✳️ Urinary frequency is an expected physiologic change during early pregnancy, especially during the first trimester.

✳️ Pregnancy causes a substantial increase in maternal blood volume and cardiac output, which increases the amount of blood delivered to the kidneys.

✳️ Increased renal blood flow produces an increase in the glomerular filtration rate (GFR), causing the kidneys to filter a greater volume of fluid.

✳️ Increased filtration results in greater urine production, which contributes to the client's need to urinate more frequently.

✳️ The enlarging uterus can also place additional pressure on the urinary bladder, further contributing to urinary frequency during early pregnancy.

✳️ Urinary frequency by itself, without symptoms such as dysuria, fever, urgency with pain, or cloudy urine, is generally considered a normal pregnancy adaptation.

✳️ The nurse should reassure the client that this symptom is common while still encouraging adequate hydration throughout pregnancy.

✳️ The statement about increased blood volume and increased renal processing therefore provides the most appropriate explanation for this client's symptoms.

✍️ Human chorionic gonadotropin (hCG) rises rapidly during early pregnancy and supports the corpus luteum so that progesterone production can continue.

✍️ Early pregnancy is also associated with marked cardiovascular and renal adaptations that increase renal blood flow and glomerular filtration.

✍️ Increased kidney perfusion contributes to greater urine production and explains why frequent urination is common during the first trimester.

✍️ High hormonal activity during early pregnancy also contributes to symptoms such as fatigue, dizziness, nausea, and urinary frequency.

✍️ hCG concentrations generally rise rapidly during the first trimester and peak around the end of the first trimester before gradually declining.

✍️ Increased circulating hormones contribute to systemic vascular changes that can lower vascular resistance and sometimes produce lightheadedness or dizziness.

✍️ These hormonal and hemodynamic changes are considered normal adaptations that support the developing placenta and fetus.

✍️ Among the available choices, elevated hCG associated with increased renal blood flow and urinary frequency best explains the client's early-pregnancy symptoms.

🧿 A pregnant client who tests positive for Group B Streptococcus (GBS) should receive intrapartum antibiotic prophylaxis to reduce transmission to the newborn.

🧿 Penicillin G is the preferred antibiotic for most GBS-positive clients who do not have a significant penicillin allergy.

🧿 Antibiotics are administered during labor, because treatment before labor does not reliably eliminate maternal GBS colonization at the time of birth.

🧿 Intrapartum prophylaxis significantly reduces the risk of early-onset neonatal GBS disease, including sepsis, pneumonia, and meningitis.

🧿 GBS commonly colonizes the gastrointestinal and genitourinary tracts without producing symptoms in the pregnant client.

🧿 A positive GBS screening result therefore represents colonization, not necessarily an active maternal infection.

🧿 The antibiotic should ideally be initiated early enough during labor to provide effective fetal exposure before delivery, although indicated treatment should not be withheld if labor progresses quickly.

🧿 Administration of prescribed penicillin during labor is therefore the appropriate nursing action for a GBS-positive pregnant client.

🔆 The first trimester is the period of greatest vulnerability to many teratogens because major fetal organs are undergoing rapid formation.

🔆 Working in a paint manufacturing environment can expose a pregnant client to solvents, chemicals, heavy metals, or other industrial substances that may have teratogenic effects.

🔆 Personal protective equipment (PPE) can reduce exposure, but it does not necessarily eliminate occupational contact with potentially harmful substances.

🔆 Repeated workplace exposure can produce a greater cumulative risk than a brief or incidental environmental exposure.

🔆 During organogenesis, which primarily occurs during the early weeks of pregnancy, harmful chemical exposures can interfere with normal structural development.

🔆 Occupational risk assessment should therefore include the specific chemicals used, duration of exposure, ventilation, workplace safety controls, and effectiveness of PPE.

🔆 The pregnant client should be encouraged to discuss occupational exposures with the healthcare provider and workplace safety personnel so appropriate modifications can be made when necessary.

🔆 Among the situations listed, ongoing first-trimester occupational exposure in a paint manufacturing plant creates the greatest potential for significant teratogenic exposure.

👉 Maternal blood volume increases approximately 30% to 50% during pregnancy to meet the increased circulatory demands of the pregnant client and developing fetus.

👉 A major purpose of this expansion is to maintain adequate uteroplacental perfusion, which delivers oxygen and nutrients to the placenta and fetus.

👉 Increased vascular volume supports the dramatic rise in blood flow to the uterus and placenta as pregnancy progresses.

👉 Plasma volume increases more than red blood cell mass, producing the normal physiologic anemia of pregnancy through hemodilution.

👉 Expanded blood volume also helps support increased maternal cardiac output required to perfuse the uterus, kidneys, skin, and other tissues.

👉 The additional circulating volume provides a protective reserve against the expected blood loss associated with childbirth.

👉 Adequate maternal circulation is essential because placental exchange depends on sufficient blood flow through the uterine vessels.

👉 The statement that increased blood volume provides adequate perfusion of the placenta therefore best explains this normal pregnancy adaptation.

🖋️ Abdominal pain at 35 weeks of gestation requires additional assessment because it can indicate a pregnancy complication rather than an expected physiologic change.

🖋️ Persistent, severe, rhythmic, or localized abdominal pain may be associated with preterm labor, placental abruption, uterine activity, or another acute abdominal condition.

