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 A

Explanation

A) Notify the healthcare provider of the passage of black stools: This is the correct response. Black stools can indicate gastrointestinal bleeding, which is a serious adverse effect of NSAID use. It's im’ortant for the client to report this symptom promptly to the healthcare provider for further evaluation and management.

B) Call the clinic if diarrhea or headache occur when taking esomeprazole: While it's im’ortant to report any adverse effects of medication to the healthcare provider, diarrhea and headache are not specific to esomeprazole and may not warrant immediate attention unless severe or persistent.

C) Once pain subsides, NSAID therapy can be resumed: This statement is incorrect. The client should avoid NSAIDs in the future, as they are likely the cause of the gastric pain and gastrointestinal bleeding. Resuming NSAID therapy would increase the risk of recurrent bleeding.

D) Resume a diet that consists of milk, cream, and bland foods: This statement is incorrect. While bland foods may be easier to tolerate during acute gastric pain, they do not address the underlying issue of gastrointestinal bleeding. Additionally, dairy products like milk and cream may exacerbate symptoms in some individuals.

Correct Answer is ["0.8"]

Explanation

The nurse should administer 0.8 mL of the enoxaparin sodium injection.

Here's th’ breakdown of the calculation:

Prescribed dose: 80 mg

Available medication: 60 mg/0.6 mL

The nurse needs to determine the volume of the available medication that delivers the prescribed dose of 80 mg. We can set up a proportion to find the desired volume (x):

Prescribed dose (mg) : Desired volume (mL) = Concentration (mg/mL) : Available volume (mL)

Plugging in the values:

80 mg : x mL = 60 mg/0.6 mL : 0.6 mL

To isolate x (desired volume), we can cross-multiply:

x mL x (60 mg/0.6 mL) = 80 mg x 0.6 mL

Simplifying the equation

0.6x mL = 48 mg

To find x (desired volume), we can divide both sides by 0.6 mL:

x mL = (48 mg) / (0.6 mL/mL) // Cancel out units (mg/mL)

x = 80 mL

However, the answer needs to be rounded to the nearest tenth since medication dosages are measured precisely.

Therefore, the nurse should administer 0.8 mL of the enoxaparin sodium injection.
