A nurse is reinforcing teaching with a client about the care of their newborn's umbilical cord. Which of the following statements by the client indicates an understanding of the teaching?

A) Incorrect- A reddened area on the calf might indicate a potential blood clot (deep vein thrombosis), which is important to assess but may not be the highest priority.
B) Incorrect- Painful uterine contractions during breastfeeding can be a normal response due to oxytocin release during breastfeeding and might not require immediate reporting.
C) Correct - A urinary output of 125 mL in 4 hours is significantly low and could indicate inadequate fluid intake, potential urinary retention, or other issues that need prompt attention. It is a sign of impaired renal function. This could indicate dehydration, blood loss, infection, or kidney injury. The nurse should assess the client's fluid intake and output, vital signs, urine specific gravity, and serum electrolyte levels. The nurse should also monitor the client for signs of hypovolemia, such as tachycardia, hypotension, and decreased skin turgor.
D) Incorrect- Changing a perineal pad every 2 hours is within the normal range for postpartum bleeding and might not require immediate reporting.

Rationale:

A) Incorrect - Applying oxygen is not the priority action in the case of excessive vaginal bleeding and a boggy uterus. Oxygen therapy would be appropriate if there were signs of respiratory distress or decreased oxygen saturation, but it does not directly address the primary concern of uterine atony and bleeding.
B) Incorrect - Administering methylergonovine might be appropriate, but the priority is to address the uterine atony with fundal massage first. Fundal massage helps stimulate uterine contractions and control bleeding, which is crucial in this scenario.
C) Incorrect - Encouraging the client to empty her bladder is important, but it is not the first action to take in the case of excessive bleeding and uterine atony. Immediate intervention to control the bleeding takes precedence.
D) Correct - Initiating fundal massage is the priority action in this situation. A boggy uterus with excessive vaginal bleeding indicates uterine atony, which is a potentially life-threatening condition requiring immediate intervention to prevent further bleeding.
Fundal massage helps the uterus contract and control bleeding. Addressing uterine atony is critical to prevent further hemorrhage and stabilize the client's condition.
