The healthcare provider prescribes the antibiotic surgical prophylaxis protocol for a client who weighs 90 kg. The protocol is cefazolin 2 grams/100 mL. 0.9% normal saline over 1 hour for clients weighing less than 285.5 pounds or cefazolin 3 grams/100 mL 0.9% normal saline over 90 minutes for clients weighing greater than 265.5 pounds. The nurse should program the pump to deliver how many mL/hr? (Enter number value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["100"]

Since the client weighs 90 kg, let’s first convert their weight to pounds to determine the appropriate cefazolin dosage:

Conversion factor: 1 kg = 2.205 pounds

Client weight (pounds) = 90 kg x 2.205 pounds/kg = 198.45 pounds (rounded to two decimals)

Now, comparing the client’s weight (198.45 pounds) to the weight threshold (265.5 pounds):

Client weight is less than the threshold (198.45 pounds < 265.5 pounds).

Therefore, the appropriate dosage is:

Cefazolin 2 grams/100 mL 0.9% normal saline over 1 hour.

The pump rate is determined by the total volume of the IV fluid and the infusion time.

We are not given the specific bag size, but typically these come in 100 mL or 500 mL volumes.

Assuming a 100 mL bag (which aligns with the concentration provided):

Total volume of IV bag: 100 mL

Infusion time: 1 hour

Calculation:

Pump rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Pump rate (mL/hr) = 100 mL / 1 hour = 100 mL/hr

Therefore, the nurse should program the pump to deliver 100 mL/hr.

Correct Answer is B

Explanation

A) Provide information on increasing medication dosage if ketoacidosis occurs: While it is important for clients with diabetes to understand the signs and symptoms of diabetic ketoacidosis (DKA) and how to respond, increasing insulin dosage on their own without healthcare provider guidance could be dangerous. Adjusting insulin dosage should always be done under the direction of a healthcare provider.

B) Teach the client self-injection skills for daily subcutaneous administration: Insulin glargine is a long-acting insulin used for basal (background) insulin coverage in clients with diabetes. Teaching the client how to self-administer insulin injections is essential for effective management of diabetes, especially when using long-acting insulin formulations like insulin glargine. Proper injection technique, site rotation, and storage of insulin are important aspects of this teaching.

C) Demonstrate how to select dose based on before meal blood sugar readings: Insulin glargine is typically administered once daily at the same time each day and is not adjusted based on before meal blood sugar readings. Instead, it provides a steady level of insulin over 24 hours to help control blood sugar levels between meals and overnight.

D) Explain to the family how to inject this medication for severe hypoglycemia: Insulin glargine is not used for the treatment of severe hypoglycemia. Instead, it is a long-acting insulin used to maintain basal insulin levels in clients with diabetes. Severe hypoglycemia is treated with fast-acting glucose sources such as oral glucose tablets, gel, or glucagon injections, and the family should be educated on these treatments instead.

Correct Answer is ["133"]

Explanation

The nurse should program the infusion pump to deliver approximately 133 ml/hour.

Here's how we can calculate the rate:

Total volume of infusion (mL): 200 mL (dextrose 5% in water)

Infusion time (minutes): 90 minutes

We need to convert the infusion time to hours for the pump rate calculation:

Infusion time (hours) = 90 minutes / 60 minutes/hour

Infusion time (hours) = 1.5 hours

Now, calculate the flow rate (mL/hr):

Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours)

Flow rate (mL/hr) = 200 mL / 1.5 hours

Flow rate (mL/hr) = 133.33 mL/hr (round to nearest whole number as requested)

Therefore, the nurse should program the pump to deliver 133 ml/hour.
