Question

A nurse is teaching a prenatal class about the role of the placenta. Which hormone produced by the placenta helps maintain the pregnancy after the first trimester?

Answer 1

Correct Answers:

Progesterone

Rationale :

💠After the first trimester, the placenta becomes the main producer of progesterone, which is vital for maintaining pregnancy.

💠Progesterone stabilizes the endometrial lining (decidua), preventing uterine contractions that could lead to miscarriage.

💠It promotes uterine relaxation and supports the growth of maternal tissues, including breast tissue, in preparation for lactation.

💠This hormone also suppresses maternal immune responses against the fetus, ensuring that the body does not reject the developing baby.

💠Without adequate progesterone, the pregnancy could not be sustained, making it a key hormone in fetal survival and uterine maintenance.

Answer 2

Correct Answers:

Offer to schedule a meeting that includes the client, her support person, and the healthcare provider to discuss her concerns and beliefs.

Rationale :

➡️When a client’s cultural or religious beliefs influence her perception or acceptance of pregnancy and care, the nurse’s role is to promote open, respectful communication.

➡️By scheduling a meeting with the client, her support person, and the healthcare provider, the nurse encourages collaborative decision-making that honors the client’s values while ensuring safe and effective care.

➡️This approach demonstrates cultural competence, supports patient autonomy, and helps reduce anxiety or conflict between the client’s beliefs and medical recommendations.

➡️Including the client’s support person fosters trust and provides emotional reinforcement, making the client more likely to engage in prenatal care.

➡️The nurse acts as an advocate and facilitator, ensuring that care remains individualized and respectful of diverse belief systems.

Answer 3

Correct Answers:

Urine output and urine protein level

Rationale :

💠Severe preeclampsia threatens renal perfusion, so tracking urine output (goal ≥30 mL/hr) is essential to detect evolving acute kidney injury.

💠Ongoing assessment of proteinuria (dipstick or 24-hr collection) reflects glomerular endothelial damage, a hallmark of preeclampsia severity.

💠Together, these parameters guide timely escalation (e.g., magnesium sulfate, delivery planning) and help evaluate response to antihypertensives.

💠They also provide early warning for HELLP progression and fluid shifts, informing IV fluid restriction to avoid pulmonary edema.

💠Because vital signs, weight, DTRs, and FHR are already documented, renal status and protein loss are the most critical missing routine monitors for this client.

Answer 4

Correct Answers:

Verbalizing confidence in managing changes during pregnancy.

Rationale :

🔷An effective coping outcome is the client’s self-efficacy, demonstrated by expressing confidence in handling pregnancy-related changes.

🔷This reflects integration of education, resources, and support, indicating interventions (teaching, counseling, referrals) achieved their goal.

🔷Positive reframing and problem-focused coping typically appear as statements of capability and planfulness, which reduce anxiety.

🔷Verbalized confidence correlates with better prenatal self-care adherence (appointments, nutrition, warning sign recognition).

🔷It is a measurable behavioral indicator in nursing outcomes (e.g., Coping or Readiness for Enhanced Coping) that the care plan is effective.

Answer 5

Correct Answers:

Prioritize folic acid intake to support neural tube development

Rationale :

🔶In the first trimester, folate is critical for neural tube closure (by week 4–6), making folic acid a top nutritional priority.

🔶Nausea/vomiting can reduce intake, so reinforcing daily folic acid (≥400–600 mcg) ensures protection despite decreased meal volume.

🔶Adequate folate lowers risk of neural tube defects (e.g., spina bifida, anencephaly), a non-negotiable preventive target in early pregnancy.

🔶Nurses should pair folate guidance with small, frequent, bland snacks to improve tolerance, ensuring the supplement is consistently absorbed.

🔶While calcium and other nutrients matter, timing-sensitive folate remains the priority during early organogenesis.

Answer 6

Correct Answers:

Notify the client that the snack is not appropriate.

