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 D
Explanation
Choice A reason: Calcium carbonate is not the compound that the nurse should have readily available, as it is an antacid that neutralizes stomach acid and relieves heartburn. Calcium carbonate is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.
Choice B reason: Potassium chloride is not the compound that the nurse should have readily available, as it is an electrolyte supplement that replenishes potassium levels and prevents hypokalemia. Potassium chloride is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.
Choice C reason: Ferrous sulfate is not the compound that the nurse should have readily available, as it is an iron supplement that prevents or treats iron deficiency anemia. Ferrous sulfate is not used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.
Choice D reason: Calcium gluconate is the compound that the nurse should have readily available, as it is an antidote that reverses the effects of magnesium sulfate and restores calcium levels and neuromuscular function. Calcium gluconate is used to treat severe preeclampsia or magnesium sulfate toxicity, which are the conditions that the client may have.
Correct Answer is D
Explanation
Choice A reason: Thrombophlebitis is a condition where a blood clot forms in a vein and causes inflammation and pain. The risk factors for thrombophlebitis include immobility, dehydration, obesity, smoking, and cesarean birth. This client is not at increased risk for thrombophlebitis based on the information given.
Choice B reason: Retained placental fragments are pieces of the placenta that remain in the uterus after delivery and can cause bleeding, infection, or uterine subinvolution. The risk factors for retained placental fragments include placenta previa, placenta accreta, manual removal of the placenta, and incomplete separation of the placenta. This client is not at increased risk for retained placental fragments based on the information given.
Choice C reason: Puerperal infection is an infection of the reproductive tract that occurs within six weeks after delivery and can cause fever, malaise, abdominal pain, and foul-smelling lochia. The risk factors for puerperal infection include prolonged rupture of membranes, prolonged labor, multiple vaginal examinations, operative delivery, and retained placental fragments. This client is not at increased risk for puerperal infection based on the information given.
Choice D reason: Uterine atony is a condition where the uterus fails to contract and retract after delivery and can cause excessive bleeding, hypovolemic shock, and hemorrhage. The risk factors for uterine atony include overdistension of the uterus, prolonged labor, oxytocin use, anesthesia, and trauma. This client is at increased risk for uterine atony due to the large size of the newborn, which can overstretch the uterus and impair its ability to contract.
