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 has an oxygen saturation of 88% on room air. Which action should the nurse take first?

• A. Initiate oxygen therapy at 2 liters per minute via nasal cannula.
• B. Place the client in a high-Fowler's position.
• C. Notify the healthcare provider.
• D. Document the finding in the client's medical record.

Correct answer: A

Rationale: The priority action for a client with an oxygen saturation of 88% on room air is to initiate oxygen therapy to improve oxygen saturation levels. Oxygen therapy is crucial to address hypoxemia promptly. Placing the client in a high-Fowler's position can also aid in oxygenation, but administering oxygen takes precedence. While notifying the healthcare provider is important, it is a secondary action after ensuring the client's immediate need for oxygen is met. Documenting the finding in the client's medical record is necessary for continuity of care but is not the primary intervention when addressing hypoxemia.

3. A client is 12 hours postoperative and has a chest tube to a disposable water-seal drainage system with suction. The healthcare provider should intervene for which of the following observations?

• A. Constant bubbling in the suction-control chamber
• B. Continuous bubbling in the water-seal chamber
• C. Bloody drainage in the collection chamber
• D. Fluid-level fluctuations in the water-seal chamber

Correct answer: B

Rationale: Continuous bubbling in the water-seal chamber indicates an air leak, which can compromise the system's integrity and affect the client's respiratory status. The other options are expected findings in a client with a chest tube drainage system: constant bubbling in the suction-control chamber indicates proper suction function, bloody drainage in the collection chamber is expected in the immediate postoperative period, and fluid-level fluctuations in the water-seal chamber demonstrate normal drainage and lung re-expansion.

4. A client has a pleural chest tube. Which action should the nurse take to ensure safe use of this equipment?

• A. Never strip the tubing to maintain patency.
• B. Secure tubing junctions with tape to prevent accidental disconnections.
• C. Set wall suction at the level recommended by the device manufacturer.
• D. Keep padded clamps at the bedside for use if the drainage system is interrupted.

Correct answer: D

Rationale: To ensure safe use of a pleural chest tube, the nurse should keep padded clamps at the bedside for use if the drainage system becomes dislodged or is interrupted. Stripping the tubing should never be done to maintain patency. Tubing junctions should be secured with tape, not clamps. Wall suction should be set at the level recommended by the device manufacturer, not the provider.

5. A nurse collaborates with a respiratory therapist to complete pulmonary function tests (PFTs) for a client. Which statements should the nurse include in communications with the respiratory therapist prior to the tests? (Select all that apply)

• A. I held the client's morning bronchodilator medication.
• B. The client is ready to go down to radiology for this examination.
• C. Physical therapy states the client can run on a treadmill.
• D. I advised the client not to smoke for 6 hours prior to the test.

Correct answer: B

Rationale: Communication between the nurse and respiratory therapist is crucial before pulmonary function tests (PFTs). It is important to inform the respiratory therapist that the client is ready for the examination. The nurse should not administer bronchodilator medication before the test as it may affect the results, and the client should not smoke for 6 to 8 hours prior to the test to ensure accurate results. Additionally, PFTs do not involve running on a treadmill; instead, the client may be required to perform specific breathing maneuvers as instructed by the respiratory therapist.
