1. What are the manifestations of increased intracranial pressure (IICP)?

• A. Restlessness, confusion, irritability
• B. Severe nausea and vomiting
• C. Elevated blood pressure and bradycardia
• D. Decreased heart rate and altered pupil response

Correct answer: A

Rationale: The correct manifestations of increased intracranial pressure (IICP) include restlessness, confusion, and irritability. These symptoms are a result of the brain being under pressure inside the skull. Severe nausea and vomiting (Choice B) are more commonly associated with increased intracranial pressure in children. Elevated blood pressure and bradycardia (Choice C) are not typical manifestations of increased intracranial pressure; instead, hypertension and bradycardia may be seen in Cushing's reflex, which is a late sign of increased IICP. Decreased heart rate and altered pupil response (Choice D) are also not primary manifestations of increased intracranial pressure, although altered pupil response, like a non-reactive or dilated pupil, can be seen in some cases.

2. What is the expected ECG finding in a patient with hypokalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Widened QRS complexes
• D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

3. What is a characteristic sign of hypokalemia on an ECG?

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

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

4. A nurse misreads a blood glucose level and administers excess insulin. What should the nurse monitor for?

• A. Monitor for hyperglycemia
• B. Monitor for hypoglycemia
• C. Administer glucose IV
• D. Monitor for increased thirst

Correct answer: B

Rationale: The correct answer is to monitor for hypoglycemia. Excess insulin can lead to low blood glucose levels, causing hypoglycemia. Symptoms of hypoglycemia include sweating, trembling, dizziness, confusion, and in severe cases, loss of consciousness. Options A, C, and D are incorrect because administering excess insulin would not lead to hyperglycemia or increased thirst, and administering glucose IV would exacerbate the issue by further lowering blood glucose levels.

5. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. Normal chest tube function
• C. A blockage in the chest tube
• D. A malfunction in the drainage system

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This bubbling occurs when air leaks from the patient's pleural space into the chest tube system. It is essential to address this issue promptly to prevent complications like a pneumothorax. Choices B, C, and D are incorrect because continuous bubbling in the water seal chamber is not indicative of normal chest tube function, a blockage in the chest tube, or a malfunction in the drainage system.
