A nurse is caring for a client who has Graves' disease. The nurse understands that this condition is caused by what type of hypersensitivity? (Select all that apply.)

Choice A reason:

Type I hypersensitivity is not involved in Graves' disease, as it does not involve IgE antibodies or mast cells.

Choice B reason:

Type II hypersensitivity is involved in Graves' disease, as it involves IgG antibodies that bind to the thyroid-stimulating hormone (TSH) receptors on the thyroid gland and stimulate the production of thyroid hormones. This leads to hyperthyroidism and manifestations such as goiter, exophthalmos, tachycardia, weight loss, or tremors.

Choice C reason:

Type III hypersensitivity is not involved in Graves' disease, as it does not involve immune complexes or complement activation.

Choice D reason:

Type IV hypersensitivity is not involved in Graves' disease, as it does not involve cytotoxic T cells or helper T cells.

Choice E reason:

Type V hypersensitivity is also involved in Graves' disease, as it involves the stimulation of target cells by antibodies that act as agonists for cell surface receptors. This leads to an increased function of the target organ or tissue.

Choice A reason:

Restricting fluid intake is not an action that the nurse should take for a client who has hypernatremia. Fluid restriction can worsen hypernatremia by increasing the concentration of sodium in the blood. Fluid intake should be increased or replaced with isotonic or hypotonic fluids to dilute sodium and correct hypernatremia.

Choice B reason:

Monitoring neurological status is an action that the nurse should take for a client who has hypernatremia. Hypernatremia can cause neurological symptoms such as confusion, agitation, seizures, coma, and death due to cellular dehydration and brain shrinkage. The nurse should assess the client's level of consciousness, orientation, memory, behavior, and reflexes regularly and report any changes or deterioration.

Choice C reason:

Administering hypotonic IV fluids is an action that the nurse should take for a client who has hypernatremia. Hypotonic fluids have a lower concentration of solutes than normal body fluids and can help lower serum sodium levels by moving water into the cells from the blood vessels. The nurse should administer hypotonic fluids slowly and carefully to avoid fluid overload or cerebral edema.

Choice D reason:

Encouraging foods high in sodium is not an action that the nurse should take for a client who has hypernat
