Nokea
The nurse is caring for a patient who has a pleural effusion and who underwent a thoracoscopic procedure earlier in the morning. The nurse should prioritize assessment for which of the following?
- A. Sputum production
- B. Shortness of breath
- C. Throat discomfort
- D. Epistaxis
Correct Answer: B
Rationale: Follow-up care in the health care facility and at home involves monitoring the patient for shortness of breath (which might indicate a pneumothorax). All of the listed options are relevant assessment findings, but shortness of breath is the most serious complication.

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?
- A. Trachea
- B. Pharynx
- C. Paranasal sinuses
- D. Larynx
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.
A sputum study has been ordered for a patient who has developed coarse chest crackles and a fever. At what time should the nurse best collect the sample?
- A. Immediately after a meal
- B. First thing in the morning
- C. At bedtime
- D. After a period of exercise
Correct Answer: B
Rationale: Sputum samples ideally are obtained early in the morning before the patient has had anything to eat or drink.
The ED nurse is assessing a patient complaining of dyspnea. The nurse auscultates the patients chest and hears wheezing throughout the lung fields. What might this indicate?
- A. The patient has a narrowed airway.
- B. The patient has pneumonia.
- C. The patient needs physiotherapy.
- D. The patient has a hemothorax.
Correct Answer: A
Rationale: Wheezing is a high-pitched, musical sound that is often the major finding in a patient with bronchoconstriction or airway narrowing. Wheezing is not normally indicative of pneumonia or hemothorax. Wheezing does not indicate the need for physiotherapy.
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?
- A. Immediately take the sputum specimen to the laboratory.
- B. Discard the specimen and assist the patient in obtaining another specimen.
- C. Refrigerate the sputum specimen and submit it once it is chilled.
- D. Add a small amount of normal saline to moisten the specimen.
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.
A gerontologic nurse is analyzing the data from a patients focused respiratory assessment. The nurse is aware that the amount of respiratory dead space increases with age. What is the effect of this physiological change?
- A. Increased diffusion of gases
- B. Decreased diffusion capacity for oxygen
- C. Decreased shunting of blood
- D. Increased ventilation
Correct Answer: B
Rationale: The amount of respiratory dead space increases with age. Combined with other changes, this results in a decreased diffusion capacity for oxygen with increasing age, producing lower oxygen levels in the arterial circulation. Decreased shunting and increased ventilation do not occur with age.
