Answer:
Yes, there is a need to assure the client that this is a normal reaction.
Explanation:
In the given case, it is the duty of a nurse to assure the patient that swelling takes place while performing intradermal vaccination. As with the administration of disease-specific antigens, the injected area inflames that generally takes place due to the development of antibodies against the presented antigens.
Thus, both the patient and the nurse need to be calm in such a situation and should leave the swelling open so that it can get heal by itself. In case, if one applies ice packs or rubs the affected area, it can enhance the condition and may result in more issues.

In a newly fertilized egg, the vitelline layer lifts away from the egg and hardens to form a fertilization envelope.
Therefore, the correct answer is Option A.
<h3>What is vitelline layer?</h3>
- Vitelline layer or vitelline membrane (VM) is a structure that surrounds the outer surface of the plasma membrane of an egg or ovum. In some organisms (e.g.: birds), the vitelline layer surrounds the extracellular yolk and the ovum.
- It is multilayered and functions to protect and give shape to the egg yolk and separate it from the egg white.
- VM consists of protein fibers and protein receptors necessary for sperm binding.
- As its function is to provide support and protection to the yolk, after fertilization, the vitelline layer gets hardened and separated from the yolk to form fertilization envelope.
