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. Cushing's syndrome: Prolonged use of corticosteroids can lead to iatrogenic Cushing's syndrome. Common features include weight gain (especially central), mood changes such as anxiety or irritability, insomnia, and physical changes like hirsutism (increased facial hair), moon face, and truncal obesity due to chronic hypercortisolism.
B. Adrenal insufficiency: This condition typically results from abrupt withdrawal of corticosteroids, leading to fatigue, hypotension, and electrolyte imbalances. It does not cause the excess cortisol-related symptoms described in this patient’s presentation.
C. Diabetes mellitus: While corticosteroids can raise blood glucose levels and increase the risk for diabetes, the described symptoms—particularly the weight distribution and hirsutism—are more indicative of Cushing’s syndrome than diabetes.
D. Dystonia: Dystonia involves involuntary muscle contractions causing repetitive movements or abnormal postures. It is not associated with the metabolic and hormonal effects caused by long-term corticosteroid use.
Correct Answer is ["10"]
Explanation
Desired dose = 20 mg
Available concentration = 10 mg per 5 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = Available dose / Available volume
= 10 mg / 5 mL
= 2 mg/mL
Volume to administer = Desired dose / Available concentration
= 20 mg / 2 mg/mL
= 10 mL
