1. What is a characteristic sign of hypokalemia on an ECG?

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

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

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. A patient who received an enema reports abdominal cramping. What should the nurse do?

• A. Increase the flow of the enema solution
• B. Lower the height of the enema solution container
• C. Remove the enema tubing
• D. Stop the procedure

Correct answer: B

Rationale: When a patient who received an enema reports abdominal cramping, the nurse should lower the height of the enema solution container. This adjustment can help reduce the cramping by slowing down the flow of the solution into the colon, allowing the patient to tolerate the procedure better. Increasing the flow of the solution (Choice A) can exacerbate the cramping. Removing the enema tubing (Choice C) or stopping the procedure (Choice D) may not address the issue and could lead to incomplete treatment.

4. A patient with chronic kidney disease may require dietary restrictions. Which of the following diets should the healthcare provider prescribe?

• A. Low sodium diet
• B. Potassium restricted diet
• C. High phosphorus diet
• D. High protein diet

Correct answer: B

Rationale: Patients with chronic kidney disease often require a potassium-restricted diet to help manage their electrolyte levels. Excessive potassium intake can be harmful to individuals with compromised kidney function. While monitoring sodium intake is also important for these patients, a low sodium diet is not specifically indicated in the question. High phosphorus diet and high protein diet are not recommended for individuals with chronic kidney disease as they can further stress the kidneys and worsen the condition.

5. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

• A. Synchronized cardioversion
• B. Defibrillation
• C. Pacing
• D. Medication administration

Correct answer: A

Rationale: The correct answer is A: Synchronized cardioversion. In ventricular tachycardia with a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat tachyarrhythmias where there is a pulse present. Defibrillation (choice B) is used in emergencies for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (choice C) is more suitable for bradycardias or certain conduction abnormalities. Medication administration (choice D) may be used in stable cases or as an adjunct to other treatments, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.
