D447 Women and Children - Set 1 - Part 1

Correct Answer: Focus on nutrient density for now

The first trimester requires no additional caloric intake since the fetus is still very small. The nurse should emphasize choosing nutrient-dense foods over simply eating more calories at this early stage. Option a is incorrect because 340 additional calories per day is the guideline for the second trimester, not the first. Applying this increase too early does not align with the actual metabolic demands of early pregnancy. Option b is incorrect because doubling caloric intake far exceeds what pregnancy requires at any stage. Even the third trimester only calls for roughly 450 additional calories per day, which is nowhere near doubling total intake. Option d is incorrect because 450 additional calories per day corresponds to the third trimester recommendation when fetal growth is most rapid. At eight weeks gestation the patient does not yet require any caloric increase.

Correct Answer: Folic acid 400 to 800 mcg daily

Folic acid is the single most important supplement for preventing neural tube defects and should ideally begin before conception. Starting supplementation months before pregnancy provides the greatest protective benefit for early fetal development. Option b is incorrect because although iron is essential during pregnancy to prevent anemia and support expanding blood volume, it becomes most critical during pregnancy itself rather than being the top preconception priority over folic acid. Option c is incorrect because calcium supports fetal bone and teeth development during pregnancy but does not carry the same urgency as folic acid for preconception supplementation, since neural tube closure occurs very early in gestation. Option d is incorrect because vitamin D aids calcium absorption and is important throughout pregnancy, but it does not match the preconception urgency of folic acid, which directly prevents structural defects during the earliest weeks of development.

Correct Answer: Take it with a source of vitamin C

Vitamin C significantly enhances iron absorption in the gastrointestinal tract. Advising the patient to pair her iron supplement with citrus juice or another vitamin C source is a standard evidence-based nursing recommendation. Option a is incorrect because milk contains calcium, which competes with iron for absorption in the gut. Taking iron with dairy products reduces the amount of iron the body can absorb and undermines the purpose of supplementation. Option b is incorrect because calcium directly interferes with iron absorption when taken simultaneously. Pairing an iron supplement with a calcium tablet would decrease iron bioavailability rather than enhancing it as the patient needs. Option c is incorrect because antacids raise gastric pH and reduce the acidic environment that facilitates iron absorption. Taking iron alongside an antacid would impair absorption and counteract the therapeutic intent of the supplement.

Correct Answer: Listeria monocytogenes

Listeria monocytogenes is uniquely dangerous in pregnancy since it can cross the placenta and directly infect the fetus. Unpasteurized soft cheeses such as brie and feta are classic vehicles for this organism. Option a is incorrect because while Salmonella causes serious gastrointestinal illness and is associated with undercooked eggs and poultry, it does not characteristically cross the placenta to infect the fetus the way Listeria does. Option c is incorrect because Toxoplasma gondii is primarily associated with undercooked meat and cat feces rather than soft cheeses. Although it can cross the placenta, unpasteurized dairy is not its recognized transmission route. Option d is incorrect because Escherichia coli causes foodborne gastrointestinal illness but is not specifically linked to soft unpasteurized cheeses nor recognized as a major placental transmission pathogen in pregnancy in the same way.

Correct Answer: 15 to 25 pounds

A pre-pregnancy BMI of 27.4 falls in the overweight category. Current guidelines recommend a total pregnancy weight gain of 15 to 25 pounds for overweight women to optimize maternal and fetal outcomes. Option b is incorrect because a recommended gain of 28 to 40 pounds applies to women who are underweight before pregnancy with a BMI below 18.5. This range would be excessive for a patient in the overweight category. Option c is incorrect because a gain of 25 to 35 pounds is the recommendation for women with a normal pre-pregnancy BMI between 18.5 and 24.9. Applying this range to an overweight patient could promote unnecessary excess weight gain. Option d is incorrect because a gain of 11 to 20 pounds is recommended for women classified as obese with a BMI of 30 or above. Although this patient is overweight, her BMI does not reach the obesity threshold requiring this restriction.

