The nurse assesses that a client has nailbed clubbing. Which additional information is consistent with this finding?

A. Absent deep tendon reflexes are not typically associated with nailbed clubbing. While reflexes may be diminished in some conditions, they are not commonly related to the pathophysiology behind clubbing. B. A capillary refill time of less than 3 seconds is a normal finding and does not align with clubbing, which often indicates chronic hypoxia or systemic conditions such as heart or lung disease. C. Peripheral dependent edema refers to swelling in the lower extremities, which can be associated with circulatory problems, but it is not directly linked to nailbed clubbing. Edema is more common in conditions like heart failure or kidney disease. D. A low oxygen saturation of 85% is consistent with conditions that cause chronic hypoxia, such as chronic lung disease or congenital heart disease. Chronic low oxygen levels can lead to nailbed clubbing as a compensatory response to inadequate oxygenation.
