What information should the nurse give a mother regarding the introduction of solid foods during infancy?

Correct Answer: B

Rationale: The correct answer is B. When introducing solid foods to infants, it is important to introduce one food item at a time, with intervals of 4 to 7 days between each new food. This allows for the identification of any potential food allergies or intolerances. It is important to proceed gradually and monitor for any adverse reactions.

Correct Answer: C

Rationale: Penicillin is the most frequently implicated drug in serum sickness-like reactions.

Correct Answer: D

Rationale: Heart failure is not a common feature of TOF due to the obstructed right ventricular outflow, which limits pulmonary overcirculation.

Correct Answer: C

Rationale: Breastfeeding actually reduces the risk of sudden infant death syndrome (SIDS), while sleeping on the stomach, smoking, overheating, and prematurity increase the risk.

Correct Answer: A

Rationale: First-line treatment for acute asthma exacerbations includes oxygen, nebulized β2 agonists (albuterol), and systemic corticosteroids. Aminophylline and magnesium sulfate are reserved for severe, refractory cases.
