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. Excessive lanugo:
This is incorrect. Excessive lanugo is more commonly seen in preterm newborns. Post-term newborns, such as those born at 43 weeks of gestation, typically have little to no lanugo due to its shedding during late gestation.

B. Hypotonia:
This is incorrect. Hypotonia (reduced muscle tone) is not a characteristic finding in post-term newborns. Post-term infants generally exhibit normal or increased muscle tone, unless there is an underlying condition or birth complication.

C. Absent vernix:
This is correct. Vernix caseosa, a protective substance that coats the skin in utero, is typically absent or minimal in post-term newborns because it is reabsorbed in the amniotic fluid as gestation progresses beyond term.

D. Dry, cracked skin:
This is correct. Post-term newborns often have dry, peeling, or cracked skin due to prolonged exposure to amniotic fluid. The lack of vernix exacerbates this condition, leading to skin that appears weathered or desquamated.

E. Long, hard nails:
This is correct. Post-term newborns frequently have long, hard nails that may extend beyond the fingertips. This is a result of extended fetal development time in utero

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.
