A nurse in an allergy clinic is caring for a client who has a history of seasonal allergy symptoms. The client had a radioallergosorbent test (RAST) completed on a previous visit. The nurse should recognize that an elevation in which of the following immunoglobulins indicates a positive result?
Immunoglobulin E (IgE)
Immunoglobulin M (IgM)
Immunoglobulin A (IgA)
Immunoglobulin G (IgG)
The Correct Answer is A
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 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 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.