Correct Answer: Plasma volume expands faster than red cells

Pregnancy causes plasma volume to increase by 30 to 50 percent while red blood cell mass rises more slowly. This dilution effect lowers hemoglobin concentration and is a normal physiologic adaptation rather than a pathologic finding. Option b is incorrect because while fetal demands on maternal iron stores do increase during pregnancy, the primary reason for a mildly lower hemoglobin at 30 weeks is hemodilution from plasma expansion rather than iron depletion by the fetus. Option c is incorrect because a hemoglobin of 11.3 g/dL during the third trimester falls within the expected range for pregnant women. True iron-deficiency anemia in pregnancy is typically identified when hemoglobin drops below 11 g/dL along with other confirmatory findings. Option d is incorrect because initiating supplemental iron is not automatically warranted for a hemoglobin level that falls within the normal physiologic range for pregnancy. This value reflects expected hemodilution rather than a deficiency requ

Correct Answer: Both findings are expected at this stage

During the second trimester blood pressure normally dips due to decreased systemic vascular resistance, and heart rate increases by 10 to 15 beats per minute above baseline. These asymptomatic findings reflect typical cardiovascular adaptations. Option a is incorrect because early hemorrhage presents with tachycardia paired with hypotension and accompanying symptoms such as pallor, anxiety, and weakness. This asymptomatic patient with stable vitals does not fit a hemorrhage pattern at all. Option b is incorrect because maternal heart rate alone does not indicate fetal distress. Fetal status is assessed through fetal heart rate monitoring, not through interpreting the mother's pulse, which is elevated due to normal pregnancy physiology. Option d is incorrect because a blood pressure of 100/62 during the second trimester is within the expected range given the normal decrease in systemic vascular resistance. Urgent intervention would be warranted for severe hypertension, not this fin

Correct Answer: Preeclampsia with worsening features

The combination of severe headache, visual disturbances, and sudden edema after 20 weeks gestation represents the classic warning signs of preeclampsia with severe features. This requires urgent evaluation to prevent progression to eclampsia. Option a is incorrect because although migraines with aura can occur during pregnancy, the simultaneous presentation of severe headache, vision changes, and new-onset swelling at 34 weeks must be presumed to be preeclampsia until proven otherwise. Option c is incorrect because while mild dependent edema is common in the third trimester, the triad of severe headache, visual changes, and sudden ring tightness represents a dangerous pattern that cannot be dismissed as normal fluid retention. Option d is incorrect because gestational hypertension without complications would not produce severe headache and visual disturbances. The presence of these systemic symptoms elevates the clinical concern beyond simple elevated blood pressure to preeclampsia wit

Correct Answer: Blood pressure 162/114 with blurred vision

Severe hypertension at or above 160/110 combined with visual disturbances signals imminent risk of eclamptic seizure, stroke, or placental abruption. This patient requires immediate assessment and intervention above all others presented. Option b is incorrect because a temperature of 37.8 Celsius is only mildly elevated and paired with nonspecific fatigue. While infection should be monitored, this presentation does not carry the same acute life-threatening urgency as severe hypertension with neurological symptoms. Option c is incorrect because a heart rate of 92 bpm is within the expected range during pregnancy and occasional dizziness can result from normal positional blood pressure changes. This presentation does not suggest an immediately dangerous condition. Option d is incorrect because a blood pressure of 128/82 with trace ankle edema is a common and generally benign finding during pregnancy. Mild dependent edema alone without hypertension or other systemic symptoms does not indi

Correct Answer: Assess for concealed hemorrhage immediately

Tachycardia paired with hypotension, pallor, and lightheadedness in a pregnant patient is the classic presentation of hemorrhagic shock. Minimal visible bleeding with these vital sign changes strongly suggests concealed internal hemorrhage requiring immediate assessment. Option b is incorrect because while repositioning can improve blood pressure through venous return, it does not address the underlying cause. Prioritizing comfort over identifying a potential life-threatening hemorrhage delays critical intervention and assessment of the source. Option c is incorrect because oral fluids are insufficient to manage hemodynamic instability caused by significant hemorrhage. This patient requires intravenous access, fluid resuscitation, and identification of the bleeding source rather than simply drinking fluids by mouth. Option d is incorrect because waiting 30 minutes to reassess a patient showing tachycardia, hypotension, and pallor risks catastrophic deterioration. These are signs of act

