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 A
Explanation
Choice A reason: Right lower quadrant.
McBurney's point is located in the right lower quadrant of the abdomen, which is one-third of the distance from the anterior superior iliac spine to the umbilicus. This is the area where tenderness is most likely to be maximal in cases of acute appendicitis.
Choice B reason: Left lower quadrant
The left lower quadrant is not typically associated with appendicitis pain, as the appendix is located in the right lower quadrant of the abdomen.
Choice C reason: Right upper quadrant
The right upper quadrant is generally associated with other conditions such as gallbladder issues, not appendicitis.
Choice D reason: The left upper quadrant
The left upper quadrant is also not associated with appendicitis pain, as it is on the opposite side of the typical location of the appendix.
Correct Answer is B
Explanation
Choice A reason: Establishing short-term, realistic goals is important, but it should come after assessing the client's current knowledge. Goals should be tailored to the individual's needs and understanding.
Choice B reason: Assessing the client's current knowledge about managing diabetes is crucial as the first step. This allows the nurse to identify any gaps in understanding and to provide education that is specific to the client's needs.
Choice C reason: Providing access to a video about diabetes can be a useful educational tool, but it should not be the first action. The content of the video may not address the client's specific questions or misconceptions.
Choice D reason: Evaluating the effectiveness of the client's admission teaching plan is an ongoing process and should be done after initial education and interventions have been provided.
