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 healthcare provider assesses a client with pneumonia. Which clinical manifestation should the provider expect to find?

• A. Fremitus
• B. Hyperresonance
• C. Dullness on percussion
• D. Decreased tactile fremitus

Correct answer: C

Rationale: Pneumonia often leads to the consolidation of lung tissue, resulting in dullness on percussion. This occurs due to the presence of fluid or inflammatory material in the alveoli. Fremitus and decreased tactile fremitus are more indicative of conditions like pleural effusion or pneumothorax, where there is an increase in the density of the pleural space or air in the pleural cavity. Hyperresonance, on the other hand, is typically associated with conditions causing air trapping, such as emphysema, where there is increased air in the alveoli.

3. A client has developed atelectasis postoperatively. Which of the following findings should the nurse expect?

• A. Facial flushing
• B. Increasing dyspnea
• C. Decreasing respiratory rate
• D. Friction rub

Correct answer: B

Rationale: Atelectasis is a condition where the alveoli in the lungs collapse, leading to impaired gas exchange. As a result, the client may experience increasing dyspnea (difficulty breathing) due to the decreased lung capacity for oxygen exchange. Facial flushing, decreasing respiratory rate, and friction rub are not typically associated with atelectasis.

4. A client is in the immediate postoperative period following a partial laryngectomy. Which of the following parameters should the nurse assess first?

• A. Pain severity
• B. Wound drainage
• C. Tissue integrity
• D. Airway patency

Correct answer: D

Rationale: In a client following a partial laryngectomy, the priority assessment is always airway patency. This is crucial to ensure that the client can breathe adequately and prevent any complications related to airway obstruction. Monitoring airway patency takes precedence over other assessments such as pain severity, wound drainage, and tissue integrity. Any compromise in airway patency requires immediate intervention to maintain the client's respiratory function and safety.

5. A client develops a pulmonary embolism. Which of the following interventions should the nurse implement first?

• A. Give morphine IV.
• B. Administer oxygen therapy.
• C. Start an IV infusion of lactated Ringer's.
• D. Initiate cardiac monitoring.

Correct answer: B

Rationale: Administering oxygen therapy is the priority intervention for a client with a pulmonary embolism. Oxygen helps improve oxygenation levels and decrease the workload on the heart. It is crucial to ensure adequate oxygenation before other interventions are initiated. Morphine IV, starting an IV infusion of lactated Ringer's, and initiating cardiac monitoring are important interventions but come after ensuring adequate oxygenation.
