- A. A 26-year-old with heart failure caused by congenital mitral stenosis who is scheduled for balloon valvuloplasty later today.
- B. A 45-year-old with constrictive cardiomyopathy who developed acute dyspnea and agitation about 1 hour before the shift change.
- C. A 56-year-old who had a coronary angioplasty and stent placement yesterday and has complained of occasional chest pain since the procedure.
- D. A 77-year-old who transferred from intensive care 2 days ago after coronary artery bypass grafting and has a temperature of 100.6°F.
Correct Answer: B
Rationale: Acute dyspnea and agitation suggest worsening heart failure or another urgent condition.

Which of the following is a chronic respiratory disease characterized by the irreversible obstruction of airflow?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary edema
- D. Bronchiectasis
Correct Answer: A
Rationale: The correct answer is A: Chronic obstructive pulmonary disease (COPD). COPD is a chronic respiratory disease characterized by irreversible airflow obstruction due to conditions such as emphysema and chronic bronchitis. This is because COPD causes damage to the airways and alveoli, leading to decreased airflow. Asthma (B) is a chronic inflammatory disease with reversible airflow obstruction. Pulmonary edema (C) is caused by fluid accumulation in the lungs, leading to difficulty in breathing but is not characterized by irreversible airflow obstruction. Bronchiectasis (D) involves the widening and scarring of the airways, leading to recurrent infections, but it is not specifically characterized by irreversible airflow obstruction.
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: The addition of a beta blocker with digoxin. When combined, beta blockers can enhance the effects of digoxin, leading to an increased risk of bradycardia and heart block. This combination can also exacerbate digoxin toxicity. Therefore, the nurse should question the addition of a beta blocker with digoxin to prevent potential adverse effects.
Incorrect choices:
A: The addition of a loop diuretic with digoxin - Loop diuretics may lead to hypokalemia, which can increase the risk of digoxin toxicity.
C: A digoxin dose of 0.125 mg per day - This is within the recommended dose range for digoxin and does not pose a significant concern.
D: The addition of an ACE inhibitor with digoxin - ACE inhibitors are commonly used in combination with digoxin and do not typically interact negatively.
What is a blood clot that forms in a vein, often in the legs, and can cause serious complications if it travels to the lungs?
- A. Deep vein thrombosis (DVT)
- B. Pulmonary embolism
- C. Varicose veins
- D. Atherosclerosis
Correct Answer: A
Rationale: The correct answer is A: Deep vein thrombosis (DVT). DVT is a blood clot that forms in a deep vein, commonly in the legs. It can lead to serious complications if the clot dislodges and travels to the lungs, causing a pulmonary embolism. Varicose veins (C) are enlarged, twisted veins near the surface of the skin, not involving deep veins. Atherosclerosis (D) is the build-up of plaque in arteries, not related to vein clot formation. Pulmonary embolism (B) is a complication of DVT, not the initial clot formation in a vein.
