NurseDive Free Nursing Practice Question
A nurse is administering a unit of RBC 350 mL over 3 hr to a client who has anemia. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number)
This question is an excerpt from Nurse Dive's nursing test bank - ATI Maternal Newborn Proctored Exam 4. Take the full exam now
Full Explanation
The correct answer is 117 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 350 mL, the time of infusion is 3 hr, 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) = (350 mL / 3 hr) x 1 gtt/mL
IV rate (mL/hr) = 116.67 mL/hr
The nurse should round the answer to the nearest whole number, which is 117 mL/hr.

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)
Full Explanation
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.
A nurse is preparing to administer atenolol 50 mg PO daily to a client. The amount available is atenolol 100 mg/tablet. How many tablets should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
Full Explanation
To calculate the number of tablets, the nurse should use the following formula:
Number of tablets = (Desired dose / Available dose) x (Available form / Desired form)
In this case, the desired dose is 50 mg, the available dose is 100 mg, the available form is 1 tablet, and the desired form is 1 tablet. Therefore, the formula becomes:
Number of tablets = (50 mg / 100 mg) x (1 tablet / 1 tablet)
Number of tablets = 0.5 x 1
Number of tablets = 0.5
The nurse should round the answer to the nearest tenth, which is 0.5. The nurse should use a leading zero if the answer is less than 1, which is 0.5. The nurse should not use a trailing zero, which means 0.5 and not 0.50.
A client comes to the emergency room reporting severe abdominal cramping and heavy bleeding at 10 weeks gestation. Cervical examination reveals heavy bleeding, the cervical os is open and tissue is present. Which type of abortion is the client experiencing?
A. Missed miscarriage
Missed miscarriage is not the type of abortion that the client is experiencing, because it is characterized by the absence of fetal heart activity and the retention of the products of conception in the uterus. The client would not have heavy bleeding or tissue expulsion.
B. Incomplete miscarriage
Incomplete miscarriage is the type of abortion that the client is experiencing, because it is characterized by the partial expulsion of the products of conception from the uterus, with some tissue remaining inside. The client would have heavy bleeding, open cervical os, and tissue present.
C. Inevitable miscarriage
Inevitable miscarriage is not the type of abortion that the client is experiencing, because it is characterized by the rupture of membranes and dilation of the cervical os, but no expulsion of the products of conception. The client would have moderate bleeding and cramping, but no tissue present.
D. Complete miscarriage
Complete miscarriage is not the type of abortion that the client is experiencing, because it is characterized by the complete expulsion of the products of conception from the uterus. The client would have mild bleeding and cramping, and a closed cervical os.
Full Explanation
Choice A reason: Missed miscarriage is not the type of abortion that the client is experiencing, because it is characterized by the absence of fetal heart activity and the retention of the products of conception in the uterus. The client would not have heavy bleeding or tissue expulsion.
Choice B reason: Incomplete miscarriage is the type of abortion that the client is experiencing, because it is characterized by the partial expulsion of the products of conception from the uterus, with some tissue remaining inside. The client would have heavy bleeding, open cervical os, and tissue present.
Choice C reason: Inevitable miscarriage is not the type of abortion that the client is experiencing, because it is characterized by the rupture of membranes and dilation of the cervical os, but no expulsion of the products of conception. The client would have moderate bleeding and cramping, but no tissue present.
Choice D reason: Complete miscarriage is not the type of abortion that the client is experiencing, because it is characterized by the complete expulsion of the products of conception from the uterus. The client would have mild bleeding and cramping, and a closed cervical os.
