Preterm infants are at greatest risk for.
perinatal mortality.
asphyxia.
cardiovascular complications.
prematurity-related complications.
The Correct Answer is D
Rationale:
A. While perinatal mortality is higher in preterm infants compared with term infants, it is a consequence rather than a direct risk factor.
B. Asphyxia can occur in both term and preterm infants and is not specific to prematurity.
C. Cardiovascular complications may arise but are only one aspect of the broader risks associated with prematurity.
D. Prematurity-related complications encompass the full spectrum of health risks preterm infants face, including respiratory distress syndrome, intraventricular hemorrhage, thermoregulation difficulties, feeding intolerance, and infection susceptibility. These complications are directly related to the immaturity of organ systems in infants born before 37 weeks’ gestation, making them the most comprehensive risk category.

C. Uvulitis can be examined carefully; it is not an absolute contraindication.
D. Bacterial tracheitis affects the lower airway and does not specifically contraindicate pharyngeal examination, though caution is advised if airway compromise is present.
Correct Answer is B
Explanation
Rationale:
A. A 25% chance of having the sickle cell trait occurs when both parents are carriers (heterozygous), not when they are unaffected.
B. If both parents are carriers (sickle cell trait, AS), each pregnancy carries a 25% chance that the child will inherit sickle cell disease (homozygous SS).
C. Each child also has a 25% chance of inheriting two normal alleles (AA) and being unaffected, but this does not equal 50%.
D. A 50% chance of having sickle cell anemia is incorrect; the risk is 25% per pregnancy for two carrier parents.
