Nursing Elites

1. What is a condition where the heart's ability to pump blood is decreased, leading to fluid buildup in the lungs and other parts of the body?

• A. Heart failure
• B. Cardiomyopathy
• C. Pericarditis
• D. Myocarditis

Correct answer: A

Rationale: The correct answer is A, heart failure. Heart failure is a condition where the heart is unable to pump blood effectively, leading to fluid accumulation in the lungs and other areas. Choice B, Cardiomyopathy, refers to diseases of the heart muscle. Choices C and D, Pericarditis and Myocarditis, respectively, are conditions involving inflammation of the outer lining of the heart and the heart muscle itself, which may not always directly result in decreased pumping ability like heart failure does.

2. The nurse is administering digoxin to a client. What is the most important parameter to check before administration?

• A. Heart rate
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Heart rate. Before administering digoxin, it is crucial to check the client's heart rate because digoxin can cause bradycardia, making it essential to ensure the heart rate is within the appropriate range. Blood pressure, respiratory rate, and oxygen saturation are also important parameters to monitor in a clinical setting, but when administering digoxin, the focus should primarily be on the heart rate due to its potential effects on cardiac function.

3. Which heart chamber receives venous blood returning to the heart via the superior and inferior vena cava?

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Correct answer: A

Rationale: The correct answer is A: Right atrium. The right atrium is the heart chamber that receives deoxygenated blood returning from the body via the superior and inferior vena cava. The blood enters the right atrium from the vena cava and then passes through the tricuspid valve into the right ventricle. Choices B, C, and D are incorrect because the left atrium receives oxygenated blood from the lungs, the right ventricle pumps blood to the lungs for oxygenation, and the left ventricle pumps oxygenated blood to the body.

4. 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.

5. Which test measures how well the lungs work by assessing the amount of air the lungs can hold and how quickly air can be exhaled?

• A. Spirometry
• B. Pulse oximetry
• C. Arterial blood gas (ABG)
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Spirometry. Spirometry is a pulmonary function test that evaluates lung function by measuring the amount of air a person can exhale and how quickly, assisting in the diagnosis of conditions such as asthma and COPD. Choices B, C, and D are incorrect because Pulse oximetry measures oxygen saturation in the blood, Arterial blood gas (ABG) evaluates blood pH, oxygen, and carbon dioxide levels, and a Chest X-ray provides an image of the lungs but does not measure lung function.
