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: Placenta previa is a condition where the placenta covers the cervix partially or completely. It can cause painless vaginal bleeding, but not abdominal pain.
Choice B reason: Prolapsed cord is a condition where the umbilical cord slips through the cervix and protrudes into the vagina or beyond. It can cause fetal distress, but not abdominal pain or vaginal bleeding.
Choice C reason: Incompetent cervix is a condition where the cervix dilates prematurely and painlessly. It can cause preterm labor and delivery, but not abdominal pain or vaginal bleeding.
Choice D reason: Abruptio placentae is a condition where the placenta separates from the uterine wall before delivery. It can cause severe abdominal pain, vaginal bleeding, and fetal distress. It is a medical emergency that requires immediate intervention.
Correct Answer is B
Explanation
Choice A reason: Assisting the client with transferring to the gynecology unit is not the first action that the nurse should take, as it does not address the client's emotional needs or preferences. The nurse should first assess the client's coping and grieving process, and provide support and comfort.
Choice B reason: Offering the mother private time with the newborn is the first action that the nurse should take, as it can facilitate the bonding and closure process, and help the client express her feelings and emotions. The nurse should respect the client's wishes and cultural beliefs regarding the viewing and holding of the stillborn infant, and provide a quiet and private environment.
Choice C reason: Administering alprazolam 0.5 mg PO is not the first action that the nurse should take, as it is a pharmacological intervention that requires a prescription and an assessment of the client's condition and history. The nurse should first use nonpharmacological methods, such as active listening, therapeutic communication, and counseling, to help the client cope and manage her anxiety and grief.
Choice D reason: Contacting the health care facility's clergy is not the first action that the nurse should take, as it may not be appropriate or desired by the client. The nurse should first ask the client if she wants any spiritual or religious support, and respect her decision and beliefs.
