A nurse is auscultating a client’s lung sounds and identifies crackles in the left lower lobe. Which of the following interventions should the nurse take?
A.
Place the client on bed rest in supine position.
B.
Repeat auscultation after asking the client to breathe deeply and cough.
C.
Prepare to administer antibiotics.
D.
Instruct the client to limit fluid intake to less than 2,000 mL/day.
The correct answer and Explanation is :
The correct answer is B. Repeat auscultation after asking the client to breathe deeply and cough.
Explanation
Crackles (also known as rales) are abnormal lung sounds that may indicate fluid in the alveoli, possibly due to conditions such as pneumonia, heart failure, or pulmonary edema. When crackles are auscultated in a specific lobe, it suggests localized changes in lung function.
In this scenario, it is essential first to gather more information before making any decisions about treatment. By asking the client to take deep breaths and cough, the nurse can facilitate lung expansion and promote the clearance of secretions. This maneuver can sometimes temporarily clear or diminish the crackles if they are due to the presence of mucus or fluid that can be mobilized. After this intervention, the nurse should repeat the auscultation to assess whether there is any change in the lung sounds.
The other options are less appropriate in this context:
- A. Place the client on bed rest in supine position: This may not be beneficial, as it could lead to further pooling of secretions in the lungs. Encouraging mobility and positioning that promotes lung expansion is generally more effective.
- C. Prepare to administer antibiotics: While crackles can indicate infection, antibiotics should only be administered if a bacterial infection is confirmed or strongly suspected. Diagnosis must be established based on clinical assessment and further diagnostic tests.
- D. Instruct the client to limit fluid intake to less than 2,000 mL/day: Limiting fluid intake is not a routine intervention for crackles and could be detrimental, especially if the client is dehydrated or has conditions requiring adequate hydration.
In summary, the best immediate intervention is to repeat the auscultation after the client breathes deeply and coughs, allowing for better assessment of the lung sounds and potential resolution of the crackles.