Rationale :

💎Clients with phenylketonuria (PKU) must avoid phenylalanine, found in aspartame (diet soda) and high-protein foods like turkey sticks.

💎The first nursing action is immediate client education and snack replacement to prevent teratogenic neurotoxicity from elevated maternal Phe levels.

💎Early correction protects fetal brain development, as high maternal Phe is linked to microcephaly, developmental delay, and congenital anomalies.

💎After correcting the choice, the nurse can collaborate with the dietitian to reinforce a low-Phe, medically supervised diet.

💎Prompt, clear feedback builds dietary adherence, crucial throughout pregnancy to maintain safe maternal Phe ranges.

Answer 7

Correct Answers:

Blood pressure of 124/68 mmHg

Rationale :

🟣In gestational hypertension, the therapeutic goal of nifedipine (vasodilation) and low-dose aspirin (anti-platelet placental benefit) is BP control.

🟣A reading of 124/68 mmHg indicates effective reduction of afterload and decreased risk of preeclampsia and placental complications.

🟣Controlled BP reduces the likelihood of end-organ injury, fetal growth restriction, and preterm birth.

🟣Aspirin 81 mg particularly helps mitigate abnormal placentation and preeclampsia progression in at-risk pregnancies.

🟣This value demonstrates the medications are achieving the desired hemodynamic targets without hypotension.

Answer 8

Correct Answers:

"Standard precautions are used for all clients, including those with HIV. Isolation is not required after delivery."

Rationale :

🔵HIV is managed with standard precautions (hand hygiene, gloves as needed); routine isolation is not indicated postpartum.

🔵Transmission risks are addressed by antiretroviral therapy, delivery plan, and neonatal prophylaxis, not by maternal isolation.

🔵Placing an HIV-positive client in isolation without indication may contribute to stigma and does not enhance safety.

🔵The same infection-prevention principles apply as for any postpartum client—appropriate PPE for blood/body fluids only.

🔵Clear education reduces misconceptions, supports psychological safety, and promotes trust in the care plan.

Answer 9

Correct Answers:

Early pregnancy loss
Threatened abortion

Rationale :

Early pregnancy loss:

🟢Low progesterone compromises endometrial support, increasing likelihood of failed implantation/placental maintenance despite positive hCG.

🟢Insufficient progesterone reduces uterine quiescence and decidual stability, precipitating pregnancy failure.

🟢Clinically, low levels correlate with nonviable gestation or ectopic, but in the context given, the classic association is early loss.

🟢Monitoring trends with serial hCG and ultrasound confirms viability and guides management.

🟢Progesterone supplementation may be considered in select cases per provider protocol, but low levels signal risk.

Threatened abortion:

🟢Threatened abortion involves first-trimester bleeding with a closed cervix where progesterone may be low, jeopardizing pregnancy continuation.

🟢The hormone’s role in maintaining the endometrium and relaxing uterine muscle means deficiency can present with symptoms of threatened loss.

🟢Identifying low progesterone prompts close follow-up, possible progesterone support, and activity/bleeding precautions.

🟢Ultrasound is used to assess intrauterine location and cardiac activity, while labs track hormonal trends.

🟢Early, targeted intervention may improve the chance of ongoing viability in select scenarios.

Answer 10

Correct Answers:

"I understand that amniocentesis is a procedure to obtain a sample of amniotic fluid for genetic testing."

Rationale :

🔷Amniocentesis at 15–20 weeks involves inserting a needle through the maternal abdomen into the amniotic sac to withdraw amniotic fluid for genetic and chromosomal testing.

🔷The sample allows assessment for genetic abnormalities such as Down syndrome, neural tube defects, or metabolic disorders.

🔷The nurse must ensure the client knows that fasting is not required and that this test is primarily diagnostic, not for fetal monitoring.

🔷Ultrasound guidance is used during the procedure to avoid injury to the fetus and placenta.

🔷Understanding the purpose of the test indicates accurate knowledge and readiness for the procedure.
