Cardiovascular System Exam Questions And Answers
1. The client is on amiodarone and reports blurred vision. What is the nurse’s best response?
- A. Reassure the client that this is a common side effect.
- B. Instruct the client to report this symptom to the healthcare provider immediately.
- C. Advise the client to stop taking the medication.
- D. Discontinue the amiodarone immediately.
Correct answer: B
Rationale: Blurred vision is a potential side effect of amiodarone. Instructing the client to report this symptom to the healthcare provider immediately is the most appropriate response. Choice A is incorrect because although blurred vision can be a common side effect of amiodarone, it should not be dismissed without further evaluation. Choice C is incorrect as advising the client to stop taking the medication without consulting the healthcare provider can be dangerous and is not the first course of action. Choice D is too drastic as discontinuing the medication should be done under the guidance of a healthcare provider after proper evaluation.
2. What is a condition where the heart's electrical system malfunctions, leading to an irregular heartbeat or arrhythmia?
- A. Arrhythmia
- B. Bradycardia
- C. Tachycardia
- D. Ventricular fibrillation
Correct answer: A
Rationale: The correct answer is A, Arrhythmia. Arrhythmia refers to an irregular heartbeat caused by the malfunction of the heart's electrical system. Bradycardia (choice B) is a condition characterized by a slow heart rate, while Tachycardia (choice C) is a condition characterized by a fast heart rate. Ventricular fibrillation (choice D) is a life-threatening arrhythmia where the heart's lower chambers quiver erratically.
3. 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.
4. What is a chronic condition where the airways in the lungs become damaged and widened, leading to mucus buildup and frequent infections?
- A. Bronchiectasis
- B. Chronic bronchitis
- C. Pneumoconiosis
- D. Asthma
Correct answer: A
Rationale: Bronchiectasis is a chronic condition characterized by the damage and widening of the airways in the lungs, resulting in mucus accumulation and recurrent lung infections. Choice B, chronic bronchitis, involves inflammation of the bronchial tubes and excessive mucus production but does not specifically mention airway damage and widening. Choice C, pneumoconiosis, refers to lung diseases caused by inhalation of mineral dust particles, not airway damage and mucus buildup. Choice D, asthma, is a chronic condition characterized by airway inflammation and narrowing, leading to breathing difficulties, but it does not involve the widening and damage of the airways as seen in bronchiectasis.
5. After the AV node, the electrical impulse is then transmitted into the _________, and into the _________.
- A. Purkinje fibers, ventricles
- B. Atria, ventricles
- C. Bundle of His, Purkinje fibers
- D. Ventricles, Purkinje fibers
Correct answer: C
Rationale: The correct answer is C. After the AV node, the electrical impulse is transmitted to the Bundle of His and then to the Purkinje fibers. This sequence is crucial for the coordinated contraction of the ventricles. Choice A (Purkinje fibers, ventricles) is incorrect because the Purkinje fibers come after the Bundle of His in the sequence of electrical conduction. Choice B (Atria, ventricles) is incorrect because the impulse does not go back to the atria after passing through the AV node. Choice D (Ventricles, Purkinje fibers) is incorrect because the impulse first reaches the Bundle of His before spreading to the Purkinje fibers.
