Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.

Correct Answer: D

Rationale: In a postpartum client with a perineal hematoma, assessing heart rate and blood pressure is crucial as it can help determine the client's circulatory status. A perineal hematoma has the potential to cause significant blood loss leading to hypovolemia. Monitoring vital signs like heart rate and blood pressure can provide immediate information on the client's hemodynamic stability and guide further interventions if needed.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to inform and assure the mother that this weight loss is normal. Newborns can lose up to 10% of their birth weight in the first few days after birth, which is attributed to fluid loss and adjustment to life outside the womb. This weight loss is typically regained within the first two weeks of life. It is crucial for the nurse to educate and provide reassurance to the mother about this common occurrence in newborns.

Correct Answer: C

Rationale: Palpating the anterior fontanel for tension and bulging is essential to assess for increased intracranial pressure, which could be indicated by the enlarged head circumference. This assessment can help identify potential neurological issues that need prompt attention.
