A client with a closed head injury demonstrates signs of syndrome of inappropriate antidiuretic hormone (SIADH). Which additional finding should the nurse expect to obtain?
Weight gain of 2 pounds (0.91 kg) in one day.
Fremitus over the chest wall.
Serum sodium of 150 mEq/L (150 mmol/L).
Urine specific gravity of 1.004.
The Correct Answer is A
Choice A reason: Weight gain of 2 pounds (0.91 kg) in one day is a sign of fluid retention, which occurs in SIADH due to excessive secretion of antidiuretic hormone (ADH). ADH causes the kidneys to reabsorb water and reduce urine output, leading to hyponatremia and hypervolemia.
Choice B reason: Fremitus over the chest wall is a sign of increased vibration or air movement in the lungs, which can indicate pneumonia, bronchitis, or pleural effusion. These are not related to SIADH, but may be complications of head injury or fluid overload.
Choice C reason: Serum sodium of 150 mEq/L (150 mmol/L) is a sign of hypernatremia, which is a high level of sodium in the blood. This is the opposite of what happens in SIADH, where sodium levels are low due to dilution by excess water.
Choice D reason: Urine specific gravity of 1.004 is a sign of diluted urine, which indicates low concentration of solutes in the urine. This is also the opposite of what happens in SIADH, where urine is concentrated and has a high specific gravity.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C","dropdown-group-3":"D","dropdown-group-4":"A"}
Explanation
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.
Correct Answer is B
Explanation
Choice A reason: This is incorrect because the humoral immune response involves B cells that produce antibodies against specific antigens. However, AIDS affects the cellular immune response, which involves T cells that activate other immune cells and directly kill infected cells.
Choice B reason: This is correct because AIDS is caused by human immunodeficiency virus (HIV), which infects and destroys CD4+ T cells, also known as helper T cells. These cells are essential for initiating and regulating both humoral and cellular immunity. Without enough CD4+ T cells, the body cannot mount an effective response against pathogens, especially opportunistic infections that take advantage of a weakened immune system.
Choice C reason: This is incorrect because bone marrow suppression of white blood cells is not a direct consequence of AIDS. However, some drugs used to treat AIDS, such as zidovudine, may cause bone marrow suppression as a side effect.
Choice D reason: This is incorrect because exposure to multiple environmental infectious agents does not cause AIDS. However, people with AIDS are more susceptible to infections from various sources due to their impaired immune system.
