Nursing Elites

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. A nurse is reviewing the medical record of a client who has unstable angina. Which of the following findings should the nurse report to the provider?

• A. Breath sounds
• B. Temperature
• C. Blood pressure
• D. Creatine kinase

Correct answer: A

Rationale: The correct answer is A: Breath sounds. When caring for a client with unstable angina, changes in breath sounds could indicate left ventricular failure and pulmonary edema due to decreased cardiac output and reduced cardiac perfusion. Reporting any abnormalities in breath sounds promptly to the provider is crucial to prevent further complications. Choices B, C, and D are not directly related to the immediate management of unstable angina. Temperature, blood pressure, and creatine kinase levels are important parameters to monitor but are not the priority in this situation.

3. A patient is receiving discharge instructions for GERD. Which of the following statements by the patient demonstrates an understanding of the teaching?

• A. I should take my medication with orange juice.
• B. Having a bedtime snack will prevent heartburn.
• C. I will lie down after meals.
• D. I will limit activities that require bending at the waist.

Correct answer: D

Rationale: The correct answer is D. Patients with GERD should avoid activities that increase intra-abdominal pressure, such as bending at the waist, as this can lead to reflux. Choice A is incorrect because medications for GERD are usually taken with water, not citrus juices. Choice B is incorrect as having a bedtime snack can worsen GERD symptoms. Choice C is incorrect because lying down after meals can also exacerbate reflux due to the effects of gravity.

4. What is the expected finding in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized swelling and redness
• C. Numbness and tingling
• D. Fever and infection

Correct answer: A

Rationale: In a patient with compartment syndrome, the expected finding includes unrelieved pain, pallor, and pulselessness. These are classic signs of compartment syndrome and indicate compromised blood flow and tissue perfusion, necessitating urgent intervention. Choices B, C, and D are incorrect because localized swelling and redness, numbness and tingling, as well as fever and infection, are not typical findings associated with compartment syndrome.

5. What intervention should be done if continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Replace the chest tube system
• C. Clamp the chest tube
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate intervention is to tighten the connections of the chest tube system. This step helps address an air leak in the system, which could compromise its effectiveness. Choice B (Replace the chest tube system) is not the initial step and may be unnecessary if the issue can be resolved by tightening connections. Choice C (Clamp the chest tube) is incorrect as clamping the chest tube could lead to a dangerous increase in pressure within the system. Choice D (Continue monitoring the chest tube) is also not the best immediate action to take when continuous bubbling is present, as prompt intervention is needed to prevent complications.
