1. Which of the following is a type of heart attack that occurs when the blood supply to part of the heart muscle is severely reduced or stopped?
- A. Myocardial infarction
- B. Angina
- C. Stroke
- D. Congestive heart failure
Correct answer: A
Rationale: The correct answer is A: Myocardial infarction. Myocardial infarction, commonly known as a heart attack, occurs when the blood supply to part of the heart muscle is severely reduced or stopped, leading to tissue damage or death. Angina (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood. Stroke (choice C) is a condition where the blood supply to the brain is interrupted or reduced. Congestive heart failure (choice D) is a chronic condition where the heart muscle doesn't pump blood as well as it should.
2. Which of the following is a chronic inflammatory disease of the airways that causes episodes of wheezing, breathlessness, chest tightness, and coughing?
- A. Asthma
- B. Bronchitis
- C. Pneumonia
- D. Emphysema
Correct answer: A
Rationale: Asthma is the correct answer. It is a chronic inflammatory disease of the airways characterized by episodes of wheezing, breathlessness, chest tightness, and coughing. These symptoms are often triggered by allergens or exercise. Bronchitis is an inflammation of the bronchial tubes, but it is not typically chronic or involve the same triggers as asthma. Pneumonia is an infection of the lungs, and emphysema is a type of chronic obstructive pulmonary disease (COPD) often caused by smoking.
3. What is a condition where the lung's alveoli are permanently enlarged and damaged, leading to shortness of breath?
- A. Emphysema
- B. Bronchitis
- C. Atelectasis
- D. Pulmonary fibrosis
Correct answer: A
Rationale: Emphysema is the correct answer. It is a chronic lung condition characterized by the permanent enlargement and damage of the alveoli, leading to shortness of breath and impaired oxygen exchange. Bronchitis is the inflammation of the bronchial tubes, not specifically related to alveolar damage. Atelectasis is the collapse of lung tissue, not enlargement. Pulmonary fibrosis involves scarring and thickening of lung tissue, different from the alveolar damage seen in emphysema.
4. 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.
5. The client on digoxin has a potassium level of 3.0 mEq/L. What is the nurse’s priority action?
- A. Administer a potassium supplement
- B. Hold the digoxin and notify the healthcare provider
- C. Continue the current digoxin dose
- D. Administer Digibind
Correct answer: B
Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 3.0 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac arrhythmias. Administering a potassium supplement (choice A) without healthcare provider guidance can worsen the situation. Continuing the current digoxin dose (choice C) can further increase the risk of toxicity. Administering Digibind (choice D) is used in severe cases of digoxin toxicity, not for addressing low potassium levels.
