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 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.

4. A patient experiencing wheezing due to an allergic reaction needs immediate treatment. Which medication should be administered first?

A. Albuterol via nebulizer
B. Cromolyn via nebulizer
C. Aminophylline IV
D. Methylprednisolone IV

Correct answer: A

Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is a rapid-acting bronchodilator that helps relieve wheezing by opening up the airways. During an allergic reaction causing wheezing, prompt relief is crucial, making Albuterol the first-line treatment. Choice B, Cromolyn via nebulizer, is used more for preventing asthma symptoms rather than providing immediate relief. Choice C, Aminophylline IV, is a bronchodilator with a slower onset of action compared to Albuterol. Choice D, Methylprednisolone IV, is a corticosteroid used to reduce inflammation and is not the first-line treatment for acute wheezing in an allergic reaction.

5. What should a healthcare provider monitor for in a patient with hypokalemia?

A. Monitor for muscle weakness
B. Monitor for bradycardia
C. Check deep tendon reflexes
D. Monitor for hyperglycemia

Correct answer: A

Rationale: Corrected Rationale: Muscle weakness is a common symptom of hypokalemia and should be closely monitored in affected patients. Hypokalemia is a condition characterized by low potassium levels in the blood, which can lead to muscle weakness, cramps, and even paralysis. While bradycardia (slow heart rate) can be associated with severe hypokalemia, monitoring for muscle weakness is more specific to the condition. Checking deep tendon reflexes is not typically a primary monitoring parameter for hypokalemia. Monitoring for hyperglycemia is not directly related to hypokalemia, as hypokalemia is primarily associated with potassium levels in the blood.
