Nursing Elites

1. After coronary artery bypass graft surgery, a male client is admitted to the coronary care unit. Which nursing diagnosis is of the highest priority?

• A. Ineffective breathing pattern.
• B. Impaired gas exchange.
• C. Acute pain.
• D. Risk for infection.

Correct answer: B

Rationale: Impaired gas exchange is the highest priority nursing diagnosis because it directly impacts the client's oxygenation. Following coronary artery bypass graft surgery, ensuring adequate oxygen exchange is crucial for the client's recovery. Ineffective breathing pattern, although important, may not be as critical as impaired gas exchange in the immediate postoperative period. Acute pain, while significant, can be managed effectively with appropriate interventions and is not as emergent as addressing impaired gas exchange. Risk for infection is also a valid concern post-surgery, but ensuring optimal gas exchange takes precedence to prevent complications associated with inadequate oxygenation.

2. The healthcare provider is caring for a client with a chest tube. Which observation indicates that the chest tube is functioning effectively?

• A. Continuous bubbling in the water-seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation (tidaling) in the water-seal chamber.
• D. Drainage of clear, pale yellow fluid from the chest tube.

Correct answer: B

Rationale: Intermittent bubbling in the suction control chamber is the correct observation indicating effective functioning of the chest tube. This bubbling signifies that the suction system is working correctly and maintaining the desired negative pressure in the pleural space. Continuous bubbling in the water-seal chamber suggests an air leak, which is not a normal finding. No fluctuation (tidaling) in the water-seal chamber may indicate a blockage or lack of communication between the pleural space and the water-seal, which is not ideal. Drainage of clear, pale yellow fluid from the chest tube is a normal finding, but it does not specifically indicate the effectiveness of the chest tube function.

3. The healthcare provider is assessing a client with a suspected myocardial infarction. Which finding requires immediate intervention?

• A. Chest pain radiating to the left arm.
• B. Shortness of breath.
• C. Nausea and vomiting.
• D. Diaphoresis.

Correct answer: B

Rationale: Shortness of breath is a critical sign that can indicate heart failure or pulmonary edema, conditions that require immediate intervention in a client with a suspected myocardial infarction. Chest pain radiating to the left arm is a classic symptom of a myocardial infarction but may not necessitate immediate intervention compared to severe shortness of breath. Nausea and vomiting can be present in myocardial infarction but are not as urgent as shortness of breath. Diaphoresis, or sweating, is a common symptom of a myocardial infarction but may not be as immediately concerning as significant shortness of breath.

4. A client is suspected of being poisoned and presents with symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth. The nurse should consider these findings consistent with which potential bioterrorism agent?

• A. ricin
• B. botulism toxin
• C. sulfur mustard
• D. yersinia pestis

Correct answer: B

Rationale: The correct answer is B: botulism toxin. The symptoms described, including symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth, are classic manifestations of botulism, which is caused by a toxin produced by Clostridium botulinum. This toxin affects the nervous system, leading to muscle weakness and paralysis. Choice A, ricin, typically presents with gastrointestinal symptoms and organ failure. Choice C, sulfur mustard, causes blistering skin and respiratory issues. Choice D, yersinia pestis, is associated with the plague and presents with fever, chills, weakness, and swollen lymph nodes.

5. The nurse is caring for a client with cirrhosis of the liver. Which laboratory result requires immediate intervention?

• A. Serum albumin of 3.5 g/dL.
• B. Prothrombin time (PT) of 12 seconds.
• C. Hemoglobin of 10 g/dL.
• D. Serum ammonia level of 180 mcg/dL.

Correct answer: D

Rationale: The correct answer is D, the serum ammonia level of 180 mcg/dL. An elevated serum ammonia level indicates hepatic dysfunction and can lead to hepatic encephalopathy, which is a medical emergency requiring immediate intervention. Options A, B, and C are within normal ranges or slightly abnormal values for clients with cirrhosis and do not pose an immediate threat. Serum albumin levels may indicate malnutrition, prothrombin time may reflect liver synthetic function, and hemoglobin levels can be affected by various factors but do not require immediate intervention in this scenario.
