Which statement describes a disadvantage of phenolics in healthcare disinfection?

• A. They can bleach fabrics.
• B. They are contraindicated in bladder cancer patients.
• C. They have a limited shelf life once prepared.
• D. They are contraindicated in newborn nurseries.

Answer: (D)

Phenolics offer strong disinfection but come with notable safety concerns for vulnerable patients. Newborns have very delicate skin and immature metabolism, so exposure to phenolic compounds can irritate or be absorbed through the skin and lungs, posing toxicity risks. Residual phenolics on surfaces or in the air around incubators and newborn care areas can increase that exposure, making these disinfectants unsuitable in nurseries. That safety profile is why using phenolics in newborn nurseries is contraindicated. Other statements don’t capture the main clinical risk: while some cleaners may stain fabrics or have shelf-life considerations, those are not the central reason phenolics are avoided in nurseries. The concept centers on protecting neonates from chemical exposure, so avoiding phenolics in newborn care settings is the most appropriate precaution.
