Correct Answer is C
Explanation
A. Gingivitis is common during pregnancy and should be addressed but is not as urgent as dysuria.
B. Varicose veins, while uncomfortable, are not an immediate priority.
C. Dysuria (painful or difficult urination) can be a sign of a urinary tract infection, which is a concern during pregnancy. Prompt reporting and treatment are essential to prevent
complications.
D. Leukorrhea (an increase in vaginal discharge) is common in pregnancy and is not a cause for immediate concern.
Correct Answer is ["C","D","E"]
Explanation
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
