Nursing Elites

1. What ECG changes should be monitored in a patient with hypokalemia?

• A. Flattened T waves and prominent U waves
• B. Elevated ST segments and wide QRS complexes
• C. Tall T waves and flattened QRS complexes
• D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. A nurse is providing dietary teaching for a client who has chronic cholecystitis. Which of the following diets should the nurse recommend?

• A. Low potassium diet
• B. High fiber diet
• C. Low fat diet
• D. Low sodium diet

Correct answer: C

Rationale: The correct answer is C: Low fat diet. A low-fat diet is recommended for clients with chronic cholecystitis to reduce episodes of biliary colic. High-fat foods can trigger symptoms by causing the gallbladder to contract, leading to pain. Choice A, a low potassium diet, is not specifically indicated for chronic cholecystitis. Choice B, a high fiber diet, though generally healthy, may worsen symptoms in some individuals with cholecystitis due to the increased intestinal gas production. Choice D, a low sodium diet, is not directly related to the management of chronic cholecystitis.

3. 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.

4. What are the early signs of hypokalemia on an ECG?

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

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

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

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

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.
