Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A client with a mediastinal chest tube is being assessed by a nurse. Which symptoms require the nurse's immediate intervention? (SATA)

• A. Production of pink sputum
• B. Tracheal deviation
• C. Pain at insertion site
• D. Sudden onset of shortness of breath

Correct answer: B

Rationale: Immediate intervention is necessary when a client with a mediastinal chest tube exhibits tracheal deviation since it may indicate a tension pneumothorax. This condition requires prompt attention to prevent serious complications. While the production of pink sputum and pain at the insertion site should be monitored and reported, they do not typically require immediate intervention. Sudden onset of shortness of breath could indicate various issues related to the chest tube but is not as critical as tracheal deviation in this context.

3. A client with a spinal cord injury at T6 suddenly reports a pounding headache and blurred vision. What action should the nurse take first?

• A. Administer pain medication as ordered.
• B. Check the client's blood pressure.
• C. Place the client in a supine position.
• D. Increase the client's fluid intake.

Correct answer: B

Rationale: The client's symptoms of a pounding headache and blurred vision are indicative of autonomic dysreflexia, a potentially life-threatening condition in clients with spinal cord injuries at T6 or above. The nurse's priority action should be to check the client's blood pressure as autonomic dysreflexia can lead to severe hypertension. Identifying and addressing this elevated blood pressure promptly is crucial to prevent serious complications such as seizures, stroke, or even death. Once the blood pressure is assessed and managed, further interventions can be implemented to address the underlying cause of autonomic dysreflexia.

4. A client is going to be admitted for a scheduled surgical procedure. Which action does the nurse explain is the most important thing the client can do to protect against errors?

• A. Bring a list of all medications and their purposes.
• B. Keep the doctor's phone number close by.
• C. Ensure all providers wash their hands before entering the room.
• D. Document the name of each caregiver who enters the room.

Correct answer: A

Rationale: The most important action a client can take to protect against errors is to bring a list of all medications and their purposes. This helps ensure that the healthcare team has accurate information about the client's medications, reducing the risk of medication errors, which are the most common type of healthcare mistake. Knowing the medications and their purposes can also aid in preventing drug interactions and adverse effects during the surgical procedure.

5. A client presents with shortness of breath, pain in the lung area, and a recent history of starting birth control pills and smoking. Vital signs include a heart rate of 110/min, respiratory rate of 40/min, and blood pressure of 140/80 mm Hg. Arterial blood gases reveal pH 7.50, PaCO2 29 mm Hg, PaO2 60 mm Hg, HCO3 20 mEq/L, and SaO2 86%. What is the priority nursing intervention?

• A. Prepare for mechanical ventilation.
• B. Administer oxygen via face mask.
• C. Prepare to administer a sedative.
• D. Assess for indications of pulmonary embolism.

Correct answer: B

Rationale: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.
