The Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
Heel warming increases capillary blood flow, improving sample accuracy and reducing hemolysis risk. Capillary glucose testing requires adequate perfusion for reliable results. Breastfeeding provides immediate glucose substrate to correct mild hypoglycemia. Normal neonatal blood glucose is >40–45 mg/dL; this newborn’s initial level of 35 mg/dL is below threshold, but responsive to feeding. Breast milk contains lactose, metabolized to glucose and galactose, supporting cerebral energy demands.
Rationale for incorrect Response 1 options: Administer glucose gel is appropriate only if feeding fails or glucose remains <25 mg/dL in asymptomatic or <40 mg/dL in symptomatic neonates. This newborn improved with feeding. Start IV fluids is reserved for persistent hypoglycemia or symptomatic neonates unresponsive to oral intake. The newborn stabilized post-breastfeeding. Phototherapy treats hyperbilirubinemia, not hypoglycemia. No bilirubin levels or jaundice signs were reported.
Rationale for incorrect Response 2 options: Supplement with formula is secondary to breastfeeding unless maternal milk is unavailable or ineffective. Breastfeeding was successful post-latch correction. Administer insulin is contraindicated; insulin lowers glucose and is used only in hyperglycemia. Monitor for jaundice is unrelated to hypoglycemia management unless bilirubin levels are elevated. No clinical jaundice was noted.
Take-home points:
- Neonatal hypoglycemia is defined as glucose <40–45 mg/dL; early feeding is first-line intervention.
- Macrosomic infants (birth weight >4,000 g) are at risk due to hyperinsulinemia post-placental glucose withdrawal.
- Differentiate hypoglycemia from sepsis, hypothermia, and metabolic disorders—all may present with jitteriness and hypotonia.
- Capillary sampling requires heel warming to ensure perfusion and accurate glucose measurement.

Correct Answer is A
Explanation
Choice A rationale
Nalbuphine hydrochloride is a synthetic opioid agonist-antagonist analgesic often used for pain relief during labor. Its agonist effects on kappa (κ) opioid receptors in the central nervous system lead to analgesia and common side effects, including central nervous system depression. Sedation is a frequent manifestation of this effect, caused by the drug's action on brain centers controlling arousal.
Choice B rationale
Nalbuphine primarily acts as an opioid, and its μ-receptor antagonist activity counteracts some opioid effects, but typical opioid-related gastrointestinal effects include decreased peristalsis, often leading to constipation. Diarrhea is not a common or expected adverse effect of nalbuphine; instead, it tends to slow gut motility due to its opioid effects on the enteric nervous system.
Choice C rationale
Opioid use, including nalbuphine, can sometimes lead to the adverse effect of urinary retention, due to increased detrusor muscle tone and internal sphincter spasm, which is a suppression of the micturition reflex. Diuresis, which is an increased or excessive production of urine, is not a recognized adverse effect of this medication.
Choice D rationale
Opioids, such as nalbuphine, typically interact with the thermoregulatory centers in the hypothalamus, often resulting in hypothermia due to vasodilation and decreased metabolic rate, not fever. Fever (pyrexia) is not a common or characteristic adverse effect associated with the administration of nalbuphine hydrochloride during labor.
Correct Answer is A
Explanation
Choice A rationale
Transcutaneous electrical nerve stimulation (TENS) operates on the Gate Control Theory of Pain, where non-painful electrical stimuli are applied, attempting to block the transmission of pain signals. The intensity must be manually increased by the client during a contraction to override the escalating pain impulse and achieve maximum analgesic effect when the pain is most intense, providing the best pain modulation.
Choice B rationale
TENS is primarily used for the low back pain and abdominal pain experienced during the active phase of the first stage of labor (cervical dilation), providing a distraction and non-pharmacological pain relief option. It is less effective during the second stage (pushing) and is not typically indicated for the third stage of labor (placental expulsion), which has different pain mechanisms.
Choice C rationale
TENS works by stimulating large sensory nerve fibers to modulate or decrease the perception of pain (pain modulation), offering a sense of control and relief, but it does not eliminate the pain entirely, particularly the intense visceral pain of uterine contractions. It is a non-invasive pain coping mechanism, not an anesthetic agent that would abolish pain sensation.
Choice D rationale
Gestational diabetes mellitus (GDM) is a maternal metabolic condition and is not a contraindication for the use of TENS during labor. The primary contraindications for TENS include the use of a cardiac pacemaker, application over the heart or head, or in the presence of fetal electronic monitoring electrodes that could conduct the current, none of which are related to GDM.
