Nursing Elites

1. The nurse is preparing to administer a beta blocker to a client with hypertension. What is the priority assessment?

• 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 temperature.

Correct answer: B

Rationale: The correct answer is to check the client's blood pressure. Before administering a beta blocker to a client with hypertension, assessing the blood pressure is crucial because beta blockers can cause hypotension, potentially leading to adverse effects. Checking the heart rate may also be important but is secondary to monitoring the blood pressure in this scenario. Respiratory rate and temperature assessments are not directly related to assessing the client's response to a beta blocker in hypertension management, making choices C and D less relevant.

2. What test measures the electrical activity of the heart over a 24- or 48-hour period?

• A. Holter monitor
• B. Electrocardiogram
• C. Stress test
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Holter monitor. A Holter monitor is a portable device that continuously records the heart's electrical activity over 24 to 48 hours, aiding in the diagnosis of arrhythmias and other heart conditions. Choice B, an Electrocardiogram, provides a snapshot of the heart's electrical activity at a specific point in time, not over an extended period like a Holter monitor. Choice C, a Stress test, measures how the heart responds to physical activity and is not used for continuous monitoring of electrical activity. Choice D, a Chest X-ray, is used to visualize the structures of the chest, not to measure the heart's electrical activity.

3. The client is on amiodarone. What is the most important side effect to monitor for?

• A. Pulmonary toxicity
• B. Thyroid dysfunction
• C. Liver toxicity
• D. Renal dysfunction

Correct answer: A

Rationale: The correct answer is A: Pulmonary toxicity. Amiodarone is known for causing serious pulmonary toxicity, which can be fatal. Monitoring for pulmonary toxicity is crucial due to its potential severity. Choice B, thyroid dysfunction, is a common side effect of amiodarone but is not as immediately life-threatening as pulmonary toxicity. Choices C and D, liver toxicity and renal dysfunction, are potential side effects of amiodarone but are not as critical or as common as pulmonary toxicity, making them less important to monitor initially.

4. Which surgical procedure involves removing a portion of the lung?

• A. Lobectomy
• B. Pneumonectomy
• C. Tracheostomy
• D. Bronchoscopy

Correct answer: A

Rationale: A lobectomy is the surgical removal of a lobe of the lung. This procedure is commonly performed to treat conditions like lung cancer or severe lung diseases. Pneumonectomy involves removing an entire lung, making it incorrect. Tracheostomy is a surgical procedure to create an opening in the windpipe, not involving lung tissue removal. Bronchoscopy is a diagnostic procedure that allows visualization of the airways using a thin, flexible tube with a camera, not involving lung tissue removal.

5. Which of the following conditions is characterized by inflammation of the heart muscle, often due to a viral infection, leading to impaired heart function?

• A. Myocarditis
• B. Endocarditis
• C. Pericarditis
• D. Cardiomyopathy

Correct answer: A

Rationale: The correct answer is A, Myocarditis. Myocarditis is an inflammation of the heart muscle, typically caused by a viral infection. It can impair the heart's ability to pump blood efficiently, potentially leading to other complications. Endocarditis (choice B) is an inflammation of the inner lining of the heart chambers and valves. Pericarditis (choice C) is inflammation of the pericardium, the outer lining of the heart. Cardiomyopathy (choice D) is a disease of the heart muscle that affects the heart's ability to pump blood.
