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 term for the ability of cardiac cells to respond to a stimulus by initiating a cardiac impulse?

• A. Excitability
• B. Contractility
• C. Rhythmicity
• D. Conductivity

Correct answer: A

Rationale: The correct answer is A, Excitability. Excitability is the ability of cardiac cells to respond to a stimulus by initiating a cardiac impulse. Choice B, Contractility, refers to the ability of cardiac muscle to shorten forcibly. Choice C, Rhythmicity, refers to the cardiac muscle's ability to contract rhythmically. Choice D, Conductivity, refers to the ability of the heart's cells to conduct electrical impulses.

3. This is a type of therapy that involves removing fluid from the lungs, typically through the use of diuretics.

• A. Diuretic therapy
• B. Oxygen therapy
• C. Inhaler therapy
• D. Antihistamine therapy

Correct answer: A

Rationale: The correct answer is A: Diuretic therapy. Diuretic therapy involves the use of medications that help remove excess fluid from the body, often used to treat conditions like pulmonary edema. Choice B, Oxygen therapy, is used to provide oxygen to patients with breathing difficulties but does not involve removing fluid from the lungs. Choice C, Inhaler therapy, is used to deliver medication directly to the lungs to help with respiratory conditions but does not focus on removing fluid. Choice D, Antihistamine therapy, is used to treat allergies by blocking histamine but is not related to removing fluid from the lungs.

4. The nurse is caring for a client on digoxin with a heart rate of 48 bpm. What is the nurse’s priority action?

• A. Hold the digoxin and notify the healthcare provider.
• B. Administer the digoxin as ordered.
• C. Administer atropine to increase the heart rate.
• D. Increase the dose of digoxin.

Correct answer: A

Rationale: In this scenario, the nurse's priority action should be to hold the digoxin and notify the healthcare provider. A heart rate of 48 bpm is low, and digoxin, being a medication that can further decrease the heart rate, should be withheld. Administering the digoxin as ordered (Choice B) would not be appropriate in this situation as it can exacerbate bradycardia. Atropine (Choice C) is not the initial treatment for this scenario; holding the digoxin is the first action. Increasing the dose of digoxin (Choice D) would be contraindicated due to the client's bradycardia. Therefore, the correct action is to hold the digoxin and inform the healthcare provider for further guidance.

5. The healthcare provider is monitoring a client on an ACE inhibitor. What lab value is most important to monitor?

• A. Potassium
• B. Sodium
• C. Creatinine
• D. Calcium

Correct answer: A

Rationale: The correct answer is A: Potassium. When a client is on an ACE inhibitor, it is crucial to monitor potassium levels because ACE inhibitors can lead to an increase in potassium, potentially causing hyperkalemia. Monitoring sodium levels (Choice B) is not as critical in this scenario. Creatinine levels (Choice C) are important for assessing kidney function but are not the most crucial lab value to monitor with ACE inhibitors. Calcium levels (Choice D) are not directly affected by ACE inhibitors and are not the priority for monitoring in this case.
