The nurse correlates which rationale with the administration of aspirin to the client experiencing angina-like chest pain?

Choice A reason: Vasopressin (Desmopressin) is not primarily used to decrease blood pressure. It is an antidiuretic hormone that helps manage diabetes insipidus by reducing urine output. While vasopressin can have vasoconstrictive effects, its primary role in this context is to control urine production, not blood pressure.

Choice B reason: The primary therapeutic outcome of vasopressin (Desmopressin) in a patient with diabetes insipidus is to decrease urine output. Diabetes insipidus leads to excessive urine production and dehydration. Vasopressin acts on the kidneys to increase water reabsorption, thereby reducing urine volume and helping to maintain fluid balance.

Choice C reason: Level of consciousness is not a direct therapeutic outcome of vasopressin (Desmopressin). While managing fluid balance can indirectly affect a patient's overall condition and well-being, vasopressin specifically targets the kidneys to reduce urine output and does not have a direct impact on consciousness levels.

Choice D reason: Specific gravity refers to the concentration of solutes in the urine. While vasopressin can affect the specific gravity by concentrating the urine and reducing volume, the primary therapeutic goal is to manage urine output in patients with diabetes insipidus. The focus is on reducing the excessive urine production rather than altering specific gravity.

Choice A reason: The regulation of water balance by the kidneys involves maintaining the appropriate volume and concentration of body fluids. By taking daily weights, nurses can assess fluid retention or loss, while monitoring intake and output (I&O) helps track fluid balance. Specific gravity measures the concentration of urine, which provides information about the kidneys' ability to concentrate or dilute urine. These interventions directly relate to the kidneys' role in regulating water balance.

Choice B reason: Regulation of acid-base balance by the kidneys involves maintaining the proper pH levels in the blood through excretion or retention of hydrogen ions and bicarbonate. While important, this function is not the primary focus of interventions like daily weights, I&O, and specific gravity monitoring, which are more related to water balance.

Choice C reason: The regulation of blood pressure by the kidneys is achieved through the renin-angiotensin-aldosterone system, which controls blood volume and systemic vascular resistance. Although fluid balance can indirectly affect blood pressure, the specific interventions mentioned are more directly related to water balance than blood pressure regulation.

Choice D reason: Regulation of metabolic wastes involves the kidneys filtering and excreting waste products from the blood. This function is vital for overall health, but interventions like daily weights, I&O, and specific gravity monitoring are more focused on assessing fluid balance rather than directly measuring waste elimination.
