1. Which type of medication is used to reduce the workload on the heart by slowing down the heart rate and lowering blood pressure?

• A. Beta-blocker
• B. ACE inhibitor
• C. Calcium channel blocker
• D. Diuretic

Correct answer: A

Rationale: The correct answer is A: Beta-blocker. Beta-blockers are medications that reduce the workload on the heart by slowing down the heart rate and lowering blood pressure. They are commonly used in the treatment of heart conditions such as hypertension and heart failure. ACE inhibitors (B) work by dilating blood vessels to reduce blood pressure, calcium channel blockers (C) prevent calcium from entering the heart muscle and blood vessel walls, and diuretics (D) help the body get rid of excess salt and water by increasing urine production.

2. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?

• A. Peripheral artery disease
• B. Raynaud's disease
• C. Varicose veins
• D. Pulmonary embolism

Correct answer: A

Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.

3. What condition is characterized by narrowed or blocked arteries in the legs or arms, leading to pain and mobility issues?

• A. Peripheral artery disease
• B. Atherosclerosis
• C. Raynaud's disease
• D. Varicose veins

Correct answer: A

Rationale: The correct answer is A: Peripheral artery disease (PAD). PAD is a condition where the arteries in the legs or arms become narrowed or blocked, leading to pain and mobility issues. Choice B, Atherosclerosis, refers to the buildup of fats, cholesterol, and other substances in and on the artery walls, not specifically the narrowing or blockage in the extremities. Choice C, Raynaud's disease, is characterized by reduced blood flow to the extremities, leading to coldness, numbness, and color changes in the skin, but it is not primarily about narrowed or blocked arteries. Choice D, Varicose veins, involves enlarged, twisted veins usually in the legs, but it is not related to narrowed or blocked arteries causing pain and mobility issues.

4. 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.

5. The client is receiving digoxin and has a potassium level of 2.8 mEq/L. What is the nurse’s priority action?

• A. Hold the digoxin and notify the healthcare provider.
• B. Increase the dose of digoxin.
• C. Continue the current dose of digoxin.
• D. Administer potassium supplements.

Correct answer: A

Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 2.8 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Holding the medication and informing the healthcare provider is crucial to prevent adverse effects. Choice B is incorrect because increasing the dose of digoxin would further raise the risk of toxicity. Choice C is incorrect as continuing the current dose could exacerbate the toxicity risk. Choice D is incorrect because administering potassium supplements alone is not sufficient to address the potential digoxin toxicity; the first step should be to hold the digoxin and seek further guidance.
