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 are the common manifestations of a thrombotic stroke?

• A. Gradual loss of function on one side of the body
• B. Sudden loss of consciousness
• C. Severe headache and confusion
• D. Seizures and convulsions

Correct answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. A thrombotic stroke is characterized by a gradual onset of symptoms due to interrupted blood flow in the brain. This interruption results in manifestations such as weakness, numbness, or paralysis on one side of the body. Choices B, C, and D are incorrect because sudden loss of consciousness, severe headache, confusion, seizures, and convulsions are more commonly associated with conditions other than thrombotic strokes.

3. A nurse is caring for a client who has syndrome of inappropriate antidiuretic hormone (SIADH) and is receiving 3% sodium chloride via continuous IV. Which of the following laboratory findings should the nurse identify as an indication that the SIADH is resolving?

• A. Urine specific gravity 1.020
• B. Sodium 119 mEq/L
• C. BUN 8 mg/dL
• D. Calcium 8.7 mg/dL

Correct answer: A

Rationale: A urine specific gravity of 1.020 is within the expected reference range and indicates that the kidneys are appropriately concentrating urine, which is a sign that the syndrome of inappropriate antidiuretic hormone (SIADH) is resolving. A low sodium level (choice B) is associated with SIADH, so a sodium level of 119 mEq/L is not indicative of resolution. BUN (choice C) and calcium levels (choice D) are typically not directly related to SIADH resolution.

4. What are the early signs of increased intracranial pressure (IICP)?

• A. Restlessness, irritability, and confusion
• B. Sudden onset of seizures
• C. Decreased heart rate and pupillary response
• D. Loss of consciousness

Correct answer: A

Rationale: The correct answer is A: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These signs indicate that the brain is starting to experience pressure, often due to conditions such as trauma, tumors, or hemorrhage. Sudden onset of seizures (choice B) is not typically an early sign of IICP but can occur later as the pressure increases. Decreased heart rate and pupillary response (choice C) are more indicative of late-stage IICP as the brainstem becomes compromised. Loss of consciousness (choice D) is a late sign of IICP when the pressure has significantly increased and is causing significant brain dysfunction.

5. What ECG changes are expected in a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Widened QRS complexes
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.
