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 C
Explanation
Choice A: Sleepy, but arousing when the name is called
Feeling sleepy after receiving morphine is a common side effect. However, the fact that the client can be aroused when their name is called suggests that this is not necessarily an adverse effect.
The nurse should continue monitoring the client but may not consider this as a significant adverse reaction.
Choice B: Pain level of 6 on a scale from 0 to 10
Pain relief is one of the intended effects of morphine. Therefore, experiencing pain reduction is not an adverse effect.
The nurse would likely view this as a positive response to the medication.
Choice C: Respiratory rate of 8/min
A respiratory rate of 8 breaths per minute is significantly low and indicates respiratory depression, which is a serious adverse effect of morphine.
The nurse should be concerned about this finding and take appropriate action.
Choice D: SaO2 94%
An oxygen saturation (SaO2) level of 94% is within the normal range (usually 95% or higher). It is unlikely to be directly related to morphine administration.
While this value is not concerning, the nurse should continue monitoring the client's oxygen saturation.
Correct Answer is C
Explanation
Choice A reason: Acute pain is expected with a fracture but does not specifically indicate impaired venous return.
Choice B reason: Ecchymosis, or bruising, can occur with a fracture due to bleeding into the tissue but is not a direct indicator of venous return issues.
Choice C reason: Increasing edema is a sign of impaired venous return as it indicates a buildup of fluid in the tissues, which can occur if the veins are not effectively returning blood to the heart.
Choice D reason: A diminishing distal pulse could indicate arterial impairment rather than venous return issues.
