1. What procedure involves inserting a needle into the pleural space to remove excess fluid and help the patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Spirometry
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to remove excess fluid, aiding in easier breathing. Bronchoscopy (Choice B) is a procedure to visualize the airways and diagnose lung problems, not specifically for fluid drainage. Spirometry (Choice C) is a test to measure lung function, not a procedure for fluid removal. Arterial blood gas (ABG) (Choice D) is a blood test to assess oxygen and carbon dioxide levels in the blood, not a procedure for draining fluid from the pleural space.

2. When administering enoxaparin (Lovenox) to a client for DVT prophylaxis, what is the most important lab value to monitor?

• A. Platelet count
• B. PT/INR
• C. aPTT
• D. Hemoglobin

Correct answer: A

Rationale: The correct answer is A: Platelet count. When administering enoxaparin (Lovenox) for DVT prophylaxis, it is crucial to monitor the platelet count as enoxaparin can lead to thrombocytopenia, a decrease in platelet levels. Monitoring the platelet count helps in early detection of this potential adverse effect. Choices B, C, and D are incorrect because PT/INR, aPTT, and hemoglobin levels are not the most important lab values to monitor specifically for enoxaparin administration and DVT prophylaxis.

3. What is the term used to describe a condition where the blood flow to the brain is temporarily interrupted, often referred to as a 'mini-stroke'?

• A. Transient ischemic attack (TIA)
• B. Stroke
• C. Myocardial infarction
• D. Pulmonary embolism

Correct answer: A

Rationale: The correct answer is A: Transient ischemic attack (TIA). A transient ischemic attack (TIA) is often called a 'mini-stroke' because it is characterized by a temporary interruption of blood flow to the brain, resulting in stroke-like symptoms that typically resolve within a short period. Choice B, 'Stroke,' is incorrect because a stroke involves a more prolonged interruption of blood flow, leading to lasting brain damage. Choices C and D, 'Myocardial infarction' and 'Pulmonary embolism,' are unrelated conditions involving the heart and lungs, respectively, and do not describe a temporary interruption of blood flow to the brain.

4. What structures hold up the AV valves and are anchored to the ventricular wall by the papillary muscles?

• A. Chordae tendineae
• B. Papillary muscles
• C. Semilunar valves
• D. Aortic valve

Correct answer: A

Rationale: The correct answer is A: Chordae tendineae. Chordae tendineae are fibrous cords that connect the AV valves to the papillary muscles, preventing the valves from inverting during ventricular contraction. Papillary muscles (choice B) anchor the chordae tendineae to the ventricular wall but do not hold up the AV valves directly. Semilunar valves (choice C) are located between the ventricles and the major arteries and are not involved in holding up the AV valves. The aortic valve (choice D) is one of the semilunar valves and is not responsible for holding up the AV valves.

5. What is a chronic condition where the airways in the lungs become damaged and widened, leading to mucus buildup and frequent infections?

• A. Bronchiectasis
• B. Chronic bronchitis
• C. Pneumoconiosis
• D. Asthma

Correct answer: A

Rationale: Bronchiectasis is a chronic condition characterized by the damage and widening of the airways in the lungs, resulting in mucus accumulation and recurrent lung infections. Choice B, chronic bronchitis, involves inflammation of the bronchial tubes and excessive mucus production but does not specifically mention airway damage and widening. Choice C, pneumoconiosis, refers to lung diseases caused by inhalation of mineral dust particles, not airway damage and mucus buildup. Choice D, asthma, is a chronic condition characterized by airway inflammation and narrowing, leading to breathing difficulties, but it does not involve the widening and damage of the airways as seen in bronchiectasis.
