Nursing Elites

1. Which type of lung cancer is strongly associated with exposure to asbestos?

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

Correct answer: A

Rationale: The correct answer is Mesothelioma. This type of lung cancer is indeed strongly associated with exposure to asbestos, affecting the lining of the lungs or abdomen. Adenocarcinoma, Squamous cell carcinoma, and Small cell lung cancer are not primarily linked to asbestos exposure, making them incorrect choices for this question.

2. What type of medication is used to reduce high blood pressure by relaxing the blood vessels?

• A. Calcium channel blocker
• B. Beta-blocker
• C. ACE inhibitor
• D. Diuretic

Correct answer: A

Rationale: Calcium channel blockers are medications that reduce high blood pressure by relaxing the blood vessels, facilitating easier blood flow through the vessels. Beta-blockers work by reducing the heart rate and the heart's workload. ACE inhibitors help relax blood vessels by blocking the production of a chemical that narrows blood vessels. Diuretics help the body get rid of excess sodium and water to lower blood pressure, but they do not directly relax blood vessels like calcium channel blockers do.

3. The client on nitroglycerin complains of a headache. What is the most appropriate response by the nurse?

• A. Administer acetaminophen as prescribed for the headache.
• B. Hold the next dose of nitroglycerin.
• C. Discontinue the nitroglycerin immediately.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: The correct response is to administer acetaminophen as prescribed for the headache. Headaches are a common side effect of nitroglycerin due to vasodilation. Administering acetaminophen can help relieve the headache. Holding the next dose of nitroglycerin (Choice B) may not address the current headache, and discontinuing nitroglycerin immediately (Choice C) without healthcare provider guidance can be dangerous due to the potential for rebound hypertension. Notifying the healthcare provider immediately (Choice D) is not necessary for a common side effect like a headache, and the nurse can manage this symptom independently.

4. The client is on digoxin and has severe digoxin toxicity. What is the nursing priority action?

• A. Check the potassium level.
• B. Give Digibind as an antidote.
• C. Change the dosing of digoxin to every other day.
• D. Administer a potassium supplement to decrease digoxin toxicity.

Correct answer: B

Rationale: The correct answer is to give Digibind as an antidote in cases of severe digoxin toxicity. Digibind works by binding to digoxin and preventing it from causing further harm. Checking the potassium level (choice A) is important but not the priority when the client has severe toxicity. Changing the dosing to every other day (choice C) is not appropriate in the setting of severe toxicity where immediate action is required. Giving a potassium supplement (choice D) may be needed eventually, but the priority is to administer Digibind to counteract the toxic effects of digoxin.

5. What is the condition where a blood clot blocks an artery in the lungs, causing shortness of breath, chest pain, and other symptoms?

• A. Pulmonary embolism
• B. Pneumothorax
• C. Pleural effusion
• D. Aneurysm

Correct answer: A

Rationale: The correct answer is Pulmonary embolism. Pulmonary embolism occurs when a blood clot blocks an artery in the lungs, leading to symptoms like shortness of breath and chest pain. This condition is life-threatening and requires prompt treatment. Choices B, C, and D are incorrect as they refer to different medical conditions: Pneumothorax is a collapsed lung, Pleural effusion is an abnormal accumulation of fluid around the lungs, and an Aneurysm is a bulge in a blood vessel.
