What is a condition where the airways become swollen and produce extra mucus, making it difficult to breathe, often associated with COPD?
- A. Chronic bronchitis
- B. Pneumonia
- C. Emphysema
- D. Tuberculosis
Correct Answer: A
Rationale: Rationale:
1. Chronic bronchitis is characterized by inflammation of the airways leading to excess mucus production.
2. It is a common symptom of COPD, obstructing airflow and causing breathing difficulties.
3. Pneumonia, emphysema, and tuberculosis do not primarily involve airway inflammation and mucus production as seen in chronic bronchitis.

A patient with chronic heart failure is treated with hydrochlorothiazide, digoxin, and lisinopril. To prevent the risk of digitalis toxicity with these drugs, it is most important that the nurse monitor the patient's
- A. HR
- B. BP
- C. Potassium levels
- D. GI function
Correct Answer: C
Rationale: Hypokalemia is one of the most common causes of digitalis toxicity. When a patient is receiving potassium losing diuretics, such as hydrochlorothiazide and furosemide, it is essential to monitor the potassium level.
On what basis would the nurse suspect an MI?
- A. He has pale, cool, clammy skin
- B. He reports nausea and vomited once at home
- C. He says he is anxious and has a feeling of impending doom
- D. He reports he has had no relief of the pain with rest or position change
Correct Answer: D
Rationale: Persistent pain despite rest suggests MI.
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 A: Check the client's heart rate. Before administering digoxin, it is crucial to assess the client's heart rate as digoxin can cause bradycardia or arrhythmias. Monitoring the heart rate helps to determine if the client is at risk of experiencing these adverse effects. Checking blood pressure, respiratory rate, or oxygen saturation is important but not as crucial as assessing the heart rate when administering digoxin. Bradycardia is a common adverse effect of digoxin, so assessing the heart rate is the priority.
In developing a plan of care in relation to Mr. Robertson's diuretic therapy, it would be most important to
- A. Monitor vital signs frequently
- B. Give the Lasix with milk
- C. Observe for fluid overload
- D. Observe for signs of hypokalemia
Correct Answer: D
Rationale: Hypokalemia is a common side effect of diuretics.
This medication type is used to relax and widen blood vessels, improving blood flow and reducing blood pressure.
- A. Vasodilator
- B. Anticoagulant
- C. Diuretic
- D. Beta-blocker
Correct Answer: A
Rationale: The correct answer is A: Vasodilator. Vasodilators relax and widen blood vessels, leading to improved blood flow and decreased blood pressure. They work directly on the muscles in the walls of blood vessels. Anticoagulants (B) prevent blood clot formation, diuretics (C) increase urine production to reduce fluid buildup, and beta-blockers (D) reduce heart rate and blood pressure by blocking the effects of adrenaline. Therefore, only vasodilators directly target blood vessel relaxation and widening to improve blood flow and reduce blood pressure.
