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 planning care for a group of postoperative clients. Which of the following interventions should the nurse identify as the priority?

• A. Administer IV pain medication to a client who reports pain as a 6 on a scale of 0 to 10
• B. Administer oxygen to a client who has an oxygen saturation of 91%
• C. Instruct a client who is 1 hr postoperative about coughing and deep breathing exercises
• D. Initiate an infusion of 0.9% sodium chloride for a client who has just had abdominal surgery

Correct answer: B

Rationale: The priority intervention is administering oxygen. Postoperatively, the client's oxygen saturation should be at or above 95%. Oxygen is essential for tissue perfusion and cellular oxygenation. While managing pain is important, oxygenation takes precedence. Instructing a client about coughing and deep breathing exercises is important for preventing respiratory complications but is not as urgent as addressing low oxygen saturation. Initiating an infusion of 0.9% sodium chloride is a routine postoperative intervention for fluid balance but is not the priority when oxygen saturation is low.

3. What should a healthcare professional do if a patient experiences abdominal cramping during enema administration?

• A. Lower the height of the enema solution container
• B. Stop the procedure and remove the tubing
• C. Continue the enema at a slower rate
• D. Increase the flow of the enema solution

Correct answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the healthcare professional should lower the height of the enema solution container. This action helps relieve the cramping by slowing down the flow of the enema solution, making it more comfortable for the patient. Stopping the procedure and removing the tubing (Choice B) may be necessary in some cases, but it should not be the first step when cramping occurs. Continuing the enema at a slower rate (Choice C) may exacerbate the cramping, so it is not the best course of action. Increasing the flow of the enema solution (Choice D) will likely worsen the cramping and should be avoided.

4. What dietary modifications are recommended for a patient with pre-dialysis kidney disease?

• A. Limit phosphorus intake to 700 mg/day
• B. Increase sodium intake to 3 g/day
• C. Restrict protein intake to 0.55-0.60 g/kg/day
• D. Eat three large meals per day

Correct answer: A

Rationale: The correct answer is A: Limit phosphorus intake to 700 mg/day. Patients with pre-dialysis kidney disease should limit phosphorus intake to prevent further kidney damage. Excessive phosphorus can lead to mineral and bone disorders. Choice B is incorrect because increasing sodium intake is not recommended in pre-dialysis kidney disease. Choice C is incorrect as protein restriction is a common recommendation in advanced kidney disease, not pre-dialysis. Choice D is incorrect as eating three large meals per day is not a specific dietary modification for pre-dialysis kidney disease.

5. What is the priority intervention when continuous bubbling is observed in the water seal chamber of a chest tube?

• A. Check for an air leak
• B. Continue monitoring as it is not normal
• C. Replace the chest tube system
• D. Tighten the tube connections

Correct answer: A

Rationale: The correct answer is to 'Check for an air leak.' Continuous bubbling in the water seal chamber of a chest tube indicates an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Checking for an air leak is crucial to prevent respiratory complications. Choice B is incorrect because continuous bubbling is not normal and requires immediate intervention to address the air leak. Choice C is incorrect as replacing the entire chest tube system is not the initial priority when an air leak is suspected. Choice D is incorrect because tightening tube connections may not address the underlying issue of an air leak and should not be the initial action taken in this situation.
