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. What procedure involves using a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent?

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

Correct answer: A

Rationale: The correct answer is A, Angioplasty. Angioplasty is a procedure that uses a balloon to open a narrowed or blocked blood vessel, often followed by the placement of a stent to maintain vessel patency. Choice B, Valve replacement, involves replacing damaged heart valves, not treating narrowed blood vessels. Choice C, Coronary artery bypass graft (CABG), is a procedure to bypass blocked coronary arteries, not directly open them using a balloon. Choice D, Endarterectomy, is a surgical procedure to remove plaque from the inner lining of an artery, not involving the use of a balloon and stent to open a vessel.

3. What is a condition where the blood supply to the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?

• A. Stroke
• B. Transient ischemic attack (TIA)
• C. Myocardial infarction
• D. Angina

Correct answer: A

Rationale: A stroke is the correct answer. A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to a lack of oxygen and nutrients to the brain tissue, causing brain damage. Choices B, C, and D are incorrect because a transient ischemic attack (TIA) is a temporary blockage of blood flow to the brain with no lasting damage, myocardial infarction is a heart attack due to blockage of blood flow to the heart muscle, and angina is chest pain caused by reduced blood flow to the heart.

4. What is a condition where the heart beats too slowly, reducing the amount of blood pumped to the body?

• A. Bradycardia
• B. Tachycardia
• C. Atrial fibrillation
• D. Ventricular fibrillation

Correct answer: A

Rationale: Bradycardia is the correct answer. It is a condition characterized by a slow heart rate, which reduces the amount of blood pumped to the body. This can lead to symptoms like fatigue and dizziness. Choice B, Tachycardia, is the opposite condition where the heart beats too fast. Choices C and D, Atrial fibrillation and Ventricular fibrillation, refer to irregular and potentially life-threatening rapid heart rhythms involving the atria and ventricles respectively, not a slow heart rate.

5. What test uses high-frequency sound waves to create images of the heart, allowing doctors to assess its structure and function?

• A. Echocardiogram
• B. MRI
• C. CT scan
• D. X-ray

Correct answer: A

Rationale: The correct answer is an echocardiogram. An echocardiogram utilizes high-frequency sound waves (ultrasound) to create images of the heart, enabling doctors to evaluate its structure, function, and detect any abnormalities. MRI (Choice B) uses magnetic fields and radio waves to produce detailed images of the body's structures. CT scan (Choice C) combines X-rays and computer technology to create cross-sectional images of the body. X-ray (Choice D) uses electromagnetic radiation to produce images of the internal structures of the body, but it is not the most suitable for assessing the heart's structure and function.
