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 nurse assesses a client who has a mediastinal chest tube. Which symptoms require the nurse's immediate intervention? (Select ONE that does not apply)

• A. Production of pink sputum
• B. Tracheal deviation
• C. Pain at insertion site
• D. Sudden onset of shortness of breath

Correct answer: A

Rationale: In a client with a mediastinal chest tube, the presence of pink sputum does not necessarily require immediate intervention. However, tracheal deviation could indicate a tension pneumothorax, sudden shortness of breath could signal tube issues or pneumothorax, and drainage exceeding 70 mL/hr might suggest hemorrhage. Disconnection at the Y site could lead to air entering the tubing, necessitating prompt attention.

3. A nurse in an emergency room is caring for a client who sustained partial-thickness burns to both lower legs, chest, face, and both forearms. Which of the following is the priority action the nurse should take?

• A. Insert an indwelling urinary catheter.
• B. Inspect the mouth for signs of inhalation injuries.
• C. Administer intravenous pain medication.
• D. Draw blood for a complete blood cell (CBC) count.

Correct answer: B

Rationale: When caring for a client with burns, especially burns to the face and chest, the priority action for the nurse is to inspect the mouth for signs of inhalation injuries. Inhalation injuries can be life-threatening and may not be immediately apparent. Identifying these injuries early allows for prompt intervention and can significantly impact the client's outcomes. While other actions such as pain management and blood tests are important, assessing for inhalation injuries takes precedence due to its critical nature.

4. A client with chronic obstructive pulmonary disease is being taught by a nurse. Which nutritional information should the nurse include in the teaching? (SATA)

• A. Avoid drinking fluids just before and during meals.
• B. Rest before meals if you have dyspnea.
• C. Have about six small meals a day.
• D. Eat high-fiber foods to promote gastric emptying.

Correct answer: D

Rationale: In chronic obstructive pulmonary disease, it's important to consider the impact of nutrition on respiratory function. Eating high-fiber foods can lead to increased gas production, causing abdominal bloating and potentially worsening shortness of breath. Therefore, it is advisable for clients with COPD to avoid high-fiber foods to prevent these issues. Resting before meals can help manage dyspnea, and having smaller, more frequent meals can prevent bloating. Increasing calorie and protein intake is essential to prevent malnourishment in COPD patients. Additionally, limiting carbohydrate intake is crucial as it can increase carbon dioxide production, leading to a higher risk of acidosis in these individuals.

5. A client with heart failure has gained 2 kg (4.4 lbs) in the past 24 hours. What action should the nurse take first?

• A. Restrict the client's fluid intake.
• B. Assess the client's respiratory status.
• C. Administer diuretics as ordered.
• D. Notify the healthcare provider.

Correct answer: B

Rationale: Assessing the client's respiratory status is the priority as it helps determine if the weight gain is due to fluid retention affecting breathing. This assessment is crucial in addressing the immediate concern of potential respiratory distress before implementing interventions like fluid restriction, diuretics, or notifying the healthcare provider.
