Answer to Question 1

ANS: C
The heart rate is counted for a full minute to determine whether arrhythmias or bradycardia is present. Fifteen to 30 seconds are too short for accurate assessment. Sixty seconds is sufficient to assess heart rate and rhythm.

Answer to Question 2

ANS: C
Between ages 6 and 8 months, fear of strangers and stranger anxiety become prominent and are related to infants' ability to discriminate between familiar and unfamiliar people. At 2 months, infants are just beginning to respond differentially to their mothers. The infant at age 4 months is beginning the process of separation-individuation, which involves recognizing the self and mother as separate beings. Twelve months is too late; the infant requires referral for evaluation if he or she does not fear strangers by this age.
