Final answer:
The nursing diagnosis for a pediatric patient with a cleft palate that should be addressed first according to Maslow's hierarchy of needs is 'Altered nutrition: Less than body requirements' due to the risk of malnutrition.
Step-by-step explanation:
According to Maslow's hierarchy of needs, the most fundamental needs must be met before addressing higher-level needs. In the context of a pediatric patient with a cleft palate, the nursing diagnosis that must be prioritized is related to the physiological necessity for adequate nutrition and the prevention of immediate health risks. Therefore, Altered nutrition: Less than body requirements due to the difficulty in suckling and the associated risk for malnutrition should be addressed first.
A cleft palate, a condition that occurs from a failure of the palatine bones to fuse properly during embryonic development, can lead to a gap between the nasal and oral cavities. This condition affects approximately 1:2500 births and can severely impact the infant's ability to feed efficiently, increasing the risk for malnutrition. Surgical repair is required to correct the defect, but until then, ensuring the child receives adequate nutrition is crucial.
