A nurse is preparing a sterile field for a client who requires a dressing change. Which of the following actions should the nurse plan to take?

Rationale for Correct Choices

• Endometritis: This uterine infection is common after cesarean delivery, especially with prolonged rupture of membranes. The client’s uterine tenderness, elevated fundus, boggy consistency, and foul-smelling lochia are hallmark signs of endometritis, making it the most likely diagnosis.
• Uterus and lochia: The presence of a tender uterus that is elevated above the umbilicus and only firms with massage, combined with dark, malodorous lochia, strongly suggests infection of the uterine lining. These findings point specifically to endometritis rather than general postpartum changes.

Rationale for Incorrect Choices

• Mastitis: Although the client reports heavy, warm breasts with nipple discomfort, there is no breast erythema, localized swelling, or high-grade fever typical of mastitis. These symptoms are likely due to engorgement related to lactation rather than infection.
• Pneumonia: The client’s respiratory assessment shows clear lungs with only slight basal changes common postoperatively. There are no signs of cough, sputum production, hypoxia, or respiratory distress, which makes pneumonia an unlikely cause of her symptoms.
• Fever: A temperature of 38.2°C is above normal, but mild postpartum fever can have various causes, including engorgement, dehydration, or early infection. Fever alone is not specific enough to confirm a diagnosis without targeted findings.
• WBC count: Although an elevated WBC of 33,000/mm³ raises concern, postpartum leukocytosis can be physiologic or related to many infections. It is not diagnostic of endometritis without more specific correlating signs like uterine tenderness and abnormal lochia.

Rationale for correct choices:

• Administer oxygen at 2 L/min via nasal cannula: The client's oxygen saturation has dropped to 92% on room air, indicating mild hypoxia. Supplemental oxygen should be administered to improve myocardial oxygenation and reduce ischemia while further interventions are being prepared.
• Administer sublingual nitroglycerin: Nitroglycerin is a first-line medication for chest pain caused by suspected myocardial ischemia. It promotes vasodilation, reduces myocardial oxygen demand, and provides symptom relief. Administering it promptly can help prevent further cardiac damage.

Rationale for incorrect choices:

• Request a prescription for an increase in statin medication: Although the client has hyperlipidemia, increasing the statin dose is not an immediate priority during an acute chest pain episode. Lipid management is important long-term but does not address the acute ischemic event.
• Prepare the client for cardiac catheterization: Cardiac catheterization may eventually be necessary, but it is not the nurse’s first action. The priority is to stabilize the client’s symptoms (oxygenation and pain) before preparing for any invasive diagnostic or therapeutic procedure.
• Check a STAT cardiac troponin: Troponin has already been obtained and is within normal limits at this point. While serial troponins may be needed later, immediate nursing priorities focus on symptom relief and oxygenation rather than repeating the test right away.
• Request a prescription for a beta-blocker: Beta-blockers may be used in the treatment of suspected myocardial infarction to reduce heart rate and myocardial oxygen demand. However, their initiation typically follows pain relief, oxygenation, and diagnostic confirmation, not as the first nursing action.
