When doing the first assessment of a male newborn, the nurse notes that the scrotum is large, edematous, and pendulous. What should this be interpreted as?
- A. A hydrocele
- B. An inguinal hernia
- C. A normal finding
- D. An absence of testes
Correct Answer: C
Rationale: A large, edematous, and pendulous scrotum in a term newborn, especially in those born in a breech position, is a normal finding. A hydrocele is fluid in the scrotum, usually unilateral, which usually resolves within a few months. An inguinal hernia may or may not be present at birth. It is more easily detected when the child is crying. The presence or absence of testes should be determined on palpation of the scrotum and inguinal canal. Absence of testes may be an indication of ambiguous genitalia.

The nurse observes that a new mother avoids making eye contact with her infant. What should the nurse do?
- A. Ask the mother why she wont look at the infant.
- B. Examine the infants eyes for the ability to focus.
- C. Assess the mother for other attachment behaviors.
- D. Recognize this as a common reaction in new mothers.
Correct Answer: C
Rationale: Attachment behaviors are thought to indicate the formation of emotional bonds between the newborn and mother. A mothers failure to make eye contact with her infant may indicate difficulties with the formation of emotional bonds. The nurse should perform a more thorough assessment. Asking the mother why she will not look at the infant is a confrontational response that might put the mother in a defensive position. Infants do not have binocularity and cannot focus. Avoiding eye contact is an uncommon reaction in new mothers.
Which characteristic is representative of a full-term newborns gastrointestinal tract?
- A. Transit time is diminished.
- B. Peristaltic waves are relatively slow.
- C. Pancreatic amylase is overproduced.
- D. Stomach capacity is very limited.

- A. 60 to 80 beats/min
- B. 80 to 100 beats/min
- C. 120 to 140 beats/min
- D. 160 to 180 beats/min
Correct Answer: C
Rationale: The pulse rate of the newborn varies with periods of reactivity. Usually the pulse rate is between 120 and 140 beats/min. Sixty to 100 beats/min is too slow for a newborn, and 160 to 180 beats/min is too fast for a newborn.
