Rationale: Putting the newborn to breast is the highest priority intervention in this scenario. It helps stimulate uterine contractions in the mother, which aids in controlling postpartum bleeding. Additionally, placing the newborn to breast promotes bonding between the mother and infant, provides comfort to the baby, and facilitates the initiation of breastfeeding. Ensuring the well-being of both the mother and the newborn is essential in this critical situation.

Correct Answer: A

Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs � 2.2 = 10 kg. The maximum dose based on weight would be 10 kg 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg � 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg � 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.

Correct Answer: B

Rationale: In glomerulonephritis, it is crucial to restrict the child's diet, particularly avoiding foods high in potassium like strawberries. Potassium restriction is essential because impaired kidney function in glomerulonephritis can lead to potassium retention, potentially causing hyperkalemia. Therefore, the nurse should restrict the child's diet to manage their condition effectively.
