributes to ascites. Bilirubin elevation is common in liver disease but may not be the most concerning in this case. Prothrombin time is typically prolonged in liver disease but may not be as acute as an elevated ammonia level suggesting hepatic encephalopathy.
