Questions of Respiratory System Questions
Question 1 of 5
In teaching a patient with hypertension about controlling the illness the nurse recognizes that?
Correct Answer: D
Rationale: Rationale: D is correct because lifestyle modifications, such as exercise and diet changes, are essential for managing hypertension. This approach can help lower blood pressure without the need for drug therapy. A is incorrect because not all patients with elevated BP require medication. B is incorrect as weight loss is beneficial but not the only factor in controlling BP. C is incorrect because limiting salt intake remains important even if taking a diuretic.
Question 2 of 5
If his R = 0.8 how much will his arterial pO2 fall?
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.
Question 3 of 5
The organ of the respiratory system that is kept open by rings of cartilage is the:
Correct Answer: D
Rationale: The correct answer is D: trachea. The trachea is kept open by rings of cartilage to prevent collapse during inhalation. The nose (A) is primarily involved in filtering, warming, and moistening air. The pharynx (B) is a common pathway for both air and food. The larynx (C) houses the vocal cords and aids in sound production but does not have cartilage rings to keep it open.
Question 4 of 5
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?
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.
Question 5 of 5
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:
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.
