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) Calms spasm in the urinary tract: This statement is incorrect. Phenazopyridine primarily provides analgesic (pain-relieving) effects for the urinary tract but does not directly affect muscle spasms.

B) Provides an analgesic effect for irritated bladder mucosa: This is the correct response. Phenazopyridine is a urinary tract analgesic that acts locally to relieve pain, burning, and discomfort caused by irritation of the bladder mucosa. It does not treat the underlying infection but helps alleviate symptoms.

C) Eliminates urinary bacteria: This statement is incorrect. Phenazopyridine does not have antibacterial properties and does not eliminate urinary bacteria. Antibiotics are typically prescribed to treat urinary tract infections by targeting bacterial growth.

D) Use the medication after voiding after sexual intercourse: This statement is incorrect. While voiding after sexual intercourse can help reduce the risk of urinary tract infections (UTIs), phenazopyridine is not specifically indicated for this purpose. It is used primarily for symptom relief in cases of cystitis or other urinary tract irritations.

A. Use a twice a week dosing schedule. B. Take the medication early in the day. C. Stand and sit up slowly. D. Reduce daily fluid intake.

Correct Answer is C

Explanation

A) Tamsulosin is typically administered once daily, not on a twice-weekly dosing schedule. Instructing the client to adhere to the prescribed dosing frequency is essential for maintaining therapeutic blood levels of the medication and optimizing its effectiveness in managing urinary retention associated with benign prostatic hyperplasia (BPH).

B) While the timing of medication administration can impact its effectiveness, taking tamsulosin early in the day versus later in the day may not significantly affect its therapeutic action. The key consideration with tamsulosin is to maintain consistency in timing to ensure a steady plasma concentration of the drug.

C) Instructing the client to stand and sit up slowly is crucial because tamsulosin, as an alpha-blocker, can cause orthostatic hypotension, especially when first starting the medication or when increasing the dosage. By advising the client to change positions slowly, the nurse helps prevent falls and dizziness, which are common side effects associated with sudden drops in blood pressure.

D) Reducing daily fluid intake is not advisable, especially for a client with urinary retention. Maintaining adequate hydration is essential for overall health and urinary function. Tamsulosin works by relaxing the smooth muscles of the prostate and bladder neck, facilitating urine flow, but it does not directly affect fluid intake requirements.

Therefore, the most important instruction for the nurse to provide is to stand and sit up slowly to minimize the risk of orthostatic hypotension and associated complications.
