Explanation:

Question 12

For blood transfusion, the recommended catheter gauge is typically 14 - 20 gauge as it allows for efficient flow of blood products. Smaller gauges (like 22 - 24 or 20 - 26) may be too narrow, and larger gauges (10 - 12) are usually not necessary for routine blood transfusion.

Transfusion reactions, especially allergic ones, commonly present with itching and rash. Bradycardia is not typical, high urine output is not a sign, and constipation is unrelated to transfusion reactions.

During blood transfusion, vital signs are checked after the first 15 minutes, then every hour, and upon completion. This is to monitor for any transfusion - related reactions. Checking only before/after or at fixed 15/30 - minute intervals is not the standard practice.

Answer:

B. 14 - 20 gauge