Correct Answer: Below 95 mg/dL

The established fasting glucose target for gestational diabetes management is below 95 mg/dL. Maintaining this threshold reduces risks of fetal macrosomia, neonatal hypoglycemia, and other complications associated with maternal hyperglycemia during pregnancy. Option a is incorrect because a fasting glucose of 110 mg/dL exceeds the recommended upper limit of 95 mg/dL for gestational diabetes. Consistently fasting at this level would indicate inadequate glucose control and potentially warrant medication adjustment. Option c is incorrect because 140 mg/dL is far above the acceptable fasting range and more closely relates to screening thresholds used during the one-hour glucose tolerance test. Using this as a fasting target would allow dangerously poor glucose control. Option d is incorrect because while 80 mg/dL is a safe glucose level, stating it must be exactly that value is clinically inaccurate. The target is defined as below 95 mg/dL rather than a single fixed number.

Correct Answer: Shoulder dystocia during delivery

Macrosomic infants born to mothers with poorly controlled gestational diabetes carry significantly elevated risk for shoulder dystocia during vaginal delivery. The large fetal shoulders can become impacted behind the maternal pubic symphysis, creating an obstetric emergency. Option a is incorrect because while neonatal jaundice can occur in infants of diabetic mothers, it is not the primary delivery-related complication the nurse should anticipate when a macrosomic infant is being delivered vaginally through the birth canal. Option b is incorrect because fetal growth restriction is the opposite of what occurs with poorly controlled gestational diabetes. Maternal hyperglycemia drives excessive fetal growth and macrosomia rather than restricted growth or placental insufficiency. Option d is incorrect because oligohydramnios is associated with conditions like uteroplacental insufficiency and renal anomalies rather than gestational diabetes. Poorly controlled gestational diabetes more comm

Correct Answer: Four times daily including a fasting check

The standard gestational diabetes monitoring schedule requires four daily glucose checks: one fasting measurement each morning and three postprandial checks taken two hours after each main meal to assess glycemic control throughout the day. Option b is incorrect because checking glucose only once each morning provides incomplete information about how the patient's body handles carbohydrates from meals throughout the day. Postprandial values are essential for guiding dietary and medication adjustments. Option c is incorrect because random glucose checks twice daily do not provide the structured data needed to evaluate fasting levels and postmeal responses. Effective gestational diabetes management requires timed measurements at specific intervals relative to meals. Option d is incorrect because checking glucose only four times per week is far too infrequent to capture meaningful patterns or detect dangerous glucose excursions. Daily monitoring is necessary to make timely adjustment

Correct Answer: Focus on complex carbohydrates and fiber

Complex carbohydrates and fiber-rich foods produce slower, more gradual rises in blood glucose compared to simple sugars. Diet modification emphasizing these foods is the recommended first-line intervention for managing gestational diabetes effectively. Option a is incorrect because completely eliminating carbohydrates is neither recommended nor safe during pregnancy. Carbohydrates are the primary energy source and prevent ketosis, which poses risks to fetal brain development when maternal glucose is severely restricted. Option b is incorrect because fruit juices are concentrated sources of simple sugars that cause rapid blood glucose spikes. Whole fruits with their natural fiber content are a better choice because fiber slows sugar absorption and improves glycemic control. Option c is incorrect because removing all grains and replacing them with protein-only meals creates a nutritionally imbalanced diet that risks ketosis. Gestational diabetes management focuses on choosing better car

Correct Answer: Rescreening at 6 to 12 weeks postpartum

Women who had gestational diabetes carry significantly increased risk for developing type 2 diabetes later in life. Rescreening with a glucose tolerance test at 6 to 12 weeks postpartum identifies patients who need ongoing monitoring and intervention. Option a is incorrect because gestational diabetes frequently recurs in subsequent pregnancies and signals elevated lifetime risk for type 2 diabetes. Telling the patient it will never return provides false reassurance and may discourage important follow-up care. Option c is incorrect because discontinuing all glucose monitoring after delivery ignores the established risk for persistent glucose intolerance. Postpartum rescreening is a standard recommendation to catch early development of type 2 diabetes in these patients. Option d is incorrect because most patients with diet-controlled gestational diabetes do not require insulin after delivery. The insulin resistance driven by placental hormones typically resolves once the placenta is del

