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 is teaching a client who is obese and has obstructive sleep apnea how to decrease the number of nightly apneic episodes. Which of the following client statements indicates an understanding of the teaching?

• A. "It might help if I tried sleeping only on my back."
• B. "I'll sleep better if I take a sleeping pill at night."
• C. "I'll get a humidifier to run at my bedside at night."
• D. "If I could lose about 50 pounds, I might stop having so many apneic episodes."

Correct answer: D

Rationale:

3. A client in a clinic presents with an acute asthma exacerbation. Which of the following medications should reduce the symptoms?

• A. Cromolyn via a metered-dose inhaler
• B. Montelukast orally
• C. Budesonide via a dry-powder inhaler
• D. Albuterol via a jet nebulizer

Correct answer: D

Rationale: During an acute asthma exacerbation, the preferred medication for symptom relief is a short-acting beta-agonist like albuterol, typically delivered via a jet nebulizer for quick onset and efficacy. Cromolyn, montelukast, and budesonide are not as effective for immediate symptom relief in acute exacerbations and are more commonly used for prevention or long-term management of asthma symptoms.

4. A client with heart failure expresses feelings of burden and thoughts of death to a nurse. How should the nurse respond?

• A. Would you like to talk more about this?
• B. You are lucky to have such a devoted daughter.
• C. It is normal to feel as though you are a burden.
• D. Would you like to meet with the chaplain?

Correct answer: A

Rationale: Depression can occur in clients with heart failure, especially in older adults. When a client expresses thoughts of being a burden and death, it is crucial for the nurse to address these concerns. Offering to talk more about the client's feelings provides an opportunity for open communication and a deeper understanding of the client's emotions. Open-ended questions like the one in choice A encourage the client to express themselves freely, leading to better assessment and client-centered care. Choices B and C fail to address the client's emotional distress directly, and choice D diverts the focus without addressing the client's immediate concerns.

5. A client has a newly inserted chest drainage system with a water seal. Which of the following actions should be taken?

• A. Clamp the tube when the client is ambulating.
• B. Keep the collection device below the level of the client's chest.
• C. Carefully coil the tubes to prevent kinking.
• D. Position the client flat to avoid leaks in the tubing.

Correct answer: B

Rationale: Keeping the collection device below the level of the client's chest ensures proper drainage and prevents backflow of fluid into the patient's chest. This position allows gravity to assist in the drainage process. Clamping the tube when the client is ambulating can cause a buildup of pressure in the chest drainage system, potentially leading to complications. Carefully coiling the tubes is important to prevent obstructions and kinks that could impede the flow of drainage. Positioning the client flat may not be ideal as it could hinder proper drainage and increase the risk of leaks in the tubing.
