When auscultating over the apex of the client's lung field, what breath sound should the nurse expect to hear?

Bronchovesicular

Vesicular

Bronchial

Crackles

Answer and Explanation

The Correct Answer is B

B. Heard over most of the lung fields, except for the major bronchi and the trachea.

Low intensity and pitch, with a longer inspiratory phase than expiratory phase. They are softer and more breezy in quality. Vesicular breath sounds are heard over the peripheral lung fields, including the apex (top) of the lungs.

A. Heard over the major bronchi, which are near the sternum and between the scapulae. They are of intermediate intensity and pitch, with equal inspiration and expiration phases. They are typically heard in the 1st and 2nd intercostal spaces along the sternal border and between the scapulae.

C. Heard over the trachea and larynx.

Characteristics: High intensity and pitch, with a short inspiratory phase and a longer expiratory phase. They are louder and harsher in quality, resembling the sound of air blowing through a hollow pipe.

D. Crackles are abnormal breath sounds that can be fine or coarse.

Fine crackles are high-pitched, short, popping sounds heard during inspiration, often due to fluid in the small airways or alveoli.

Coarse crackles are loud, low-pitched, bubbling sounds heard during inspiration, typically due to the presence of secretions in the larger airways.

Correct Answer is A

Explanation

A. One of the primary reasons for administering IV fluids is to correct imbalances in fluid volume or electrolyte concentrations. Examples include correcting dehydration, restoring electrolyte levels (such as sodium, potassium), and addressing fluid losses due to vomiting, diarrhea, or excessive sweating.

B. IV fluids are typically used to increase intravascular volume rather than decrease it. In conditions such as hypovolemia (low blood volume), IV fluids are administered to restore blood volume and improve circulation.

C. Third spacing refers to the abnormal accumulation of fluid in interstitial spaces, which can occur in conditions like sepsis, burns, or trauma. IV fluids are not typically administered to increase third spacing; rather, treatment aims to redistribute fluids and improve fluid balance.

D. Enteral fluids are fluids administered directly into the gastrointestinal tract (via oral or tube feeding). IV fluids are administered directly into the bloodstream and are used when enteral administration is not feasible or sufficient.

A. Presence of pain B. Presence of saliva C. Gag reflex D. Condition of the skin

Correct Answer is C

Explanation

C. This reflex is an important protective mechanism that prevents objects from entering the throat and causing choking. Assessing the gag reflex before oral care can help ensure the safety of the client, especially if they have difficulty swallowing or are at risk for aspiration.

A. It's important to assess if the client is experiencing any pain, as oral care procedures can sometimes cause discomfort, especially if the client has oral lesions or sensitive gums. However, it is not a priority.

B. Presence of saliva: Saliva is essential for oral health, as it helps to cleanse the mouth and buffer acids produced by bacteria. Assessing the amount of saliva can indicate the overall oral hydration status and potential risk of dry mouth (xerostomia).

D. assessing the condition of the skin around the mouth and on the lips is important. It can reveal issues such as dryness, cracking, lesions, or signs of infection but not directly related to oral care.
