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 working on a cardiac unit delegated taking vital signs to an experienced unlicensed assistive personnel (UAP). Four hours later, the nurse notes the client's blood pressure is much higher than previous readings & the client's mental status has changed. What action by the nurse would most likely have prevented this negative outcome?

• A. Determining if the UAP knew how to take blood pressure
• B. Double-checking the UAP by taking another blood pressure
• C. Providing more appropriate supervision of the UAP
• D. Taking the blood pressure instead of delegating the task

Correct answer: C

Rationale: The most likely action by the nurse that would have prevented the negative outcome is providing more appropriate supervision of the UAP. Supervision is essential in delegation as it involves directing, evaluating, and following up on delegated tasks. By providing adequate supervision, the nurse can ensure that tasks are performed correctly and promptly identify any issues or abnormalities, such as a significant change in vital signs or the client's mental status. This proactive approach can help prevent adverse outcomes and enhance patient safety.

3. During an asthma attack, a healthcare provider is assessing a client for hypoxemia. Which of the following manifestations should the provider expect?

• A. Nausea
• B. Dysphagia
• C. Agitation
• D. Hypotension

Correct answer: C

Rationale: During an asthma attack, hypoxemia can lead to inadequate oxygen supply to the brain, causing symptoms like restlessness, confusion, and agitation. These manifestations result from the body's response to low oxygen levels, aiming to increase oxygenation. Nausea, dysphagia, and hypotension are not typical manifestations of hypoxemia during an asthma attack.

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. During pulmonary hygiene for a client with pneumonia, a nurse positions the client on his left side in Trendelenburg position. From which of the following lung segments should the nurse expect secretions to be mobilized with the client in this position?

• A. Lateral segment of the left lower lobe
• B. Lateral segment of the right lower lobe
• C. Posterior segment of the right middle lobe
• D. Posterior segment of the right lower lobe

Correct answer: B

Rationale: When a client is positioned on the left side in Trendelenburg position for pulmonary hygiene, secretions are expected to be mobilized from the lateral segment of the right lower lobe. This positioning helps facilitate drainage and clearance of secretions from this specific area of the lung, aiding in overall pulmonary hygiene and improving ventilation.
