In cases of myocardial infarction leading to shock, which medication is appropriate to counteract shock?
- A. Atropine
- B. Dopamine
- C. Digoxin
- D. Adenosine
Correct Answer: B
Rationale: The correct answer is B: Dopamine. In myocardial infarction leading to shock, dopamine is appropriate due to its positive inotropic effects, increasing cardiac output and blood pressure. Atropine is not indicated for shock in this context. Digoxin may be contraindicated in acute myocardial infarction. Adenosine is not used in managing shock.

What is the term for inflammation of the bronchial tubes, often leading to a persistent cough and mucus production?
- A. Bronchitis
- B. Asthma
- C. Pneumonia
- D. Cystic fibrosis
Correct Answer: A
Rationale: The correct answer is A: Bronchitis. Bronchitis refers to inflammation of the bronchial tubes, causing symptoms such as persistent cough and mucus production. This condition is often caused by viral or bacterial infections, irritants, or smoking. Asthma (B) is a chronic respiratory condition characterized by airway inflammation and tightening, leading to difficulty breathing. Pneumonia (C) is an infection in the lungs, typically caused by bacteria, viruses, or fungi. Cystic fibrosis (D) is a genetic disorder affecting the lungs and other organs, leading to thick mucus production and recurrent infections. Therefore, the term that specifically describes inflammation of the bronchial tubes is bronchitis, making it the correct answer in this scenario.

The client is receiving digoxin and has a potassium level of 2.8 mEq/L. What is the nurse's priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Increase the dose of digoxin.
- C. Continue the current dose of digoxin.
- D. Administer potassium supplements.
Correct Answer: A
Rationale: The correct answer is A: Hold the digoxin and notify the healthcare provider. Digoxin toxicity is more likely to occur in patients with low potassium levels. With a potassium level of 2.8 mEq/L, the client is at risk for digoxin toxicity. Holding the digoxin and notifying the healthcare provider is the priority action to prevent potential harm to the client.
B: Increasing the dose of digoxin would exacerbate the risk of digoxin toxicity in a client with low potassium levels.
C: Continuing the current dose of digoxin without addressing the low potassium level could lead to digoxin toxicity.
D: Administering potassium supplements alone may not be sufficient to address the potential digoxin toxicity. Holding the digoxin is the priority action.
