The nurse calculates that 0.74 mi of filgrastim must be administered to a client subcutaneously. The client weights 165 lbs. What length and gauge of needle is best to administer this medication?
2 inches 21 gauge
1 1/2 inch 27 gauge
5/8 inch 25 gauge
1/4 inch 19 gauge
The Correct Answer is C
A. 2 inches 21 gauge: This option is too long and too large in gauge for subcutaneous administration. Typically, a longer needle is not necessary for subcutaneous injections, especially for standard adult adipose tissue.
B. 1 1/2 inch 27 gauge: While this gauge is acceptable, the length is still longer than typically required for subcutaneous injections. A 1 1/2 inch needle is more suited for intramuscular injections.
C. 5/8 inch 25 gauge: This is the most appropriate choice for a subcutaneous injection. A 5/8 inch needle is typically adequate for subcutaneous tissue in adults, and a 25 gauge needle provides a suitable size for comfort while allowing the medication to be administered effectively.
D. 1/4 inch 19 gauge: This option is not suitable for subcutaneous injections. A 1/4 inch length is too short for effective penetration into subcutaneous tissue, and a 19 gauge needle is larger than necessary, which could increase discomfort.

Correct Answer is ["480"]
Explanation
To calculate the infusion rate, you need to determine the total volume to be infused and the time over which it will be infused.
Total volume to be infused = 200 mL
Time for infusion = 25 minutes
Infusion rate = Total volume / Time Infusion rate = 200 mL / 25 minutes = 8 mL/min
To convert this to mL/hour (since infusion pumps are typically set in mL/hour): Infusion rate = 8 mL/min × 60 minutes/hour = 480 mL/hour
Correct Answer is B
Explanation
A) Pedal pulses are +1 bilaterally: While this may indicate decreased perfusion, it is not an immediate concern that typically requires reporting before a cardiac angiogram. This finding should be monitored but does not usually contraindicate the procedure.
B) Client has multiple food allergies: This information is critical to report prior to the procedure, especially if any of the allergies pertain to medications or contrast agents used during the angiogram. Knowing about allergies can help prevent potential allergic reactions during the procedure.
C) Admission blood pressure is 110/70: This blood pressure reading is within an acceptable range for most patients. While the healthcare provider should be aware of baseline vitals, this alone does not necessitate immediate reporting.
D) Client is slightly anxious: While anxiety is important to acknowledge and may require intervention, it is common for clients undergoing procedures. This does not typically need to be reported urgently to the healthcare provider prior to the angiogram.
