A patient is admitted to the hospital with symptoms consistent with a right hemisphere stroke. Which neurovascular assessment requires immediate intervention by the nurse?

Choice A reason: The humoral immune response is mediated by B cells that produce antibodies against specific antigens. However, this response is not the main problem in AIDS, because B cells are not directly affected by the human immunodeficiency virus (HIV) that causes AIDS. Therefore, this choice is incorrect.

Choice B reason: The cellular immune response is mediated by T lymphocytes that activate other immune cells, such as macrophages, to destroy infected or abnormal cells. This response is the main problem in AIDS, because HIV infects and destroys CD4+ T cells, which are essential for coordinating the cellular immunity. As a result, the client becomes susceptible to opportunistic infections, such as Pneumocystis jiroveci pneumonia. Therefore, this choice is correct.

Choice C reason: Bone marrow suppression of white blood cells can cause immunodeficiency, but it is not the primary cause of AIDS. Bone marrow suppression can occur as a side effect of some drugs or treatments, such as chemotherapy or radiation therapy, but it is not directly caused by HIV. Therefore, this choice is incorrect.

Choice D reason: Exposure to multiple environmental infectious agents can challenge the immune system, but it does not necessarily cause it to fail. The immune system can adapt and respond to different pathogens, unless it is compromised by an underlying condition, such as AIDS. Therefore, this choice is incorrect.

The client has inhaled smoke, which can cause respiratory problemssuch as airway obstruction, bronchospasm, and pulmonary edema. The client also has initial fluid shifts, which can lead to electrolyte imbalancesuch as hyponatremia, hyperkalemia, and metabolic acidosis.

Choice A: inhaled smoke - respiratory problems

This is a correct choice. Inhaled smoke can damage the respiratory system by causing inflammation, edema, and carbon monoxide poisoning.

Choice B: initial fluid shifts - electrolyte imbalance

This is a correct choice. Initial fluid shifts occur when fluid moves from the intravascular space to the interstitial space due to increased capillary permeability. This can result in electrolyte imbalance such as low sodium, high potassium, and low bicarbonate levels.

Choice C: increased cardiac output - high blood sodium levels

This is an incorrect choice. Increased cardiac output is not a condition that occurs in burn patients. High blood sodium levels are not a common finding in burn patients either. High blood sodium levels can occur due to dehydration or excessive sodium intake.

Choice D: decreased catecholamines - hypometabolism

This is an incorrect choice. Decreased catecholamines are not a finding in burn patients. Catecholamines are hormones that increase heart rate, blood pressure, and metabolism in response to stress. Burn patients have increased catecholamines due to pain and tissue injury. Hypometabolism is also not a condition that occurs in burn patients. Hypometabolism is a state of low metabolic rate that can occur due to starvation, hypothyroidism, or hypothermia. Burn patients have increased metabolism due to increased energy demands for wound healing and thermoregulation.
