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: A rosebud like stoma orifice is a normal appearance for a new colostomy, indicating that the stoma is healthy and not in distress.
Choice B reason: Red drainage from a stoma can be normal, especially in the early postoperative period, as the stoma may ooze a small amount of blood. However, if the drainage is excessive or persistent, it should be reported.
Choice C reason: A shiny, moist stoma is also a sign of a healthy stoma. The stoma should be moist and have a pink or red color, similar to the inside of the mouth.
Choice D reason: A purplish colored stoma indicates compromised blood flow and is a sign of ischemia. This is a serious complication that requires immediate medical attention to prevent tissue death.
Correct Answer is B
Explanation
Choice A reason: Tennis involves abrupt lateral movements and may not be suitable for someone with low back pain, as it can exacerbate the condition.
Choice B reason: Swimming is a low impact exercise that can help strengthen the back muscles without putting additional stress on the spine, making it an ideal choice for individuals with low back pain.
Choice C reason: The option "Custom: NUR 224G Sec 2 Blandon Final" does not refer to a specific exercise and seems to be an error or unrelated text.
Choice D reason: Rowing can be strenuous on the lower back due to the repetitive motion and the need for strong core engagement, which might not be recommended for acute low back pain.
