A teenage client is admitted to the emergency department following a bee sting. The client arrives with a body rash and 30 minutes later becomes short of breath.
The client's vital signs are a heart rate of 130 beats/minute, respirations of 40 breaths/minute, and a blood pressure of 90/52 mm Hg. The client is exhibiting clinical manifestations of which type of immune reaction?

The correct answer is choiceb. Identify the client using 2 client identifiers,c. Perform hand hygiene,e. Don gloves,f. Check the skin around the face, andg. Assess respiratory function.

Choice A rationale:

Determining if the client needs to go to the bathroom is not directly related to the immediate preparation for oxygen administration. However, it can be considered as part of overall patient comfort and care.

Choice B rationale:

Identifying the client using 2 client identifiers is crucial to ensure the correct patient is receiving the correct treatment, which is a standard safety protocol in healthcare settings.

Choice C rationale:

Performing hand hygiene is essential to prevent the spread of infection and maintain a sterile environment.

Choice D rationale:

Brushing the client’s teeth is not a necessary step before applying a simple face mask for oxygen administration. It is more related to general oral hygiene.

Choice E rationale:

Donning gloves is important to protect both the nurse and the patient from potential contamination and infection.

Choice F rationale:

Checking the skin around the face is important to ensure there are no existing sores or irritations that could be exacerbated by the mask.

Choice G rationale:

Assessing respiratory function is critical to determine the patient’s baseline respiratory status and to monitor the effectiveness of the oxygen therapy.

Choice A rationale:

Autoimmune responses occur when the immune system mistakenly attacks the body's own tissues. They are not typically triggered by allergens like bee stings.

Autoimmune responses often develop slowly over time and present with symptoms related to the specific tissues being attacked.

The rapid onset of symptoms in this case, along with the specific symptoms of rash, shortness of breath, and low blood pressure, are not characteristic of an autoimmune response.

Choice B rationale:

Type II hypersensitivity reactions involve antibodies that target and destroy cells or tissues. These reactions often take hours or days to develop, rather than minutes.

Examples of type II hypersensitivity reactions include transfusion reactions, hemolytic disease of the newborn, and some autoimmune diseases.

The rapid onset of symptoms in this case is not consistent with a type II hypersensitivity reaction.

Choice C rationale:

Cell-mediated hypersensitivity reactions involve T cells that directly attack cells or tissues. These reactions typically take 1-3 days to develop.

Examples of cell-mediated hypersensitivity reactions include contact dermatitis (e.g., poison ivy), graft-versus-host disease, and some drug reactions.

The rapid onset of symptoms in this case, as well as the specific symptoms of rash, shortness of breath, and low blood pressure, are not characteristic of a cell-mediated hypersensitivity reaction.

Choice D rationale:

IgE response hypersensitivity reactions are the most immediate type of allergic reaction.

They are mediated by immunoglobulin E (IgE) antibodies, which bind to mast cells and basophils.

When an allergen (like bee venom) cross-links IgE antibodies on mast cells, it triggers the release of histamine and other inflammatory mediators.

These mediators cause vasodilation, increased vascular permeability, smooth muscle contraction, and mucus secretion, leading to the characteristic symptoms of an allergic reaction.

The rapid onset of symptoms in this case, including rash, shortness of breath, and low blood pressure, are consistent with an IgE-mediated hypersensitivity reaction.
