1. What is this surgical procedure that restores blood flow to the heart by diverting blood around a blocked artery?

• A. Coronary artery bypass graft (CABG)
• B. Angioplasty
• C. Stent placement
• D. Valve replacement

Correct answer: A

Rationale: The correct answer is A, Coronary artery bypass graft (CABG), which is a surgical procedure to improve blood flow to the heart by redirecting blood around blocked or narrowed arteries. This procedure is specifically designed to bypass blocked coronary arteries, allowing blood to flow more freely to the heart muscle. Choices B, C, and D are incorrect because angioplasty involves opening up narrowed or blocked blood vessels, stent placement involves inserting a mesh tube to keep arteries open, and valve replacement involves replacing a damaged heart valve - none of which directly address diverting blood flow around a blocked artery.

2. The client on a beta blocker has a blood pressure of 88/58 mm Hg. What is the nurse’s priority action?

• A. Hold the beta blocker and notify the healthcare provider.
• B. Administer the beta blocker as ordered.
• C. Increase the dose of the beta blocker.
• D. Continue to monitor the client and reassess in 30 minutes.

Correct answer: A

Rationale: The correct action for the nurse to take when a client on a beta blocker presents with a blood pressure of 88/58 mm Hg is to hold the beta blocker and notify the healthcare provider. Beta blockers can further decrease blood pressure, which is already low in this case. Administering the beta blocker as ordered (Choice B) would exacerbate the hypotension. Increasing the dose of the beta blocker (Choice C) would be inappropriate and unsafe given the low blood pressure. Continuing to monitor the client and reassessing in 30 minutes (Choice D) could lead to a delay in necessary intervention. Therefore, the priority is to hold the medication and seek guidance from the healthcare provider.

3. What is a condition where the lung's alveoli are permanently enlarged and damaged, leading to shortness of breath?

• A. Emphysema
• B. Bronchitis
• C. Atelectasis
• D. Pulmonary fibrosis

Correct answer: A

Rationale: Emphysema is the correct answer. It is a chronic lung condition characterized by the permanent enlargement and damage of the alveoli, leading to shortness of breath and impaired oxygen exchange. Bronchitis is the inflammation of the bronchial tubes, not specifically related to alveolar damage. Atelectasis is the collapse of lung tissue, not enlargement. Pulmonary fibrosis involves scarring and thickening of lung tissue, different from the alveolar damage seen in emphysema.

4. Which condition is characterized by a chronic cough that produces mucus, often caused by long-term exposure to irritants?

• A. Chronic bronchitis
• B. Tuberculosis
• C. Asthma
• D. Sinusitis

Correct answer: A

Rationale: Chronic bronchitis is the correct answer. It is characterized by a long-term cough with mucus production, often caused by smoking or prolonged exposure to irritants. Tuberculosis (choice B) is a bacterial infection that primarily affects the lungs but does not usually present with a chronic cough as the main symptom. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to wheezing and shortness of breath, but it does not typically cause chronic mucus production. Sinusitis (choice D) is inflammation of the sinuses and presents with symptoms like facial pain, nasal congestion, and post-nasal drip, but not specifically a chronic cough with mucus production.

5. The healthcare provider is monitoring a client receiving lidocaine IV. What side effect is the healthcare provider most concerned about?

• A. Severe headache
• B. Nausea and vomiting
• C. Seizures
• D. Tremors

Correct answer: C

Rationale: Seizures are the most concerning side effect of lidocaine IV administration due to its potential to indicate lidocaine toxicity, which can lead to serious complications such as cardiovascular collapse. Headache, nausea, and tremors are not typically associated with lidocaine IV and are less concerning compared to seizures in this context.
