A client is receiving a secondary IV infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["83"]
Rationale:
Total volume to be infused = 500 mL.
Infusion time in minutes = 2 hours × 60 minutes/hour
= 120 minutes.
Drop factor of the IV administration set = 20 gtt/mL.
- Calculate the flow rate in drops per minute (gtt/min).
Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min)
= (500 mL × 20 gtt/mL) / 120 min
= 10000 / 120 gtt/min
= 83.333... gtt/min.
- Round the answer to the nearest whole number.
= 83 gtt/min

Explanation
A. Monitor ETT markings between 22 and 26 cm at teeth line: While the placement marking on the ETT can be useful for initial placement, it is not the most reliable way to confirm correct positioning. ETT placement should always be verified by clinical assessment rather than relying solely on measurements.
B. Check for capillary refill of 3 seconds or less: Capillary refill is a general indicator of peripheral circulation and does not directly assess whether the ETT is properly placed in the trachea. It is not useful for confirming ETT placement.
C. Auscultate for presence of bilateral breath sounds: This is a key assessment to confirm that the ETT is properly placed. Bilateral breath sounds indicate that air is entering both lungs, suggesting that the tube is correctly positioned in the trachea and not in the esophagus.
D. Obtain a portable chest x-ray to verify ETT location: A chest x-ray is the gold standard for confirming the correct placement of the ETT. It provides an accurate visual confirmation of the tube’s position relative to the carina and the lungs.
E. Assess for symmetrical chest movement: Symmetrical chest movement is another important assessment to confirm proper ETT placement. If the ETT is correctly placed in the trachea, both sides of the chest will rise and fall equally with each breath, indicating effective ventilation.
Correct Answer is ["A","D","E","G"]
Explanation
Rationale for Correct Findings:
- Balancing periods of activity with rest: This indicates effective self-management and understanding of a key principle in managing rheumatoid arthritis. Maintaining this balance helps prevent overexertion and joint flares while preserving mobility and function.
- Client reports pain as 1 to 2 on a 0 to 10 pain scale in bilateral hands: The reduction in pain from a previous score of 3 to 1-2 indicates a positive response to treatment. Pain reduction is a key marker of progress in managing rheumatoid arthritis, especially with the initiation of methotrexate.
- She is tolerating weekly medication without side effects: Tolerating methotrexate without side effects is a positive outcome. Methotrexate is a cornerstone treatment for rheumatoid arthritis, and its ability to be well-tolerated suggests good disease control.
- The client is pleased with the improvements: The client’s satisfaction with her treatment and the improvements in her condition demonstrate effective management of her rheumatoid arthritis and a positive response to the prescribed interventions.
Rationale for Incorrect Findings:
- She has continued to garden, but crocheting is too painful: The client’s inability to crochet due to pain suggests that joint function is still limited in certain fine motor activities. This shows that while some improvement has been made, the disease still affects specific functions.
- She recently attended a large family wedding and became fatigued quickly: Fatigue is common in RA and suggests that the client’s energy levels still need better management. Overexertion could indicate a need for better pacing between rest and activity to avoid exacerbating symptoms.
- She has noticed "heartburn" about an hour after using ibuprofen for pain relief: Heartburn is a common side effect of NSAIDs like ibuprofen, which could lead to gastrointestinal irritation. This issue requires attention, as it could progress to more serious gastrointestinal complications.
