The client has just had an invasive procedure to assess the respiratory system. What does the nurse know should be assessed on this client?
- A. Watery sputum
- B. Loss of consciousness
- C. Respiratory distress
- D. Masses in pleural space
Correct Answer: C
Rationale: After invasive procedures, the nurse must carefully check for signs of respiratory distress and blood-streaked sputum. Masses in the pleural space are a condition that affects fremitus. General examination of overall health and condition includes assessing the consciousness of a client.

The nurse is caring for clients on the neurological unit. Which triad of neurological mechanisms does the nurse identify as most responsible when there is abnormality in ventilation control?
- A. Medulla oblongata, cerebellum, and heart rate
- B. Pons, cerebellum, and oxygen receptors
- C. Medulla oblongata, mitral valve, and central receptors
- D. Aortic arch, pons, and CO2 receptor sites
Correct Answer: D
Rationale: Several mechanisms control ventilation. The respiratory center in the medulla oblongata and pons control rate and depth of respirations. The central chemoreceptors in the medulla and peripheral chemoreceptors in the aortic arch also provide a mechanism for detecting abnormalities and signal changes to alter the pH and levels of oxygen in the blood. The other options have an incorrect piece of the triad.
The nurse is suctioning a client who is unable to expectorate respiratory secretions. At which point does the nurse expect the client to experience coughing?
- A. When the catheter reaches the back of the pharynx
- B. When the catheter enters the main bronchus of the lung
- C. When the catheter reaches the point of the carina
- D. When the catheter tickles the uvula
Correct Answer: C
Rationale: Upon the catheter stimulating the carina, coughing and even bronchospasm may occur. Productive secretions may be loosened and eliminated via the suction catheter. When the catheter reaches the back of the pharynx near the uvula, the gag reflex is initiated. The suction catheter does not reach the entrance of the lung.
A client arrived in the emergency department with a sharp object penetrating the diaphragm. When planning nursing care, which client need would the nurse identify as a priority?
- A. Acute pain
- B. Infection risk
- C. Impaired gas exchange
- D. Ineffective airway clearance
Correct Answer: C
Rationale: The diaphragm separates the thoracic and abdominal cavities. On inspiration, the diaphragm contracts and moves downward, creating a partial vacuum. Without this vacuum, air is not as efficiently drawn into the thoracic cavity. Hypoxia or hypoxemia may occur from the poor availability of oxygen. Although the nursing diagnosis of acute pain is probable, gas exchange is a higher priority. Ineffective airway clearance is not the greatest concern because the problem is with ventilation. Infection risk is present but is not the highest-priority client need.
The nurse is caring for a client who states, 'I am really worried about the thoracentesis. I know I won't be able to sleep tonight.' Which statement is most helpful to the client at this time?
- A. Tell me what you are worried about.'
- B. Is there something that I can help you with?'
- C. Is there someone that you would like me to call to be with you?'
- D. The physician will see you before the procedure and can answer any questions.'
Correct Answer: A
Rationale: A thoracentesis is performed by inserting a needle into the wall under local anesthesia. The thoracentesis is often done at the bedside. Providing support to the client before, during, and after the treatment is a nursing responsibility. When the client expresses being worried, asking an open-ended question promotes communication and is most therapeutic. Asking if there is something that a nurse can do is a closed-ended question. Asking about calling someone to be with the client makes the nurse seem uninterested. Talking with the physician closes communication with the nurse, making the nurse seem uninterested.
A client presents to the emergency department in respiratory compromise. The client's temperature is 102.4?°F, heart rate 88 beats/minute and regular, and blood pressure 138/76 mm Hg. The client is dyspneic, pale, and expectorating green-tinged sputum. The physician orders medications including antibiotics, antipyretics, nebulizer treatments, and IV fluids. A chest x-ray and sputum culture are to be completed. Which physician order would the nurse complete before beginning antibiotic therapy?
- A. Chest x-ray
- B. Sputum culture
- C. Nebulizer treatments
- D. Initiating IV fluids
Correct Answer: B
Rationale: The nurse would obtain a sputum culture for sensitivity before beginning antibiotic therapy. Obtaining a sputum culture after beginning antibiotics can skew results. Once the sputum culture results are returned, the antibiotic can be closely aligned to kill the organism, if present. The other orders can be prioritized according to client needs.
