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: Weighing the client daily is important for monitoring fluid balance but is not the most immediate action to prevent an Addisonian crisis.
Choice B reason: Restricting fluid intake is not appropriate for a client at risk for Addisonian crisis, as they may require increased fluids to prevent dehydration.
Choice C reason: This is the correct action. Clients with Addison's disease require corticosteroids to replace the hormones that their adrenal glands are not producing.
Choice D reason: Providing a low carbohydrate diet is not relevant to the prevention of an Addisonian crisis.
Correct Answer is ["A","B","C","D"]
Explanation
Choice A reason: Tingling in the arms can occur due to nerve compression caused by the herniated disc. This is a common symptom known as radicular pain, which can radiate from the neck down to the arms and hands.
Choice B reason: Shoulder pain is another expected finding, as the nerves affected by a cervical herniated disc can cause pain to radiate into the shoulders.
Choice C reason: Muscle spasms may be a reflexive response to the pain and inflammation caused by the herniated disc, as the body attempts to stabilize the affected area.
Choice D reason: A stiff neck can result from the muscle tension and reduced range of motion due to the pain and inflammation associated with a herniated cervical disc.
Choice E reason: Low back pain is not typically associated with a herniated cervical disc, as cervical discs are located in the neck region. Low back pain would be more indicative of a lumbar spine issue.
