The nurse assesses that a client has nailbed clubbing. Which additional information is consistent with this finding?
Absent deep tendon reflexes.
Capillary refill less than 3 seconds.
3+ peripheral dependent edema.
Oxygen saturation of 85%.
The Correct Answer is D
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.

Correct Answer is D
Explanation
A. Palpating the radial pulses might not detect irregularities in pulse rate or rhythm as effectively as auscultation at the apical site.
B. Listening over the carotid artery may be useful in certain situations but is not the preferred method for assessing overall pulse rate.
C. Feeling the dorsalis pedis and posterior tibialis pulses provides information about peripheral circulation but does not assess the overall heart rate.
D. Auscultating the apical pulse is the most accurate method to assess the pulse rate, especially in clients with cardiovascular disease, as it provides direct measurement of heart activity.
Correct Answer is D
Explanation
A. Tympany indicates the presence of gas within the intestines. This would not be expected over the liver area if there is hepatomegaly.
B. This is not an expected finding in hepatomegaly. Tympany is associated with air-filled structures, which would not be present over an enlarged liver.
C. A hollow sound is also indicative of air-filled organs like the intestines. It is not a sign of hepatomegaly, which would be characterized by dullness on percussion.
D. Dullness upon percussion outside the costal margins suggests an enlarged liver (hepatomegaly). This is due to the liver becoming larger and filling the space that normally contains air-filled organs like the intestines.
