A nurse is preparing to administer 0.9% NaCl 750 mL IV to infuse over 4 hours. The drop factor of the manual IV tubing is 10 gtt/mL. What is the flow rate in gtt/min? (Round to the nearest whole number & fill in the blank with the numerical value only).
The Correct Answer is ["31"]
Total volume to be infused = 750 mL
Total infusion time = 4 hours
Convert hours to minutes: 4 hours × 60 minutes/hour = 240 minutes
Drop factor = 10 gtt/mL
- Calculate the total number of drops needed:
Total drops (gtt) = Total volume (mL) × Drop factor (gtt/mL)
= 750 mL × 10 gtt/mL
= 7500 gtt
- Calculate the flow rate in drops per minute (gtt/min):
Flow rate (gtt/min) = Total drops (gtt) / Total infusion time (minutes)
= 7500 gtt / 240 minutes
= 31.25 gtt/min
- Round to the nearest whole number:
Rounding 31.25 to the nearest whole number gives 31.
= 31 gtt/min.

Correct Answer is A
Explanation
A. "Avoid alcohol while taking this medication as it may increase drowsiness.": Baclofen is a central nervous system depressant and can cause sedation. Alcohol can intensify this effect, increasing the risk of severe drowsiness, dizziness, or respiratory depression.
B. "You can abruptly stop taking this medication if you don't notice improvement.": Abrupt discontinuation of Baclofen can lead to withdrawal symptoms such as hallucinations, seizures, and rebound spasticity. The medication should be tapered under medical supervision.
C. "Baclofen doesn't cause drowsiness, so you can continue your normal activities without any restrictions.": Baclofen often causes drowsiness and dizziness, especially when therapy is initiated. Patients should be cautious with activities requiring alertness, such as driving.
D. "Take this medication only when you experience muscle spasms:": Baclofen is typically taken on a regular schedule to maintain therapeutic levels and control muscle spasms continuously. It is not used on an as-needed basis.
Correct Answer is B
Explanation
A. Request an order for an antiemetic: Although nausea is a symptom of digoxin toxicity, administering an antiemetic may mask a serious underlying problem. It should not be the first intervention without further assessment of the client’s condition.
B. Check the client's vital signs: Digoxin toxicity can cause bradycardia, hypotension, and arrhythmias. The client's symptoms (nausea, weakness, and visual disturbances) are classic signs of digoxin toxicity. Assessing vital signs is the priority to determine if there is immediate hemodynamic instability, which would guide further urgent interventions.
C. Suggest that the client rests before eating the meal: Fatigue may be related to digoxin toxicity or underlying heart failure, but suggesting rest delays necessary clinical assessment and does not address the potentially serious symptoms.
D. Request a dietitian consult: While nutrition is important for clients with CHF, the presence of nausea, weakness, and visual disturbances suggests possible digoxin toxicity, which requires immediate clinical evaluation not dietary consultation.
