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 ["A","B","D"]
Explanation
Choice A reason: Enlarged distal extremities are a classic sign of acromegaly due to the overproduction of growth hormone, which affects the growth plates in the bones.
Choice B reason: Coarse facial features, including a protruding jaw and brow, enlarged nose, and thickened lips, are common in acromegaly due to the excessive growth of facial bones and soft tissues.
Choice C reason: Loss of color discrimination is not typically associated with acromegaly. This symptom may be related to other conditions affecting the optic nerve or the brain.
Choice D reason: Hepatomegaly, or an enlarged liver, can occur in acromegaly as a result of increased growth factor effects on the liver.
Choice E reason: Moon face is associated with conditions that lead to corticosteroid excess, such as Cushing's syndrome, but can also appear in acromegaly due to soft tissue swelling.
