Nursing Elites

1. Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?

• A. Pulmonary edema
• B. Pleurisy
• C. Pleural effusion
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A, Pulmonary edema. Pulmonary edema is a condition where fluid accumulates in the air sacs of the lungs, causing breathing difficulty. Pleurisy (choice B) is inflammation of the pleura causing chest pain. Pleural effusion (choice C) is the buildup of excess fluid in the pleural space, the area between the layers of tissue that line the lungs and chest cavity. Pneumothorax (choice D) is the presence of air in the pleural space, which can cause a lung to collapse.

2. The client is on hydrochlorothiazide and digoxin. What effect can the nurse expect?

• A. Hydrochlorothiazide increases digoxin levels.
• B. Hydrochlorothiazide decreases digoxin levels.
• C. Hydrochlorothiazide decreases potassium, increasing the risk of digoxin toxicity.
• D. Digoxin can increase the effectiveness of hydrochlorothiazide.

Correct answer: C

Rationale: The correct answer is C. Hydrochlorothiazide is a diuretic that can decrease potassium levels, which in turn can increase the risk of digoxin toxicity. Digoxin typically doesn't impact hydrochlorothiazide levels or effectiveness, making choices A, B, and D incorrect. Choice A stating that hydrochlorothiazide increases digoxin levels is inaccurate. Choice B suggesting that hydrochlorothiazide decreases digoxin levels is also incorrect. Choice D, stating that digoxin can increase the effectiveness of hydrochlorothiazide, is not a typical interaction seen between these medications.

3. What is a condition where the heart beats with an irregular or abnormal rhythm?

• A. Arrhythmia
• B. Hypertension
• C. Tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Arrhythmia is the correct answer because it refers to an irregular or abnormal heart rhythm, which can cause the heart to beat too fast, too slow, or erratically. Hypertension (choice B) is high blood pressure and not directly related to irregular heart rhythm. Tachycardia (choice C) is a condition where the heart beats too quickly, not necessarily irregularly. Bradycardia (choice D) is a condition where the heart beats too slowly, not necessarily irregularly. Therefore, only arrhythmia (choice A) fits the description provided in the question.

4. What procedure involves using a catheter to create a small scar in the heart tissue to block abnormal electrical signals and restore normal heart rhythm?

• A. Catheter ablation
• B. Angioplasty
• C. Stent placement
• D. Valve replacement

Correct answer: A

Rationale: Catheter ablation is the correct answer. During catheter ablation, a catheter is used to create a small scar in the heart tissue to block abnormal electrical signals, thereby restoring a normal heart rhythm. Choices B, C, and D are incorrect because angioplasty is a procedure to widen narrowed or obstructed arteries, stent placement involves inserting a mesh tube to support a weak artery, and valve replacement is the surgical procedure of replacing a heart valve, none of which match the description provided in the question.

5. What is the term for inflammation of the bronchial tubes, often leading to a persistent cough and mucus production?

• A. Bronchitis
• B. Asthma
• C. Pneumonia
• D. Cystic fibrosis

Correct answer: A

Rationale: The correct answer is 'Bronchitis.' Bronchitis refers to the inflammation of the bronchial tubes, which can be acute or chronic, leading to symptoms like coughing and increased mucus production. Choice B, 'Asthma,' is a chronic condition characterized by inflammation and narrowing of the airways, often causing wheezing and shortness of breath. Choice C, 'Pneumonia,' is an infection that inflames air sacs in one or both lungs, leading to symptoms like fever, cough, and difficulty breathing. Choice D, 'Cystic fibrosis,' is a genetic disorder that affects the lungs and digestive system, causing mucus buildup and respiratory issues.
