A nurse is caring for a newborn in the neonatal unit following delivery.
Complete the following sentence by using the list of options.
The nurse should further evaluate
The Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"C"}
The nurse should further evaluate respiratory characteristics and muscle tone to determine if the newborn is experiencing a complication.
Rationale for correct answers
Respiratory characteristics are critical to assess because irregular and shallow breathing in a newborn can indicate neurological or respiratory dysfunction. Normal neonatal respiratory rate ranges from 30 to 60 breaths per minute with regular pattern; deviations may signal distress or central nervous system issues. Muscle tone evaluation is essential since increased tone with tremors suggests possible neurologic irritability or withdrawal. Normal newborn muscle tone should be moderate, neither hypotonic nor hypertonic, with symmetrical movement. These signs correlate with the high-pitched cry, tremors, and exaggerated reflexes noted, which may indicate neurological complications such as withdrawal syndrome or hypoxic-ischemic encephalopathy.
Rationale for incorrect answers
Heart rate (A) is important but was not reported abnormal; normal neonatal heart rate ranges from 120 to 160 beats per minute and the absence of murmurs suggests no cardiac compromise. Temperature (C) is less urgent as mucous membranes are moist and skin warm and dry, indicating stable thermoregulation; normal newborn temperature is 36.5–37.5°C. Feeding patterns (D) appear adequate with no difficulty reported, making this less immediately concerning.
Rationale for incorrect answers
Moro reflex (A) and Babinski reflex (B) are both present and exaggerated, which may be reactive but less specific for immediate concern than muscle tone abnormalities. Skin color (D) is normal without cyanosis or jaundice, reducing the likelihood of hypoxia or hemolytic issues.
Take home points
- Respiratory pattern irregularities in newborns may indicate neurological or respiratory dysfunction.
- Abnormal muscle tone and tremors are key signs of potential neurological complications.
- Normal heart rate, temperature, feeding, and skin color reduce likelihood of cardiac or systemic illness.
- Reflex exaggeration alone is less specific than muscle tone and respiratory changes for early complication detection.

Correct Answer is B
Explanation
Choice A rationale
Immediately bathing a newborn with herpes simplex virus is generally discouraged. While it might seem intuitive for infection control, vigorous bathing could theoretically disrupt skin integrity and potentially spread the virus to other areas of the body or mucous membranes, exacerbating the infection.
Choice B rationale
Initiating contact precautions is essential for a newborn with herpes simplex virus. This highly contagious viral infection requires strict measures to prevent transmission to other vulnerable neonates and healthcare providers. Contact precautions involve gown and glove use, limiting direct contact with the newborn or contaminated surfaces.
Choice C rationale
Administering ampicillin IV is not the appropriate treatment for herpes simplex virus. Ampicillin is an antibiotic effective against bacterial infections, not viral infections like herpes simplex. Antiviral medications, such as acyclovir, are the specific treatment for neonatal herpes simplex virus to inhibit viral replication.
Choice D rationale
Withholding breastfeeding is not typically indicated for a newborn with in utero transmitted herpes simplex virus unless the mother has active lesions on her breasts. The primary concern is direct skin-to-skin transmission if lesions are present. Breast milk itself provides beneficial antibodies and is not a route of transmission for in utero infection.
Correct Answer is B
Explanation
Choice A rationale
A temperature of 37.7° C (99.9° F) in the immediate postpartum period is a relatively common and often benign finding, typically within normal limits or indicating mild dehydration or exertion from labor. A slight elevation is not usually a cause for immediate concern unless accompanied by other signs of infection, which would warrant further investigation. Normal range is 36.5° C to 37.5° C (97.7° F to 99.5° F).
Choice B rationale
A boggy fundus is a significant finding that the nurse should report immediately. A boggy, soft uterus indicates uterine atony, which means the uterine muscles are not contracting effectively. This significantly increases the risk of postpartum hemorrhage due to inadequate compression of uterine blood vessels.
Choice C rationale
Lochia rubra with small clots is considered a normal finding in the immediate postpartum period. Lochia rubra is the initial dark red discharge consisting of blood, decidual tissue, and mucus. Small clots are expected as blood clots and detaches from the uterine wall, reflecting normal uterine involution.
Choice D rationale
Minimal perineal edema is a normal and expected finding after vaginal delivery. The trauma of childbirth often results in some degree of swelling in the perineal area. "Minimal" edema indicates that the swelling is not excessive and does not suggest a complication requiring immediate reporting to the provider.
