Half an ounce.
Three.
Two.
One.
None
None
The Correct Answer is D
Choice A rationale:
One ounce is equivalent to 29.57 ml (30 mls when rounded off to the nearest whole number). This conversion is essential in pediatric care, especially when administering medications to infants, as doses are often prescribed in milliliters.
Choice B rationale:
One ounce is equivalent to 29.57 ml (30 mls when rounded off to the nearest whole number). This conversion is essential in pediatric care, especially when administering medications to infants, as doses are often prescribed in milliliters.
Choice C rationale:
One ounce is equivalent to 29.57 ml (30 mls when rounded off to the nearest whole number). This conversion is essential in pediatric care, especially when administering medications to infants, as doses are often prescribed in milliliters.

Correct Answer is B
Explanation
Choice A rationale:
Providing a heat source for the newborn is not the purpose of surfactant. Surfactant is a substance produced in the lungs to reduce surface tension and prevent alveolar collapse during expiration. It helps with the exchange of gases, but it does not generate heat.
Choice B rationale:
This is the correct answer. Surfactant plays a crucial role in assisting the alveoli to remain open by reducing surface tension. This, in turn, allows for proper gas exchange, especially of oxygen and carbon dioxide.
Choice C rationale:
Assisting the ductus arteriosus to remain open is not the purpose of surfactant. The ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs. After birth, it should close on its own, and surfactant does not influence this process.
Choice D rationale:
Providing energy to the newborn is not the purpose of surfactant. Energy for the newborn comes from nutrition, particularly breast milk or formula, and not from surfactant
Correct Answer is C
Explanation
Choice A rationale:
The liver's job related to bilirubin is not changing conjugated bilirubin to unconjugated. Conjugated bilirubin is the water-soluble form of bilirubin that is excreted in bile and urine. Unconjugated bilirubin, on the other hand, is the fat-soluble form, which is transported to the liver and conjugated to become water-soluble. The conversion goes from unconjugated to conjugated, not the other way around.
Choice B rationale:
The liver's job related to bilirubin is not the synthesis of vitamin K. The liver is responsible for synthesizing clotting factors, including factors II (prothrombin), VII, IX, and X, but not vitamin K itself. Vitamin K is obtained from dietary sources or supplements and is essential for blood clotting.
Choice C rationale:
This choice is the correct answer. The liver's primary function related to bilirubin is changing unconjugated bilirubin to conjugated bilirubin. As mentioned earlier, unconjugated bilirubin is produced from the breakdown of heme in old red blood cells, and it needs to be processed in the liver to become water-soluble and eventually excreted in bile and urine.
Choice D rationale:
The liver's job related to bilirubin does not involve the removal of meconium. Meconium is the first stool passed by a newborn, and its elimination is unrelated to the liver's function in processing bilirubin.
