A nurse is caring for a client diagnosed with a complete hydatidiform mole who underwent suction curettage 2 days ago. Which nursing intervention is the priority for this client?
1Encourage the client to begin trying to conceive again in 3 months
2Monitor serial beta-hCG levels and educate about contraception for 1 year✓ 정답
3Schedule a follow-up appointment in 6 months for routine gynecologic care
4Recommend immediate fertility counseling to address conception concerns
해설
Monitoring serial beta-hCG levels is critical to detect malignant transformation to choriocarcinoma, and contraception for 1 year prevents interference with hCG monitoring. Other options are less urgent or premature.
A complete hydatidiform mole (CHM) is a form of gestational trophoblastic disease characterized by abnormal proliferation of trophoblastic tissue, resulting in a conceptus that typically lacks a viable fetus. As noted in the case report by Mujkanovic-Dzino et al., patients with CHM often present with markedly elevated beta-human chorionic gonadotropin (β-hCG) levels, uterine enlargement, and trophoblastic hyperplasia [1]. The critical concern following evacuation of a CHM is the potential for malignant transformation into gestational trophoblastic neoplasia (GTN). The same source highlights that the risk of developing persistent GTN following CHM is substantially higher than with a partial hydatidiform mole [1]. This elevated risk necessitates meticulous post-operative surveillance rather than routine follow-up.
Prioritizing Post-Molar Surveillance
The priority nursing intervention centers on monitoring for malignant sequelae and preventing a new pregnancy that would confound this surveillance. The standard of care, reflected in the management protocols of the studies provided, involves serial quantitative β-hCG monitoring. The prospective study by Soe et al. on preventing post-molar GTN reinforces this paradigm, as the primary outcome was the progression to GTN, which was assessed through β-hCG surveillance after molar evacuation [2]. A rising or plateauing β-hCG level is the primary indicator of developing GTN. Concurrently, reliable contraception is mandated to avoid a new pregnancy, which would cause a physiological rise in β-hCG and make it impossible to distinguish from a malignant process. The recommended duration of contraception is typically 12 months (1 year) to cover the period of highest risk for GTN development.
Why Other Options Are Incorrect
- Option 1: Encourage the client to begin trying to conceive again in 3 months. This is contraindicated. A new pregnancy within the surveillance window would elevate β-hCG levels, masking the critical early sign of GTN. The required contraceptive period is significantly longer, typically one year.
- Option 3: Schedule a follow-up appointment in 6 months for routine gynecologic care. This is insufficient and dangerous. Surveillance for GTN requires frequent, serial β-hCG monitoring that begins immediately after evacuation, not a single routine visit months later. The case report by Du and Wang describes an abdominal CHM diagnosed only after surgical exploration, underscoring how atypical and aggressive trophoblastic disease can be, reinforcing the need for close, early biochemical monitoring rather than delayed routine care .
- Option 4: Recommend immediate fertility counseling to address conception concerns. While psychosocial support and future fertility counseling are important components of holistic care, they are not the immediate clinical priority. The physiological safety concern of detecting a potentially life-threatening malignancy through β-hCG monitoring takes precedence over addressing conception concerns at this 2-day post-operative juncture.
The nurse must first ensure the client understands the critical medical rationale for β-hCG surveillance and strict contraception to prevent the life-threatening complication of GTN.

Vital Signs & Bleeding: Monitor for signs of hemorrhage or infection post-curettage.
beta-hCG Trend: Ensure weekly quantitative serum beta-hCG draws until three consecutive normal levels, then monthly for 6-12 months per protocol.
Patient Education: Assess understanding of the need for reliable contraception and the rationale for avoiding pregnancy.
Key Interventions & Rationale
Surveillance Compliance: Track beta-hCG results closely; a plateau or rise is the earliest indicator of GTN requiring oncology referral.
Contraception Mandate: Advise reliable hormonal contraception or barrier methods for a minimum of 12 months to prevent a new pregnancy from masking malignant markers.
Psychosocial Support: Address grief and anxiety related to pregnancy loss while reinforcing the life-saving purpose of strict monitoring.
Red Flags & Follow-Up
Danger Signs: Report persistent vaginal bleeding, pelvic pain, or respiratory symptoms immediately, which may indicate metastatic GTN.
Long-Term Plan: After the surveillance period concludes with normal beta-hCG levels, the client can discuss future pregnancy planning and preconception counseling.
Interprofessional Coordination: Collaborate with gynecologic oncology and social work to ensure medical and emotional needs are met.
Complete Hydatidiform Mole — A form of gestational trophoblastic disease with abnormal trophoblastic proliferation, usually lacking a viable fetus, and carrying a higher risk of malignant transformation to gestational trophoblastic neoplasia.
Gestational Trophoblastic Neoplasia (GTN) — A malignant form of gestational trophoblastic disease that can develop after a molar pregnancy, detected primarily by rising or plateauing beta-hCG levels post-evacuation.
beta-hCG Surveillance — Serial quantitative measurement of beta-human chorionic gonadotropin levels after molar evacuation to monitor for malignant sequelae; the standard of care for post-molar follow-up.
