A client with a history of COPD is being assessed. When the nurse percusses the client's chest, which characteristic sound is expected?
Tympany
Hyperresonance
Resonance
Dullness
The Correct Answer is B
Choice a reason:
Tympany is a drum-like, resonant sound that is typically heard over air-filled structures, such as the gastric bubble, not the chest. It is not a sound associated with the lungs, especially in the context of COPD.
Choice b reason:
Hyperresonance is an abnormally loud, lower-pitched sound than normal resonance heard over hyperinflated areas of the lung, such as in cases of COPD. This is due to the increased air content within the lungs, often because of overdistension or destruction of alveolar tissue, as seen in emphysema, a common type of COPD.
Choice c reason:
Resonance is the normal sound heard over healthy lung tissue when percussed. However, in the case of COPD, particularly emphysema, the destruction of lung tissue leads to hyperinflation and thus a hyperresonant sound rather than the normal resonance.
Choice d reason:
Dullness is heard when fluid or solid tissue replaces air in the lung or occupies the pleural space, as in the case of pneumonia or pleural effusion. This is not characteristic of COPD, where there is an increase in air due to the breakdown of alveolar walls.

Correct Answer is B
Explanation
Choice A reason:
Diabetes mellitus is not typically associated with pitting edema unless it has led to a comorbid condition such as heart failure or kidney disease. Pitting edema is more commonly associated with fluid retention due to the body's inability to manage fluid balance, which is not a direct consequence of diabetes mellitus itself.
Choice B reason:
Liver disease, particularly cirrhosis, can lead to pitting edema. The liver's inability to produce albumin, a protein that helps maintain oncotic pressure in the blood vessels, and portal hypertension, which is an increase in the blood pressure within the portal vein system, can both contribute to the development of pitting edema.
Choice C reason:
End-stage renal disease can also cause pitting edema due to the kidneys' inability to excrete excess fluid. However, the edema associated with renal disease is often more generalized and not limited to the lower extremities.
Choice D reason:
Colon cancer is not typically associated with pitting edema unless it has metastasized and caused secondary complications that affect the liver or the heart. Pitting edema is not a direct symptom of colon cancer itself. 
Correct Answer is C
Explanation
Choice A Reason:
The dorsal aspect of the hand, rather than the finger pads, is more sensitive to temperature due to its thinner skin. Therefore, while the finger pads can detect temperature, they are not the best tool for this purpose.
Choice B Reason:
Vibrations, such as those produced by vocal fremitus, are typically assessed using the ulnar edge or the palmar aspect of the hand, not the finger pads. The finger pads are sensitive but do not provide the best surface for detecting vibrations.
Choice C Reason:
The finger pads are densely innervated and are the most sensitive part of the hand, making them ideal for palpating pulses. Pulses are subtle and require a fine touch to assess properly, which is why the finger pads are the preferred area for this assessment.
Choice D Reason:
Fremitus refers to the palpable vibrations transmitted through the bronchopulmonary tree to the chest wall as someone speaks. It is best felt with the ball of the hand or the ulnar edge, not the finger pads.
