Review Roach's Introductory Clinical Pharmacology 11th Edition - Uterine Drugs related questions and content

A client has received a special formulation of oxytocin for intranasal use. The nurse understands that the rationale for using this formulation of the drug involves which effect?

  • A. Antistimulating properties on the uterus
  • B. Diuretic effect
  • C. Stimulation of the milk ejection reflex
  • D. Control of antepartum bleeding
Correct Answer: C

Rationale: Oxytocin, when administered intranasally, stimulates the milk ejection (milk letdown) reflex. Oxytocin has uterine-stimulating properties, not antistimulating properties, on the uterus. Tocolytics have an antistimulating effect on the uterus. Oxytocin has an antidiuretic effect, which might lead to a danger of excessive fluid volume (water intoxication), and not a diuretic effect. Oxytocin is given IM during the third stage of labor to produce uterine contractions and control postpartum, and not antepartum, bleeding and hemorrhage.
