A nurse is aware that which type of heat loss in newborns occurs through direct contact with a cooler surface?

Choice A rationale

Oral contraceptive pills, while effective when taken correctly, rely on user compliance and are not the most reliable if doses are missed.

Choice B rationale

Diaphragms with spermicide are less effective than IUDs and require proper placement before intercourse, making them more prone to user error.

Choice C rationale

Intrauterine devices (IUDs) are long-term, highly effective contraceptive methods with low failure rates, and they do not depend on daily user compliance.

Choice D rationale

Male condoms are effective but have a higher failure rate compared to IUDs due to potential breakage or improper use.

Choice A rationale

• Normal neonatal glucose: >45 mg/dL (ideally 50–110 mg/dL).

• A level of 40 is low → risk for hypoglycemia complications (seizures, brain injury).

While it is important to monitor glucose levels, a reading of 40 mg/dL is low and requires immediate attention. Waiting 4 hours could allow the newborn's condition to deteriorate further. Hypoglycemia in newborns can lead to serious complications if not treated promptly.

Choice B rationale

Assessing for hypothermia is essential, but it is not the first priority when a newborn has low blood glucose levels. Immediate steps should be taken to address the hypoglycemia to prevent further complications, as it is a more immediate threat to the newborn's health.

Choice C rationale

Notifying the physician on call is the correct priority intervention. A blood glucose level of 40 mg/dL is concerning, and prompt medical intervention is necessary. The physician can order appropriate treatment to stabilize the newborn's glucose levels and prevent potential complications.

Choice D rationale

Re-evaluating the blood serum glucose is important but comes after initiating immediate intervention. Continuous monitoring should follow initial treatment to ensure the newborn's glucose levels stabilize. Immediate action is crucial to address the hypoglycemia effectively.
