1. What ECG changes are seen with hyperkalemia?

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

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

2. 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.

3. What adverse effect might occur in a patient receiving radiation after a mastectomy?

• A. Seizures
• B. JVD and fatigue
• C. SOB and JVD
• D. S3 heart sound

Correct answer: D

Rationale: The correct adverse effect that might occur in a patient receiving radiation after a mastectomy is the development of an S3 heart sound. This can result from decreased pumping ability following mastectomy and radiation treatment. Choice A, seizures, is incorrect as seizures are not a common adverse effect of radiation after a mastectomy. Choice B, JVD and fatigue, is incorrect as while fatigue can be a common side effect, JVD (Jugular Venous Distention) is not typically associated with radiation after a mastectomy. Choice C, SOB (Shortness of Breath) and JVD, is incorrect as while shortness of breath can occur, JVD is not a typical adverse effect of radiation post-mastectomy.

4. A nurse is providing teaching to a client who was newly diagnosed with nephrotic syndrome. Which of the following statements should indicate to the nurse that the client understands the teaching?

• A. I can expect swelling in my hands and on my face.
• B. The amount of protein in my blood is high.
• C. I might have some pain and gas in my stomach from this condition.
• D. I will use a soft bristle toothbrush to prevent bleeding gums.

Correct answer: A

Rationale: The correct answer is A. Nephrotic syndrome leads to edema, especially of the face and dependent areas, due to the loss of protein in the urine. Choice B is incorrect because nephrotic syndrome leads to protein loss in the urine, not an increase in blood protein levels. Choice C is incorrect as stomach pain and gas are not typical symptoms of nephrotic syndrome. Choice D is incorrect as using a soft bristle toothbrush is not directly related to the manifestations of nephrotic syndrome.

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

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

Correct answer: A

Rationale: In a patient with ventricular tachycardia and a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat unstable tachyarrhythmias like ventricular tachycardia with a pulse. Choice B, defibrillation, is used for pulseless ventricular tachycardia or ventricular fibrillation. Choice C, medication administration, may not provide immediate correction for unstable ventricular tachycardia. Choice D, pacing, is not the first-line treatment for ventricular tachycardia with a pulse.
