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 reason: This choice is incorrect as painless, raised purple nodules on the hard palate are not typically indicative of squamous cell carcinoma.
Choice B reason: This choice is incorrect because a small macule with a yellow-brown scale does not describe squamous cell carcinoma, which often presents as a firm nodule with a scaly crust.
Choice C reason: This choice is correct. Squamous cell carcinoma can present as a firm nodule with a hard, scaly crust on the skin.
Choice D reason: Yellow white patches of growth on the tongue are more indicative of conditions such as oral leukoplakia, not squamous cell carcinoma.
Correct Answer is B
Explanation
Choice A reason: Assessing the cranial nerves is important, but it is not the immediate next step after implementing droplet precautions for suspected bacterial meningitis.
Choice B reason: Decreasing environmental stimuli can help reduce the risk of seizures and is a supportive measure for a patient with suspected bacterial meningitis.
Choice C reason: Closing the room is part of implementing droplet precautions but is not an action that needs to be initiated by the nurse as it should already be in place.
Choice D reason: Administering an antipyretic may be necessary if the patient has a fever, but it is not the immediate next action after droplet precautions.
