Chapter 19 : Introduction to the Respiratory System Questions
Question 1 of 5
The nurse is caring for a client whose respiratory status has declined since shift report. The client has tachypnea, is restless, and displays cyanosis. Which diagnostic test should the nurse perform first?
Correct Answer: C
Rationale: Pulse oximetry is a noninvasive method to determine arterial oxygen saturation. Normal values are 95% and above. Using this diagnostic test first provides rapid information of the client's respiratory system. All other options vary in amount of time and patient participation in determining further information regarding the respiratory system.
Question 2 of 5
The nurse is caring for a client with an exacerbation of COPD and scheduled for pulmonary function studies using a spirometer. Which client statement would the nurse clarify?
Correct Answer: D
Rationale: The nurse would clarify the client's statement of improper breathing technique. During a pulmonary function test using a spirometer, a nose clip prevents air from escaping through the client's nose when blowing into the spirometer. All other statements are correct.
Question 3 of 5
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?
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.
Question 4 of 5
A nurse is obtaining a health history from a client who reports hemoptysis for the past 2 months. The client reports occasional dyspnea. Which imaging study, ordered by the physician, will view the thoracic cavity while in motion?
Correct Answer: A
Rationale: Fluoroscopy enables the physician to view the thoracic cavity with all of its contents in motion. A fluoroscopy more precisely diagnoses the location of a tumor or lesion. An x-ray shows the size, shape, and position of the lungs. An MRI and CT produce axial views of the lungs.
Question 5 of 5
A nurse is instructing the client on the normal sensations that can occur when contrast medium is infused during pulmonary angiography. Which client statement demonstrates an understanding of the teaching?
Correct Answer: D
Rationale: During a pulmonary angiography, a contrast medium is injected into the femoral circulation. When the medium is infused, the client will feel warm and flushed, with a possibility of chest pain. The client will feel pressure when the catheter is inserted. The client does not typically feel light-headed or nauseated during this procedure.
