Nursing Elites

1. What is a condition characterized by an abnormal buildup of fluid between the layers of tissue lining the lungs and chest cavity?

• A. Pleural effusion
• B. Pulmonary edema
• C. Atelectasis
• D. Sarcoidosis

Correct answer: A

Rationale: Pleural effusion is the correct answer as it refers to the accumulation of excess fluid between the layers of the pleura surrounding the lungs and chest cavity. This condition can be caused by various factors such as infections, heart failure, or cancer. Pulmonary edema (choice B) involves fluid accumulation in the lungs' air sacs and is not specific to the pleura. Atelectasis (choice C) is the collapse or closure of a lung leading to airless lung tissue and is not related to fluid buildup. Sarcoidosis (choice D) is a condition characterized by the growth of tiny collections of inflammatory cells in different parts of the body, not specifically involving fluid accumulation in the pleural space.

2. What is the average cardiac output?

• A. Approximately 4 to 6 L per minute
• B. Approximately 4 to 8 L per minute
• C. Approximately 5 to 8 L per minute
• D. Approximately 3 to 7 L per minute

Correct answer: B

Rationale: The correct answer is B: Approximately 4 to 8 L per minute. Cardiac output is defined as the volume of blood the heart pumps per minute, typically ranging between 4 to 8 liters. Choices A, C, and D provide ranges that are either too narrow or outside the standard average values for cardiac output, making them incorrect.

3. Identify the three layers of the heart:

• A. Endocardium, Myocardium, Epicardium
• B. Epicardium, Pericardium, Endocardium
• C. Myocardium, Endocardium, Pericardium
• D. Pericardium, Myocardium, Endocardium

Correct answer: A

Rationale: The correct answer is A: Endocardium, Myocardium, Epicardium. The heart consists of three main layers: the endocardium, which lines the inner chambers of the heart; the myocardium, the middle layer responsible for the heart's pumping action; and the epicardium, the outermost layer that protects the heart. Choices B, C, and D are incorrect as they do not list the heart's layers in the correct order or combination.

4. What test measures the oxygen level in the blood, often used to monitor patients with respiratory or cardiovascular conditions?

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

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, commonly used to monitor respiratory and cardiovascular health. Arterial blood gas (ABG) measures the levels of oxygen and carbon dioxide in the blood, providing more detailed information than pulse oximetry. Echocardiogram is an ultrasound test used to visualize the heart's structure and function, while a chest X-ray is used to visualize the structures in the chest, such as the heart, lungs, and bones.

5. The client is on digoxin and has severe digoxin toxicity. What is the nursing priority action?

• A. Check the potassium level.
• B. Give Digibind as an antidote.
• C. Change the dosing of digoxin to every other day.
• D. Administer a potassium supplement to decrease digoxin toxicity.

Correct answer: B

Rationale: The correct answer is to give Digibind as an antidote in cases of severe digoxin toxicity. Digibind works by binding to digoxin and preventing it from causing further harm. Checking the potassium level (choice A) is important but not the priority when the client has severe toxicity. Changing the dosing to every other day (choice C) is not appropriate in the setting of severe toxicity where immediate action is required. Giving a potassium supplement (choice D) may be needed eventually, but the priority is to administer Digibind to counteract the toxic effects of digoxin.
