Nursing Elites

1. A patient with hypokalemia is being monitored. What should the nurse assess for?

• A. Muscle weakness
• B. Flattened T waves
• C. Checking deep tendon reflexes
• D. Seizures

Correct answer: A

Rationale: Corrected Question: A patient with hypokalemia is being monitored. What should the nurse assess for? Corrected Choice A: Muscle weakness Corrected Choice B: Flattened T waves Corrected Choice C: Checking deep tendon reflexes Corrected Choice D: Seizures Rationale: Hypokalemia is associated with muscle weakness due to the effect of low potassium levels on muscle function. Flattened T waves on an ECG are characteristic of hypokalemia but are not a direct assessment for the patient's condition. Checking deep tendon reflexes and seizures are not primary symptoms associated with hypokalemia, making them less relevant for monitoring a patient with this electrolyte imbalance.

2. A client is scheduled for an electroencephalogram (EEG) and a nurse is providing teaching. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should not wash my hair prior to the procedure.
• B. I will receive a sedative 1 hour before the procedure.
• C. I should avoid eating prior to the procedure.
• D. I will be exposed to flashes of light during the procedure.

Correct answer: D

Rationale: The correct answer is D. The nurse should inform the client that flashes of light or pictures are often used during the procedure to assess the brain's response to stimuli. Choices A, B, and C are incorrect because washing hair, receiving a sedative, and avoiding eating are not directly related to the EEG procedure.

3. What is the most likely cause of continuous bubbling in the water seal chamber of a chest tube?

• A. An air leak
• B. A blockage in the chest tube
• C. Normal chest tube function
• D. Drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube usually indicates an air leak. An air leak can disrupt the negative pressure required for the chest tube to function properly, leading to inadequate drainage and potential complications. A blockage in the chest tube would typically result in decreased or absent drainage rather than continuous bubbling. Normal chest tube function does not involve continuous bubbling in the water seal chamber. Drainage from the chest tube may lead to fluid moving into the drainage system, but it would not cause continuous bubbling in the water seal chamber.

4. 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.

5. If a nurse misread a glucose reading as 210 mg/dL instead of 120 mg/dL and administered insulin, what should the nurse monitor for?

• A. Monitor for hypoglycemia
• B. Monitor for hyperglycemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. In this scenario, the nurse administered insulin based on an incorrect glucose reading, which could lead to a drop in blood sugar levels. Monitoring for hypoglycemia is crucial to prevent any adverse effects on the patient's health. Choice B, monitoring for hyperglycemia, is incorrect as the administration of insulin can lead to low blood sugar levels, not high. Choice C, administering glucose IV, is not the immediate action needed as monitoring for hypoglycemia comes first. Choice D, documenting the incident, is important but not the initial priority when patient safety is at risk.
