Nursing Elites

1. What is the procedure where a device is used to shock the heart back into a normal rhythm during a life-threatening arrhythmia?

• A. Defibrillation
• B. Cardioversion
• C. Echocardiogram
• D. Ablation

Correct answer: A

Rationale: The correct answer is A, Defibrillation. Defibrillation is the procedure of using a device to deliver an electric shock to the heart during life-threatening arrhythmias like ventricular fibrillation or ventricular tachycardia to restore a normal rhythm. Choice B, Cardioversion, is similar but is typically used for less severe arrhythmias. Choice C, Echocardiogram, is a diagnostic test that uses sound waves to create images of the heart. Choice D, Ablation, is a procedure to treat certain types of arrhythmias by scarring or destroying tissue that triggers abnormal electrical signals.

2. Which type of lung cancer begins in the cells lining the bronchi and bronchioles?

• A. Adenocarcinoma
• B. Small cell lung cancer
• C. Squamous cell carcinoma
• D. Mesothelioma

Correct answer: A

Rationale: Adenocarcinoma is the correct answer because it is a type of lung cancer that originates in the cells lining the bronchi and bronchioles. Adenocarcinoma is one of the most common types of lung cancer, often found in non-smokers and more frequently in women. Small cell lung cancer (Choice B) typically starts in the bronchi, but it is characterized by its rapid growth and tendency to spread quickly. Squamous cell carcinoma (Choice C) usually begins in the squamous cells lining the bronchi and is strongly associated with smoking. Mesothelioma (Choice D) is a cancer that affects the lining of certain organs like the lungs, often caused by asbestos exposure, but it does not specifically start in the cells lining the bronchi and bronchioles.

3. What is a condition where the blood flow to the brain is temporarily blocked, often referred to as a mini-stroke?

• A. Transient ischemic attack (TIA)
• B. Stroke
• C. Aneurysm
• D. Myocardial infarction

Correct answer: A

Rationale: A transient ischemic attack (TIA) is the correct answer. A TIA is often referred to as a mini-stroke because it is caused by a temporary blockage of blood flow to the brain. This blockage resolves on its own, typically within minutes to hours, leading to temporary symptoms similar to a stroke. Option B, 'Stroke,' is incorrect because a stroke involves a more prolonged interruption of blood flow to the brain. Option C, 'Aneurysm,' is incorrect as it is a bulge in a blood vessel that can rupture and cause bleeding, not a temporary blockage of blood flow. Option D, 'Myocardial infarction,' is also incorrect as it refers to a heart attack, not a condition involving the brain's blood flow.

4. Which of the following is a rare genetic disorder that affects the lungs, liver, and skin, causing the buildup of a specific protein that damages organs?

• A. Alpha-1 antitrypsin deficiency
• B. Cystic fibrosis
• C. Wegener's granulomatosis
• D. Marfan syndrome

Correct answer: A

Rationale: The correct answer is Alpha-1 antitrypsin deficiency. This disorder leads to the accumulation of a specific protein that can harm the lungs, liver, and skin. Choice B, Cystic fibrosis, is incorrect because it primarily affects the lungs and digestive system due to a defective gene. Choice C, Wegener's granulomatosis, is an autoimmune disease that involves inflammation of blood vessels, not protein buildup. Choice D, Marfan syndrome, is a connective tissue disorder impacting the heart, blood vessels, bones, and eyes, but not involving protein accumulation that damages organs.

5. The nurse is caring for a client on amiodarone. What adverse effect is the nurse most concerned about?

• A. Pulmonary toxicity
• B. Liver toxicity
• C. Thyroid dysfunction
• D. Renal dysfunction

Correct answer: A

Rationale: The correct answer is A, Pulmonary toxicity. Amiodarone is known to cause pulmonary toxicity, which can be serious and even fatal in some cases. This adverse effect includes interstitial pneumonitis, pulmonary fibrosis, and acute respiratory distress syndrome. Monitoring for symptoms such as cough, dyspnea, and fever is crucial. Choices B, Liver toxicity, C, Thyroid dysfunction, and D, Renal dysfunction, are incorrect because while amiodarone can also affect the liver, thyroid, and kidneys, the most concerning adverse effect that requires immediate attention and monitoring is pulmonary toxicity.
