Nursing Elites

1. Which test uses sound waves to create images of the heart, allowing doctors to assess its structure and function?

• A. Echocardiogram
• B. MRI
• C. CT scan
• D. X-ray

Correct answer: A

Rationale: The correct answer is A: Echocardiogram. An echocardiogram is a test that uses sound waves to create images of the heart, enabling doctors to assess its structure and function. This imaging technique is particularly useful in detecting abnormalities such as valve disease. Choices B, C, and D are incorrect because MRI, CT scans, and X-rays use different imaging technologies that do not rely on sound waves to visualize the heart.

2. Which chronic respiratory condition is characterized by the narrowing and inflammation of the airways, leading to difficulty breathing?

• A. Asthma
• B. COPD
• C. Bronchitis
• D. Pneumonia

Correct answer: A

Rationale: Asthma is the correct answer. It is a chronic respiratory condition where the airways become inflamed and narrowed, leading to episodes of wheezing, breathlessness, chest tightness, and coughing. Asthma is characterized by reversible airflow obstruction, differentiating it from COPD, which involves irreversible airflow limitation. Bronchitis is an inflammation of the bronchial tubes without the same reversible airflow obstruction seen in asthma. Pneumonia is an infection of the lung tissue and does not involve chronic inflammation and narrowing of the airways like asthma.

3. What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?

• A. Corticosteroid
• B. Bronchodilator
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Corticosteroid. Corticosteroids are medications that work by reducing inflammation in the airways, helping to prevent asthma attacks and manage chronic respiratory conditions. Bronchodilators (choice B) work by relaxing the muscles around the airways to make breathing easier, but they do not primarily target inflammation. Antihistamines (choice C) are used to treat allergic reactions and do not directly target airway inflammation. Mucolytics (choice D) help to break down and thin mucus in the airways but do not reduce inflammation.

4. The client on nitroglycerin patches reports dizziness when standing up. What is the nurse’s best response?

• A. Advise the client to rise slowly to prevent dizziness.
• B. Instruct the client to discontinue the nitroglycerin patches.
• C. Encourage the client to rest and avoid physical activity.
• D. Suggest the client take an over-the-counter antiemetic.

Correct answer: A

Rationale: The correct answer is to advise the client to rise slowly to prevent dizziness. Dizziness when standing up can be a sign of orthostatic hypotension, a common side effect of nitroglycerin. Rising slowly can help minimize this symptom. Instructing the client to discontinue the nitroglycerin patches (Choice B) is not appropriate without consulting a healthcare provider as sudden discontinuation can lead to adverse effects. Encouraging the client to rest and avoid physical activity (Choice C) does not address the specific issue of orthostatic hypotension. Suggesting the client take an over-the-counter antiemetic (Choice D) is not indicated for dizziness related to orthostatic hypotension.

5. 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.
