A nurse is caring for a client who has leukemia. The nurse understands that this condition is characterized by what type of neoplasia?

Choice A reason:

This is an incorrect answer because cardiogenic shock is a severe form of heart failure that occurs when the heart cannot pump enough blood to maintain adequate tissue perfusion and oxygenation, resulting in hypotension, tachycardia, oliguria, altered mental status, and cold and clammy skin.

Choice B reason:

This is an incorrect answer because pulmonary embolism is a condition in which a blood clot travels to the lungs and blocks one or more pulmonary arteries, causing sudden dyspnea, chest pain, hemoptysis, tachypnea, and hypoxia.

Choice C reason:

This is a correct answer because right-sided heart failure occurs when the right ventricle of the heart fails to pump blood effectively to the lungs, causing blood to back up in the systemic circulation and leading to fluid accumulation in the lungs, neck veins, and extremities.

Choice D reason:

This is an incorrect answer because left-sided heart failure occurs when the left ventricle of the heart fails to pump blood effectively to the body, causing blood to back up in the pulmonary circulation and leading to pulmonary congestion, dyspnea, orthopnea, coughing, and fatigue.

Choice A reason:

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

Choice B reason:

Type II hypersensitivity is not involved in RA, as it does not involve IgG or IgM antibodies or target cells.2

Choice C reason:

RA is caused by type III hypersensitivity, which involves the formation and deposition of immune complexes in the synovial membranes of the joints. This triggers complement activation, inflammation, and tissue damage.

Choice D reason:

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