Which of the following is most indicative of postpartum subinvolution?

A.

Uterine atony.

B.

Prolonged lochia discharge.

C.

Severe cramping.

D.

High fever.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Uterine atony refers to a lack of muscle tone in the uterus, leading to postpartum hemorrhage, not subinvolution.

Choice B rationale

Prolonged lochia discharge indicates incomplete uterine involution, as the uterus has not returned to its pre-pregnancy size.

Choice C rationale

Severe cramping may be related to other postpartum complications and is not specific to subinvolution.

Choice D rationale

High fever is more indicative of an infection rather than subinvolution of the uterus.

Explanation

  1. Jittery Extremities
    • Hypoglycemia: Jittery extremities are a common sign of low blood glucose levels.
    • Neonatal Abstinence Syndrome: Jitteriness can occur due to withdrawal symptoms in newborns exposed to opioids.
  2. Poor Sucking Reflex
    • Hypoglycemia: Newborns with low blood glucose levels may have difficulty feeding and a poor sucking reflex.
    • Neonatal Abstinence Syndrome: Poor feeding and sucking reflex can be part of withdrawal symptoms in newborns.
  3. Excessive Sweating
    • Hypoglycemia: Excessive sweating can be a symptom of low blood glucose levels.
    • Neonatal Abstinence Syndrome: Sweating is one of the possible signs of withdrawal in newborns.
  4. Irritability
    • Hypoglycemia: Irritability can result from low blood glucose levels.
    • Neonatal Abstinence Syndrome: Irritability is a common symptom of withdrawal in newborns exposed to opioids.
  5. Weak Cry
    • Hypoglycemia: A weak cry can be a symptom of low blood glucose levels.
    • Neonatal Abstinence Syndrome: Weak cry can also be part of withdrawal symptoms in newborns.
  6. Mild Tremors
    • Hypoglycemia: Tremors or shaking can be a sign of low blood glucose levels.
    • Neonatal Abstinence Syndrome: Tremors are common withdrawal symptoms in newborns exposed to opioids.
  7. Low Blood Glucose Level
    • Hypoglycemia: A blood glucose level of 40 mg/dL is considered low and indicates hypoglycemia.
    • Neonatal Abstinence Syndrome: Low blood glucose level is not a direct indicator of NAS but may occur due to poor feeding.
  8. Positive Urine Toxicology
    • Hypoglycemia: Not relevant.
    • Neonatal Abstinence Syndrome: Positive urine toxicology for opioids indicates in utero exposure to opioids, which can lead to NAS.

Correct Answer is B

Explanation

Choice A rationale

Blood glucose level changes are unrelated to hyperbilirubinemia and phototherapy, which specifically target bilirubin metabolism in the newborn's liver and skin.

Choice B rationale

A decrease in transcutaneous bilirubin (TcB) levels shows effective phototherapy, as it converts bilirubin into water-soluble isomers that can be excreted.

Choice C rationale

Skin color changes from yellow to normal indicate reduced bilirubin levels, but the most accurate measure of phototherapy efficacy is the decrease in TcB levels.

Choice D rationale

Weight gain is not an indicator of effective phototherapy; it reflects overall nutrition and hydration status rather than bilirubin metabolism and excretion.
