Correct Answer: C

Rationale: To calculate the correct dosage, first convert the infant's weight to kilograms: 17.6 lb = 8 kg. The prescribed dose is 5 mg/kg, so for an 8 kg infant, the total dose required is 40 mg. Since the available ibuprofen liquid is 100 mg/5 ml, to find out how many milliliters to administer, divide the total dose (40 mg) by the concentration of the liquid (100 mg/5 ml), which equals 2 ml. Therefore, the healthcare provider should administer 2 ml of ibuprofen to the infant.

Correct Answer: A

Rationale: Minimal change nephrotic syndrome (MCNS) is characterized by massive proteinuria, hypoalbuminemia, and edema. Proteinuria results from the loss of proteins, particularly albumin, in the urine, leading to hypoalbuminemia. The low oncotic pressure due to hypoalbuminemia causes fluid to shift into the interstitial spaces, resulting in edema. These clinical manifestations are classic signs of MCNS and help differentiate it from other renal conditions.
