Nursing Elites

1. What medication should be administered first for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn via nebulizer
• C. Methylprednisolone IV
• D. Aminophylline 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 quickly opens the airways by relaxing the muscles around the airways. Cromolyn (choice B) is used more for prevention rather than immediate relief of symptoms. Methylprednisolone (choice C) and Aminophylline (choice D) are not the first-line treatments for acute wheezing due to an allergic reaction.

2. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

3. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

• A. Defibrillation
• B. Synchronized cardioversion
• C. Pacing
• D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.

4. 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.

5. 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.
