A nurse is preparing to administer clindamycin 900 mg by intermittent IV bolus over 30 min. Available is clindamycin 900 mg in 100 mL dextrose 5% (D5W). The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["200"]
The correct answer is 200 mL/hr.
To calculate the IV rate, the nurse should use the following formula:
IV rate (mL/hr) = (Volume to be infused (mL) / Time of infusion (hr)) x Drop factor (gtt/mL)
In this case, the volume to be infused is 100 mL, the time of infusion is 0.5 hr (30 min), and the drop factor is 1 gtt/mL (assuming the IV pump is calibrated in mL/hr). Therefore, the formula becomes:
IV rate (mL/hr) = (100 mL / 0.5 hr) x 1 gtt/mL
IV rate (mL/hr) = 200 mL/hr
The nurse should round the answer to the nearest whole number, which is 200 mL/hr. The nurse should use a leading zero if the answer is less than 1, which is not the case here. The nurse should not use a trailing zero, which means 200 mL/hr and not 200.0 mL/hr.

Correct Answer is C
Explanation
Choice A reason: Hypoglycemia is a low blood sugar level that can affect newborns, especially those who are premature, small for gestational age, or have diabetic mothers. However, hypoglycemia does not explain the high FHR, the low Apgar scores, or the pale and tachypneic appearance of the newborn.
Choice B reason: Phrenic nerve injury is a rare complication of cesarean section that can cause diaphragmatic paralysis and respiratory distress in the newborn. However, phrenic nerve injury usually affects only one side of the chest, and does not cause high FHR, low Apgar scores, or pallor.
Choice C reason: Sepsis is a serious infection that can affect newborns, especially those who are exposed to prolonged rupture of membranes, as in this case. Sepsis can cause high FHR, low Apgar scores, pale and tachypneic appearance, and other signs of shock and organ failure.
Choice D reason: Meconium aspiration syndrome is a condition where the newborn inhales meconium-stained amniotic fluid into the lungs, causing respiratory distress. However, meconium aspiration syndrome usually occurs in term or post-term infants, and is associated with low FHR, not high FHR. Meconium aspiration syndrome also causes cyanosis, not pallor.
Correct Answer is A
Explanation
Choice A reason: This statement is correct, as these are the common complications of post-term infants, who are born after 42 weeks of gestation. Meconium aspiration can occur when the fetus passes meconium in utero and inhales it into the lungs, causing respiratory distress, inflammation, and infection. Hypoglycemia can occur due to the depletion of glycogen stores and the increased metabolic demands. Dry, cracked skin can occur due to the loss of vernix caseosa and the reduced amniotic fluid.
Choice B reason: This statement is incorrect, as these are the signs of neonatal hypocalcemia, which is a low level of calcium in the blood. Neonatal hypocalcemia can occur due to maternal diabetes, prematurity, or asphyxia, and can cause jitteriness, seizures, or tetany.
Choice C reason: This statement is incorrect, as these are the characteristics of preterm infants, who are born before 37 weeks of gestation. Excessive vernix caseosa covering the skin is a protective coating that prevents heat and water loss. Lethargy and RDS are signs of immaturity and underdevelopment of the central nervous system and the lungs.
Choice D reason: This statement is incorrect, as these are the features of infants with erythroblastosis fetalis, which is a hemolytic disease caused by the incompatibility of the Rh factor or the ABO blood group between the mother and the fetus. Golden yellow to green-stained skin and nails are due to the accumulation of bilirubin, which is a breakdown product of red blood cells. Absence of scalp hair and an increased amount of subcutaneous fat are due to the chronic hypoxia and edema.
