Which of the following is a sign or symptom characteristic of the later stages of TB?
- A. Fatigue
- B. Hemoptysis
- C. Anorexia
- D. Weight loss
Correct Answer: B
Rationale: The correct answer is B. Hemoptysis (coughing up blood) is a hallmark sign of advanced TB. A (fatigue), C (anorexia), and D (weight loss) are earlier or nonspecific symptoms.

Carbonic anhydrase
- A. combines with water to form carbonic acid
- B. dissociates into bicarbonate and hydrogen ions.
- C. is normally found in red blood cells.
- D. all of the above
Correct Answer: D
Rationale: Carbonic anhydrase catalyzes the reversible reaction between carbon dioxide and water to form carbonic acid, which then dissociates into bicarbonate and hydrogen ions. It is indeed found in red blood cells, aiding in CO2 transport. Therefore, all the statements are true, making option D the correct answer.
The volume of air that can be exhaled after normal exhalation is the
- A. tidal volume
- B. residual volume
- C. inspiratory reserve volume
- D. expiratory reserve volume
Correct Answer: D
Rationale: The correct answer is D: expiratory reserve volume. After normal exhalation (tidal volume), the expiratory reserve volume represents the additional volume of air that can be forcefully exhaled. This volume is used during activities requiring increased breathing effort. Choices A and C are incorrect because tidal volume is the volume of air inhaled or exhaled during normal breathing, and inspiratory reserve volume is the extra volume of air that can be inhaled after a normal inhalation. Choice B, residual volume, is the volume of air remaining in the lungs after maximal exhalation and cannot be exhaled voluntarily.
A male client with chronic obstructive pulmonary disease (COPD) is recovering from a myocardial infarction. Because the client is extremely weak and can't produce an effective cough, the nurse should monitor closely for:
- A. Pleural effusion
- B. Pulmonary edema
- C. Atelectasis
- D. Oxygen toxicity
Correct Answer: C
Rationale: The correct answer is C: Atelectasis. In a client with COPD recovering from a myocardial infarction, the weakened state and ineffective cough can lead to the collapse of alveoli, causing atelectasis. This condition can further impair gas exchange and oxygenation, leading to respiratory distress. Monitoring for atelectasis is crucial to prevent complications. Pleural effusion (A) and pulmonary edema (B) are not directly related to the client's condition and symptoms. Oxygen toxicity (D) is a potential concern with high oxygen therapy but is not the most immediate risk for this client scenario.
during rest state normal breathing called
- A. Breathing
- B. diaphragmatic
- C. Diaphragmatic breathing
- D. non
Correct Answer: C
Rationale: The correct answer is C: Diaphragmatic breathing. During rest, normal breathing involves the diaphragm contracting and moving downward to draw air into the lungs. This type of breathing is known as diaphragmatic breathing. Choice A (Breathing) is too broad and does not specify the involvement of the diaphragm. Choice B (Diaphragmatic) does not fully describe the process of breathing during rest. Choice D (Non) is incorrect as it does not provide any information related to the breathing process during rest state. Therefore, C is the most accurate choice as it specifically identifies the type of breathing that occurs during rest.
During a health promotion program, why should the nurse plan to target women in a discussion of lung cancer prevention?
- A. Women develop lung cancer at a younger age than men.
- B. More women die of lung cancer than die from breast cancer.
- C. Women have a worse prognosis from lung cancer than do men.
- D. Women are more likely to develop small cell carcinoma than men.
Correct Answer: D
Rationale: Since the statement "Women are more likely to develop small cell carcinoma than men" is not a valid reason for targeting women in a discussion of lung cancer prevention, it becomes the correct answer in this context.
