Answer to Question 1
ANS: C
Development proceeds at a slower rate during embryonic stage indicates the nurse needs to follow up to correct the misconception. From the moment of conception until birth, human development proceeds at a predictive and rapid rate. All the rest of the information is correct and does not need follow-up. Development proceeds in a cephalocaudal and proximal-distal pattern.
Answer to Question 2
ANS: B
Size increases rapidly during the first year of life. Birth weight doubles in approximately 5 months and triples by 12 months. This infant should weigh at least 18 (6 3) pounds by this calculation. This child needs the nurse to intervene for further assessment. Height increases an average of 1 inch during each of the first 6 months and about 1/2 inch each month until 12 months: 21 + 6 + 3 = 30 (30 inches is the predicted height). Patterns of body function are just now starting to stabilize. It is quite normal for a 12-month-old child to not be potty-trained or walking up stairs yet. These milestones usually occur in the toddler period of development (12 to 36 months).
