What is the name given to the respiratory ailment in which the bronchioles constrict severely?
- A. pleurisy
- B. emphysema
- C. bronchitis
- D. asthma
Correct Answer: D
Rationale: The correct answer is D: asthma. Asthma is a respiratory ailment characterized by severe constriction of the bronchioles due to inflammation and muscle contraction. This leads to difficulty breathing and wheezing. Pleurisy (A) is inflammation of the lining of the lungs, emphysema (B) is a long-term lung disease, and bronchitis (C) is inflammation of the bronchial tubes. Asthma specifically refers to the bronchioles constriction, making it the correct choice.

An emergency room nurse is assessing a male client who has sustained a blunt injury to the chest wall. Which of these signs would indicate the presence of a pneumothorax in this client?
- A. A low respiratory rate.
- B. Diminished breath sounds.
- C. The presence of a barrel chest.
- D. A sucking sound at the site of injury.
Correct Answer: B
Rationale: The correct answer is B: Diminished breath sounds. In the case of a pneumothorax, air leaks into the pleural space, causing the lung to collapse partially. This results in diminished or absent breath sounds on the affected side. A low respiratory rate (A) is a general sign of respiratory distress but not specific to pneumothorax. The presence of a barrel chest (C) is associated with conditions like chronic obstructive pulmonary disease (COPD) but not indicative of a pneumothorax. A sucking sound at the site of injury (D) is characteristic of an open pneumothorax, not necessarily present in all cases of pneumothorax.
Comiculate are the paired cartilage of pharynx in which shape
- A. club shape
- B. horn shape
- C. Bate shape
- D. butterfly shape
Correct Answer: B
Rationale: The correct answer is B: horn shape. The corniculate cartilages are small, horn-shaped structures located on the apex of the arytenoid cartilages in the larynx. These cartilages play a role in supporting the vocal folds. The other choices (A, C, D) are incorrect because the corniculate cartilages are not club-shaped, bate-shaped, or butterfly-shaped. It is crucial to understand the anatomical structure and function of the corniculate cartilages to identify the correct shape accurately.
A female client is undergoing a complete physical examination as a requirement for college. When checking the client's respiratory status, the nurse observes respiratory excursion to help assess:
- A. Lung vibrations
- B. Vocal sounds
- C. Breath sounds
- D. Chest movements.
Correct Answer: D
Rationale: The correct answer is D: Chest movements. When checking respiratory status, observing chest movements, known as respiratory excursion, helps assess the depth and symmetry of breathing. This provides valuable information about lung expansion and function. Lung vibrations (A) are assessed by tactile fremitus, vocal sounds (B) by auscultating for voice sounds, and breath sounds (C) by listening for air movement in the lungs. However, these do not directly assess respiratory excursion.
Which of the following nursing interventions are involved when caring for a client with influenza?
- A. Maintain airborne transmission precautions
- B. Complete bed rest
- C. Oxygen administration
- D. Immediate recognition of respiratory distress
Correct Answer: D
Rationale: The correct answer is D. Immediate recognition of respiratory distress is vital in clients with influenza, especially those at risk of complications. A (airborne precautions) is unnecessary unless the client is immunocompromised. B (complete bed rest) is outdated practice. C (oxygen administration) is only needed if hypoxia is present.
If his R = 0.8 how much will his arterial pO2 fall?
- A. 85mmHg
- B. 75mmHg
- C. 60mmHg
- D. 50mmHg
Correct Answer: D
Rationale: The correct answer is D (50mmHg). To calculate the fall in arterial pO2, we use the formula: Fall in pO2 = (Initial pO2) - (Initial pO2 x R). If R = 0.8, the fall in pO2 = (100mmHg) - (100mmHg x 0.8) = 100mmHg - 80mmHg = 20mmHg. Therefore, the arterial pO2 will fall by 20mmHg. Among the choices, D (50mmHg) is the closest to the calculated value of 20mmHg, making it the correct answer. Other choices (A, B, C) do not align with the calculated fall in pO2.
