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)

Answer and Explanation

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: Preeclampsia is not the correct answer, as it is a hypertensive disorder of pregnancy that causes high blood pressure, proteinuria, and edema. Preeclampsia can be a risk factor for abruptio placentae, which is a premature separation of the placenta from the uterine wall, but it is not a complication of it. Preeclampsia does not cause petechiae or bleeding around the IV access site, but rather headaches, blurred vision, or epigastric pain.

Choice B reason: Anaphylactoid syndrome of pregnancy is not the correct answer, as it is a rare and fatal condition that occurs when the amniotic fluid enters the maternal circulation and causes an allergic reaction. Anaphylactoid syndrome of pregnancy can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Anaphylactoid syndrome of pregnancy would cause respiratory distress, hypotension, or cardiac arrest.

Choice C reason: Puerperal infection is not the correct answer, as it is a bacterial infection of the reproductive tract that occurs after childbirth. Puerperal infection can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Puerperal infection would cause fever, foul-smelling lochia, or pelvic pain.

Choice D reason: Disseminated intravascular coagulation is the correct answer, as it is a coagulation disorder that causes widespread clotting and bleeding in the body. Disseminated intravascular coagulation can occur as a complication of abruptio placentae, and it is indicated by the petechiae and bleeding around the IV access site. Disseminated intravascular coagulation would also cause a low platelet count, a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), and a low fibrinogen level.

A. Painless red vaginal bleeding B. Intermittent abdominal pain following passage of bloody mucus C. Increasing abdominal pain with a nonrelaxed uterus D. Abdominal pain with scant red vaginal bleeding

Correct Answer is A

Explanation

Choice A reason: Painless red vaginal bleeding is the most characteristic finding of placenta previa, which is a condition where the placenta covers the cervical opening and can cause bleeding in the third trimester. Painless red vaginal bleeding occurs because the placenta is detached from the lower uterine segment as the cervix dilates or effaces, and the blood vessels are torn. The bleeding can be mild or severe, and it can recur or persist until delivery.

Choice B reason: Intermittent abdominal pain following passage of bloody mucus is not a finding that supports placenta previa, but rather a finding that suggests normal labor or preterm labor. Intermittent abdominal pain is caused by uterine contractions, which can be regular or irregular, and can increase in frequency, duration, and intensity. Bloody mucus is the mucus plug that is expelled from the cervix as it dilates or effaces, and it can be tinged with blood or streaked with blood.

Choice C reason: Increasing abdominal pain with a nonrelaxed uterus is not a finding that supports placenta previa, but rather a finding that indicates abruptio placentae, which is a premature separation of the placenta from the uterine wall. Increasing abdominal pain is caused by the bleeding and the hematoma formation behind the placenta, which can compress the uterine muscle and the nerve endings. Nonrelaxed uterus is a sign of uterine hypertonicity, which can reduce the blood flow and the oxygen delivery to the fetus.

Choice D reason: Abdominal pain with scant red vaginal bleeding is not a finding that supports placenta previa, but rather a finding that suggests ectopic pregnancy, which is a condition where the fertilized ovum implants outside the uterine cavity, usually in the fallopian tube. Abdominal pain is caused by the rupture of the tube and the bleeding into the peritoneal cavity, which can irritate the diaphragm and the abdominal wall. Scant red vaginal bleeding is a sign of implantation bleeding, which can occur when the fertilized ovum attaches to the tube wall.
