Nursing Elites

1. Which test measures the electrical activity of the heart and can detect arrhythmias and other heart conditions?

• A. Electrocardiogram (ECG or EKG)
• B. Chest X-ray
• C. MRI
• D. CT scan

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG or EKG). An electrocardiogram is a test that measures the electrical activity of the heart and can detect arrhythmias and other heart conditions by recording the heart's electrical impulses. Choices B, C, and D are incorrect because a chest X-ray is used to visualize the structures in the chest, an MRI (Magnetic Resonance Imaging) is used to provide detailed images of organs and tissues, and a CT scan (Computed Tomography) is a type of imaging that uses X-rays to create detailed cross-sectional images of the body.

2. What is the term for a blood clot blocking an artery in the lungs, leading to symptoms like shortness of breath and chest pain?

• A. Pulmonary embolism
• B. Deep vein thrombosis (DVT)
• C. Myocardial infarction
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A, pulmonary embolism. A pulmonary embolism occurs when a blood clot travels to the lungs and blocks an artery, causing symptoms like shortness of breath and chest pain. Choice B, deep vein thrombosis (DVT), involves a blood clot forming in a deep vein, usually in the legs. Choice C, myocardial infarction, refers to a heart attack due to blocked blood flow to the heart muscle. Choice D, pneumothorax, is a collapsed lung due to air leaking into the chest cavity.

3. A client on an ACE inhibitor reports a persistent cough. What is the nurse’s best response?

• A. Reassure the client that the cough is a common side effect and is usually not serious.
• B. Instruct the client to report the cough to the healthcare provider as it may require discontinuation of the medication.
• C. Advise the client to use a humidifier at night to relieve the cough.
• D. Suggest the client take an over-the-counter cough suppressant.

Correct answer: B

Rationale: The correct answer is B. A persistent cough in a client on an ACE inhibitor may indicate a serious side effect that requires discontinuation of the medication. Instructing the client to report the cough to the healthcare provider is essential for proper evaluation and management. Choice A is incorrect because simply reassuring the client may delay necessary action. Choice C is incorrect as using a humidifier may not address the underlying cause of the cough. Choice D is incorrect because taking a cough suppressant without healthcare provider guidance may mask symptoms without addressing the cause.

4. What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?

• A. Chronic bronchitis
• B. Emphysema
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: Chronic bronchitis is the correct answer because it is a long-term condition characterized by inflammation and narrowing of the bronchial tubes in the lungs, commonly triggered by smoking. Emphysema involves damage to the air sacs in the lungs, not specifically the bronchial tubes. Asthma is a condition of reversible airway obstruction usually due to allergies or other triggers, not solely smoking. Tuberculosis is a bacterial infection that primarily affects the lungs but is not directly related to inflammation and narrowing of the bronchial tubes.

5. The nurse is caring for a client with atrial fibrillation on dabigatran (Pradaxa). What is the most important instruction to give to the client?

• A. Take the medication with food to prevent stomach upset.
• B. Do not miss a dose and take it at the same time each day.
• C. Avoid consuming alcohol while on this medication.
• D. Monitor for signs of bleeding.

Correct answer: B

Rationale: The most important instruction to give to a client on dabigatran (Pradaxa) is not to miss a dose and take it at the same time each day. This is crucial for maintaining the anticoagulant effect of the medication. Choice A is not necessary as dabigatran does not need to be taken with food. Choice C is important but not as crucial as ensuring proper dosing. Choice D is also important but falls behind in priority compared to maintaining consistent dosing.
