1. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?

• A. Warfarin
• B. Amlodipine
• C. Nitroglycerin
• D. Clopidogrel

Correct answer: A

Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.

2. A client asks the nurse to explain the difference between stable and unstable angina. What is the best response by the nurse?

• A. "Stable angina is predictable in its frequency, intensity, and duration. Unstable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?
• B. "Unstable angina is caused by spasms of the coronary arteries. Stable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?
• C. "Unstable angina is predictable in its frequency, intensity, and duration. Stable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?
• D. "Stable angina is caused by spasms of the coronary arteries. Unstable angina is when angina episodes become more frequent or severe, and occur during periods of rest."?

Correct answer: A

Rationale: Stable angina is typically triggered by physical exertion or emotional stress and is predictable in its frequency, intensity, and duration. In contrast, unstable angina is characterized by angina episodes that are unexpected, more severe, prolonged, and can occur at rest. Understanding these differences can help healthcare providers assess and manage angina episodes effectively, ensuring appropriate interventions are implemented promptly based on the type of angina present.

3. A client in a critical care unit is postoperative following a right pneumonectomy. After extubation from the ventilator, in which of the following positions should the client be placed?

• A. Prone
• B. On the nonoperative side
• C. Sims'
• D. Semi-Fowler's

Correct answer: D

Rationale: After a pneumonectomy, positioning the client in a semi-Fowler's position is crucial for optimal ventilation. This position helps improve lung expansion on the remaining side, facilitating better oxygenation and preventing complications like atelectasis. Placing the client prone, on the nonoperative side, or in Sims' position would not provide the same respiratory benefits post-pneumonectomy.

4. A client with HIV is starting therapy with zidovudine. The nurse should monitor the client for which of the following adverse effects of this medication?

• A. Fatigue
• B. Blurred vision
• C. Ringing in the ears
• D. Constipation

Correct answer: A

Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to cause bone marrow suppression, resulting in decreased production of red blood cells and subsequent fatigue.

5. Which of the following medications is a bronchodilator?

• A. Albuterol
• B. Omeprazole
• C. Ondansetron
• D. Senna

Correct answer: A

Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.
