Nokea
A patient is having her tonsils removed. The patient asks the nurse what function the tonsils normally serve. Which of the following would be the most accurate response?
- A. The tonsils separate your windpipe from your throat when you swallow.
- B. The tonsils help to guard the body from invasion of organisms.
- C. The tonsils make enzymes that you swallow and which aid with digestion.
- D. The tonsils help with regulating the airflow down into your lungs.
Correct Answer: B
Rationale: The tonsils, the adenoids, and other lymphoid tissue encircle the throat. These structures are important links in the chain of lymph nodes guarding the body from invasion of organisms entering the nose and throat. The tonsils do not aid digestion, separate the trachea from the esophagus, or regulate airflow to the bronchi.

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

The nurse is performing a respiratory assessment of an adult patient and is attempting to distinguish between vesicular, bronchovesicular, and bronchial (tubular) breath sounds. The nurse should distinguish between these normal breath sounds on what basis?
- A. Their location over a specific area of the lung
- B. The volume of the sounds
- C. Whether they are heard on inspiration or expiration
- D. Whether or not they are continuous breath sounds
Correct Answer: A
Rationale: Normal breath sounds are distinguished by their location over a specific area of the lung; they are identified as vesicular, bronchovesicular, and bronchial (tubular) breath sounds. Normal breath sounds are heard on both inspiration and expiration, and are continuous. They are not distinguished solely on the basis of volume.
A patient on the medical unit has told the nurse that he is experiencing significant dyspnea, despite that he has not recently performed any physical activity. What assessment question should the nurse ask the patient while preparing to perform a physical assessment?
- A. On a scale from 1 to 10, how bad would you rate your shortness of breath?
- B. When was the last time you ate or drank anything?
- C. Are you feeling any nausea along with your shortness of breath?
- D. Do you think that some medication might help you catch your breath?
Correct Answer: A
Rationale: Gauging the severity of the patients dyspnea is an important part of the nursing process. Oral intake and nausea are much less important considerations. The nurse must perform assessment prior to interventions such as providing medication.
The nurse is caring for a patient who has returned to the unit following a bronchoscopy. The patient is asking for something to drink. Which criterion will determine when the nurse should allow the patient to drink fluids?
- A. Presence of a cough and gag reflex
- B. Absence of nausea
- C. Ability to demonstrate deep inspiration
- D. Oxygen saturation of 92%
Correct Answer: A
Rationale: After the procedure, it is important that the patient takes nothing by mouth until the cough reflex returns because the preoperative sedation and local anesthesia impair the protective laryngeal reflex and swallowing for several hours. Deep inspiration, adequate oxygen saturation levels, and absence of nausea do not indicate that oral intake is safe from the risk of aspiration.
A medical patient rings her call bell and expresses alarm to the nurse, stating, Ive just coughed up this blood. That cant be good, can it? How can the nurse best determine whether the source of the blood was the patients lungs?
- A. Obtain a sample and test the pH of the blood, if possible.
- B. Try to see if the blood is frothy or mixed with mucus.
- C. Perform oral suctioning to see if blood is obtained.
- D. Swab the back of the patients throat to see if blood is present.
Correct Answer: B
Rationale: Though not definitive, blood from the lung is usually bright red, frothy, and mixed with sputum. Testing the pH of nonarterial blood samples is not common practice and would not provide important data. Similarly, oral suctioning and swabbing the patients mouth would not reveal the source.
