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
Explanation
Choice A reason: Immunoglobulin E (IgE) is associated with allergic reactions. A RAST test measures the level of allergen specific IgE antibodies in the blood. An elevation in IgE indicates sensitization to a particular allergen and a positive result for the allergy.
Choice B reason: Immunoglobulin M (IgM) is usually the first antibody produced by the immune system when it detects an infection. It is not typically associated with the detection of allergies.
Choice C reason: Immunoglobulin A (IgA) plays a critical role in mucosal immunity and is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and the gastrointestinal tract, but it is not used as an indicator in RAST testing for allergies.
Choice D reason: Immunoglobulin G (IgG) is the most abundant type of antibody and is involved in the recognition and removal of pathogens. It is not specific to allergic response detection in RAST testing.
Correct Answer is A
Explanation
Choice A reason: Eating foods at room temperature can help reduce nausea because strong odors from hot foods can increase the feeling of nausea.
Choice B reason: Increasing unsaturated fats is not specifically related to managing nausea and may not be beneficial in this context.
Choice C reason: Drinking more liquids with meals can sometimes increase nausea; it's often recommended to drink fluids between meals instead.
Choice D reason: Eating smaller meals can help manage nausea because large meals can overwhelm the digestive system when it's sensitive due to treatment.
