Chapter 20 : Assessment of Respiratory Function Questions
Question 1 of 5
A patient asks the nurse why an infection in his upper respiratory system is affecting the clarity of his speech. Which structure serves as the patients resonating chamber in speech?
Correct Answer: C
Rationale: A prominent function of the sinuses is to serve as a resonating chamber in speech. The trachea, also known as the windpipe, serves as the passage between the larynx and the bronchi. The pharynx is a tubelike structure that connects the nasal and oral cavities to the larynx. The pharynx also functions as a passage for the respiratory and digestive tracts. The major function of the larynx is vocalization through the function of the vocal cords. The vocal cords are ligaments controlled by muscular movements that produce sound.
Question 2 of 5
A patient with a decreased level of consciousness is in a recumbent position. How should the nurse best assess the lung fields for a patient in this position?
Correct Answer: B
Rationale: Assessment of the anterior and posterior lung fields is part of the nurses routine evaluation. If the patient is recumbent, it is essential to turn the patient to assess all lung fields so that dependent areas can be assessed for breath sounds, including the presence of normal breath sounds and adventitious sounds. Failure to examine the dependent areas of the lungs can result in missing significant findings. This makes the other given options unacceptable.
Question 3 of 5
A patient is undergoing testing to see if he has a pleural effusion. Which of the nurses respiratory assessment findings would be most consistent with this diagnosis?
Correct Answer: C
Rationale: Assessment findings consistent with a pleural effusion include affected lung fields being dull to percussion and absence of breath sounds. A pleural friction rub may also be present. The other listed signs are not typically associated with a pleural effusion.
Question 4 of 5
The nurse doing rounds at the beginning of a shift notices a sputum specimen in a container sitting on the bedside table in a patients room. The patient says the specimen is about 4 hours old. What action should the nurse take?
Correct Answer: B
Rationale: Sputum samples should be submitted to the laboratory as soon as possible. Allowing the specimen to stand for several hours in a warm room results in the overgrowth of contaminated organisms and may make it difficult to identify the pathogenic organisms. Refrigeration of the sputum specimen and the addition of normal saline are not appropriate actions.
Question 5 of 5
The nurse is assessing a newly admitted medical patient and notes there is a depression in the lower portion of the patients sternum. This patients health record should note the presence of what chest deformity?
Correct Answer: B
Rationale: A funnel chest occurs when there is a depression in the lower portion of the sternum, and this may lead to compression of the heart and great vessels, resulting in murmurs. A barrel chest is characterized by an increase in the anteroposterior diameter of the thorax and is a result of overinflation of the lungs. A pigeon chest occurs as a result of displacement of the sternum and includes an increase in the anteroposterior diameter. Kyphoscoliosis, which is characterized by elevation of the scapula and a corresponding S-shaped spine, limits lung expansion within the thorax.
