One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because
It produces a prolapsed cord.
It increases maternal renal blood flow.
It decreases maternal blood pressure.
There is a reduction of placental blood flow.
The Correct Answer is D
Choice A reason:
A prolapsed umbilical cord occurs when the cord slips ahead of the presenting fetal part, potentially leading to cord compression and compromised fetal oxygenation. However, hypertonic contractions do not directly cause a prolapsed cord. Instead, factors such as premature rupture of membranes, abnormal fetal positioning, or excessive amniotic fluid (polyhydramnios) are more likely contributors to cord prolapse. Hypertonic contractions primarily affect uteroplacental circulation rather than fetal positioning.
Choice B reason:
One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it produces a prolapsed cord. This is incorrect because a prolapsed cord is not caused by hypertonic contractions, but by other factors such as a low-lying placenta, a premature rupture of membranes, a small or preterm fetus, or an abnormal presentation. A prolapsed cord occurs when the umbilical cord slips through the cervix and into the vagina before or during delivery. This can compress the cord and cut off the blood supply to the fetus, resulting in fetal bradycardia and possible death.
Choice C reason:
One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it increases maternal renal blood flow. This is incorrect because hypertonic contractions do not affect maternal renal blood flow directly. Maternal renal blood flow is influenced by factors such as maternal blood pressure, hydration, cardiac output, and renal function. Hypertonic contractions may cause maternal dehydration, which can reduce renal blood flow, but this is not a direct effect of oxytocin stimulation.
Choice D reason:
Hypertonic contractions reduce placental blood flow by limiting the relaxation phase between contractions. Normally, uterine contractions intermittently compress the spiral arteries supplying the placenta, but prolonged or excessively frequent contractions prevent adequate placental perfusion. This can lead to fetal hypoxia, acidosis, and distress, making it the most detrimental effect of oxytocin-induced hypertonic contractions.

Correct Answer is B
Explanation
Choice A reason:
Inspecting if the urethral opening appears circular. This is a correct action for the nurse to do, as it helps to identify any abnormalities in the urethral opening, such as hypospadias or epispadias, which are congenital defects where the opening is located on the underside or the top of the penis, respectively. • Choice B reason:
Retracting the foreskin over the glans to assess for secretions. This is an incorrect action for the nurse to avoid, as it can cause pain, bleeding, and infection in the newborn. The foreskin is usually adhered to the glans in newborns and should not be forcibly retracted. It will gradually loosen over time and can be retracted by the child himself when he is older. •
Choice C reason:
Palpating if testes are descended into the scrotal sac. This is a correct action for the nurse to do, as it helps to detect any undescended testes, which are more common in preterm infants and can increase the risk of infertility and testicular cancer later in life. • Choice D reason:
Inspecting the genital area for irritated skin. This is a correct action for the nurse to do, as it helps to identify any signs of diaper rash, fungal infection, or allergic reaction in the newborn's skin.
Correct Answer is A
Explanation
The correct answer is choice A, delayed respiratory depression.
Choice A reason:
Delayed respiratory depression is not one of the main nursing observations for a woman who receives epidural or intrathecal opioids. Epidural and intrathecal opioids are administered for pain relief during labor or after certain surgeries, and they act locally within the spinal cord to block pain signals. Unlike systemic opioids, which can cause respiratory depression when given in high doses, epidural and intrathecal opioids have a more limited systemic effect, reducing the risk of respiratory depression. Therefore, monitoring for delayed respiratory depression is not a primary concern in this context.
Choice B reason:
Choice B is a valid nursing observation for a woman who receives epidural or intrathecal opioids. These opioids can cause temporary paralysis or weakness in the lower extremities as a side effect of their action on the nerves in the spinal cord. Nurses need to assess the woman's ability to move her lower extremities and ensure her safety and comfort while this effect is present.
Choice C reason:
Choice C is a valid nursing observation for a woman who receives epidural or intrathecal opioids. Pruritus, which refers to itching or a sensation of itchiness, is a common side effect of opioids, including those administered via epidural or intrathecal routes. The nurse should assess the woman for any signs of pruritus and manage it appropriately if it occurs.
Choice D reason:
Choice D is a valid nursing observation for a woman who receives epidural or intrathecal opioids. Nausea and vomiting are common side effects of opioids, and they can occur after receiving these medications via epidural or intrathecal routes. The nurse should monitor the woman for any signs of nausea and vomiting and provide supportive care if needed.
