A client has received vasopressin for diabetes insipidus. Which assessment finding indicates the most therapeutic response to this therapy?
Urine output has increased; specific gravity has decreased.
Urine output has increased; specific gravity has increased.
Urine output has decreased; specific gravity has decreased.
Urine output has decreased; specific gravity has increased.
The Correct Answer is D
Choice A rationale: This is a sign of worsening diabetes insipidus.
Choice B rationale: This shows signs of overhydration, as urine output is high and specific gravity is high.
Choice C rationale: This is a sign of worsening diabetes insipidus.
Choice D rationale: Vasopressin is a hormone that helps the kidneys retain water and concentrate urine. Diabetes insipidus is a condition where the body does not produce enough vasopressin or does not respond to it, resulting in excessive urination and diluted urine. The goal of vasopressin therapy is to reduce urine output and increase urine concentration, which indicates that the kidneys are functioning properly and the body is hydrated.

Choice B rationale: Hypospadias is a congenital defect in which the opening of the urethra is on the underside of the penis, not at the tip.
Choice C rationale: Phimosis is a condition in which the foreskin of the penis cannot be retracted fully, leading to inflammation and infection.
Choice D rationale: Orchitis is an inflammation of one or both testicles, usually caused by an infection.
Correct Answer is B
Explanation
Choice A rationale: this corresponds with 25 mg which is lower than the prescribed amount.
Choice B rationale: To answer this question, we need to use the formula: volume (mL) = dose (mg) / concentration (mg/mL). We plug in the given values: volume (mL) = 35 mg / 25 mg/mL. We simplify the fraction: volume (mL) = 7/5. We convert the fraction to a
decimal: volume (mL) = 1.4. Therefore, the nurse should administer 1.4 mL of promethazine.
Choice C rationale: this corresponds with 37.5 mg which is too high.
Choice D rationale: this corresponds with 17.5 mg which is too low.
