Nursing Elites

1. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?

• A. Hypokalemia
• B. Hypernatremia
• C. Hypochloremia
• D. Hypercalcemia

Correct answer: A

Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.

2. The nurse is assisting in the care of a client with a history of chronic obstructive pulmonary disease (COPD) who is on oxygen therapy. Which action should the nurse take to ensure the client's safety?

• A. Set the oxygen flow rate to 4 liters per minute.
• B. Remove oxygen while the client is eating.
• C. Ensure the client wears a nasal cannula instead of a face mask.
• D. Maintain the oxygen flow rate at the lowest level that relieves hypoxia.

Correct answer: D

Rationale: For clients with COPD, too much oxygen can suppress their drive to breathe, leading to hypoventilation. Therefore, the nurse should maintain the oxygen flow rate at the lowest level that relieves hypoxia to prevent complications while ensuring adequate oxygenation. Setting the oxygen flow rate too high (Choice A) can be detrimental for the client with COPD. Removing oxygen while the client is eating (Choice B) can compromise oxygenation, which is essential even during meals. While nasal cannulas are commonly used, the choice of oxygen delivery device depends on the client's needs; there may be situations where a face mask (Choice C) is more appropriate.

3. The healthcare provider notes this rhythm on the client's cardiac monitor. The healthcare provider next reports that the client is experiencing which heart rhythm?

• A. Normal sinus
• B. Atrial fibrillation
• C. Sinus bradycardia
• D. Ventricular fibrillation

Correct answer: B

Rationale: The correct answer is B, Atrial fibrillation. Atrial fibrillation is characterized by an irregular and often rapid heart rate, which can lead to poor blood flow due to ineffective contractions of the atria. Sinus bradycardia (Choice C) is a regular but slow heart rhythm originating from the sinus node. Normal sinus rhythm (Choice A) refers to a regular heartbeat originating from the sinus node. Ventricular fibrillation (Choice D) is a life-threatening arrhythmia characterized by rapid, uncoordinated contractions of the ventricles.

4. The healthcare provider is teaching a client with hypertension about lifestyle modifications. Which recommendation should the healthcare provider include?

• A. Limit alcohol consumption to one drink per day.
• B. Increase sodium intake to maintain blood pressure.
• C. Exercise vigorously for at least 30 minutes daily.
• D. Avoid high potassium foods like bananas.

Correct answer: A

Rationale: Limiting alcohol intake is an essential lifestyle modification recommended for managing hypertension. Excessive alcohol consumption can raise blood pressure, so limiting it to one drink per day is beneficial in controlling hypertension. Alcohol moderation is a key part of a heart-healthy lifestyle for individuals with high blood pressure. Choice B is incorrect because increasing sodium intake can actually worsen hypertension by retaining water and increasing blood pressure. Choice C is incorrect because while exercise is important for overall health, moderate-intensity exercise is recommended for individuals with hypertension to avoid excessive strain on the heart. Choice D is incorrect because high potassium foods like bananas are actually beneficial for individuals with hypertension as they can help lower blood pressure.

5. When reinforcing dietary instructions to a client with coronary artery disease prescribed a low-fat, low-cholesterol diet, which food item should the nurse advise the client to choose?

• A. Whole milk
• B. Grilled salmon
• C. Fried chicken
• D. Bacon and eggs

Correct answer: B

Rationale: Grilled salmon is the correct choice for a client with coronary artery disease on a low-fat, low-cholesterol diet because it is low in saturated fat and high in omega-3 fatty acids, which are beneficial for heart health. Whole milk, fried chicken, and bacon and eggs are higher in saturated fats and cholesterol, making them less suitable choices for this client. Whole milk is high in saturated fat, while fried chicken and bacon and eggs are sources of both saturated fat and cholesterol, which can negatively impact heart health in clients with coronary artery disease.
