Nursing Elites

1. A nurse is assessing a client who has a sodium level of 122 mEq/L. Which of the following findings should the nurse expect?

• A. Decreased deep tendon reflexes
• B. Positive Chvostek's sign
• C. Hyperactive bowel sounds
• D. Dry mucous membranes

Correct answer: A

Rationale: Corrected deep tendon reflexes occur with hyponatremia. Other manifestations of hyponatremia include headache, confusion, lethargy, fatigue, seizures, and muscle weakness. Positive Chvostek's sign is associated with hypocalcemia, hyperactive bowel sounds are not typically related to hyponatremia, and dry mucous membranes are more commonly seen with dehydration.

2. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. A blocked chest tube
• C. Normal chest tube function
• D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak in the system. This occurs when air is entering the system through a leak, preventing the lung from fully re-expanding. Choice B, a blocked chest tube, is incorrect as a blocked tube would result in a lack of drainage rather than continuous bubbling. Choice C, normal chest tube function, is incorrect as continuous bubbling signifies an issue. Choice D, continuous drainage from the chest tube, is incorrect as bubbling in the water seal chamber specifically indicates an air leak, not just the presence of drainage.

3. What is the most likely cause of continuous bubbling in the water seal chamber of a chest tube?

• A. An air leak
• B. A blockage in the chest tube
• C. Normal chest tube function
• D. Drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube usually indicates an air leak. An air leak can disrupt the negative pressure required for the chest tube to function properly, leading to inadequate drainage and potential complications. A blockage in the chest tube would typically result in decreased or absent drainage rather than continuous bubbling. Normal chest tube function does not involve continuous bubbling in the water seal chamber. Drainage from the chest tube may lead to fluid moving into the drainage system, but it would not cause continuous bubbling in the water seal chamber.

4. Which ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic ECG change seen in hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac cycle, leading to T wave abnormalities. Prominent U waves are typically seen in hypokalemia. Elevated ST segments are more indicative of myocardial infarction or pericarditis. Widened QRS complexes are commonly associated with conditions like bundle branch blocks or certain toxicities.

5. A nurse is planning care for a client who has acute post-streptococcal glomerulonephritis. Which of the following interventions should the nurse include in the client's plan?

• A. Encourage a high-protein diet
• B. Increase the client's fluid intake
• C. Administer diuretics
• D. Weigh the client twice a week

Correct answer: C

Rationale: Administering diuretics is a crucial intervention for a client with acute post-streptococcal glomerulonephritis as it helps reduce edema by increasing urine output and managing symptoms of glomerulonephritis. Encouraging a high-protein diet (Choice A) is not recommended in this case because it can put additional stress on the kidneys. Increasing fluid intake (Choice B) may worsen edema in these clients. Weighing the client twice a week (Choice D) is important for monitoring fluid balance but is not as immediate and directly beneficial as administering diuretics.
