Mild cramping during breastfeeding **정답: 3** ## 해설 Endometritis is characterized by uterine tenderness with foul-smelling lochia, indicating infection of the endometrial lining. Other findings like breast tenderness or normal lochia rubra are typical postpartum changes and not specific to endometritis. ## 심화 해설 Understanding Endometritis in the Postpartum Period The scenario describes a client with multiple risk factors for a postpartum uterine infection. A prolonged labor of 18 hours, multiple vaginal examinations, and premature rupture of membranes (PROM) for 12 hours before delivery all compromise the natural barriers to infection, allowing microorganisms to ascend into the uterine cavity. Endometritis, an infection of the uterine lining, is a primary concern in such cases, typically presenting 2 to 5 days postpartum. While bacteria are the usual causative organisms, rare cases of viral endometritis, such as from herpes simplex virus (HSV), have been documented, especially when a patient is unresponsive to conventional antibiotic therapy [1]. Analysis of Assessment Findings The key to answering this question lies in distinguishing the classic clinical triad of endometritis from normal postpartum physiological changes and other common conditions. - Option 1: Breast tenderness and engorgement. This is a typical physiological response to the onset of lactogenesis II, commonly occurring around 48 to 72 hours postpartum. It is a sign of breast fullness and is not indicative of a uterine infectious process. - Option 2: Lochia rubra with small clots. Lochia rubra is the normal vaginal discharge consisting of blood and decidual debris expected during the first 3 to 4 days after delivery. The presence of small clots, especially when the client is ambulating or after lying down for a period, is a common and benign finding. - Option 3: Uterine tenderness with foul-smelling lochia. This is the hallmark presentation of postpartum endometritis. The infection causes inflammation of the endometrium, leading to a tender, boggy, and poorly contracted uterus on palpation. The offensive odor of the lochia is a direct result of bacterial metabolism and is a critical distinguishing sign. This aligns with the reported initial symptoms of postpartum pyometra, which include fever, lower abdominal pain, and foul-smelling lochia [2]. The combination of pain and malodorous discharge is highly specific for an intrauterine infection. - Option 4: Mild cramping during breastfeeding. Known as "afterpains," this is caused by the release of endogenous oxytocin during breastfeeding, which stimulates uterine contractions. This is a normal and expected finding, particularly in multiparous women, as the uterus works to involute. While it can be uncomfortable, it is a physiological process, not a sign of infection. Clinical Reasoning and Priority Finding The nurse must synthesize the client's risk factors with the clinical presentation. The prolonged labor, multiple vaginal examinations, and PROM create a direct pathway for pathogen invasion. When this history is combined with a physical assessment, the finding that most directly signals an infectious complication is the presence of a tender uterus accompanied by foul-smelling lochia. This finding is the most indicative of endometritis because it reflects the underlying pathophysiology: microbial invasion of the endometrial tissue leading to inflammation, pain, and purulent, malodorous drainage. While puerperal sepsis is a severe progression of this infection and a significant contributor to maternal mortality in some regions , early identification of the localized infection through signs like uterine tenderness and foul-smelling lochia is the critical first step for prompt intervention.References (research sources) - [1]Not Just a Cold Sore: Postpartum Herpes Simplex Virus Endometritis.Research articleMoore O, Cottrell J.

She now reports pelvic discomfort and malaise. Assessment Focus - **Vital signs:** Monitor for fever (temperature ≥38°C / 100.4°F), the most common early sign of endometritis. - **Fundus:** Palpate for uterine tenderness, subinvolution (boggy, higher-than-expected fundal height), and poor contraction. - **Lochia:** Assess color, amount, and odor. Foul-smelling, purulent lochia is a hallmark sign. - **Pain:** Differentiate normal afterpains from constant, worsening uterine tenderness. Nursing Actions - Notify the provider immediately if the classic triad (fever, uterine tenderness, foul lochia) is present. - Obtain cultures (endometrial or lochia) if ordered before starting antibiotics. - Administer broad-spectrum IV antibiotics (e.g., clindamycin + gentamicin) as prescribed. - Encourage semi-Fowler’s position to promote lochia drainage. - Monitor for signs of sepsis (tachycardia, hypotension, chills) if infection progresses. Patient Education - Explain the importance of completing the full antibiotic course even if symptoms improve. - Teach hand hygiene and perineal care (front-to-back wiping, frequent pad changes). - Report worsening symptoms: increased bleeding, severe pain, or fever above 38°C. - Rest and increased fluid intake support recovery; breastfeeding can usually continue unless contraindicated by specific medications. ## 핵심 개념 - **Endometritis** — Infection of the uterine lining, typically presenting 2–5 days postpartum with fever, uterine tenderness, and foul-smelling lochia. - **Lochia rubra** — Normal postpartum vaginal discharge consisting of blood and decidual debris, lasting for the first 3–4 days after delivery. - **Premature rupture of membranes (PROM)** — Rupture of the amniotic sac before the onset of labor, increasing the risk of ascending infection. ## 같은 주제 문제 - [A postpartum client is being assessed for possible endometritis.
