A nurse is ordered to administer 750 mL of IV fluid over 6 hours.
The IV tubing has a drop factor of 20 drops per mL. How many drops per minute should the nurse set the IV flow rate to deliver the correct amount? Round to the nearest whole number.
Enter numeric value only.
The Correct Answer is ["42"]
Step 1 is: 750 mL ÷ 6 hours.
Step 2 is: 125 mL/hour.
Step 3 is: 6 hours × 60 minutes = 360 minutes.
Step 4 is: (750 mL ÷ 360 minutes) × 20 drops/mL.
Step 5 is: 2.0833333333333335 × 20.

Correct Answer is D
Explanation
Choice A rationale
Influenza, or the flu, can cause severe illness in pregnant women and is associated with a higher risk of complications such as pneumonia, preterm birth, and low birth weight. However, it is not typically known to cause the specific congenital malformations mentioned, such as microcephaly and severe neurological issues, in the same way as other infectious agents that can cross the placental barrier.
Choice B rationale
Gonorrhea is a sexually transmitted infection that can be passed to the newborn during delivery, causing neonatal conjunctivitis or blindness. While it can cause serious issues, it is not associated with the embryonic-phase congenital defects like microcephaly, as it typically affects the infant during or after birth, not during the embryonic stage of development.
Choice C rationale
COVID-19 infection during pregnancy can increase the risk of preterm birth, preeclampsia, and stillbirth. While there is ongoing research, it has not been definitively linked to causing the severe congenital defects, such as microcephaly, associated with infections like Cytomegalovirus. Its main impacts are generally related to placental function and respiratory illness in the mother.
Choice D rationale
Cytomegalovirus (CMV) is a common viral infection that, when contracted by a pregnant woman for the first time, can be transmitted to the fetus, particularly during the first trimester (embryonic phase). Congenital CMV is a leading cause of non-genetic neurological damage in newborns, including microcephaly, hearing loss, and intellectual disabilities, due to its teratogenic effects on the developing fetal brain. *.
