Nursing Elites

1. The client is on furosemide (Lasix) and has a potassium level of 2.9 mEq/L. What is the nurse’s priority action?

• A. Administer potassium supplements.
• B. Hold the furosemide and notify the healthcare provider.
• C. Continue the current dose of furosemide.
• D. Decrease the dose of furosemide.

Correct answer: A

Rationale: The correct answer is A: Administer potassium supplements. A potassium level of 2.9 mEq/L indicates hypokalemia (low potassium levels). Furosemide (Lasix) is a loop diuretic that can cause potassium loss. Therefore, the priority action is to administer potassium supplements to correct the imbalance. Option B is incorrect because holding the furosemide without addressing the low potassium level could further worsen the imbalance. Option C is incorrect as continuing the current dose of furosemide without addressing the low potassium level could lead to complications. Option D is incorrect because decreasing the dose of furosemide does not directly address the low potassium level that needs immediate correction.

2. The client is on amiodarone. What is the most important side effect to monitor for?

• A. Pulmonary toxicity
• B. Thyroid dysfunction
• C. Liver toxicity
• D. Renal dysfunction

Correct answer: A

Rationale: The correct answer is A: Pulmonary toxicity. Amiodarone is known for causing serious pulmonary toxicity, which can be fatal. Monitoring for pulmonary toxicity is crucial due to its potential severity. Choice B, thyroid dysfunction, is a common side effect of amiodarone but is not as immediately life-threatening as pulmonary toxicity. Choices C and D, liver toxicity and renal dysfunction, are potential side effects of amiodarone but are not as critical or as common as pulmonary toxicity, making them less important to monitor initially.

3. Which medication relaxes the muscles around the airways, making it easier to breathe?

• A. Bronchodilator
• B. Corticosteroid
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Bronchodilator. Bronchodilators are medications that relax the muscles surrounding the airways, which helps to open them and makes breathing easier. Corticosteroids (choice B) work by reducing inflammation, antihistamines (choice C) are used to manage allergies, and mucolytics (choice D) help to break down and thin mucus in the airways.

4. What is the condition where the arteries in the brain become blocked or narrowed, leading to reduced blood flow and a potential stroke?

• A. Cerebral atherosclerosis
• B. Coronary artery disease
• C. Pulmonary embolism
• D. Peripheral artery disease

Correct answer: A

Rationale: Cerebral atherosclerosis is the correct answer. It is a condition where the arteries in the brain become blocked or narrowed due to plaque buildup, leading to reduced blood flow and an increased risk of stroke. Choice B, Coronary artery disease, specifically affects the arteries supplying blood to the heart, not the brain. Choice C, Pulmonary embolism, involves a blockage in the pulmonary artery that affects blood flow to the lungs, not the brain. Choice D, Peripheral artery disease, refers to a condition where blockages occur in arteries outside of the heart and brain, typically affecting the limbs.

5. 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 'Bronchitis.' Bronchitis refers to the inflammation of the bronchial tubes, which can be acute or chronic, leading to symptoms like coughing and increased mucus production. Choice B, 'Asthma,' is a chronic condition characterized by inflammation and narrowing of the airways, often causing wheezing and shortness of breath. Choice C, 'Pneumonia,' is an infection that inflames air sacs in one or both lungs, leading to symptoms like fever, cough, and difficulty breathing. Choice D, 'Cystic fibrosis,' is a genetic disorder that affects the lungs and digestive system, causing mucus buildup and respiratory issues.
