A nurse is consulting a pharmacological reference about medication compatibility prior to administering warfarin to a client.
Which of the following medications should the nurse identify as being incompatible with warfarin?

Choice A rationale:

Administering 2 ounces of water to the newborn prior to the test is not a standard practice for newborn genetic screening. Newborns are typically screened for genetic disorders through a blood test, not by giving them water.

Choice B rationale:

This statement is incorrect. Newborn genetic screening is usually performed shortly after birth, not at 2 months old. Early screening allows for the early detection of certain genetic disorders, enabling timely interventions if needed.

Choice D rationale:

Drawing blood from the newborn's inner elbow is not specific guidance related to newborn genetic screening. Blood can be drawn from various sites, and healthcare providers choose the most appropriate site based on the newborn's condition and the required tests.

Explanation: Yellow patches in the mouth are an indication of oral candidiasis, also known as thrush, which is a fungal infection caused by Candida albicans. Oral candidiasis can cause symptoms such as pain, burning, redness, and difficulty swallowing in addition to yellow patches on the tongue, palate, cheeks, or throat. Hearing loss, night sweats, and

brittle nails are not manifestations of candida infection.
