A nurse is teaching a newly licensed nurse about the differences between a plaster cast and a synthetic cast. Which of the following information should the nurse include in the teaching?
"Drying time is prolonged with a synthetic cast."
"A synthetic cast is lighter."
"A plaster cast weighs less."
"Application of a plaster cast requires specialized equipment."
The Correct Answer is B
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.

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 C
Explanation
Choice A reason: Metabolic acidosis is characterized by a low pH and a low HCO3. However, George's HCO3 is within normal range, indicating that metabolic acidosis is not the primary issue.
Choice B reason: Partially compensated metabolic acidosis would present with a low pH and a low HCO3, along with a low PaCO2 as the body attempts to compensate. George's PaCO2 is elevated, which is not consistent with this condition.
Choice C reason: George's high PaCO2 and near normal HCO3 suggest that his primary issue is respiratory acidosis. The body has begun to compensate by retaining HCO3, making it partially compensated.
Choice D reason: Uncompensated respiratory acidosis would present with an elevated PaCO2 and a normal HCO3. Since George's HCO3 is elevated, it indicates partial compensation.
