1. What ECG changes are seen in hypokalemia?

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

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

2. What is the first medication to give to a patient with wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Methylprednisolone 100 mg IV
• C. Cromolyn 20 mg via nebulizer
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it is a fast-acting bronchodilator that helps to quickly open the airways, providing immediate relief of symptoms. Choice B, Methylprednisolone 100 mg IV, is a corticosteroid used for its anti-inflammatory effects but is not the initial medication for acute wheezing in an allergic reaction. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that can be used for prevention but is not the first choice for acute symptom relief. Choice D, Aminophylline 500 mg IV, is a bronchodilator with a narrow therapeutic window and more side effects compared to Albuterol, making it a less preferred option as the initial treatment.

3. What is the first medication to give to a patient experiencing wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn 20 mg via nebulizer
• C. Methylprednisolone 100 mg IV
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction due to its rapid action in opening airways. Cromolyn (Choice B) is used for prevention rather than acute treatment. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in allergic reactions.

4. What signs indicate increased intracranial pressure (IICP)?

• A. Restlessness, irritability, and confusion
• B. Sudden onset of seizures
• C. Bradycardia and altered pupil response
• D. Loss of consciousness

Correct answer: A

Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.

5. A nurse is providing discharge teaching to a client who is starting to take carbidopa/levodopa to treat Parkinson's disease. Which of the following instructions should the nurse include in the teaching?

• A. This medication can cause your urine to turn a dark color.
• B. Expect immediate relief after taking this medication.
• C. Take the medication with a high protein food.
• D. Skip a dose of the medication if you experience dizziness.

Correct answer: A

Rationale: The correct instruction to include in the teaching is that carbidopa/levodopa can cause the client's urine to turn a dark color, which is a harmless effect. It is crucial for the nurse to educate the client about this common side effect. Choice B is incorrect because immediate relief is not expected; therapeutic effects may take weeks to months. Choice C is incorrect as carbidopa/levodopa should be taken on an empty stomach to enhance absorption. Choice D is incorrect as the client should not skip doses without consulting their healthcare provider, even if they experience dizziness.
