The nurse is preparing to administer oxytocin IV to a client after the delivery of her infant.
Which outcome should the nurse expect from the administration of oxytocin?

Return of the uterus to prepregnancy size.

Stimulation of uterine contractions.

Activation of the let-down reflex.

Expulsion of the placenta.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Oxytocin is not involved in returning the uterus to its prepregnancy size. Instead, it helps in uterine contractions, which facilitate the expulsion of the placenta and reduce postpartum bleeding. The process of uterine involution, returning to prepregnancy size, is primarily managed by the natural decline of pregnancy hormones and autolysis of uterine tissue.

Choice B rationale

Oxytocin stimulates uterine contractions, which is its primary function during labor and after delivery. These contractions help deliver the baby during labor and facilitate the expulsion of the placenta. After delivery, oxytocin continues to induce contractions to minimize postpartum hemorrhage and aid uterine involution.

Choice C rationale

Oxytocin can activate the let-down reflex for breastfeeding, but it is not the primary expected outcome when administered IV after delivery. The main goal post-delivery is to manage uterine contractions to prevent hemorrhage and assist in expelling the placenta.

Choice D rationale

While oxytocin assists in expelling the placenta by stimulating contractions, this is not its primary use post-delivery. The placenta typically detaches and is delivered shortly after birth. Oxytocin's main role after delivery is to continue stimulating contractions to reduce bleeding and help the uterus return to a non-pregnant state.

Correct Answer is A

Explanation

Choice A rationale

Checking serum human chorionic gonadotropin (hCG) levels is the appropriate action. hCG levels can help determine the viability of the pregnancy. Decreasing hCG levels may indicate a non-viable pregnancy, while increasing levels suggest a viable pregnancy.

Choice B rationale

Verifying the date of the last menstrual cycle is important but not the priority action in this scenario. While it can provide information on gestational age, it does not directly address the concern of vaginal bleeding.

Choice C rationale

Inquiring about the last occurrence of intercourse is not directly related to assessing the cause of vaginal bleeding. It may provide additional history but does not address the immediate concern.

Choice D rationale

Repeating a urine pregnancy test is not necessary in this context. The client is already known to be pregnant, and a urine test will not provide additional information regarding the cause of the bleeding.

Correct Answer is ["2.3"]

Explanation

Step 1 is to convert the child's weight from pounds to kilograms. 16 pounds ÷ 2.2 = 7.3 kg.

Step 2 is to calculate the total daily dose in mg. 25 mg/kg × 7.3 kg = 182.5 mg.

Step 3 is to determine the dose per administration, divided by 2 since the dose is given every 12 hours. 182.5 mg ÷ 2 = 91.25 mg.

Step 4 is to convert the dose from mg to mL using the concentration of the medication. 91.25 mg ÷ (200 mg/5 mL) = 91.25 ÷ 40 = 2.3 mL per dose. The answer is 2.3 mL.
