a rise in plasma osmolality
B
stimulation of the baroreceptors
C
an increase in potassium levels in the ICF

an increase in ECF water concentration
Verified step by step guidance1
Understand the role of antidiuretic hormone (ADH): ADH is crucial for regulating water balance in the body by controlling the amount of water reabsorbed by the kidneys.
Identify the primary function of ADH: It helps to concentrate urine and reduce water loss, thus maintaining plasma osmolality.
Define plasma osmolality: Plasma osmolality refers to the concentration of solutes in the blood. A rise in plasma osmolality indicates a higher concentration of solutes, which typically triggers the release of ADH to conserve water.
Consider the role of osmoreceptors: Osmoreceptors are specialized cells that detect changes in plasma osmolality. When osmolality rises, these receptors stimulate the release of ADH.
Evaluate the options: A rise in plasma osmolality is the most direct stimulus for ADH release, as it signals the need to conserve water and restore balance. Other options like baroreceptor stimulation or changes in potassium levels do not directly trigger ADH release in the same way.
