A nurse is caring for a client who is 1 day postpartum and breastfeeding her newborn. The client reports sore nipples. Which of the following actions should the nurse take?

A: Administering an IV bolus of lactated Ringer's is typically used to correct electrolyte imbalances or as a volume expander in the case of blood loss. In peripartum cardiomyopathy, fluid overload should be avoided as it can exacerbate heart failure symptoms.
B: Misoprostol is used to prevent or treat postpartum hemorrhage, but it is not directly related to the management of peripartum cardiomyopathy.

C. Assess blood pressure twice daily:
While monitoring blood pressure is important for overall cardiovascular management, assessing it only twice daily is insufficient for a client with peripartum cardiomyopathy. This condition requires frequent and comprehensive monitoring of vital signs, fluid balance, and cardiac function to prevent complications.

D. Restrict daily oral fluid intake:
Restricting fluid intake is a key intervention in managing peripartum cardiomyopathy because it helps to prevent fluid overload, which could exacerbate heart failure. Clients with this condition often experience reduced cardiac output, and limiting fluids can reduce the strain on the heart and improve overall management of symptoms

Rationale:

A. A temperature of 37.4°C (99.3°F) may be within the normal range, but it can also indicate a fever, which is common with endometritis.

B. A WBC count of 9,000/mm3 is within the normal range, but it may be elevated in response to infection such as endometritis.

C. Scant lochia is not typically associated with endometritis; instead, clients with endometritis may have increased or foul-smelling lochia.

D. Uterine tenderness is a common finding in clients with endometritis, as the infection causes inflammation and discomfort in the uterine lining.
