1. What are the expected ECG findings in hypokalemia?

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

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

2. 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.

3. What ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.

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

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

Correct answer: A

Rationale: In a patient with ventricular tachycardia and a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat unstable tachyarrhythmias like ventricular tachycardia with a pulse. Choice B, defibrillation, is used for pulseless ventricular tachycardia or ventricular fibrillation. Choice C, medication administration, may not provide immediate correction for unstable ventricular tachycardia. Choice D, pacing, is not the first-line treatment for ventricular tachycardia with a pulse.

5. A home health nurse is providing teaching to the family of a client who has a seizure disorder. Which of the following interventions should the nurse include in the teaching?

• A. Keep a padded tongue depressor near the bedside
• B. Place a pillow under the client's head during a seizure
• C. Administer diazepam intravenously at the onset of seizures
• D. Position the client on their side during a seizure

Correct answer: D

Rationale: The correct intervention for a client who has a seizure disorder is to position the client on their side during a seizure. This helps to prevent aspiration and ensures a patent airway. Keeping a padded tongue depressor near the bedside (Choice A) is not recommended as it can cause injury during a seizure. Placing a pillow under the client's head during a seizure (Choice B) is also not advised as it can obstruct the airway. Administering diazepam intravenously at the onset of seizures (Choice C) is not typically done at home without healthcare provider direction.
