The nurse is caring for a 30-year-old American Indian female who is taking Rifater, a drug containing rifampin, isoniazid, and pyrazinamide. The patient asks how long she will have to take the medication. Which response explains when the patient may discontinue the medication?

A. Have the client lean over an over-the-bed table:This position is sometimes used during posterior thoracic examination or for percussing lung fields, but it is not standard for routine chest auscultation. Most chest sounds can be assessed with the client sitting upright or lying down.

B. Use the bell of the stethoscope held lightly against the chest:The bell is best for detecting low-pitched sounds like some heart murmurs, not respiratory sounds. Lung sounds are higher-pitched and require use of the diaphragm for accurate auscultation.

C. Use the diaphragm of the stethoscope held firmly against the chest:This is the correct technique for auscultating lung sounds, which are typically high-pitched. Holding the diaphragm firmly ensures clear transmission of breath sounds such as crackles, wheezes, or rhonchi.

D. Instruct the client to take deep, rapid breaths through their nose:Deep breathing is appropriate during auscultation, but it should be done through the mouth. Breathing through the nose may reduce air entry and obscure abnormal sounds, making it harder to detect lung pathology.

A. Obtain a throat culture:Attempting to visualize or culture the throat in a child with epiglottitis is dangerous and can trigger laryngospasm, leading to sudden airway obstruction. Any procedure that manipulates the airway should be avoided.

B. Administer humidified oxygen:Humidified oxygen helps ease breathing and reduce airway irritation. It is a supportive measure that can be safely administered without disturbing the airway and is commonly used in cases of respiratory distress such as epiglottitis.

C. Administer acetaminophen for fever:Fever is a common symptom of epiglottitis, and acetaminophen can be safely used to reduce temperature and increase comfort. It poses no risk to airway integrity and supports symptomatic relief.

D. Obtain axillary temperatures:Using the axillary route avoids disturbing the oral cavity, making it a safe and appropriate method for monitoring temperature in a child with suspected or confirmed epiglottitis. It minimizes the risk of triggering airway complications.
