Nursing Elites

1. What is the condition where the lungs become filled with fluid, often due to heart failure, making it difficult to breathe?

• A. Pulmonary edema
• B. Pleural effusion
• C. Pulmonary hypertension
• D. Pneumothorax

Correct answer: A

Rationale: Pulmonary edema is the correct answer. It occurs when fluid fills the lungs, usually due to heart failure, leading to breathing difficulties. Pleural effusion is the accumulation of fluid around the lungs, not inside. Pulmonary hypertension is high blood pressure in the arteries of the lungs, and pneumothorax is the presence of air between the lung and chest wall.

2. What is a condition where blood clots form in the deep veins, usually in the legs, and can travel to the lungs, causing serious complications?

• A. Deep vein thrombosis (DVT)
• B. Pulmonary embolism
• C. Varicose veins
• D. Peripheral artery disease

Correct answer: A

Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when blood clots form in the deep veins, usually in the legs, and these clots can potentially travel to the lungs, leading to a pulmonary embolism. Pulmonary embolism (choice B) is a serious complication that can result from untreated DVT. Varicose veins (choice C) and peripheral artery disease (choice D) are not directly related to the formation of blood clots in deep veins that can lead to pulmonary embolism.

3. The client is given an alpha agonist. What might it be used for?

• A. For hemostasis
• B. To dilate the arteries
• C. To dilate the veins
• D. To decrease afterload

Correct answer: A

Rationale: Alpha agonists are used for hemostasis to help control bleeding by constricting blood vessels, leading to decreased blood flow to the area. Choices B, C, and D are incorrect as alpha agonists do not typically dilate arteries, dilate veins, or decrease afterload.

4. Which artery supplies the right atrium, right ventricle, a portion of the septum, SA node, AV node, and inferior portion of the left ventricle?

• A. Right coronary artery
• B. Left circumflex artery
• C. Posterior descending artery
• D. Aortic artery

Correct answer: A

Rationale: The correct answer is the right coronary artery. It supplies essential areas of the heart, including the right atrium, right ventricle, a portion of the septum, SA node, AV node, and the inferior portion of the left ventricle. The left circumflex artery primarily supplies the left atrium and lateral wall of the left ventricle, not the mentioned areas. The posterior descending artery supplies the inferior wall of the left ventricle, not the right side. The aortic artery is a general term and does not specifically refer to an artery that supplies the mentioned areas.

5. The nurse is administering a beta blocker to a client with a heart rate of 50 bpm. What is the priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Decrease the dose of the beta blocker.
• D. Monitor the client’s heart rate and reassess in 30 minutes.

Correct answer: A

Rationale: The correct action is to hold the beta blocker and notify the healthcare provider. A heart rate of 50 bpm is already low, and beta blockers can further decrease the heart rate, potentially causing adverse effects like bradycardia or heart block. Administering the beta blocker as ordered (Choice B) can exacerbate the low heart rate. Decreasing the dose of the beta blocker (Choice C) may not be sufficient to address the potential harm. Monitoring the client’s heart rate and reassessing in 30 minutes (Choice D) may delay necessary interventions if the heart rate drops further. Therefore, the priority is to hold the medication and seek guidance from the healthcare provider.
