Question

CASE STUDY PROGRESS

You complete your assessment of G.S. You note she is dyspneic and has fine crackles throughout all lung fields posteriorly and in both lower lobes anteriorly, and coarse crackles over the large airways. She has O₂ on at 2 L per nasal cannula and her Spo₂ is 94%.

8. What is the significance of the fine and coarse crackles?

9. The nurse from the previous shift charted the following statement: “Fine and coarse crackles that clear with vigorous coughing.” Based on your knowledge of pathophysiology, determine the accuracy of this statement.

10. It is time to administer scheduled furosemide (Lasix) 60 mg intravenous push. What effect, if any, should furosemide have on G.S.’s breath sounds?

11. What action do you need to take before giving the furosemide?

Answer 1

8, when the airway is narrow due to mucous or fluid air being forced through the airway, that time fine and coarse crackles sound can be heard it occur during inspiration. fine crackers heard during late inspiration and coarse crackles during early inspiration. it was lounder, low pitched and long-lasting.
9, cough clear up the throat and clear the mucous and fluid from the airway. coughing change or clear the quality of coarse crackles. cough help to disappear fine and coarse crackles.
10, Furosemide relieve dyspnea. it lessens the excess fluid in the lungs and relives dyspnea. so there is no abnormal breath sounds and it clear fine and coarse crackles.
11, Monitor patient liver, kidney function, and serum electrolyte, uric acid, and serum glucose level. Assess patient vital signs and weight and intake and output before administering furosemide.
