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 acute respiratory distress syndrome (ARDS) requires care planning. Which of the following interventions should be included in the plan?

• A. Administer low-flow oxygen continuously via nasal cannula.
• B. Encourage oral intake of at least 3,000 mL of fluids per day.
• C. Offer high-protein and high-carbohydrate foods frequently.
• D. Place in a prone position

Correct answer: D

Rationale: In acute respiratory distress syndrome (ARDS), placing the client in a prone position helps improve ventilation-perfusion matching and oxygenation. This position can optimize lung function and is a beneficial intervention for clients with ARDS. Administering low-flow oxygen via nasal cannula, encouraging oral intake of excess fluids, or offering high-protein and high-carbohydrate foods are not primary interventions for ARDS and may not directly address the respiratory distress experienced by the client.

3. A client is moving to a new state and needs to find a new doctor and hospital there. What advice by the nurse is best?

• A. Ask the hospitals there about standard nurse-client ratios.
• B. Choose the hospital that has the newest technology.
• C. Find a hospital that is accredited by The Joint Commission.
• D. Use a facility affiliated with a medical or nursing school.

Correct answer: C

Rationale: Choosing a hospital accredited by The Joint Commission (TJC) or another accrediting body is the best advice as it ensures a focus on safety and quality standards.

4. A student is practicing suctioning a tracheostomy in the skills laboratory. What action by the student demonstrates that more teaching is needed?

• A. Applying suction while withdrawing the catheter
• B. Preoxygenating the client before suctioning
• C. Suctioning up to three times if necessary
• D. Suctioning for a duration of 10 to 15 seconds each time

Correct answer: A

Rationale: The correct technique for suctioning a tracheostomy involves applying suction while withdrawing the catheter to avoid damaging the tracheal mucosa. Therefore, the student applying suction while inserting the catheter indicates a need for further teaching. Preoxygenating the client, suctioning up to three times if necessary, and limiting suctioning to 10 to 15 seconds each time are all appropriate actions in tracheostomy suctioning.

5. A client is postoperative with shallow respirations at 9/min. Which acid-base imbalance should the nurse identify the client as being at risk for developing initially?

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

Correct answer: A

Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.
