1. What is a type of medication that helps to prevent blood clots by thinning the blood?

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

Correct answer: A

Rationale: Anticoagulants are medications specifically designed to prevent blood clots by thinning the blood. They work by interfering with the body's blood clotting process. Beta-blockers, ACE inhibitors, and calcium channel blockers are medications used for different purposes such as managing blood pressure, heart conditions, and regulating heart rhythm, respectively. However, they do not have the primary function of preventing blood clots like anticoagulants.

2. Which of the following is a chronic condition characterized by difficulty breathing due to airflow obstruction, commonly associated with long-term smoking?

• A. Chronic obstructive pulmonary disease (COPD)
• B. Asthma
• C. Pulmonary hypertension
• D. Bronchitis

Correct answer: A

Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic lung condition characterized by persistent airflow obstruction, commonly linked to long-term smoking. Choice B, Asthma, is a chronic condition characterized by reversible airflow obstruction and airway inflammation triggered by various factors like allergens and irritants. Choice C, Pulmonary hypertension, is a condition characterized by high blood pressure in the arteries of the lungs. Choice D, Bronchitis, is an inflammation of the bronchial tubes that may be acute or chronic, but it is not typically associated with long-term smoking like COPD.

3. Which order should the nurse question?

• A. The addition of a loop diuretic with digoxin.
• B. The addition of a beta blocker with digoxin.
• C. A digoxin dose of 0.125 mg per day.
• D. The addition of an ACE inhibitor with digoxin.

Correct answer: B

Rationale: The correct answer is B because adding a beta blocker to digoxin can potentiate the bradycardic effect of digoxin, leading to serious complications such as heart block. This combination requires caution as it can significantly slow down the heart rate. Choices A, C, and D are not the best options to question in this scenario. Loop diuretics are commonly used with digoxin, a digoxin dose of 0.125 mg per day is within the typical range, and ACE inhibitors are often prescribed alongside digoxin for managing heart conditions.

4. The nurse is caring for a client on digoxin. What is the most important assessment before administering this medication?

• A. Check the client’s heart rate.
• B. Check the client’s blood pressure.
• C. Check the client’s respiratory rate.
• D. Check the client’s oxygen saturation.

Correct answer: A

Rationale: The correct answer is to check the client’s heart rate before administering digoxin because one of the side effects of digoxin is bradycardia. Monitoring the heart rate is crucial to assess whether the client's heart rate is within the acceptable range before giving the medication. Checking the blood pressure (Choice B), respiratory rate (Choice C), or oxygen saturation (Choice D) are important assessments in general patient care, but they are not specifically related to the administration of digoxin.

5. What test measures the electrical activity of the heart over a period of time, typically 24 to 48 hours?

• A. Holter monitor
• B. Echocardiogram
• C. Stress test
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: The correct answer is A, Holter monitor. A Holter monitor is a portable device that records the electrical activity of the heart over a period of 24 to 48 hours. It is used to detect arrhythmias and other heart conditions. Choice B, Echocardiogram, is a test that uses sound waves to create images of the heart's structure and function, not focused on the electrical activity. Choice C, Stress test, evaluates the heart's function under stress but does not monitor electrical activity over an extended period. Choice D, Arterial blood gas (ABG), measures the levels of oxygen and carbon dioxide in the blood, unrelated to measuring the electrical activity of the heart over time.
