A nurse is discussing hormones with a client who is pregnant.
Which of the following statements should the nurse make?
Early in pregnancy, your body secretes a hormone called progesterone, which is what is tested to confirm pregnancy.
You may experience swelling due to decreasing estrogen levels throughout pregnancy.
Prolactin levels rise to prepare the breasts for lactation, which can cause an increase in breast size.
Human chorionic gonadotropin helps your cervix become soft as your body prepares for labor.
The Correct Answer is C
Choice C rationale
Prolactin is a hormone secreted by the anterior pituitary gland that progressively increases throughout pregnancy. Its primary biological role is to stimulate the growth of mammary alveolar tissue and promote the synthesis of milk proteins. The rising levels lead to noticeable physical changes, including increased breast volume and tenderness. While high progesterone levels inhibit actual milk production during pregnancy, the prolactin ensures the breast architecture is fully prepared for lactation immediately after delivery.
Choice A rationale
This statement is scientifically inaccurate because human chorionic gonadotropin, not progesterone, is the hormone detected in maternal blood and urine to confirm pregnancy. HCG is produced by the syncytiotrophoblast cells of the placenta shortly after implantation. Progesterone is indeed vital for maintaining the uterine lining and preventing contractions, but it is not the biomarker used in standard pregnancy tests. Normal progesterone levels vary significantly throughout the menstrual cycle and the different trimesters.
Choice B rationale
Estrogen levels actually increase significantly throughout pregnancy rather than decreasing. Estrogen promotes vasodilation and increases blood flow to the uterus, but it also contributes to salt and water retention in the interstitial tissues. This physiological increase in estrogen, combined with increased venous pressure from the enlarging uterus, is a primary cause of dependent edema or swelling in the extremities. A decrease in estrogen would not be a typical finding in a healthy pregnancy.
Choice D rationale
Human chorionic gonadotropin is primarily responsible for maintaining the corpus luteum during the first trimester to ensure continued progesterone production. It does not play a direct role in cervical ripening. Cervical softening, or effacement, is primarily mediated by prostaglandins and the hormone relaxin, which break down collagen fibers in the cervix. These changes allow the cervix to become thin and pliable in preparation for the mechanical stresses of labor and fetal passage.

Correct Answer is A
Explanation
Choice A rationale
Gonadotropin therapy involves the administration of follicle stimulating hormone and luteinizing hormone to induce ovulation. This pharmacological intervention can trigger an exaggerated response in the ovaries, leading to the development of multiple follicles. The resulting high levels of estradiol and vasoactive substances, such as vascular endothelial growth factor, increase capillary permeability. This shift of fluid from the intravascular space to the extravascular compartments defines the clinical presentation of ovarian hyperstimulation syndrome.
Choice B rationale
Hydrosalpinx refers to a distal fallopian tube obstruction where the tube becomes distended and filled with serous fluid. While this condition significantly impacts fertility by preventing the egg from reaching the uterus or interfering with embryo implantation, it does not involve systemic hormonal overstimulation or the rapid follicular growth seen in OHSS. It is a structural tubal pathology rather than a complication of systemic ovulation induction medications or a driver of acute ovarian enlargement.
Choice C rationale
Oligoovulation is a condition characterized by infrequent or irregular ovulation, often associated with polycystic ovary syndrome or hormonal imbalances. While patients with oligoovulation are often candidates for fertility treatments that could lead to OHSS, the condition of oligoovulation itself is a baseline state of reproductive dysfunction. It represents a lack of regular follicular development rather than the dangerous, hyperactive follicular response and fluid shifts that characterize the acute onset of OHSS.
Choice D rationale
Intrauterine insemination is a procedure where concentrated sperm is placed directly into the uterus to facilitate fertilization. The assessment or the procedure itself is a mechanical process and does not cause the systemic vascular changes associated with OHSS. OHSS is specifically triggered by the medications used to stimulate the ovaries prior to the procedure, such as human chorionic gonadotropin or gonadotropins, rather than the physical act of insemination or its clinical assessment.
Correct Answer is A
Explanation
Choice A rationale
Immediate documentation is a fundamental principle of nursing practice to ensure the integrity of the medical record and prevent medication errors. Documentation serves as a legal record of care provided and facilitates communication among the healthcare team. Delayed charting increases the likelihood of omitting details or, more dangerously, another provider administering a duplicate dose because the previous administration was not yet recorded, thereby compromising patient safety and clinical outcomes.
Choice B rationale
While monitoring the client's response to medication is a critical nursing responsibility, it is a separate process from the documentation of the administration itself. The act of giving the drug must be recorded at the time it occurs. Waiting for a response could lead to a significant time gap, resulting in an inaccurate timeline within the health record. Subsequent observations or adverse reactions should be charted as follow-up notes rather than delaying the initial entry.
Choice C rationale
Documentation at the end of a shift is a dangerous practice that violates the standards of professional nursing. It relies heavily on memory, which is fallible in a busy clinical environment, and leads to inaccuracies regarding the exact timing of doses. Furthermore, it leaves the medical record incomplete for the majority of the day, meaning other staff members lack real-time data to make informed decisions about the patient's ongoing care plan.
Choice D rationale
Recording information in a personal log for later transfer is inappropriate and poses a risk to patient confidentiality and data accuracy. Double charting or transferring notes increases the risk of transcription errors and violates HIPAA regulations if personal logs are not secured. The electronic health record is the only legal and authorized location for clinical data; therefore, all interventions must be entered directly into the primary system to ensure data security and availability.
