Cardiovascular System Exam Questions Pdf
1. 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.
2. The nurse is giving nitroglycerin sublingually for chest pain. What is the most important instruction to give to the client?
- A. Place the tablet under the tongue and let it dissolve completely.
- B. Swallow the tablet whole with a glass of water.
- C. Chew the tablet and then swallow it.
- D. Take one tablet every 5 minutes until pain is relieved.
Correct answer: A
Rationale: The correct answer is A. The tablet should be placed under the tongue and allowed to dissolve completely to ensure rapid absorption. This route of administration allows the medication to be quickly absorbed into the bloodstream. Choice B is incorrect because nitroglycerin is meant to be absorbed sublingually, not swallowed. Choice C is incorrect as chewing the tablet can cause the medication to be rapidly absorbed, leading to adverse effects like a drop in blood pressure. Choice D is incorrect because the client should take only one tablet every 5 minutes up to a maximum of three tablets for chest pain relief.
3. What is a condition where the lung's air sacs (alveoli) are damaged and enlarged, leading to breathlessness?
- A. Emphysema
- B. Chronic bronchitis
- C. Asthma
- D. Pulmonary fibrosis
Correct answer: A
Rationale: Emphysema is the correct answer. It is a condition where the air sacs in the lungs are damaged and enlarged, leading to breathlessness. Chronic bronchitis is characterized by inflammation of the bronchial tubes, not the alveoli. Asthma involves airway inflammation and constriction, not alveolar damage. Pulmonary fibrosis is a condition where lung tissue becomes thickened and scarred, different from the alveolar damage seen in emphysema.
4. 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.
5. What is the condition where the lungs become filled with fluid, often due to heart failure, making it difficult to breathe?
- A. Pulmonary edema
- B. Pleural effusion
- C. Pulmonary hypertension
- D. Pneumothorax
Correct answer: A
Rationale: Pulmonary edema is the correct answer. It occurs when fluid fills the lungs, usually due to heart failure, leading to breathing difficulties. Pleural effusion is the accumulation of fluid around the lungs, not inside. Pulmonary hypertension is high blood pressure in the arteries of the lungs, and pneumothorax is the presence of air between the lung and chest wall.
