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)

Answer and Explanation

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 D

Explanation

Choice A reason: Humidifying the client's room can help maintain mucous membrane integrity and prevent respiratory infections, which is crucial for a client with a low WBC count.

Choice B reason: Replacing the water in flower vases daily can prevent the growth of bacteria, reducing the risk of infection for an immunocompromised client.

Choice C reason: Cleaning dentures in a denture cup is a standard infection control practice that helps maintain oral hygiene and prevent infections.

Choice D reason: Serving cooked fruit with meals reduces the risk of transmitting infections that can be associated with raw fruits, which is important for a client with neutropenia.

A. The blood has been infusing steadily for 5 hours with no client symptoms. B. Medication is being administered IV through the injection site closest to the client. C. The packed RBCs are connected by Tubing to normal saline. D. The drip chamber with filter is filled completely with blood.

Correct Answer is C

Explanation

Choice A reason: The blood should not be infusing for 5 hours as transfusions of packed RBCs should be completed within 2 to 4 hours to minimize the risk of bacterial growth and transfusion reactions.

Choice B reason: Medications should not be administered through the same IV line as blood products due to the risk of reactions and interactions.

Choice C reason: The packed RBCs are indeed connected by Tubing to normal saline, which is used to keep the line open and prevent clotting.

Choice D reason: The drip chamber should not be filled completely with blood as it is necessary to monitor the drip rate and to ensure that air does not enter the line.
