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 B

Explanation

Choice A reason: Uterine enlargement greater than expected for gestational age is not a typical manifestation of ectopic pregnancy, because the embryo is implanted outside the uterus, usually in the fallopian tube. The uterus may be slightly enlarged due to hormonal changes, but not more than expected for the gestational age.

Choice B reason: Unilateral, cramp-like abdominal pain is a common manifestation of ectopic pregnancy, because the embryo grows and stretches the fallopian tube, causing inflammation and irritation. The pain may be mild or severe, depending on the size and location of the ectopic pregnancy, and may radiate to the shoulder or back.

Choice C reason: Severe nausea and vomiting is not a specific manifestation of ectopic pregnancy, because it can be caused by other conditions, such as hyperemesis gravidarum, gastroenteritis, or appendicitis. The client may have mild nausea and vomiting due to hormonal changes, but not more than usual for the gestational age.

Choice D reason: Large amount of vaginal bleeding is not a usual manifestation of ectopic pregnancy, because the bleeding is usually internal, into the abdominal cavity. The client may have spotting or light bleeding due to the detachment of the endometrium, but not heavy or profuse bleeding.

A. Blunt force trauma B. Hypertension C. Gestational diabetes mellitus D. Cigarette smoking

Correct Answer is B

Explanation

Choice A reason: Blunt force trauma is a possible risk factor for placental abruption, which is a condition where the placenta detaches from the uterine wall and causes bleeding, pain, and fetal distress. However, blunt force trauma is not the most common risk factor, as it accounts for only a small percentage of cases. The most common causes of blunt force trauma are motor vehicle accidents, falls, or domestic violence.

Choice B reason: Hypertension is the most common risk factor for placental abruption, as it affects about 50% of cases. Hypertension can cause vasospasm and reduced blood flow to the placenta, which can weaken the attachment and lead to separation. Hypertension can be chronic, gestational, or related to preeclampsia.

Choice C reason: Gestational diabetes mellitus is not a risk factor for placental abruption, but rather a condition where the client develops high blood sugar levels during pregnancy and can cause complications, such as macrosomia, polyhydramnios, or neonatal hypoglycemia. Gestational diabetes mellitus does not affect the placental attachment or function.

Choice D reason: Cigarette smoking is a risk factor for placental abruption, as it can cause vasoconstriction and reduced oxygen delivery to the placenta, which can impair its growth and development. However, cigarette smoking is not the most common risk factor, as it affects about 25% of cases.
