Nursing Elites

1. The client is receiving intravenous dopamine. What is the most important nursing assessment?

• A. Monitor heart rate and rhythm
• B. Monitor blood pressure
• C. Monitor respiratory rate
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The correct answer is to monitor heart rate and rhythm when a client is receiving intravenous dopamine. Dopamine is known to potentially cause arrhythmias, making this assessment crucial. While monitoring blood pressure, respiratory rate, and oxygen saturation are important nursing assessments, they are not the most critical when dopamine is being administered.

2. This is a test that measures the oxygen saturation level in the blood, often used to assess respiratory function.

• A. Pulse oximetry
• B. Spirometry
• C. Arterial blood gas (ABG)
• D. Lung function test

Correct answer: A

Rationale: The correct answer is A, Pulse oximetry. Pulse oximetry is a non-invasive test that measures the oxygen saturation level in the blood, helping to assess respiratory and cardiovascular function. Choice B, Spirometry, measures lung function by assessing airflow and volume. Choice C, Arterial blood gas (ABG), evaluates the acidity, oxygen, and carbon dioxide levels in the blood. Choice D, Lung function test, is a broad term that may include various tests to assess lung health, but specifically measuring oxygen saturation is done through pulse oximetry.

3. Which of the following is a type of heart valve disease where the aortic valve becomes narrowed, restricting blood flow from the heart to the rest of the body?

• A. Aortic stenosis
• B. Mitral stenosis
• C. Tricuspid regurgitation
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is Aortic stenosis. In aortic stenosis, the aortic valve becomes narrowed, which obstructs the blood flow from the heart to the rest of the body. This condition can lead to symptoms like chest pain, shortness of breath, and fainting. Mitral stenosis (choice B) involves narrowing of the mitral valve, not the aortic valve. Tricuspid regurgitation (choice C) is a condition where the tricuspid valve leaks, causing blood to flow backward in the heart. Pulmonary hypertension (choice D) is high blood pressure in the arteries of the lungs.

4. What procedure involves inserting a flexible tube with a light and camera into the airways to examine the lungs and collect samples?

• A. Bronchoscopy
• B. Thoracentesis
• C. Lung biopsy
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A: Bronchoscopy. Bronchoscopy is a procedure that entails inserting a flexible tube with a light and camera into the airways to examine the lungs and collect tissue or fluid samples. This procedure is commonly performed to diagnose lung conditions such as infections, tumors, or obstructions. Choice B, thoracentesis, involves inserting a needle into the pleural space to remove fluid for diagnostic or therapeutic purposes related to the lungs or pleura, not the airways. Choice C, lung biopsy, typically involves obtaining tissue samples from the lungs for further examination, not directly visualizing the airways. Choice D, chest X-ray, is a diagnostic imaging technique that uses radiation to create images of the chest area, providing a different type of information compared to bronchoscopy.

5. What is the amount of tension the ventricle must develop during contraction to eject blood from the left ventricle into the aorta?

• A. Afterload
• B. Preload
• C. Automaticity
• D. Ejection fraction

Correct answer: A

Rationale: Afterload is the correct answer because it refers to the pressure or tension that the ventricle must overcome during systole to eject blood into the aorta. Preload, on the other hand, is the degree of stretch of the ventricular muscle at the end of diastole before it contracts. Automaticity is the ability of the heart to generate electrical impulses independently, and ejection fraction is the percentage of blood pumped out of the ventricle with each heartbeat. Therefore, in the context of the question, afterload best describes the amount of tension the ventricle must develop to eject blood into the aorta.
