The nurse is documenting the obstetrical history of a client who is currently 18 weeks pregnant utilizing the GTPAL system.
Past obstetrical history includes a vaginal delivery at 26 weeks of a newborn who did not survive, a miscarriage at 8 weeks, and one living child who was delivered at 38 weeks.

Choice A rationale

The use of an antidepressant, such as a selective serotonin reuptake inhibitor (SSRI), can occasionally cause sexual dysfunction or menstrual irregularities, like amenorrhea or menorrhagia, as a side effect due to its influence on neurotransmitter levels, particularly serotonin. The client's heavy and irregular menses may be a consequence, warranting further inquiry regarding the specific drug, dosage, and start date relative to the onset of the menstrual issues to assess for a correlation. This may require further investigation.

Choice B rationale

Irregular menses, characterized by variability in cycle length and bleeding patterns (normal cycle length is 21-35 days), are concerning, especially when coupled with heavy bleeding (menorrhagia) and a history of a sexually transmitted infection (STI) like trichomoniasis, which suggests potential pelvic inflammatory disease (PID). This may indicate an underlying endocrine disorder such as polycystic ovary syndrome (PCOS) or other structural issues, necessitating further investigation, including hormonal assays or pelvic ultrasound, to determine the etiology.

Choice C rationale

A blood pressure of 108/74 mmHg is considered within the normal, healthy range for an adult (normal is generally ≤ 120/80 mmHg). Hypotension is typically defined as a systolic pressure <90 mmHg or a diastolic pressure <60 mmHg, or a drop in blood pressure that causes symptoms. Therefore, this specific vital sign is reassuring and does not require immediate or extensive further investigation unless the client reports symptoms of dizziness or syncope.

Choice D rationale

A Body Mass Index (BMI) of 29.75 kg/m falls within the overweight category (BMI 25.0-29.9 kg/m), nearing obesity (BMI ≥ 30.0 kg/m). While excess adiposity can contribute to menstrual irregularity due to estrogen production by adipose tissue, promoting anovulation, the irregular menses is the immediate clinical problem. The BMI itself is an important risk factor for future health issues but is not the most urgent aspect requiring immediate in-depth investigation compared to the abnormal bleeding pattern.

Choice A rationale

The insertion of any foreign object into the uterus, such as an intrauterine device (IUD), carries a risk of introducing pathogenic microorganisms, potentially leading to pelvic inflammatory disease (PID) or endometritis, particularly in the first few weeks after insertion. Strict aseptic technique is mandatory to minimize this transient risk, which stems from the passage of the device through the cervix.

Choice B rationale

One of the major benefits of IUDs is their immediate reversibility. Upon removal of the device, fertility returns quickly, often within the first menstrual cycle. This is a point of education that contrasts with hormonal methods, such as the injectable depot medroxyprogesterone acetate (DMPA), which can cause a delay in the return to fertility.

Choice C rationale

An intrauterine device prevents uterine implantation, but it does not prevent fertilization. If pregnancy occurs with an IUD in place, there is a significantly increased risk that the fertilized ovum will implant outside the uterus, most commonly in the fallopian tube, resulting in a potentially life-threatening ectopic pregnancy for the woman.

Choice D rationale

Uterine perforation is a rare but serious complication, occurring most often at the time of insertion when the sound or the IUD itself punctures the uterine wall, which can lead to intra-abdominal placement or damage to adjacent organs. Risk factors include a recently postpartum or lactating uterus, which is softer and more pliable.
