Final Answer:
Rounded and enlarged fingers are indicative of chronic hypoxia, leading to structural changes in the fingertips, specifically an increase in connective tissue and blood vessels. This condition is commonly associated with respiratory disorders. Thus, the correct answer is option c) Clubbing
Step-by-step explanation:
Clubbing is a clinical sign characterized by the enlargement and rounding of the fingertips. In the context of a client with a respiratory disorder, this finding is indicative of chronic hypoxia. It is not directly related to acute hypoxemia, wheezing, or cyanosis. Clubbing is often associated with conditions such as chronic obstructive pulmonary disease (COPD), interstitial lung disease, or cystic fibrosis.
Clubbing occurs due to the proliferation of connective tissue and blood vessels in the nail beds, leading to changes in the normal angle between the nail and the nail bed. This alteration in the anatomy of the fingers is a result of prolonged inadequate oxygenation of peripheral tissues. Therefore, when a nurse observes rounded and enlarged fingers in a client with a respiratory disorder, it signifies a chronic lack of oxygen rather than acute events like wheezing or cyanosis.
In summary, the nurse documents the finding as "clubbing" to accurately reflect the observed physical manifestation associated with chronic hypoxia in the context of respiratory disorders.
Thus, the correct answer is option c) Clubbing
