In caring for the premature infant, the nurse must continually assess hydration status. Parameters to assess would include all of the following except:
Select one:
Daily weight.
Consistency of stool.
Volume of urine output.
Blood pH.
The Correct Answer is D
Choice A Reason: Daily weight. This is an incorrect answer that indicates a valid parameter to assess hydration status. Daily weight is a measure of the body mass that can reflect changes in fluid balance. Daily weight can help detect fluid loss or gain in premature infants, who are more prone to dehydration or overhydration due to immature renal function and high insensible water loss.
Choice B Reason: Consistency of stool. This is an incorrect answer that indicates a valid parameter to assess hydration status. Consistency of stool is a measure of the texture and form of feces that can reflect changes in fluid intake and absorption. Consistency of stool can help identify diarrhea or constipation in premature infants, who are more susceptible to gastrointestinal problems such as necrotizing enterocolitis or feeding intolerance.
Choice C Reason: Volume of urine output. This is an incorrect answer that indicates a valid parameter to assess hydration status. Volume of urine output is a measure of the amount of urine produced and excreted by the kidneys that can reflect changes in fluid balance and renal function. Volume of urine output can help monitor hydration status and kidney function in premature infants, who are more vulnerable to fluid overload or deficit and renal impairment.
Choice D Reason: Blood pH. This is because blood pH is a measure of the acidity or alkalinity of the blood, which reflects the balance between carbon dioxide and bicarbonate in the body. Blood pH is not a direct indicator of hydration status, which refers to the amount of water and electrolytes in the body. Hydration status can affect blood pH, but blood pH can also be influenced by other factors such as respiratory or metabolic disorders.

Correct Answer is D
Explanation
Choice A Reason: Rule out a suspected hydatidiform mole. This is an incorrect answer that describes an unlikely condition for this client. A hydatidiform mole is a type of gestational trophoblastic disease where abnormal placental tissue develops instead of a normal fetus. A hydatidiform mole can cause vaginal bleeding, hyperemesis gravidarum (severe nausea and vomiting), preeclampsia, and hyperthyroidism. A hydatidiform mole usually causes a fundal height measurement that is larger than expected for gestational age, not smaller.
Choice B Reason: Assess for congenital anomalies. This is an incorrect answer that implies that the client has not had a previous ultrasound to screen for fetal anomalies. Congenital anomalies are structural or functional defects that are present at birth, such as cleft lip, spina bifida, or Down syndrome. Ultrasound can detect some congenital anomalies by visualizing the fetal anatomy and morphology. However, ultrasound screening for fetal anomalies is usually done between 18 and 22 weeks of gestation, not at 32 weeks.
Choice C Reason: Determine fetal presentation. This is an incorrect answer that suggests that the client has an uncertain fetal presentation. Fetal presentation is the part of the fetus that is closest to the cervix, such as vertex (head), breech (butocks or feet), or transverse (shoulder). Fetal presentation can affect the mode and outcome of delivery. Ultrasound can determine fetal presentation by locating the fetal head and spine. However, fetal presentation can also be assessed by abdominal palpation or vaginal examination, which are simpler and less invasive methods.
Choice D Reason: Monitor fetal growth. This is because fundal height measurement is a method of estimating fetal size and gestational age by measuring the distance from the pubic symphysis to the top of the uterus (fundus) in centimeters. A fundal height measurement that is significantly smaller or larger than expected for gestational age may indicate intrauterine growth restriction (IUGR) or macrosomia, respectively. IUGR means that the fetal growth is slower than expected for gestational age, which can increase the risk of fetal distress, hypoxia, acidosis, and stillbirth. Macrosomia means that the fetal weight is higher than expected for gestational age, which can increase the risk of birth injuries, shoulder dystocia, cesarean delivery, and hypoglycemia. Ultrasound is a more accurate way of assessing fetal size and growth by measuring various parameters such as biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL). Ultrasound can also detect other factors that may affect fetal growth such as placental function, amniotic fluid volume, umbilical cord blood flow, and fetal anomalies.
Correct Answer is A
Explanation
Choice A Reason: "If I go too long overdue, the amniotic fluid volume can become too low for my baby to be safe." This is a correct answer that indicates that the client understands one of the Reasons for induction of labor at 42 weeks' pregnancy.
Choice B Reason: "My baby took longer to grow, and now she's ready to be born." This is an incorrect answer that shows a misconception about fetal growth and development. Fetal growth does not depend on gestational age alone, but also on genetic, maternal, placental, and environmental factors. A post-term fetus does not necessarily grow faster or larger than a term fetus. In fact, some post-term fetuses may experience intrauterine growth restriction (IUGR), which means slower than expected growth for gestational age.
Choice C Reason: "I don't really need this induction, my baby will come whenever he wants to." This is an incorrect answer that reveals a lack of awareness or acceptance of the need for induction of labor at 42 weeks' pregnancy. Induction of labor is recommended for post-term pregnancies to prevent potential complications such as fetal distress, stillbirth, or maternal hemorrhage.
Choice D Reason: "Since I am so tired of being pregnant, I am being induced." This is an incorrect answer that implies that induction of labor is based on maternal preference or convenience rather than medical indication. Induction of labor should not be done without a valid Reason or informed consent, as it carries some risks such as failed induction, prolonged labor, infection, uterine rupture, or cesarean delivery.
