It is located within the bloodstream. The bloodstream contains extracellular fluid, not intracellular fluid.

It is the one containing hormones intended to balance red blood cell count. Hormones that regulate red blood cell count are not specific to the intracellular compartment.

It is the one for which capillary membranes become extra permeable during inflammation allowing certain proteins to move to tissues. This refers to the extracellular fluid (ECF) and interstitial fluid, not intracellular fluid.

Blocking the arterial walls from absorbing electrolytes: The respiratory system does not affect the absorption of electrolytes in this manner.

Preventing the absorption of sodium and potassium: The respiratory system does not regulate sodium and potassium absorption directly.

Regulating the excretion or reabsorption of H and HCO3: This function is performed by the kidneys, not the respiratory system.

Weight loss. Weight loss is typically associated with fluid volume deficit, not excess.

Low urine output. Low urine output is usually a sign of fluid volume deficit.

Poor skin turgor. Poor skin turgor is a sign of dehydration or fluid volume deficit.

Addison disease. Addison's disease is typically associated with hyperkalemia and hypermagnesemia due to adrenal insufficiency.

Milk-alkali syndrome. Milk-alkali syndrome usually results in hypercalcemia, not hypomagnesemia.

Rhabdomyolysis. Rhabdomyolysis can cause hyperkalemia and hypocalcemia, but hypomagnesemia is not a primary feature.

Excessive H⁺ ion loss due to severe vomiting: Severe vomiting typically leads to metabolic alkalosis, not acidosis.

Hyperventilation secondary to a panic attack: Hyperventilation leads to respiratory alkalosis due to low PaCO2 levels.

Increased renal HCO3 excretion due to kidney disease: Increased renal excretion of bicarbonate would lead to metabolic acidosis, not respiratory acidosis.

Neurological symptoms such as numbness and tingling of the hands and feet: Numbness and tingling are more commonly associated with electrolyte imbalances like hypocalcemia or hypokalemia, not hypernatremia.

Gastrointestinal symptoms such as abdominal pain and diarrhea: Hypernatremia typically causes neurological, not gastrointestinal, symptoms.

Gastrointestinal symptoms such as abdominal pain and constipation: Gastrointestinal symptoms are not the primary manifestation of hypernatremia.

Cells that release histamine during the inflammatory response. Cells that release histamine during inflammation are mast cells, not phagocytic cells.

Cells in the immune system with four-part receptors shaped like a Y. Cells with Y-shaped receptors are B cells, which produce antibodies, not phagocytes.

Cells in the immune system with two chains. T cells have two-part receptors but are not classified as phagocytes.

Innate immunity. While innate immunity includes the inflammatory response, it refers to the broader set of nonspecific defenses the body uses against pathogens.

Adaptive or acquired immunity. Adaptive immunity is the body's specific immune response, involving T cells and B cells, not the immediate reaction to tissue injury.

Vasodilation. Vasodilation is a part of the inflammatory response, but it is not the full process.

Heterozygous. Heterozygous means having two different alleles for a gene (one from each parent).

Dominant. Dominant refers to an allele that expresses its traits even if only one copy is present.

Recessive. Recessive refers to an allele that only expresses its traits when two copies are present, but this term doesn't describe the inheritance pattern itself.
