Nursing Elites

1. A client is hospitalized with a second episode of pulmonary embolism (PE). Recent genetic testing reveals the client has an alteration in the gene CYP2C19. What action by the nurse is best?

• A. Instruct the client to eliminate all vitamin K from the diet.
• B. Prepare preoperative teaching for an inferior vena cava (IVC) filter.
• C. Refer the client to a chronic illness support group.
• D. Teach the client to use a soft-bristled toothbrush.

Correct answer: B

Rationale: Clients with an alteration in the CYP2C19 gene do not metabolize warfarin (Coumadin) well, leading to higher blood levels and more side effects. As this client is a poor candidate for warfarin therapy, the prescriber will most likely recommend the implantation of an inferior vena cava (IVC) filter. This device helps prevent blood clots from reaching the lungs, reducing the risk of pulmonary embolism.

2. During an acute asthma attack in a client with asthma, what medication should the nurse administer first?

• A. Oral corticosteroids
• B. Short-acting beta agonist
• C. Leukotriene receptor antagonist
• D. Long-acting beta agonist

Correct answer: B

Rationale: During an acute asthma attack, the priority is to quickly relieve bronchospasm and improve breathing. Short-acting beta agonists, like albuterol, are the first-line medications as they rapidly relax bronchial muscles, providing immediate relief. Oral corticosteroids are used as adjunct therapy to reduce airway inflammation over time, while leukotriene receptor antagonists and long-acting beta agonists are not appropriate for immediate relief during an acute attack.

3. 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.

4. A client is postoperative, and a nurse is developing a plan of care. Which of the following interventions should the nurse include in the plan to prevent pulmonary complications?

• A. Perform range-of-motion exercises
• B. Place suction equipment at the bedside
• C. Encourage the use of an incentive spirometer
• D. Administer an expectorant

Correct answer: C

Rationale: Encouraging the use of an incentive spirometer is vital in preventing pulmonary complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, promoting lung expansion, and preventing atelectasis. Range-of-motion exercises help prevent musculoskeletal complications, while placing suction equipment at the bedside is important but not directly related to preventing pulmonary complications. Administering an expectorant may help with clearing secretions but is not as effective in preventing postoperative pulmonary complications as using an incentive spirometer.

5. 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.
