What is the condition where the lungs become filled with fluid, often due to heart failure, making it difficult to breathe?
- A. Pulmonary edema
- B. Pleural effusion
- C. Pulmonary hypertension
- D. Pneumothorax
Correct Answer: A
Rationale: Step-by-step rationale:
1. Pulmonary edema is the condition where lungs fill with fluid due to heart failure, causing breathing difficulty.
2. Pleural effusion is fluid accumulation in the pleural space, not in the lung tissue.
3. Pulmonary hypertension is high blood pressure in the pulmonary arteries, not related to fluid accumulation.
4. Pneumothorax is the presence of air in the pleural space, not fluid.
Summary:
Pulmonary edema is the correct answer as it specifically describes the condition of fluid accumulation in the lungs due to heart failure, leading to breathing difficulties. Pleural effusion, pulmonary hypertension, and pneumothorax are incorrect as they involve different pathologies not related to lung fluid accumulation.

What is the primary consideration when preparing to administer thrombolytic therapy to a patient who is experiencing an acute myocardial infarction (MI)?
- A. History of heart disease.
- B. Sensitivity to aspirin.
- C. Size and location of the MI.
- D. Time since onset of symptoms.
Correct Answer: D
Rationale: Thrombolytic therapy is most effective when administered within a few hours of symptom onset.
What is a type of pneumonia that is contracted by inhaling contaminated water droplets?
- A. Legionnaires' disease
- B. Tuberculosis
- C. Asbestosis
- D. Histoplasmosis
Correct Answer: A
Rationale: The correct answer is A: Legionnaires' disease. Legionnaires' disease is caused by inhaling water droplets contaminated with Legionella bacteria. These bacteria thrive in warm water, such as in air conditioning systems and hot tubs. The symptoms of Legionnaires' disease include high fever, cough, and shortness of breath.
B: Tuberculosis is caused by Mycobacterium tuberculosis and is transmitted through the air when an infected person coughs or sneezes.
C: Asbestosis is a lung disease caused by inhaling asbestos fibers, not contaminated water droplets.
D: Histoplasmosis is a fungal infection caused by inhaling spores found in soil with bird or bat droppings, not contaminated water droplets.
The client is on spironolactone (Aldactone). What is the most important dietary instruction?
- A. Avoid foods high in potassium.
- B. Increase intake of foods high in potassium.
- C. Avoid foods high in sodium.
- D. Increase intake of foods high in sodium.
Correct Answer: A
Rationale: The correct answer is A: Avoid foods high in potassium. Spironolactone is a potassium-sparing diuretic that can increase potassium levels in the body. Consuming foods high in potassium while on spironolactone can lead to hyperkalemia, which can be dangerous. By avoiding foods high in potassium, the client can help maintain a safe potassium level.
Summary:
- Choice B (Increase intake of foods high in potassium) is incorrect because it can lead to hyperkalemia when combined with spironolactone.
- Choice C (Avoid foods high in sodium) is unrelated to spironolactone's mechanism of action.
- Choice D (Increase intake of foods high in sodium) is incorrect as it is not relevant to the dietary instruction needed for a client on spironolactone.
What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?
- A. Corticosteroid
- B. Bronchodilator
- C. Antihistamine
- D. Mucolytic
Correct Answer: A
Rationale: The correct answer is A: Corticosteroid. Corticosteroids work by reducing inflammation in the airways, which is a key factor in asthma attacks. They help prevent asthma symptoms by decreasing swelling and mucus production in the airways. Bronchodilators (B) help to relax and widen the airways but do not target inflammation. Antihistamines (C) are used to treat allergies and do not directly address asthma inflammation. Mucolytics (D) help to thin mucus in the airways but do not specifically target airway inflammation in asthma.
What is the condition where the body's immune system attacks its tissues, causing inflammation and damage?
- A. Autoimmune disease
- B. Infectious disease
- C. Allergic reaction
- D. Degenerative disease
Correct Answer: A
Rationale: The correct answer is A: Autoimmune disease. In autoimmune diseases, the immune system mistakenly attacks the body's tissues, leading to inflammation and damage. This occurs due to a breakdown in immune tolerance, resulting in the immune system targeting self-antigens. This leads to chronic inflammation and tissue damage. In contrast, infectious diseases are caused by pathogens, allergic reactions are responses to harmless substances, and degenerative diseases involve the gradual deterioration of tissues over time. Therefore, autoimmune disease best fits the description provided in the question.
