A nurse is administering a miconazole vaginal suppository to a client who has vaginal candidiasis. Which of the following actions should the nurse take?

A: Administering the medication into the deltoid muscle is not recommended for newborns due to their underdeveloped muscle mass and the potential for injury. The vastus lateralis muscle in the thigh is the preferred site for intramuscular injections in infants.

B: Checking the mother's Rh factor is not directly related to the administration of phytonadione, which is given to prevent vitamin K deficiency bleeding in the newborn, a condition unrelated to the mother's Rh factor.

C: Administering the medication 12 hours after birth is not the standard practice. Phytonadione is typically given within the first hour after birth to ensure prompt prevention of hemorrhagic disease of the newborn.

D: Administering the medication with a 25 gauge needle is appropriate as it is small enough to cause minimal discomfort and large enough to ensure proper delivery of the medication into the infant's muscle tissue.

A: This infection does not directly cause hearing loss at birth. Hearing loss in newborns can be associated with genetic factors, birth complications, and certain infections, but GBS is not known to be a direct cause of hearing impairment.

B: A positive GBS test result does not necessitate a cesarean birth. The standard management for GBS-positive mothers is the administration of intrapartum antibiotic prophylaxis, not cesarean delivery, unless there are other obstetric indications.

C: Testing for GBS is typically done between 36 and 37 weeks of gestation because this timing is close to delivery, when the test results are most predictive of the baby's risk of exposure during birth.

D: Antibiotics are not given during the last 2 weeks of pregnancy to prevent GBS transmission. Instead, they are administered during labor to ensure effective levels of the drug during delivery, which is the critical period for preventing transmission to the baby.
