A nurse is preparing to administer 0.9% 1L to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/ml. The nurse should set the manual IV infusion to deliver howmany gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["31"]
Flow rate (gtt/min)= Total volume / Time×Drop factor (gtt/mL)
Given:
- Total volume = 1000 mL (1 L)
- Time = 8 hours × 60 minutes = 480 minutes
- Drop factor = 15 gtt/mL
- Flow rate (gtt/min)= 1000 / 480×15= 31.25 (gtt/mL)
Answer: 31 gtt/min (rounded to the nearest whole number)

Correct Answer is B
Explanation
A. Collect a stool sample from the toddler: This is important but not the priority. Dehydration status must be assessed first.
B. Determine if the toddler is voiding: Assessing for urination helps evaluate hydration status and guides fluid replacement.
C. Initiate isotonic fluids with 20 mEq/L potassium chloride: Potassium should not be added until kidney function and voiding are confirmed.
D. Request evaluation of the toddler’s serum electrolytes: This is important but comes after assessing hydration and kidney function.
Correct Answer is B
Explanation
A. Polyuria: Nephrotic syndrome typically causes oliguria, not polyuria.
B. Periorbital edema: Fluid retention due to hypoalbuminemia commonly manifests as periorbital edema, especially in the morning.
C. Orange-tinged urine. This is not a characteristic of nephrotic syndrome. Urine may appear foamy due to proteinuria.
D. Hypertension: While hypertension can occur in some renal disorders, it is not a primary feature of nephrotic syndrome, which is characterized by edema, hypoalbuminemia, and proteinuria.
