A client who weighs 65 kg receives a prescription for lorazepam 44 mcg/kg intravenously to be administered 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.4"]

Calculate the total dosage required: 44 mcg/kg * 65 kg = 2860 mcg. Convert mcg to mg: 2860 mcg ÷ 1000 = 2.86 mg.

Divide by concentration: 2.86 mg ÷ 2 mg/mL = 1.43 mL.

Considering the vial contains 2 mg/mL, the nurse should administer around 1.43 mL, which can be rounded to 1.4 mL.

Correct Answer is ["200"]

Explanation

To calculate the mL/hour for the erythromycin infusion, we first need to determine the infusion rate in mL/minute.

The infusion is to be completed over 30 minutes, which is equal to 0.5 hours. Next, we divide the total volume (100 mL) by the total time (0.5 hours) to get the infusion rate in mL/hour:

Infusion rate = Total volume / Total time

Infusion rate = 100 mL / 0.5 hours Infusion rate = 200 mL/hour

Therefore, the nurse should program the infusion pump to deliver the erythromycin infusion at a rate of 200 mL/hour.

A. Hematocrit. B. Platelet count. C. Creatinine level. D. White blood cell (WBC) count.

Correct Answer is D

Explanation

The presence of purulent drainage at the wound indicates a potential infection, and monitoring the client's WBC count is an important laboratory value to assess for signs of infection. An elevated WBC count, specifically an increase in the neutrophil count (neutrophilia), can indicate an active infection and provide important information for the healthcare provider when evaluating the wound.

While hematocrit, platelet count, and creatinine level are essential laboratory values to assess the client's overall condition, they may not provide specific information regarding the presence of infection or purulent drainage at the wound site.
