Nursing Elites

1. 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.

2. What is a condition where a blood clot forms in a deep vein, usually in the legs, and can lead to serious complications if it travels to the lungs?

• A. Deep vein thrombosis (DVT)
• B. Pulmonary embolism
• C. Varicose veins
• D. Raynaud's disease

Correct answer: A

Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when a blood clot forms in a deep vein, usually in the legs. If the clot dislodges and travels to the lungs, it can lead to a serious condition called a pulmonary embolism. Choice B, pulmonary embolism, is incorrect as it is the consequence of a DVT clot traveling to the lungs, not the initial condition. Choices C and D, varicose veins, and Raynaud's disease, respectively, are unrelated conditions to the formation of blood clots in deep veins.

3. What procedure is used to visualize the airways and diagnose lung disease?

• A. Bronchoscopy
• B. Thoracentesis
• C. Pulmonary function test
• D. Chest X-ray

Correct answer: A

Rationale: Bronchoscopy is the correct answer because it is a procedure specifically designed to visualize the airways and diagnose lung diseases by allowing doctors to examine the inside of the airways. Thoracentesis involves the removal of fluid from the pleural space around the lungs, not the airways. Pulmonary function tests assess how well the lungs work but do not visualize the airways directly. A chest X-ray provides an image of the lungs and surrounding structures but does not involve direct visualization of the airways.

4. The client on digoxin has a potassium level of 3.0 mEq/L. What is the nurse’s priority action?

• A. Administer a potassium supplement
• B. Hold the digoxin and notify the healthcare provider
• C. Continue the current digoxin dose
• D. Administer Digibind

Correct answer: B

Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 3.0 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac arrhythmias. Administering a potassium supplement (choice A) without healthcare provider guidance can worsen the situation. Continuing the current digoxin dose (choice C) can further increase the risk of toxicity. Administering Digibind (choice D) is used in severe cases of digoxin toxicity, not for addressing low potassium levels.

5. What is a condition where the walls of the arteries become thickened and stiff, often due to the buildup of plaque, leading to reduced blood flow?

• A. Atherosclerosis
• B. Angina
• C. Hypertension
• D. Arrhythmia

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It is a condition characterized by the thickening and stiffening of artery walls due to plaque buildup, which restricts blood flow. Angina (choice B) is chest pain or discomfort caused by reduced blood flow to the heart. Hypertension (choice C) is high blood pressure, not directly related to arterial wall thickening. Arrhythmia (choice D) refers to irregular heart rhythms and is not specifically linked to artery wall changes like atherosclerosis.
