Answer and Explanation

The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"C"},"C":{"answers":"C"},"D":{"answers":"A"},"E":{"answers":"C"},"F":{"answers":"C"}}

1st Trimester (Conception-13 weeks)

Fetus has a heartbeat: The fetal heartbeat can typically be detected around 6 weeks gestation using ultrasound, marking the beginning of cardiac development in the first trimester.

2nd Trimester (14-26 weeks)

Gender can be determined: Gender determination through ultrasound is generally possible around the 18-20 week mark in the second trimester when fetal genitalia are more distinguishable.

3rd Trimester (27-40 weeks)

Surfactant production: Surfactant production by the fetal lungs begins in the third trimester, usually around 24-28 weeks, but continues to increase throughout the remainder of pregnancy.
Sucking occurs: Fetal sucking movements start to develop around the 28th week and become more coordinated as the third trimester progresses.
Fetal respiratory movements begin: Fetal respiratory movements, where the fetus practices breathing by moving the diaphragm, begin in the third trimester to prepare for life outside the womb.
Increase in body fat: The fetus begins to accumulate more body fat in the third trimester, which helps with thermoregulation and provides energy reserves for birth and early postnatal life.

Correct Answer is ["B","C","E"]

Explanation

A. Chronic fatigue. While chronic fatigue can occur in muscular dystrophy due to muscle weakness, it is not a direct side effect of corticosteroids.
B. Weight gain: Corticosteroids commonly cause weight gain due to increased appetite and fluid retention.
C. Mood changes: Mood swings and changes in behaviour are well-documented side effects of corticosteroid use.
D. Weight loss. Corticosteroids typically cause weight gain rather than weight loss.
E. Osteoporosis: Long-term use of corticosteroids can lead to decreased bone density and osteoporosis, making bone fractures more likely.

A. Keep eye shields on at all times, including when feeding B. Routinely monitor temperature while infant is in the crib C. Tightly swaddle the infant in blanket D. Expose as much of the infant's skin to the lights as possible

Correct Answer is D

Explanation

A. Keep eye shields on at all times, including when feeding. Incorrect because while eye protection is crucial under the lights, they can be removed during feedings to allow for parent-infant bonding and eye contact.
B. Routinely monitor temperature while the infant is in the crib. Incorrect, because temperature should be closely monitored while the infant is under phototherapy due to potential changes in body temperature caused by the exposure.
C. Tightly swaddle the infant in a blanket. Incorrect, as this would reduce the amount of skin exposed to the phototherapy lights and decrease the treatment's effectiveness.
D. Expose as much of the infant's skin to the lights as possible. Phototherapy is most effective when as much skin as possible is exposed to the lights because it allows for maximum light absorption and more effective bilirubin breakdown.
