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 with dyspnea and difficulty climbing stairs is classified as having class III dyspnea. Which intervention should the nurse include in the client's plan of care?

• A. Assistance with activities of daily living.
• B. Daily physical therapy activities.
• C. Oxygen therapy at 2 liters per nasal cannula.
• D. Complete bedrest with frequent repositioning.

Correct answer: A

Rationale: Class III dyspnea indicates significant limitations in activity due to shortness of breath. Clients with this level of dyspnea should be encouraged to participate in activities within their tolerance levels. Providing assistance with activities of daily living helps conserve energy for essential tasks while promoting independence. Oxygen therapy is only necessary if hypoxia is present, and complete bedrest is generally not recommended for clients with dyspnea unless specifically indicated.

3. A nurse assesses a client who has a history of heart failure. Which question should the nurse ask to assess the extent of the client's heart failure?

• A. Do you have trouble breathing or chest pain?
• B. Are you able to walk upstairs without fatigue?
• C. Do you awake with breathlessness during the night?
• D. Do you have new-onset heaviness in your legs?

Correct answer: B

Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.

4. After a thoracentesis, a healthcare provider assesses a client. Which assessment finding warrants immediate action?

• A. The client rates pain as 5/10 at the site of the procedure.
• B. A small amount of drainage is noted from the site.
• C. Pulse oximetry reads 93% on 2 liters of oxygen.
• D. The trachea is deviated toward the opposite side of the neck.

Correct answer: D

Rationale: A deviated trachea indicates a tension pneumothorax, a life-threatening emergency. This condition can rapidly lead to respiratory failure and requires immediate intervention. The other assessment findings, such as pain level, mild drainage, and slightly decreased oxygen saturation, are within an expected range after a thoracentesis and do not indicate an immediate threat to the client's life.

5. A client in the intensive care unit is receiving teaching before removal of an endotracheal tube. Which of the following instructions should the nurse include in the teaching?

• A. Rest in a side-lying position after the tube is removed.
• B. Use the incentive spirometer every 4 hours after the tube is removed.
• C. Avoid speaking for extended periods.
• D. Vital signs will be monitored by a nurse every 15 minutes in the first hour after the tube is removed.

Correct answer: C

Rationale: It is essential to advise the client to avoid speaking for extended periods after the removal of the endotracheal tube to prevent strain on the vocal cords and allow the airway to recover. Speaking for prolonged periods can lead to irritation and potentially affect the healing process. The other options are also important post-extubation instructions, such as using the incentive spirometer to maintain lung function, positioning in a side-lying position for comfort, and frequent monitoring of vital signs to ensure the client's stability.
