A nurse is assessing a client with suspected hypovolemic shock. Which finding is the earliest indicator of this condition?

Choice A reason: Urinary retention, the inability to empty the bladder, is unlikely with diuretics, which increase urine output. Diuretics reduce fluid volume by enhancing renal excretion, not causing retention. This concern is irrelevant, as the client’s increased output suggests effective diuresis, not bladder dysfunction or obstruction.

Choice B reason: Decreased fluid volume risk is a primary concern with diuretics, which increase urine output, potentially causing dehydration or electrolyte imbalances (e.g., hypokalemia). Education on fluid intake, monitoring weight, and recognizing dehydration symptoms is critical to prevent hypovolemia, ensuring safe diuretic use and maintaining physiological stability.

Choice C reason: Altered skin integrity may occur secondary to dehydration (dry skin) but is not the primary concern with diuretics. The main risk is fluid volume loss, which can lead to systemic complications like hypotension. Education should focus on fluid balance rather than skin, which is a secondary issue.

Choice D reason: Altered urinary elimination, such as incontinence, is not the primary concern, as diuretics increase output, not disrupt elimination patterns. While frequent urination may occur, the critical issue is fluid volume loss, which poses greater risks like dehydration or electrolyte imbalances, necessitating education on fluid management.

Choice A reason: Sensible water loss refers to measurable fluid loss, like urine or sweat. The client’s symptoms, including high serum sodium (153 mEq/L), suggest hypernatremia due to water loss, but sensible losses like urine are reduced (decreased urine output). Insensible losses better explain the unmeasurable fluid deficit in this scenario.

Choice B reason: Major magnesium losses cause hypomagnesemia, leading to tremors or arrhythmias, not typically confusion or hypernatremia. The client’s high sodium and dehydration symptoms point to water loss, not magnesium. Magnesium levels are not provided, and the symptoms align more with fluid imbalance than magnesium deficiency.

Choice C reason: Insensible water loss, from skin and respiration, is unmeasurable and can lead to hypernatremia (serum sodium 153 mEq/L) due to concentrated blood. Dry mucous membranes, decreased urine output, and confusion indicate dehydration from water loss, consistent with insensible losses in elderly patients with reduced thirst perception.

Choice D reason: Low potassium levels (hypokalemia) cause muscle weakness and arrhythmias, not hypernatremia or confusion. The client’s high sodium and dehydration symptoms point to water loss, not potassium imbalance. Potassium levels are not provided, but the clinical picture supports insensible water loss as the primary issue.
