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 A
Explanation
Choice A reason: Erythroblastosis fetalis is the correct answer, as it is a hemolytic disease of the newborn that occurs when the mother is Rh-negative and the newborn is Rh-positive, and the maternal antibodies cross the placenta and destroy the newborn's red blood cells, causing anemia, jaundice, and edema. Rh0 (D) immunoglobulin is an injection that prevents the formation of Rh-positive antibodies in the mother, and reduces the risk of erythroblastosis fetalis in the current or subsequent pregnancies.
Choice B reason: Hypobilirubinemia is not the correct answer, as it is a low level of bilirubin in the blood that can cause pale skin, poor feeding, or lethargy. Hypobilirubinemia is not related to the Rh factor or the Rh0 (D) immunoglobulin injection, and it is not a common or serious complication in the newborn.
Choice C reason: Biliary atresia is not the correct answer, as it is a congenital defect of the bile ducts that prevents the flow of bile from the liver to the intestine, causing jaundice, dark urine, and clay-colored stools. Biliary atresia is not related to the Rh factor or the Rh0 (D) immunoglobulin injection, and it is not a preventable complication in the newborn.
Choice D reason: Transient clotting difficulties is not the correct answer, as it is a bleeding disorder that occurs due to the deficiency of vitamin K, which is essential for the synthesis of clotting factors. Transient clotting difficulties is not related to the Rh factor or the Rh0 (D) immunoglobulin injection, and it is preventable by administering vitamin K to the newborn.
Correct Answer is D
Explanation
A. Contractions lasting longer than 90 seconds: Prolonged contractions lasting longer than 90 seconds may indicate uterine hyperstimulation, which can compromise fetal oxygenation and lead to fetal distress. This finding should be reported to the provider promptly for further evaluation and management.
B. Client reports feeling contractions in the lower back: This is a common sensation during labor and may not necessarily indicate a complication. However, if associated with other signs of fetal distress, it should be reported.
C. Contractions occurring every 3 to 5 minutes: This frequency is within the normal range for the active phase of labor and does not necessarily indicate a problem. However, it is essential to consider the duration and intensity of contractions along with this frequency.
D. Contractions are strong in intensity: While strong contractions are typical during the active phase of labor, the intensity alone may not be a cause for concern unless they are associated with uterine hyperstimulation.
