A nurse is providing teaching to a client who has heart failure and a new prescription for furosemide. Which of the following statements should the nurse make?

• Endometritis – This uterine infection is one of the most common postpartum complications, especially following cesarean delivery and prolonged rupture of membranes. It often presents with foul-smelling lochia, uterine tenderness, and systemic signs of infection like fever and leukocytosis. This client’s presentation, including foul-smelling lochia and a WBC of 33,000/mm³, strongly supports this diagnosis.
• Mastitis – Typically associated with localized breast pain, redness, swelling, and systemic symptoms like fever. While the client has nipple discomfort and firm breasts, these are common postpartum findings during milk let-down and do not meet the criteria for mastitis, especially without signs of inflammation or localized breast infection.
• Pulmonary embolism – A PE generally presents with sudden-onset chest pain, dyspnea, tachypnea, and hypoxia. This client’s oxygen saturation is normal, lung sounds are clear, and there is no respiratory distress, making PE unlikely.
• Postpartum hemorrhage – Hemorrhage would present with excessive vaginal bleeding, hypotension, tachycardia, and possibly uterine atony. This client’s uterus is firm, lochia is moderate (not heavy), and vital signs are stable, so hemorrhage is not supported by the data.
• Lochia assessment – Foul-smelling lochia is a classic indicator of uterine infection. It points to endometritis when found with other risk factors like cesarean birth, prolonged labor, and signs of systemic inflammation.
• Elevated white blood cell count – A postpartum WBC count may be mildly elevated, but a level of 33,000/mm³ suggests infection. When combined with clinical symptoms like uterine tenderness and malodorous discharge, it supports a diagnosis of endometritis.
• Firm uterus at 1 cm above umbilicus – This finding is expected on postpartum day 3 and indicates normal uterine involution. A firm uterus rules out uterine atony and is not specific to infection or hemorrhage.
• Moderate nipple discomfort – Breast fullness and nipple tenderness are common in breastfeeding mothers, especially in the early postpartum period. This discomfort alone does not indicate mastitis or any systemic infection.

A. "You should take a dose every night at bedtime." Sublingual nitroglycerin is not taken on a routine schedule like bedtime. It is used as needed at the onset of chest pain or before activities that might trigger angina, not as a preventive nightly dose.
B. “You should take this medication with food." Sublingual nitroglycerin is placed under the tongue and absorbed directly into the bloodstream, bypassing the gastrointestinal system. It does not require administration with food.
C. "You may repeat a dose after five minutes." If chest pain persists after the first dose, the client may take one tablet every 5 minutes, up to a total of three doses within 15 minutes. If the pain continues after the third dose, emergency services should be contacted.
D. “You may crush this medication if needed." Sublingual tablets should never be crushed or swallowed, as this would prevent proper absorption through the oral mucosa and reduce the medication’s effectiveness in relieving acute chest pain.
