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 is 1-day postoperative following a left lower lobectomy and has a chest tube in place. When assessing the client's three-chamber drainage system, the nurse notes that there is no bubbling in the suction control chamber. Which of the following actions should the nurse take?

• A. Continue to monitor the client as this is an expected finding.
• B. Add more water to the suction control chamber of the drainage system.
• C. Verify that the suction regulator is on and check the tubing for leaks.
• D. Milk the chest tube and dislodge any clots in the tubing that are occluding it.

Correct answer: C

Rationale: In a three-chamber chest drainage system, the absence of bubbling in the suction control chamber indicates that no suction is being applied to the chest tube. The nurse should first verify that the suction regulator is on and check the tubing for any leaks that may be causing the lack of suction. Adding more water to the chamber or milking the chest tube are inappropriate actions and could potentially harm the client. Monitoring the client without taking action could lead to complications if the chest tube is not functioning properly.

3. When working as a professional nurse, what is the priority for a new nurse working on an inpatient medical-surgical unit with a preceptor?

• A. Attending to holistic client needs
• B. Ensuring client safety
• C. Avoiding medication errors
• D. Providing client-focused care

Correct answer: B

Rationale: The priority for a nurse working on an inpatient medical-surgical unit is to ensure client safety. This is crucial as errors in hospital care can lead to preventable deaths. While attending to holistic client needs and providing client-focused care are important aspects of nursing, ensuring client safety takes precedence to prevent harm and promote positive patient outcomes.

4. A nurse is caring for a client with a new diagnosis of type 1 diabetes. What is the most important aspect of teaching the nurse should focus on?

• A. The importance of regular exercise
• B. Proper administration of insulin
• C. Maintaining a low-carbohydrate diet
• D. Recognizing signs of hyperglycemia

Correct answer: B

Rationale: Proper administration of insulin is crucial for clients with type 1 diabetes as they are dependent on insulin for blood glucose control.

5. A healthcare professional is assessing a client who has postoperative atelectasis and is hypoxic. Which of the following manifestations should the healthcare professional expect?

• A. Bradycardia
• B. Bradypnea
• C. Lethargy
• D. Intercostal retractions

Correct answer: D

Rationale: Postoperative atelectasis can lead to hypoxia, which causes respiratory distress. Intercostal retractions, where the muscles between the ribs pull inward during inspiration, are a common sign of respiratory distress in a client with atelectasis. Bradycardia (slow heart rate), Bradypnea (slow breathing rate), and lethargy are not typically associated with atelectasis and hypoxia.