Correct Answer: This is her first pregnancy at age 37

Nulliparity and maternal age over 35 are both established risk factors for preeclampsia. A first pregnancy at age 37 combines two significant risk factors, making this history finding the most relevant to the patient's current presentation. Option a is incorrect because regular exercise three times per week is a healthy behavior associated with improved cardiovascular fitness during pregnancy. Physical activity is not a risk factor for preeclampsia and may actually offer some protective benefit. Option b is incorrect because having a previous full-term delivery means the patient is multiparous, which actually reduces preeclampsia risk compared to nulliparity. A prior uncomplicated pregnancy is generally considered a favorable history finding for this condition. Option d is incorrect because a pre-pregnancy BMI of 22 falls within the normal weight range. Elevated BMI above 30 is a recognized risk factor for preeclampsia, but a normal BMI does not contribute increased risk for the c

Correct Answer: Hold the infusion and notify the provider

Absent deep tendon reflexes are the earliest reliable warning sign of magnesium toxicity. The nurse should immediately hold the magnesium infusion and notify the provider before toxicity progresses to respiratory depression, cardiac arrest, or coma. Option b is incorrect because calcium gluconate is the antidote for magnesium toxicity but is administered only when toxicity has advanced to respiratory depression or cardiac compromise. The first nursing action for absent reflexes is stopping the infusion and notifying the provider. Option c is incorrect because increasing the infusion rate would worsen magnesium toxicity. The patient is already showing clear signs of excessive magnesium levels, and any increase in the infusion rate would accelerate the progression toward life-threatening complications. Option d is incorrect because continuing the infusion and waiting to recheck in one hour ignores a critical warning sign that requires immediate action. Absent deep tendon reflexes signal

Correct Answer: Deep tendon reflexes, respirations, and urine output

Deep tendon reflexes, respiratory rate, and urine output are the three critical parameters for monitoring magnesium sulfate safety. Loss of reflexes signals early toxicity, respiratory depression indicates advancing toxicity, and decreased urine output impairs magnesium excretion. Option a is incorrect because while fetal heart rate monitoring is important during preeclampsia management, maternal weight and dietary intake are not the primary indicators used to detect magnesium sulfate toxicity during continuous infusion or before repeated doses. Option b is incorrect because skin turgor, capillary refill, and temperature are general assessment parameters that help evaluate hydration and perfusion status but do not specifically target the early warning signs of magnesium sulfate toxicity progression. Option c is incorrect because blood glucose, hemoglobin, and platelet count are laboratory values relevant to overall maternal health and may be part of preeclampsia workup but are not the

Correct Answer: Its primary purpose is seizure prevention

The primary indication for magnesium sulfate in severe preeclampsia is seizure prophylaxis rather than blood pressure control. It acts as a central nervous system depressant that prevents eclamptic seizures, which is why it is prioritized despite toxicity risks. Option a is incorrect because magnesium sulfate is not classified as an antihypertensive medication and does not effectively lower blood pressure on its own. Separate antihypertensive agents are typically administered alongside magnesium to manage the elevated blood pressure component. Option c is incorrect because magnesium sulfate does not replace the need for antihypertensive medications in severe preeclampsia. Patients frequently require additional medications such as labetalol or hydralazine to bring dangerously elevated blood pressure under control. Option d is incorrect because magnesium sulfate does not reverse the underlying pathophysiology of preeclampsia. The only definitive treatment for preeclampsia is delivery of

Correct Answer: Checking for protein that supports the diagnosis

Proteinuria is a key diagnostic criterion for preeclampsia alongside hypertension developing after 20 weeks gestation. Urine protein assessment helps confirm the diagnosis and guides the clinical team in determining the severity of the condition. Option a is incorrect because urine glucose screening relates to gestational diabetes evaluation rather than preeclampsia. While both conditions can occur during pregnancy, the urine collection in the context of suspected preeclampsia specifically targets protein detection. Option b is incorrect because while creatinine clearance may be part of a comprehensive preeclampsia workup, the primary purpose of urine testing in a patient with suspected preeclampsia is detecting proteinuria rather than measuring creatinine as the main diagnostic focus. Option d is incorrect because screening for urinary tract bacteria is performed with a urine culture to evaluate for infection. The urine test in the setting of suspected preeclampsia is focused on ident
