The healthcare provider orders an IV solution of dextrose 5% in water at 100ml/hour. What would the flow rate be if the drop factor is 15 gtt = 1 ml?
- A. 5 gtt/minute
- B. 13 gtt/minute
- C. 25 gtt/minute
- D. 50 gtt/minute
Correct Answer: C
Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour · 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.

Which of the following procedures always requires surgical asepsis?
- A. Vaginal instillation of conjugated estrogen

- C. Nasogastric tube insertion

Correct Answer: B
Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity. Vaginal instillation of conjugated estrogen, nasogastric tube insertion, and colostomy irrigation do not always require surgical asepsis as they involve different levels of sterility and infection control measures.
