1. 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.

2. What is a life-threatening condition where the heart suddenly stops beating?

• A. Cardiac arrest
• B. Myocardial infarction
• C. Heart failure
• D. Atrial fibrillation

Correct answer: A

Rationale: Cardiac arrest is the correct answer. It is a sudden, unexpected loss of heart function, breathing, and consciousness, typically resulting in death if not treated immediately. Myocardial infarction (choice B) refers to a heart attack caused by a blockage in the coronary arteries. Heart failure (choice C) is a chronic condition where the heart is unable to pump blood efficiently. Atrial fibrillation (choice D) is an irregular and often rapid heart rate that can lead to complications but is not the same as cardiac arrest.

3. What type of stroke is caused by a blockage in an artery supplying blood to the brain?

• A. Ischemic stroke
• B. Hemorrhagic stroke
• C. Transient ischemic attack
• D. Embolism

Correct answer: A

Rationale: The correct answer is A: Ischemic stroke. Ischemic stroke occurs when a blood clot blocks an artery supplying blood to the brain, leading to brain damage. Choice B, Hemorrhagic stroke, is caused by bleeding in the brain, not a blockage. Choice C, Transient ischemic attack, is a temporary blockage of blood flow to the brain with symptoms similar to a stroke but typically lasting only a few minutes. Choice D, Embolism, refers to a blood clot or other particle that travels through the bloodstream and blocks a blood vessel.

4. What is a genetic disorder that affects the lungs and digestive system, leading to thick, sticky mucus that can clog the airways?

• A. Cystic fibrosis
• B. COPD
• C. Bronchiectasis
• D. Pulmonary fibrosis

Correct answer: A

Rationale: The correct answer is A, cystic fibrosis. Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system. It leads to the production of thick, sticky mucus that can clog the airways, causing respiratory issues. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is a different condition usually caused by smoking or exposure to irritants. Choice C, bronchiectasis, involves the widening and scarring of the airways, not the production of thick mucus. Choice D, pulmonary fibrosis, is a lung disease characterized by scarring of the lung tissue, not excessive mucus production.

5. What is a condition where the lungs become stiff and scarred, making it difficult to breathe and get enough oxygen into the bloodstream?

• A. Pulmonary fibrosis
• B. Pulmonary edema
• C. Pulmonary embolism
• D. Pulmonary hypertension

Correct answer: A

Rationale: Pulmonary fibrosis is a condition characterized by the stiffening and scarring of the lungs, leading to difficulty breathing and impairing the transfer of oxygen into the bloodstream. Pulmonary edema refers to fluid accumulation in the lungs, causing breathing difficulties due to fluid filling the air sacs. Pulmonary embolism is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot. Pulmonary hypertension is high blood pressure in the arteries of the lungs, which can lead to strain on the heart and affect oxygen levels in the blood.
