A nurse is preparing to collect a specimen for newborn screening.
Which of the following actions should the nurse take?

Choice A rationale

Tetracycline is contraindicated in pregnancy due to its potential to cause fetal harm, including teeth discoloration and inhibition of bone growth.

Choice B rationale

Acyclovir is an antiviral medication used to treat herpes infections, not chlamydia.

Choice C rationale

Metronidazole is used to treat bacterial vaginosis and trichomoniasis, not chlamydia.

Choice D rationale

Amoxicillin is a safe and effective antibiotic for treating chlamydia in pregnant women. It is preferred due to its safety profile and effectiveness.

Choice A rationale

Applying lotion to the newborn’s extremities every 8 hours is not recommended during phototherapy. Lotions and ointments can cause burns when exposed to phototherapy lights and may interfere with the treatment’s effectiveness.

Choice B rationale

Repositioning the newborn every 4 hours is not frequent enough. The newborn should be repositioned every 2 hours to ensure even exposure to the phototherapy light and to prevent pressure sores.

Choice C rationale

Removing the eye mask during feedings is correct. The eye mask should be removed during feedings to allow for bonding and to check for any signs of irritation or infection. This also ensures that the newborn’s eyes are protected from the phototherapy light when not under the lamp.

Choice D rationale

Supplementing feedings with glucose water is not recommended. Breast milk or formula should be used to ensure the newborn receives adequate nutrition and hydration. Glucose water does not provide the necessary nutrients and can interfere with breastfeeding.
