Rationale: At 6 months, infants are generally ready to start eating iron-fortified cereals as their iron stores begin to deplete. Introducing iron-fortified cereals at this age helps meet the infant's nutritional needs, particularly for iron, which becomes deficient as the infant's iron reserves diminish. It is a safe and appropriate first food to introduce to infants around 6 months of age, along with continued breastfeeding or formula feeding.

Correct Answer: D

Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 X = 0.25 1000. X = (0.25 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution.

Correct Answer: A

Rationale: In this scenario, the best intervention is to ask the mother to stop feeding, comfort the infant, and then assist her in helping the baby latch on. Stopping the feeding and providing comfort can reduce the infant's frustration and create a calmer environment for successful breastfeeding.
