Nursing Elites

1. A client is scheduled for an electroencephalogram (EEG) and a nurse is providing teaching. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should not wash my hair prior to the procedure.
• B. I will receive a sedative 1 hour before the procedure.
• C. I should avoid eating prior to the procedure.
• D. I will be exposed to flashes of light during the procedure.

Correct answer: D

Rationale: The correct answer is D. The nurse should inform the client that flashes of light or pictures are often used during the procedure to assess the brain's response to stimuli. Choices A, B, and C are incorrect because washing hair, receiving a sedative, and avoiding eating are not directly related to the EEG procedure.

2. A client has a right-sided pneumothorax, and a chest tube is inserted. Which finding indicates that the chest drainage system is functioning correctly?

• A. Gentle bubbling in the suction chamber
• B. Crepitus around the insertion site
• C. Constant bubbling in the water seal chamber
• D. Absence of breath sounds on the right side

Correct answer: A

Rationale: In a chest drainage system, gentle bubbling in the suction chamber indicates proper functioning, showing that the system is connected and working effectively to remove air or fluid from the pleural space. Crepitus around the insertion site (Choice B) suggests subcutaneous emphysema, not chest tube functionality. Constant bubbling in the water seal chamber (Choice C) indicates an air leak. Absence of breath sounds on the right side (Choice D) is indicative of the pneumothorax, not the chest tube function.

3. What are the common manifestations of compartment syndrome?

• A. Unrelieved pain, pallor, pulselessness
• B. Redness and swelling
• C. Fever and infection
• D. Swelling and redness

Correct answer: A

Rationale: The correct manifestations of compartment syndrome are unrelieved pain, pallor, and pulselessness. These symptoms indicate compromised blood flow and neurovascular compromise, necessitating immediate medical intervention. Redness and swelling (Choice B) are more commonly associated with inflammation or infection rather than compartment syndrome. Fever and infection (Choice C) are not typical manifestations of compartment syndrome. Swelling and redness (Choice D) are general signs that can be seen in various conditions and are not specific to compartment syndrome.

4. How does hyponatremia place the patient at risk?

• A. Seizures
• B. Fatigue
• C. Cardiac dysrhythmias
• D. Muscle weakness

Correct answer: C

Rationale: Hyponatremia places the patient at risk for cardiac dysrhythmias. While hyponatremia can lead to seizures due to cerebral edema caused by fluid imbalance, the most immediate and life-threatening risk is cardiac dysrhythmias. Low sodium levels can disrupt the heart's electrical activity, potentially leading to fatal arrhythmias. Although fatigue and muscle weakness are symptoms of hyponatremia, cardiac dysrhythmias pose the most critical concern as they can have severe consequences.

5. What are the expected ECG changes in hypokalemia?

• A. Flattened T waves
• B. ST elevation
• C. Wide QRS complex
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
