A nurse is assessing a client who has chronic bronchitis. Which of the following percussion sounds should the nurse expect?
Dullness
Tympany
Resonance
Flatness
The Correct Answer is C
Choice A reason: Dullness on percussion typically indicates increased lung density, such as in conditions where lung tissue is consolidated or fluid-filled. This sound is heard in cases of: Pneumonia (due to alveolar consolidation) Pleural effusion (fluid in the pleural space) Lung tumors (solid masses in lung tissue) Since chronic bronchitis is primarily an airway disease characterized by inflammation and mucus production rather than lung consolidation or fluid accumulation, dullness is not an expected finding..
Choice B reason: Tympany is usually heard over air-filled structures and is not a percussion sound typically associated with chronic bronchitis.
Choice C reason:
Resonance is the normal percussion sound heard over healthy lung fields, indicating air-filled alveoli. Since chronic bronchitis does not cause significant air trapping or lung consolidation, percussion remains resonant rather than hyperresonant (as in emphysema) or dull (as in pneumonia). Thus, resonance is the expected finding in chronic bronchitis because the lung parenchyma remains relatively unaffected despite the chronic airway inflammation.
Choice D reason: Flatness is heard over very dense tissue, such as muscle or bone, and is not characteristic of chronic bronchitis.

Correct Answer is D
Explanation
Choice A reason: Dependent rubor, a reddish coloration of the skin that occurs when the legs are in a dependent position, can be a sign of PAD, indicating poor arterial flow.
Choice B reason: Foot ulcers may occur in individuals with PAD due to poor blood circulation and the inability of sores or injuries to heal properly.
Choice C reason: Rest pain is a symptom of advanced PAD and occurs due to insufficient blood flow to the limbs even at rest, often worsening at night when the legs are elevated.
Choice D reason: Intermittent claudication, characterized by pain and cramping in the legs during exercise that disappears after rest, is a hallmark symptom of PAD and results from inadequate blood flow during increased activity.
Correct Answer is B
Explanation
Choice A reason: This statement is incorrect. Synthetic casts typically dry much faster than plaster casts. Plaster casts can take 24 to 48 hours to fully harden, while synthetic casts made from materials like fiberglass or plastic can harden within a few hours.
Choice B reason: This is the correct statement. Synthetic casts are indeed lighter than plaster casts. They are made from materials like fiberglass, which is lighter than the traditional plaster of Paris used in plaster casts.
Choice C reason: This statement is incorrect. Plaster casts are generally heavier than synthetic casts. The weight of a cast can be an important consideration, especially for children or for those who may have difficulty managing a heavier cast.
Choice D reason: This statement is incorrect. Both plaster and synthetic casts require specialized equipment for application, but it is not specific to plaster casts. The application involves similar steps for both types, including the use of a stockinette, padding, and then the casting material itself.
