A nurse is reviewing the laboratory results of a newborn who is 24 hr old. Which of the following findings should the nurse report to the provider?
Hemoglobin 12 g/dL.
Glucose 50 mg/dL.
Bilirubin 4 mg/dL.
Platelets 200,000/mm³.
The Correct Answer is A
The correct answer is: A. Hemoglobin 12 g/dL.
Choice A reason:
Hemoglobin levels in newborns are expected to be significantly higher than in adults due to the physiological adaptation to life outside the womb. The normal range for a newborn’s hemoglobin is approximately 14 to 24 g/dL1234. A level of 12 g/dL is below the expected range and could indicate anemia or other underlying conditions that may require further investigation and intervention by the healthcare provider.
Choice B reason:
The glucose level in a newborn can vary, especially within the first few hours after birth. Normal blood glucose levels for a newborn 1 to 2 hours old can be as low as 25 mg/dL and can rise to adult levels (60-100 mg/dL) within the first few days5. A glucose level of 50 mg/dL in a 24-hour-old newborn falls within the acceptable range and would not typically require reporting to the provider unless accompanied by symptoms of hypoglycemia.
Choice C reason:
Bilirubin levels in newborns can be elevated due to the normal breakdown of fetal hemoglobin as the baby’s liver matures. Normal bilirubin levels for a newborn can range from 1.0 to 12.0 mg/dL6. A bilirubin level of 4 mg/dL is within the normal range for a 24-hour-old newborn and is not typically a cause for concern unless there are signs of jaundice or other symptoms.
Choice D reason:
The normal platelet count for a newborn ranges from 150,000 to 450,000/mm³7. A platelet count of 200,000/mm³ is well within the normal range for a newborn and would not need to be reported to the healthcare provider.

Correct Answer is A
Explanation
Choice A rationale:
Petroleum jelly is a common recommendation to apply during diaper changes for circumcised newborns. It acts as a barrier between the diaper and the healing penis, reducing friction and preventing the diaper from sticking to the sensitive area. This can help promote better healing and prevent discomfort for the newborn.
Choice B rationale:
Pre-moistened towelettes are not typically recommended for application on the penis of a circumcised newborn during diaper changes. These towelettes may contain chemicals or irritants that could potentially irritate the delicate skin of the healing area.
Choice C rationale:
Povidone-iodine is an antiseptic solution often used to disinfect the skin before procedures or surgeries. However, it is not recommended for routine use on the penis of a circumcised newborn during diaper changes as it may be too harsh for the healing skin.
Choice D rationale:
Silver sulfadiazine is a topical antimicrobial agent used for treating burns and certain infections. However, it is not indicated for use on a circumcised newborn's penis during diaper changes. The healing process after circumcision does not usually involve infections that require this type of treatment.
Correct Answer is C
Explanation
Choice A rationale:
Tamoxifen is not used to treat Non-Hodgkin's lymphoma. Tamoxifen is a selective estrogen
receptor modulator (SERM) and is primarily used in breast cancer treatment. It functions by
binding to estrogen receptors, blocking estrogen's effects, and inhibiting the growth of
hormone-sensitive breast cancer cells.
Choice B rationale:
Tamoxifen is not used to treat endometriosis. Endometriosis is a condition in which tissue
similar to the lining of the uterus grows outside the uterus, and it is typically managed with
hormonal therapies, pain medications, or surgical interventions, but not tamoxifen.
Choice C rationale:
This is the correct choice. Tamoxifen is widely used in the treatment of breast cancer,
especially in cases of estrogen receptor-positive breast cancer. It helps prevent cancer
recurrence and is often prescribed for both early-stage and advanced breast cancer patients.
Choice D rationale:
Tamoxifen is not used to treat polycystic ovary syndrome (PCOS). PCOS is a hormonal
disorder characterized by enlarged ovaries with small cysts, and it is typically managed with
lifestyle changes, hormonal contraceptives, and medications to regulate menstrual cycles and
manage symptoms like hirsutism and acne.