🖋️ The nurse should assess the onset, location, intensity, duration, and pattern of the pain to determine whether contractions or another pathologic process may be occurring.

🖋️ Assessment should also include the presence of vaginal bleeding, leakage of fluid, uterine tenderness, contractions, and changes in fetal movement.

🖋️ Placental abruption can present with abdominal or back pain, uterine tenderness, increased uterine tone, and vaginal bleeding, although bleeding may sometimes be concealed.

🖋️ Preterm labor can also produce regular contractions, pelvic pressure, low back pain, and abdominal cramping before 37 completed weeks of gestation.

🖋️ Maternal vital signs and fetal heart rate should be evaluated when significant abdominal pain is reported because maternal or fetal compromise may develop.

🖋️ Abdominal pain therefore requires additional assessment because it may represent a serious obstetric complication.

❤️ A biophysical profile (BPP) is a noninvasive prenatal assessment used to evaluate fetal well-being and identify possible evidence of fetal hypoxia.

❤️ The BPP combines ultrasound assessment with evaluation of fetal heart rate reactivity, usually through a nonstress test.

❤️ Ultrasound is used to assess fetal breathing movements, gross body movements, fetal tone, and amniotic fluid volume.

❤️ A nonstress test may be included to evaluate whether the fetal heart rate accelerates appropriately with fetal movement.

❤️ Each component is assigned a score, and the combined score helps estimate the likelihood of adequate fetal oxygenation and neurologic function.

❤️ Normal fetal movement, tone, and breathing activity generally indicate that the central nervous system is receiving adequate oxygen.

❤️ Reduced biophysical activity or abnormal amniotic fluid findings can indicate possible uteroplacental insufficiency or fetal compromise and may require additional evaluation.

❤️ The nurse should therefore explain that the BPP uses ultrasound and fetal heart rate assessment to evaluate fetal well-being and oxygenation.

🏵️ An Rh-negative pregnant client who experiences a spontaneous abortion can be exposed to Rh-positive fetal red blood cells entering the maternal circulation.

🏵️ Exposure to fetal Rh-positive cells can cause the maternal immune system to become sensitized and produce anti-D antibodies.

🏵️ Once maternal sensitization has occurred, these antibodies can cross the placenta during a future Rh-positive pregnancy and destroy fetal erythrocytes.

🏵️ This immune reaction can result in hemolytic disease of the fetus and newborn, including fetal anemia, hydrops fetalis, or severe neonatal hyperbilirubinemia.

🏵️ Rho(D) immune globulin prevents maternal sensitization by binding Rh-positive fetal erythrocytes before the maternal immune system mounts an antibody response.

🏵️ Rho(D) immune globulin is indicated after sensitizing events such as pregnancy loss, vaginal bleeding, abdominal trauma, invasive procedures, and delivery of an Rh-positive infant when appropriate.

🏵️ Administration should occur within the recommended time period after the sensitizing event to provide effective prophylaxis against Rh alloimmunization.

🏵️ Because the question specifically asks which action reduces complications in future pregnancies, administering prescribed Rho(D) immune globulin is the priority intervention.

✏️ A transabdominal ultrasound during the first trimester is often performed with a full urinary bladder to improve visualization of the uterus and developing pregnancy.

✏️ A distended bladder helps displace bowel loops and intestinal gas away from the pelvis, reducing interference with ultrasound imaging.

✏️ The full bladder also acts as an acoustic window, allowing ultrasound waves to travel more effectively through fluid than through gas-filled bowel.

✏️ Better transmission of ultrasound waves improves visualization of the uterus, gestational sac, fetus, and surrounding pelvic structures.

✏️ Drinking approximately a quart of water before the study helps produce the necessary bladder distention for early transabdominal imaging.

✏️ The client is generally instructed to avoid voiding until the examination is completed, unless directed otherwise by the sonographer.

✏️ Full-bladder preparation is particularly useful during early pregnancy because the uterus remains relatively low within the pelvis.

✏️ Drinking water approximately 1 to 2 hours before the procedure is therefore the appropriate teaching for a first-trimester transabdominal ultrasound.

💜 A nonstress test (NST) evaluates fetal heart rate accelerations in response to spontaneous fetal movement and is used to assess fetal well-being.

💜 At 38 weeks of gestation, a reactive NST typically requires at least two accelerations of 15 beats/min above baseline lasting at least 15 seconds within a 20-minute period.

💜 The fetal heart rate baseline of 135 beats/min is within the expected normal range of approximately 110 to 160 beats/min.

💜 Absence of accelerations during the first 20 minutes does not automatically indicate fetal distress because the fetus may be experiencing a normal sleep cycle.

💜 Fetal sleep cycles may last approximately 20 to 40 minutes, so the NST is commonly extended to 40 minutes before it is classified as nonreactive.

💜 Offering juice or a snack may increase maternal glucose availability and can sometimes stimulate fetal activity, although other stimulation methods such as vibroacoustic stimulation may also be used according to facility protocol.

💜 If the NST remains nonreactive after an adequate observation period, further fetal evaluation such as a biophysical profile or contraction stress test may be considered based on the clinical situation and provider orders.

💜 Continuing the NST for another 20 minutes is therefore the appropriate next action because a normal fetal sleep cycle must first be excluded.
