Nursing Elites

1. The client is on hydrochlorothiazide and digoxin. What effect can the nurse expect?

• A. Hydrochlorothiazide increases digoxin levels.
• B. Hydrochlorothiazide decreases digoxin levels.
• C. Hydrochlorothiazide decreases potassium, increasing the risk of digoxin toxicity.
• D. Digoxin can increase the effectiveness of hydrochlorothiazide.

Correct answer: C

Rationale: The correct answer is C. Hydrochlorothiazide is a diuretic that can decrease potassium levels, which in turn can increase the risk of digoxin toxicity. Digoxin typically doesn't impact hydrochlorothiazide levels or effectiveness, making choices A, B, and D incorrect. Choice A stating that hydrochlorothiazide increases digoxin levels is inaccurate. Choice B suggesting that hydrochlorothiazide decreases digoxin levels is also incorrect. Choice D, stating that digoxin can increase the effectiveness of hydrochlorothiazide, is not a typical interaction seen between these medications.

2. What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?

• A. Chronic bronchitis
• B. Emphysema
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: Chronic bronchitis is the correct answer because it is a long-term condition characterized by inflammation and narrowing of the bronchial tubes in the lungs, commonly triggered by smoking. Emphysema involves damage to the air sacs in the lungs, not specifically the bronchial tubes. Asthma is a condition of reversible airway obstruction usually due to allergies or other triggers, not solely smoking. Tuberculosis is a bacterial infection that primarily affects the lungs but is not directly related to inflammation and narrowing of the bronchial tubes.

3. What is the buildup of plaque in the arteries that can lead to heart attack, stroke, and other cardiovascular diseases?

• A. Atherosclerosis
• B. Arteriosclerosis
• C. Hypertension
• D. Diabetes

Correct answer: A

Rationale: Atherosclerosis is the correct answer. It is the buildup of plaque in the arteries, leading to the narrowing of blood vessels, reduced blood flow, and an increased risk of heart attacks, strokes, and other cardiovascular diseases. Arteriosclerosis (choice B) refers to the hardening and thickening of arterial walls, while hypertension (choice C) is high blood pressure, and diabetes (choice D) is a metabolic disorder characterized by high blood sugar levels. Therefore, choices B, C, and D are incorrect in the context of the question.

4. What is a condition where the arteries supplying blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?

• A. Peripheral artery disease
• B. Atherosclerosis
• C. Varicose veins
• D. Raynaud's disease

Correct answer: A

Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is characterized by the narrowing or blockage of arteries that supply blood to the legs and feet, resulting in pain and difficulty walking. Choice B, Atherosclerosis, is a condition involving the buildup of plaque in the arteries but is not specific to the legs and feet. Varicose veins (Choice C) refer to enlarged, twisted veins usually occurring in the legs. Raynaud's disease (Choice D) involves episodes of reduced blood flow to the extremities, typically triggered by cold temperatures or stress, but it is not directly related to the arteries in the legs and feet.

5. Which valves close during ventricular systole and open during ventricular diastole?

• A. Semilunar valves
• B. Atrioventricular Valves
• C. Mitral valve
• D. Tricuspid valve

Correct answer: B

Rationale: The correct answer is B: Atrioventricular Valves. The atrioventricular (AV) valves, including the mitral valve and tricuspid valve, close during ventricular systole to prevent backflow of blood from the ventricles into the atria. They open during ventricular diastole to allow blood flow from the atria into the ventricles. Semilunar valves, choice A, are located at the exits of the ventricles and prevent backflow into the ventricles. The mitral valve and tricuspid valve, choices C and D, are specific types of AV valves.
